Review: RAVPower 23,000mAh Power Bank

When it comes to high capacity power banks, a lot can be done with them. This is mainly because high capacity power banks don’t aim to be small like mini power banks, and even though power banks, in general, are all portable; high capacity ones don’t have to be the most portable. Instead, the is the aim is to have a lot of capabilities with the power that it has. These kinds of power banks go further with not only with their power capacities but also their charging ways.

This RAVPowe 23,000mAh power bank is such a power bank that holds onto those capabilities because it has 3 very useful ways to charge your devices.

Power

Power Capacity:

It has a high initial power capacity of 23,000mAh and for good reasons too, because the power bank can charge 2 USB chargeable devices as well as a Laptop using its DC Output port. With that said, the Output power capacity that you’re going to receive is going to depend on how you’re using the power bank. This is because using all 3 of the charging options is going make more conversion of power to happen and then you have more energy going through multiple charging cables and power is lost there too.

With that said, this power bank actually has a very good conversion rate of 75% and that means you’re going to be receiving about 17,200mAh of usable power capacity. It can still fluctuate depending on how you’re using the power bank, but the average conversion rate is 75%.

RAVPower for Smartphones

Most smartphones are going to be able to charge 6 times or more to their full power. Even the high-capacity smartphones like the Galaxy S7 and Google Pixel that have battery capacities at or near 3,000mAh are going to be able to charge 6 times to their full power. So smartphones that have low capacities than those are going to be able to charge a lot more times.

RAVPower for Mini Tablets

The power bank is also capable of charging tablets numerous times over. If you’re charging mini tablets like the iPad Mini 4 with its power capacity of 5,124mAh or a Galaxy Tab with a battery capacity of 4,000mAh, you’re going to be able to get about 3 full charges. An iPad Mini 2 will be able to get 2.5 full charges because it has a slightly larger power capacity of 6,470mAh.

RAVPower for Full-Sized Tablets

If you plan on charging a Full-Sized 12 inch iPad with a capacity of 10,000mAh then that’s possible too because this RAVPower power bank is able to charge it 1.5 times.

RAVPower for Laptops

Last but not least, since this power bank can charge laptops, you also have to consider a number of times that it can charge yours. In this case, we’re targeting a Dell Inspiron that has a battery capacity of 7,800mAh. If you do plan on charging a Dell laptop with a battery capacity that large, then it’s going to result in 2 full charges for a laptop. Not bad considering that this is a power bank and you sit wherever you want while the power bank charges your laptop.

Output Charging:

There are 3 charging options to use.

USB Ports:

The speeds of the USB ports are quite odd. This is because 1 of the ports has a charging speed of 5V/2.5A and the other one is capable of outputting 5V/1.0A.

You should always use the 5V/2.5A port first because it’s going to give you the faster-charging speed and only use the other port if you plan on charging 2 USB devices at once. With that said, the power distribution of both of the ports is quite bad because one port has a lot of power and the other one just has a very slow charging speed.

The usual case with these high capacity power bank is charging power is shared through each of the ports. The Max Output of 3.5A with the USB ports would be best used if each of the two ports were able to Output 5V/2.4A, and so that way there wouldn’t be a compromise with one port.

DC Charging:

On the DC Charging side, the DC Port is able to deliver a charging speed of 9V/12V/16V/19V/20V – 4.5A.

4.5 Amps is the Max Output of the power bank. You have to note what the charging power requirements are for your laptop if you want it to charge at its max charging speed.

With that said, it’s quite amazing that this power bank is able to charge 3 devices at once, it’s just the 1 USB port that only has a charging speed of 5V/1.0A isn’t a very smart design choice to have with this power bank.

Input Charging:

The RAVPower power bank uses a DC Input to recharge itself because it’s a much faster way than using a Micro-USB method of recharging. The recharging speed is 12-24V / 2A and as a result, the power bank will be able to recharge within 6 hours.

It’s a very fast recharge speed and we’re glad that RAVPower went with a more efficient way of recharging.

Design

Size and Weight:

The main thing to remember with power banks that have high power capacities and that are also able to charge laptops is that they’re going to be quite large.

This RAVPower power bank has a length of 7.2 inches, a width of 4.8 inches and a thickness of 0.7 inches. The weight of the power bank is 1.2 pounds. So it’s large and heavy, and clearly not the type of power bank that you’d hold and charge a smartphone with. With that said, it’s still portable in the way that you can take it with you anywhere, place it down and charge your devices comfortably.

Functional Components:

On the Side:

All charging parts of the power bank can be found on the side; and that’s where you’ll be able to find the DC Output and Input ports, as well as the 2 USB Output ports.

On Top:

On top of the power bank is where there’s a power button and an LCD screen that shows the power capacity in a percentage manner, as well as the Voltage that’s being outputted when it comes to charging a Laptop.

Charging automatically starts when you plug a device in either of the USB ports or the DC Output port. You can change the Voltage amount that’s to be outputted when charging a Laptop by holding down the power button and then tapping the power button to select Voltage options of 9V/12V/16V/19V/20V.

Build

Structure and Material:

The entire power bank is made of plastic but it’s still built very well. A solid enough build quality that is going to be useful for everyday use but it’s best to not drop the power bank because it doesn’t have any reinforcements that are able to absorb shock damage in the event of a fall.

Tech:

On the tech side, this high capacity power bank doesn’t do anything too special other than making use of safety tech to keep you and your devices safe even when you’re charging 3 devices at once.

Reliability

This high capacity power bank is going to be perfect if you plan on charging your laptop with it. However, if you only plan on charging your smartphone or tablet wth the device, then you’re only using half of what its main features are.

It’s a very portable power bank that’s able to charge laptops, and that’s how it’ll be most reliable, by charging laptops.

Summary:

Power:

There’s enough power capacity to charge smartphones, tablets, and laptops multiple times. There are two USB ports, and even though it’s awesome that you can charge 2 USB devices at once, one USB port has a slow charging speed of 5V/1.0A. You can charge a laptop using the DC Output port, and that can result in being able to charge 3 devices at once.

Design:

It’s large and heavy, but that doesn’t mean it’s not portable. This high capacity power bank can be taken anywhere, it’s just that you’re going to have to set it down when you use it.

Build:

Nothing special about the build quality, but the power bank does hold its own and it’s quite sturdy which is great if you’re using it daily.

Reliability:

Even though it has a very high power capacity and 3 ways to charge devices; using the DC Output to charge laptops is its signature features that are going to give you optimal reliability.

Review: ALLPowers 30,000mAh Power Bank

Most of the time, when we think of high capacity power banks, the range of power is usually 15,000mAh to 20,000mAh. That’s an understandable point of view because that amount of power capacity can charge lots of devices many times over. With that said, power banks come in even larger power capacities that go in ranges that are able to last for a very long time. In addition to these colossal power capacities, there are also lots of charging ports and recharging ports.

In this case, we’re reviewing this ALLPOWER 30,000mAh power bank. That’s a lot of power, and with it, comes the responsibility of being able to utilize it correctly. Let’s see what it has.

Power

Power Capacity:

How Much Power You’ll be Getting

The power capacity of this ALLPowers power bank starts at 30,000mAh, with that said, the power capacity that you’re actually going to be receiving is going to be lower. Although that’s nothing to be disappointed about, but we’ll get to that in a moment. The conversion rate of this ALLPowers portable charger is quite good because most of the time it’s going to be average; through inefficiencies of converting power within the batteries and the power going through the charging cable. With that said, you’re going to be averaging a conversion rate of about 70% and that’s going to result in an Output power capacity of 21,000mAh that you can actually use.

As we said before, the power capacity you’ll be able to use is going to be lower than the initial and one of the main reason this isn’t too much of a bad thing is because there’s 21,000mAh of power to use. That’s a lot of power no matter how you look at it.

Charging Smartphones with the ALLPowers 30,000mAh Power Bank

It’s with this power capacity that you’ll be able to charge most smartphones 7 times or more. This is going to be true even for high capacity smartphones like the Samsung Galaxy S7 with its 3,000mAh battery capacity as it’s going to be able to charge to its full power about 7.5 times. Smartphones that have lower capacities than a Galaxy S7 are going to be able to charge a lot more times, chances are that you possibly own one too.

Charging Mini Tablets

As for charging tablets, the experience is basically the same as charging smartphones but with tablets thrown into the mix. If you’re going to charge Mini tablets like an iPad Mini 2 or 4 series then that’s going to result in about 3.5 full charges.

Charging another mini tablet like a Galaxy Tab with its 4,000mAh is going to be able to charge to full power about 5 times. So even for tablets, devices that have very high battery capacities, this power bank has the ability to cut right through them.

Charging Full-Sized Tablets

Lastly, if you’re wanting to charge a very high capacity device like a Full-Sized iPad 12-Inch that has a battery capacity of 10,000mAh then it’s going to be able to charge to its full power 2 times. This can’t be said about too many power banks on the market.

Output Charging:

There are 3 charging ports on this ALLPower 30,000mAh power bank, but more important than quantity of ports are the quality of the charging ports.

Each of the three USB Output ports is able to output 5V/2.4A and the Max Output of the power bank is 4A. Not too bad.

When it comes to the individual charging ports, a charging speed of 2.4A is a Max Standard charging speed that’s able to charge most devices at their max charging speed. This goes for most smartphones, although it’s not going to be able to charge Quick Charge compatible smartphones at their max charging speeds because this power bank does not have Quick Charge. With that said, it will charge tablets at their max charging speeds.

If you’re using all 3 charging ports and the Max Output of 4 Amps is being reached, then each port will output 5V/1.3A. Not too bad, but that can be quite slow for most modern smartphones as they mostly charge within the 2 Amp range. So if you want to charge the device as fast as possible with the power bank, then it’s best to charge 2 at a time to make sure that you’re not spreading the power too thin.

Input Charging:

A power bank that has a power capacity of 30,000mAh is usually going to take a while to fully recharge, but that shouldn’t be the case with power banks that have a power capacity THIS LARGE. As a result, this power bank uses 2 Micro-USB Input ports, you’re able to recharge it just like 10,000mAh power bank would charge.

Each of the Input ports has a recharge speed of 5V/2.0A, so as long as you’re using a 2 Amp wall charger for each of the ports, then the power bank will be recharged at 4 Amps. This is going to result in a full recharge within 7-8 hours. For 30,000mah, that’s a very fast recharge rate.

Design

Size and Weight:

Of course, when a power bank has a power capacity of 30,000mAh it’s going to be very large and heavy.

This ALLPowers portable charger has a length of 6.9 inches,  a width of 4.3 inches, and a thickness of 0.7 inches. The weight of the power bank is 1.3 pounds. So quite large and heavy. Most of the time this is going to be set down and used.

Functional Components:

Almost all of the functional parts of the power bank are on a single side. On that side is where you’ll find 3 USB Output ports, 2 Micro-USB Input ports, and a power button. On top of the power bank is where there are 4 LED Power capacity indicators.

Charging automatically starts when you connect a device into any of the 3 charging ports, so the power button is mainly used to check the power capacity that’s left.

Build

Structure and Material:

The entire power bank is made of plastic. It has a good solid build, however, it’s not recommended that you drop it because there’s nothing to absorb shock when it does fall.

Tech:

On the tech side, the power bank makes use of multiple safety protections like Surge and Short-Circuit protection to make sure nothing goes wrong eve when you’re charging 3 devices at once.

Reliability

For the most part, this ALLPower 30,000mAh is going to serve you well.

It has a power capacity that’s going to charge nearly every USB chargeable device multiple times. Even with the Output power capacity that you’ll be able to use, it still holds up with the ability to charge smartphones and tablets multiple times over; which can make it last for a long time.

There are 3 charging ports to charge 3 devices at the same time, and you can rely on this power bank for delivering quite the fast charging speeds. With that said, it’s best to charge 2 devices at most if you want to charge the fastest. With all that said, it’s important to remember that a 30,000mAh power bank is going to be very large and heavy, as this power bank is.

Summary:

Power:

The power capacity is enough to charge lots of devices multiple times over and if you’re charging only smartphones with the power bank, then it can very well last for a week or even more. The 3 charging ports are very useful, but it’s best to use 2 charging ports at the same time to make most of the charging speed; since the Max Output of the power bank isn’t too high at 4A.

Design:

It’s large and heavy. Not meant to be held in the hands. So you’re going to have to set it down most of the time. It’s at least easy to use with almost all of the functional parts being on a single side.

Build:

It doesn’t have the strongest build, but it does have a solid one. Just don’t go dropping it on hard flooring.

Reliability:

If you’re searching for a power bank that has a very high power capacity, and we mean really high along with lots of charging ports, then this ALLPowers power bank may be just what you’re looking for. Although it’s not the best for portability.

Specs of the ALLPowers 30,000mAh Power Bank:

  • Capacity:            Advertised: 30,000mAh            Real Capacity: 17,000mAh
  • Output:   Per Port: 5V/2.4A       Max Output: 4 Amps
  • Input:      Both Micro-USB Input Ports: 5V/2.0A       Max Input: 4 Amps
  • LED Power Indicators: 4 LED Dotted Power Capacity Indicators
  • Size: 6.9 x 4.3 x 0.7 inches
  • Weight: 1.3 Pounds

Conclusion:

Most high capacity power banks are going to be large and bulky, and that’s the cost of having multiple charging ports and a very useful capacity.

That’s really the only gripe about this power bank, though. It has as power capacity that can charge most devices multiple times over and give you the ability to charge 3 devices at once.

Review: CanBor 22,000mAh Power Bank

Power banks that have very large power capacities also tend to have multiple charging ports and even though these kinds of portable chargers are quite large; they’re very helpful for providing multiple charges. With that said, as alluring as multiple charging ports are, what really matters is what those charging ports are capable of. This is because if a power bank has 3 charging ports and each of those 3 ports can only offer 5V/1.0A charging speeds, then that’s bad. What’s needed is a high charging speed for the individual charging ports and a high enough Max Output.

At Charger Harbor, we’ve reviewed quite a lot of high capacity power banks that have many charging ports and the ones that provide the most value are the ones with not only lots of power but also speed. This CanBor 22,000mAh power bank has a pretty good capacity but let’s see what it has to offer when it boasts 3 charging ports.

Power

Power Capacity:

The starting power capacity of the CanBor power bank is 22,000mAh but just like all power banks, when charging is happening there’s a conversion of power from the power bank to the device that you’re charging. The inefficiencies during charging happens in the batteries of the power bank and through the charging cable. With that said, the more devices that you charge at the same time, then there’s more likely to be more inefficiencies, as a result, more power is going to be lost.

How Much you’ll actually be Receiving

With that said, this CanBor power bank has an average conversion rating of about 70% and that’s going to result in you having 15,000mAh of power capacity that you can actually use. Even though there’s about 7,000mAh of power capacity missing, the 15,000mAh of power that’s remaining is still a lot of power.

Power Capacity for Smartphones

This is because you can use it to charge smartphones that have very large battery capacities multiple times. Examples of smartphones with large batteries are:

iPhone 6s Plus – 2,915mAh power capacity

Galaxy S7 – 3,000mAh Power Capacity

Galaxy Note 5 – 3,000mAh Power Capacity

iPhone 7 Plus – 2,900mAh Power Capacity

All of those smartphones are some of the most used on the market, and you’ll be able to charge all of them about 5 full times to their full power, with the CanBor power bank. In addition, if you have a smartphone that has a lower battery capacity, which is very likely, then you’re going to be able to get a lot more full charges.

Power Capacity for Tablets

Of course, one of the main reasons that some people purchase this power bank is for charging their larger devices like tablets. For Mini tablets like the iPad Mini 2 or 4, you’ll be able to get 2 full charges. If you’re wanting to charge a Galaxy Tab with most of them having a power capacity of 4,000mAh, then you can charge one about 3 times to its full power.

Charging a Full Sized 12-Inch iPad can also be done because you can charge it to its full power; there will also be more power capacity even after its full charge.

Output Charging:

The main thing is to not be misled by the many charging ports that a power bank has, and thankfully, CanBor did a pretty good job with the charging side of this power bank.

Max Output and USB Port Speeds

This is because each of the 3 charging ports can Output 5V/2.1A charging speed and the Max Output of the power bank is 4.2A. So you can use the full power of two charging ports at the same time. If you’re charging 3 devices at the same time, with the Max Output of 4.2A being used, then each charging port will be able to Output 1.4A.

A charging speed of 2.1A is quite good and most devices are going to be able to charge at their max charging speed, however, this power bank does not feature Quick Charge tech and so the devices that are compatible with Quick Charge aren’t to be able to charge at their max charging speed.

The CanBor power bank does a good enough job at providing a charging speed that’s going to provide a noticeable result. If you want the best charging speed, then it’s best to charge 2 devices at once if they require fast charging speeds.

Input Charging:

The CanBor power bank is able to recharge at a possible max charging speed of 5V/3.0A and this is quite uncommon but VERY useful among power banks that have high power capacities.

With that said, if you want to charge this CanBor power bank at its max charging speed, then you’re going to need a Quick Charge wall charger and that’s going to result in a recharge time of 7-8 hours.

If you’re using a 2 Amp wall charger then that’s going to result in a recharge time of 9-10 hours.

Design

Size and Weight:

With its high power capacity, comes the size and weight to match. It might be larger than most power bank that you know of but it’s manageable to hold, but the main issue is that it’s quite heavy.

 

It has a length of 6.4 inches, a width fo 3.1 inches, and a thickness of 0.7 inches. It weighs 1 pound. So it can fit into a single hand, but if you’re planning is to walk around with the power bank in hand, then that can be uncomfortable for a long duration.

Functional Components:

 

On the short side of the power bank is where there’s the 3 USB Output charging ports, and the Micro-USB Input port. On the long side is where there’s a power button. On top is 4 Blue LED power capacity indicators.

The Canbor power bank has quite an unusual shape in comparison to power banks that have a more symmetrical, but the curvy design does hold a certain aesthetic that makes it cool to look at. Charging automatically starts when you connect a device into any of the 3 charging ports, and that leaves the power button most as a way to check the power capacity.

Build

Structure and Material:

The entirety of the power bank is made of plastic, but it’s still built solidly. A part of the power bank has a rough side and that makes it easy to hold and it’s resistant to scratches. Although, we don’t really understand the point of making a specific point on the power bank scratch resistant.

Tech:

It makes use of the necessary safety tech feature with the ability to automatically shut itself off when/if anything goes wrong. In addition is has the CE, FCC and RoHS certifications.

Reliability

If you’re searching for a power bank that has a high power capacity and can also charge multiple devices at the same time, the this CanBor portable charger may be just what you need.

The size can be troublesome along with the heavy weight, but other power banks with just as much power capacity are going to be just as large.

Summary:

Power:

The Output power capacity is going to give you lots of full charges for plenty of devices. This goes for small devices like smartphones and also larger devices with bigger batteries like tablets.

Along with the 3 charging ports comes a good charging speed of 2.1A for individual ports and a Max Output of 4.2A.

Design:

It’s quite large but what makes it difficult to carry is the 1 pound weight.

Build:

It has a good build regardless if it’s made of plastic.

Reliability:

This power bank has a power capacity that’s going to last long and charging speed that is going to provide results.

Specs of the CanBor 22,000mAh Power Bank:

  • Capacity:            Advertised: 22,000mAh            Real Capacity: 15,000mAh
  • Output:   Per Port: 5V/2.1A       Max Output: 4.2 Amps
  • Input:      5V/3.0A Via a Micro-USB Input Port
  • LED Power Indicators: 4 LED Dotted Power Capacity Indicators
  • Size: 6.4 x 3.1 x 0.7 inches
  • Weight: 1 Pound

Conclusion:

It can be very easy to be fooled by a power bank that has lots of charging ports and a high power capacity. The charging speeds might be poor and the power capacity might go through a very poor conversion.

That’s thankfully not the case here because the CanBor power bank delivers with its charging speeds and power capacity. The size and weight of the charger are to be expected with its power capacity.

Review: Tiergrade 22,000mAh Power Bank

Power banks that have high power capacities will inevitably have many charging ports because when there’s a high power capacity, there’s more to be done with that power.

Multiple charging is great for charging lots of devices at once and this is especially true if you’re using a power bank because you’re able to charge a device wherever you are, rather than being limited by a USB wall charger. However, what’s more, important than having lots of charging ports is what are those charging ports capable of. Some power banks have lots fo charging ports and yet the charging speeds aren’t that good; so charging multiple devices at once isn’t the best course of action.

Let’s see if this TierGrade 22,000mAh power bank is able to use its ports in a smart way.

Power

Power Capacity:

The power capacity of the Tiergrade power bank starts at 22,000mAh and it goes through a regular conversion rate that a 3-port power bank usually goes through. Since there’s energy converting with the battery inside the power bank and then through the charging cable; you also have to consider that when you’re charging multiple devices at once, which increases Amperage Output, that’s a cause of power being lost during charging too. As a result, there’s going to be an average conversion rate of 70% and most of the time that’s going to leave you with an Output power capacity of 15,000mAh.

Charging Smartphones

Even with an average conversion rate, the TierGrade power bank does a great job at providing lots of power to smartphones because you’ll be able to charge most smartphones about 4 times or more. Take, for example, charging a Galaxy S7 with the TierGrade with the result in 5 full charges. The same thing goes for another high capacity smartphone like the iPhone 7 Plus that can also charge 5 full times with this power bank. So you’re going to be able to get plenty of more charges if you have a smartphone that has a lower battery capacity than either of those two smartphones we just mentioned.

Charging Mini Tablets

The TierGrade power bank also does a pretty good job at handling to charge Mini iPads because whether you’re charging an iPad Mini 2 or 4 series, they’ll be able to charge about 2.5 times. Charging a Galaxy Tab A is the same say but you’ll fair a bit more at 3 full charges.

Charging Full-Sized Tablets

Lastly, you can even charge a Full-Sized iPad 12-Inch to its full power only once, but even then, the TierGrade power bank will still have some power capacity left over to charge a smartphone to its full power.

Output Charging:

This is where the TierGrade falls short because it means well with its 3 charging ports but the power simply isn’t there.

There’s one charging ports that has a charging speed of 5V/2.4A and the other two charging ports have a charging speed of 5V/1.2A. The Max Output of the power bank is 4.8A.

Just How Good are the Charging Speeds?

If there are two things that the power bank does very well it’s that each charging ports can be used to its full potential and also the max Output of the power bank isn’t limiting.

With that said, the two charging ports that have a charging speed of 5V/1.2A offer slow charging and this is true for when you’re either charging a smartphone or tablets. It would have actually been better for the TierGrade power bank to just use 2 charging ports and have them both have an Output of 5V/2.4A. This way you could charge 2 Tablets at the same time and have them charge at their max charging speed.

How You Should Use the Ports

Although, in this case, you want to use the port with 2.4A first because it’ll charge your device the fastest and the other two charging ports should be used with the knowledge that they’re going to be charged slower than usual. With that said, you’re at least able to take advantage of all the charging power without any compromises because of the if you’re charging 3 devices at once, the charging ports speeds of 2.4+1.2+1.2 are equal to the Max Output of 4.8A.

Input Charging:

On the recharge side, the TierGrade power bank is recharged through a Micro-USB Input port with a recharge speed of 5V/2.0A. The TierGrade power bank actually comes with a USB wall charger that a charging speed of 5V/2.1A throughout each of its charging ports; so you’ll be able to recharge the power bank at its max charging speed with the wall charger that it comes with.

Design

Size and Weight:

Along with the high power capacity, the power bank is quite large and heavy.

It has a length of 6.5 inches, a width of 3 inches, and a thickness of 0.8 inches. The weight of the power bank is 15.2 ounces. So it’s still portable but it’s still large and heavy enough that it won’t be very comfortable to hold in a single hand for too long.

Functional Components:

The 3 charging ports are on the short side of the power bank. On top is where there is the power button and the 4 Orange LED power capacity indicators. On the long side of the power bank is where you’ll find the Micro-USB Input port.

Charging automatically starts and that means you’re mostly going to be using the power button to check the power capacity.

Build

Structure and Material:

The TierGrade power bank is made of plastic but it has a certain sturdiness to it that makes it great to use every day. However, it’s important to be cautious when you have the power bank over hard flooring because it might not be able to take a drop like that.

Tech:

On the tech side, the TierGrade power bank has the basic safety feature to keep you and your devices safe during charging.

Reliability

Here’s the thing, there are better power banks that have nearly as much power capacities. By that we mean they do the charging portion better than the TierGrade power bank because instead of spreading charging throughout 3 charging ports, it’s best to just use two charging ports and have of them be powerful.

In the TierGrade’s case, two charging ports that have 5V/1.2A charging speeds are spread too thinly and are basically a 2.4A port that has been split into two. So you can’t charge two iPads at their max charging speeds.

Summary:

Power:

The power capacity even when it goes through its conversion is still enough to charge most smartphones and Mini tablets multiple times. It’s a good power bank to take on long road trips, or for when you’re traveling. There should really only be 2 charging ports so more power is available to use from each.

Design:

It’s large and heavy, but that’s to be expected when you have something with its power capacity.

Build:

It has a sturdy built quality but don’t go dropping it on a hard floor because it doesn’t have any build qualities that protect it from shock damage in the event of a fall.

Reliability:

The TierGrade power bank has a lot of good quality with its high power capacity and 3 charging ports. With that said, the use of 2 charging ports, with them both having a 5V/2.4A charging speed would have been more reliable to use and provide more quality.

Specs of the Tiergrade 22,000mAh Power Bank:

  • Capacity:            Advertised: 22,000mAh           Real Capacity: 15,000mAh
  • Output:

Port 1: 5V/2.4A

  • LED Power Indicators: 4 LED Dotted Power Capacity Indicators
  • Size: 6.5 x 3 x 0.8 inches
  • Weight: 15.2 Ounces

Conclusion:

We think that the TierGrade power bank does a spectacular job at being a high power capacity power bank. It’s the use of 3 charging ports that is more of a glamor status than a useful feature.

Review: Crave PowerPack 50,000mAh

Power banks that have very high power capacities are able to provide more than just a power capacity that can charge many devices multiple times over. These kinds of power banks are also able to charge many devices at the same time and they can also charge larger devices like laptops. However, as amazing as these kinds of portable chargers are, the “Portable” part of them isn’t exactly as portable as the word defines. Since they have larger power capacities and size capabilities, the equivalent exchange with all that power is that you get something that is large and heavy.

With that said, being large and heavy isn’t really that bad when you have so much power that is utilized in such a great way. This Crave 50,000mAh power bank is able to achieve just that with its power, but the charging portion of the power bank is quite weak. Let’s take a closer look in this Charger Harbor Review.

Power

Power Capacity:

Much like any other power banks on the market no matter how small or large they are, the power capacity that a power bank starts with isn’t what you’re really going to receive. This is because during charging the power has to go through a conversion process through the batteries, circuitry, and then through the charging cable to your device.

In this case, the Crave power bank has an average conversion rate, and this mostly attributed to its capability of Outputting 5 Amps all at once. As a result, you’re most likely going to be able to charge 3 devices at once with the power bank, which is going to give you a 70% conversion rate; this means that you’ll be able to use about 35,000mAh of usable power. And that’s still a lot of power to use.

The Crave power bank is absolutely going to dominate when it comes to charging smartphones because you’ll be able to charge smartphones like the iPhone 6s Plus that has 2,750mAh battery capacity about 13 times to full power; you can charge the new iPhone 7 18 times to its full power. Even charging smartphones that are higher up on the battery spectrum such as a Samsung Galaxy S7 with this power bank, you’ll be able to get 11 full charges.

With all that said, just remember that we’re measuring full charges by charge a certain device alone with the Crave 50,000mAh power bank, and no other devices charging at the same time.

Output Charging:

There are quite a lot of options to charge using the Crave power bank.

USB Charging:

There are 4 USB charging ports; two of the USB charging ports have a charging speed of 5V/2.1A and the other 2 charging ports have a charging speed of 5V/1.0A.

5V/2.1A Charging Ports:

The two charging ports that have a charging speed of 2.1 Amps are the two that you should be using no matter what USB charging device you’re using. This is because most devices will be able to charge at their fast charging speed with both of these ports; this goes for most smartphones, but this power bank does not feature Quick Charge and as a result, they won’t be able to charge at their max charging speed.

However, these two charging ports are very good for charging tablets as well because you’ll be able to charge most tablets at or at least near their max charging speeds.

5V/1.0A Charging Ports:

Both of these charging ports are the ones that are best to avoid because the charging speeds are slow. So the only reason that you’re going to use these charging ports is when you’re charging more than 2 USB charging devices and are forced into using these ports.

DC Charging:

There is 2 DC Output charging ports that are useful for larger devices like Laptops and Digital Camera.

20V/3A DC Output Port:

This DC charging ports is most useful for charging devices like Laptops and it’ll actually be able to charge most Laptops at their max charging speeds. With that said, the power bank cannot charge MacBooks because it does meet the charging power that MacBook use to charge.

12V/2.5A Charging Port:

This DC port Output lower power than the other charging port but it’s still very useful for charging lower power devices.

Overall Output Charging:

So there is actually some bad news that goes with this highly capable power bank, and that’s because the charger is only able to Output 5 Amps of power at once. Once the power bank is Outputting over 5 Amps at once, then it will turn off. This is a safety feature to make sure that the power bank doesn’t overheat and damage itself. Even so, that’s quite a low Max Output that is only going to allow you to charge 3 devices at once at most.

Input Charging:

For a power bank that a power capacity of 50,000mAh, the charging speed is really good. It’s recharged through a DC Input port that is able to recharge the power bank at 16.8V/2.5A; so the Crave portable charger is able to fully recharge within 7-8 hours. That’s not bad at all considering the power capacity of the power bank can last for weeks and all you have to do is recharge it for a couple of hours.

Design

Size and Weight:

With it having such a large power capacity, the size of the power bank is going to match it too. This is because it’s a large and heavy power bank that’s not meant to be held.

It has a length of 8 inches, a width of 6 inches and the thickness is 2 inches. The weight of the power bank is 1 pound. So it might be large and heavy, but that doesn’t mean that the Crave power bank is not portable. After all, it’s still a portable power. With that said, it’s still good to take when you’re at work, or at the library because you can just set it down and charge your laptop and smartphone without being next to a Wall Outlet.

Also, it can be taken for camping trips or a hike into the outdoors and even though it’s heavy, placing it into your backpack will improve portability. With something that has so much power capacity, it’s very helpful to have long lasting power.

Functional Components:

All of the functional parts of the power bank are on a single side of the charger.

On the side is where you’ll find:

  • DC Input port
  • 4 LED power capacity indicators
  • the power button
  • two DC Output ports
  • 4 USB charging ports

You must press the power button to begin charging from the power bank.

Build

Structure and Material:

The entire Crave power bank is made of plastic but it’s still built very well, with the plastic being used being very thick. However, we recommend not dropping the power bank because it doesn’t have any shock absorbing properties that are going to save it.

Tech:

On the tech side, there’s quite a bit going on with the Crave power bank using a wide range of safety tech features to keep charging safely. One of the most useful ones is the usage of Auto-ShutOff abilities; with the auto-ShutOff, once the Max Output capabilities of the power bank have been reached, then it turns off automatically. This is able to prevent damage to the power bank.

However, we found that it has a low Max Output that could have more potential in terms of getting more out of the power bank.

Reliability

This 50,000mAh Crave power bank is very useful for when you’re either charging USB chargeable devices and Laptops and when you want to charge them LOTS of times over. It’s the power capacity that is the main attraction here because it can last very long and that means you can rely on a single full charge of the power bank for a long while. Also, in addition to the charging ports that allow you to charge many devices at once, including a Laptops, then we think that this power bank has flawless reliability.

With that said, there are still some unreliable traits that it holds. It’s a very large and heavy power bank that isn’t the best to carry around. Also, with its Max Output limit of 5 Amps all at once, the power bank can at most charge 3 devices at once which makes its other charging ports that aren’t be used, irrelevant.

Summary:

Power:

It has a very large power capacity and many charging ports. The power capacity is high enough that you can charge tablets, and smartphones lots of times over. You can get about 2 full charges for most smartphones. There are 4 USB charging ports. Although the powering capabilities seem flawless, the power bank can only Output 5 Amps at once.

Design:

It’s large and heavy by nature because of its high power capacity. All of its usable parts are on a single side and you have to press the power button to begin charging.

Build:

Not the strongest structure but it’s still quite sturdy. Just don’t go dropping the power bank because that may very well damage it.

Reliability:

With its high power capacity and lots of charging options, for the most part, this Crave portable charger is very reliable. However, the Low Max Output of power can prove to be limited and so can the size and weight of it.

Specs of the Crave PowerPack 50,000mAh:

  • Capacity:            Advertised: 50,000mAh            Real Capacity: 35,000mAh

  • Weight: 1 Pound

Conclusion:

The Crave 50,000mAh power bank is perfect when you’re going to be away from a stable source of power for a while because it has the power that can last for days, weeks and possibly a month. Even though it has 4 USB charging ports, what really takes the cake is the usage of DC Output ports that are able to charge Laptops. Even with all of its grandeur it still has its setbacks with not having a higher enough Max Output of power and it’s important to remember along with its high power capacity, also comes its large size and heavy weight.

Review: MAXOAK 50,000mAh Portable Charger

Basically, any more power bank on the market is going to be able to charge your smartphone, whether you have an Android or iPhone, all power banks are compatible to charge them. Then after you get past that, there are the rest of the things that a power bank features that you have to look at features such as the power capacity, charging speed or size of the charger too.

Some power banks are larger than others because they have very large power capacities and they also have many different charging capabilities. Just like this MAXOAK power bank that has a 50,000mAh power capacity and 6 ways to charge your devices. The power capacity alone is staggering but the 6 charging ways are really what takes the trophy.

Power

Power Capacity:

The starting power capacity of his MAXOAK charger is 50,000mAh and there’s still a lot of power even when the power capacity goes through a conversion. Just how much power capacity is lost during charging? Well, the MAXOAK has an average conversion of 70% and that’s going to leave you with 35,000mAh of useable power. This is mainly because there’s going to be a lot of things charging at once when you use the power, the power banks uses Lithium Polymer batteries, and of course, there’s power lost through charging cables; and since you’re going to be charging many devices at once, there’s going to be power lost throughout each charging cable.

How does the MAXOAK 50,000mAh Charge Smartphones

With all that said, we don’t find this to be a hindrance because the power bank still has a lot of power capacity to actually use. It’s going to burn right through charging smartphones because you’ll be able to charge even larger battery capacity smartphones multiple times over; like the iPhone 6 Plus that has a capacity of 2,915mAh which you’ll be able to charge 11 full times and the same goes for a Galaxy S6 that will charge also charge 11 times too.

So if you’re charging solely smartphones with the power bank, it could last on a single charge from anywhere for about a week or even a month if you’re occasionally using it.

How does the MAXOAK 50,000mAh Charge Tablets

It’s also a good power bank for charging tablets and this time this isn’t just true for charging Mini tablets, but let’s go over those first anyways. If you’re charging smaller tablets like the Samsung Galaxy Tab, then the power bank will be able to charge them about 7 times to full power. Or if you’re charging an iPad Mini 2 or iPad Mini 4 then they’ll be able to get 5-6 full charges.

Moving onto the larger, more colossal USB charging devices, the Full-Sized iPad 12-inch tablet that has a power capacity of 10,000mAh is going to be able to charge 3 times to its full power capacity; considering that it’s a full-sized tablet, the MAXOAK power banks hits it right out of the ballpark with multiple full charges.

Output Charging:

Even though there’s a lot going on with the charging side, it’s easy to make sense of and this is the second strongest point of the power bank after the power capacity being the first.

Charging with the USB Charging Ports

There are 4 USB charging Ports. Two of the USB ports have a charging speed of 5V/2.1A and the other 2 charging ports have a charging speed of 5V/1.0A.

5V/2.1A charging Ports:

Both of these charging ports are the ones that should be your first choice when using any of the 4 charging ports because they offer the faster-charging speed. They’re able to charge most smartphones at their max charging speed, however, the power bank does not feature Quick Charge and therefore, Quick Charge smartphones will not be able to charge at their max charging speeds.

With that said, both these ports are still powerful and they’re perfect to use with tablets too because they can charge some tablets at their max charging speeds and the charging speed comes close to charging iPads at their max charging speed of 5V/2.4A.

5V/1.0A charging Ports:

You should only be using these 2 charging ports if you’re already using the two 2.1A charging ports, this is because both this only offer 1 Amp charging speeds and that’s slow charging for most smartphones and tablets.

Although, overall, you’re able to charge 4 USB charging devices at the same time and that’s amazing.

Charging with the DC Output Ports

There are 2 DC Output charging ports. One provides more power than the other but either way, they’re able to charge compatible laptops or digital cameras. Also, it’s important to know that you can use all 4 of the USB charging ports and 1 DC Output port all the same time.

DC 20V/3A Output:

This DC port is able to charge most Laptops and if you check out the Amazon page of the MAXOAK power bank, then you can see that it actually comes with 11 different kinds of connectors for many different Laptops. With that said, the power bank cannot charge MacBooks.

Also, before purchasing, check the charging power that is needed to charge your Laptop which can most likely be found under the Laptop or on the power brick that it uses for charging.

DC 12V/2.5A Output:

The other DC Output port has a lower charging speed and MAXOAK has said that this DC port is most useful for charging Digital cameras; even though it can be used for that purpose, it can also be used to charge Laptops as well and any other devices that have charging needs that fit its Output.

Input Charging:

It uses a DC Input to recharge itself and for a 50,000mAh power bank, it recharges very quickly because the Home charger that the power bank comes with is able to recharge the MAXOAK portable charger at 16.8V/2.5A. As a result, the power bank is able to recharge to full power within 6-8 hours.

Design

Size and Weight:

Portability is not the strong point of the MAXOAK power bank because it’s large and very heavy. Yes, it’s portable but in a more eventful manner of taking this on a road trip, for camping or taking to the library because you can freely sit anywhere you want without having to be next to an Outlet.

It has a length of 8.1 inches, a width of 5.3 inches and the thickness is 1.3 inches. The weight of the power bank is 2.7 pounds. So for the most part, this going to be set down, and it’s going to be placed into a bag for when you’re taking it places; luckily it does come with a container/bag to place the power bank in.

Functional Components:

All of the functional parts of the high capacity power bank are on a single side and we mean everything. This includes the 4 USB charging ports, the 2 DC Output ports, the power button, 4 LED power capacity indicators and the Input port. Charging does not start automatically, so you must press the power button to begin charging.

Build

Structure and Material:

The MAXOAK power bank is very sturdy, it can withstand shortfalls onto carpeted flooring but we don’t think it can withstand high falls onto hard flooring. So it’s perfect to be used every day, to have it with you on travels and so on.

Tech:

Since you can potentially charge 5 devices at the same time, the MAXOAK power bank has a 6 Tech Safety system that is able to keep you and your devices safe during charging. One of the most useful ones is Over-Current protection, which is able to shut the power bank off automatically if the power bank is Outputting too much power than it can handle; this is able to prevent damage to the power bank and stop a potential fire.

Reliability

If you know what you’re getting with the large size and weight, then the MAXOAK power bank is a very reliable portable charger. You can charge 2 smartphones or 2 tablets at the same time or possibly 4 smartphones at the same time if you wanted to, and to put it basically, you can charge a lot of devices on the USB charging end.

Another major reliable factor is that you can charge Laptops as well and that can be useful for when your Laptop is lower on power and you’re nowhere near a Wall Outlet. Of course, there’s the power capacity that can last for days and even weeks depending on how your use the power bank.

Summary:

Power:

It has a very high power capacity that can charge lots of devices many times over and this isn’t just for smartphones, it’s true for Mini tablets as well as Full-Sized tablets and Laptops too. You can charge 5 devices at the same time with 4 of them being USB charging devices and 1 DC Output device like a Laptop.

Design:

It’s a large and heavy power bank and that’s normal because of the high power capacity. With that said, it’s easy to use and you can still take it with you on your travels; it’s just that you’re moving around more weight and mass

Build:

Not a rugged power bank but it holds its own with a strong build. The tech is on par with what the power bank offers with it being able to automatically shut off if things are becoming too heated.

Reliability:

It’s the perfect kind of power bank for traveling and any time when you won’t have a stable source of power. For two main reasons.

It has a humongous power capacity and because it can charge lots of devices at once.

It’s large size and heavy weight aside, the MAXOAK is a strong companion to take with you to places that you doubt that you’ll have a stable source of power; not only for your smartphones or tablets but also for your Laptop. Stay powerful.

Review: MAXOAK 36,000mAh USB-C Power Bank

Most of the time when we think of high capacity power banks, we usually think of portable chargers that have power capacities of 20,000mAh and lots of charging ports. Then there are cases when power banks go even beyond that, in terms of power capacity and with their amount of charging ports. They not only have the usual USB charging ports, but they are also able to power bigger and more powerful devices. Although, it’s important to keep in mind that even though power banks like these are very strong, they’re also very big.

This is the MAXOAK 36,000mAh power bank that has a lot of power capacity and charging power as well.

Power

Power Capacity:

The power capacity of the MAXOAK 36,000mAh power bank starts at 36,000mAh and the conversion rate of the power capacity is very average because the power capacity has a 70% conversion rate during charging. With that said, that means you’re going to actually receive about 25,500mAh of useful power capacity that you can actually charge your devices with.

So yeah, we know that you’re missing a 10,000mAh of power, and that’s a lot that could have been used to charge a device multiple times over; but just realize that 25,500mAh of power is still enough to charge devices multiple times over no matter how large their battery capacities are.

Power Capacity for charging smartphones

This is because devices like smartphones are going to be able to charge into the double digits with something like an iPhone 6s being able to recharge to full power about 15 times over. Even charging higher power capacities smartphones like the Galaxy S6 will result in about 9 full charges.

Power Capacity for charging tablets

It’ll also be able to charge tablets with no problems because you’ll be able to charge a Mini tablet like the iPad Mini 4 about 5 times over, and if you’re charging full-sized tablets like an iPad Pro that’s 12 inches big then you’ll fair about 2.5 charges.

Power Capacity for charging Laptops

Then the capabilities of the power capacity are maxed when you bring the charging power to laptops because the MAXOAK power bank is able to charge MacBooks like the 12-inch (Type-C) one about 2.5 times and other old models like the MacBook Air 11-Inch 2.5 times as well.

As you can tell, even though the usable power capacity of the power bank is quite a lot lower than the initial one, it’s still able to charge many devices many times around. This is the perfect power bank to take with you on long travels like road trips or possibly when you’re out camping because it can literally last for days before needing a recharge.

Output Charging:

The MAXOAK is very powerful and we can’t find very many flaws when it comes to its charging power and capabilities of charging a wide range of devices all at once.

2 USB Charging Output Ports:

There is 2 regular USB Output charging ports on the power bank and these are useful for charging your standard USB charging devices like your smartphones and tablets. The best part is that they’re able to charge at quite fast charging speeds, with each one at 5V/2.1A. That’s just shy of a standard max speed at 2.4 Amps.

As a result, most of the smartphones that you do charge with these charging ports are going to charge at their max charging speeds and tablets like an iPad will charge near their max charging speeds too.

However, the USB ports do not feature Quick Charge and won’t charge your Quick Charge compatible smartphones at their max charging speeds. With that said, if you have a USB-C compatible smartphone, then you’re in luck because the power bank has a USB-C charging port that you can use to charge USB-C compatible smartphones at their max charging speeds and that’s at least near Quick Charge speeds of charging.

1 DC Output Port:

The DC Output port is able to output 16.8V/3.5A. So if you have a laptop that fits within that range power then this power bank can charge such laptops. MAXOAK does mention that it cannot charge 20V/85W laptops, so just keep that in mind.

Basically, their main charging devices for the DC port is for Macbooks and if you think that you can charge your Non-Macbook laptop with the DC port then just double check the powering requirements to make sure that it can indeed charge it.

1 USB Type-C Output Port:

The USB-C charging port is going to be very useful for charging newer models of the MacBook 12-Inch and the smartphones that are compatible with USB-C like the Nexus 5X. Nexus 6P or Google Pixel smartphones from Google. Charging power for the port ranges at 5/9/12/3.0A.

Just remember that in order to use the USB-C charging port you need to use a USB-C to USB-C charging cable.

Input Charging:

Despite having a very large power capacity the MAXOAK power bank uses a DC Input port to charge and comes with a charger that you connect to an AC Outlet to recharge the power bank. The power bank recharges at 12.6V/2.5A and that result in the power bank being able to recharge to its full power within 5-8 hours.

Design

Size and Weight:

Of course, with the very large power capacity and numerous way to charge, the power bank is very large and also very heavy.

It has a length of 7.7 inches, a width of 5.3 inches and a thickness of 1 inch. The weight of the power bank is 1.1 pounds. As a result, even though it very large, you can still take it with you on travels, it’s just that you’re not going to hold the power bank very much at all.

Functional Components:

It’s very used to use because all of the functional parts of the power bank are on a single side.

Everything thing is on a short-side of the power bank with the power button, 4 White LED power capacity indicators, the DC Input, the DC Output, the USB-C charging port and 2 USB charging ports. Surprisingly charging automatically starts no matter what charging options you’re using the MAXOAK and charging stops when there aren’t any devices charging on it.

As a result, the power button is mainly for checking the power capacity.

Build

Structure and Material:

It has a strong enough build for something that is as large as this.

The large center piece of the power bank is made of Aluminum and the siding of the charger are made of plastic. Even though it has a solid build, dropping it can result in damage because there isn’t many safety builds to protect from shock.

Tech:

On the tech side, the power bank does make use of lots of safety tech feature and that is absolutely vital for something that has a large power capacity as this and charging power. It also has lots of certifications like the CE, FCC, and UL certifications.

Reliability

The MAXOAK power bank is a very reliable partner of power because it has the power capacity to last for days, not only that, the power capacity is able to charge small or very large device multiple times over. Then there’s the charging, that’s able to also charge small devices like smartphones and larger devices like MacBooks at a very efficient charging speed.

The only downside we can tell with the reliability is the size and weight of the power bank being very large and heavy.

Summary:

Power:

Even though the conversion rate of the power bank makes the power capacity fall about 10,000mAh, there’s still enough power to charge your devices numerous times no matter how large or small they are. Charging capabilities are amazing because it accommodates lots of devices from regular USB charging, to DC charging and even USB-C that is useful for MacBooks and smartphones alike.

Design:

It’s large and heavy, so you’re not going to spend a lot of time holding the charger. With that said, it’s at least easy to use because charging automatically starts.

Build:

It’s no rugged power bank but even so, it has a strong build that is perfect for everyday use, just don’t go dropping the charger.

There’s also lots of safety tech features and certifications to ensure that you’re getting reliable and safe charging at all times.

Reliability:

Possibly the most reliable power bank on the market because it can last a long time and can charge lots of devices within the time that it does have a power capacity left to use.

Review: Swees 25,600mAh High Capacity Power Bank

If you’ve read our many other reviews for high capacity portable chargers, then you probably know what to expect from them. High capacity power banks are supposed to use more than average powering capabilities and this goes for the amount of charging ports that they use and the power behind those charging ports as well. Of course, the size of these high capacity devices can’t really be changed because if you want a high power capacity then there either needs to be lots of batteries or larger batteries to provide a large amount of power.

This is the Swees 25,600mAh power bank. It’s available in the UK Amazon market and we’ve gotta say that we’re impressed by what it’s capable of even though it looks rather large.

Power

Power Capacity:

In most cases when a power bank has a large power capacity like this Swees one has an initial power capacity of 25,600mAh, then the power bank will be using lots of charging ports. In this case, this one is using 3 charging ports, each port is able to Output 5V/2.1A and the Max Output of the charger is 4.5A. Also, another thing to take into account is that it uses Lithium Polymer batteries, which is highly understandable because it makes the portable charger more slim and portable.

With all those things, the Output power capacity of the power bank can change quite a lot or little depending on how you’re using it. How for this review, we’re assuming that you’re going to be using 2 charging ports most of the time and using an overall Output power of 4.2 Amps. It’s with this kind of use that’s going to result in the Output power capacity being about 21,000mAh.

Even though the Output power capacity is few thousand down than what you’d normal receive, it’s still a lot of power that can be utilized to charge small and large devices alike. You’ll be able to charge smartphones 5 times or more and this goes even for the larger battery capacity smartphones like the Galaxy S7 and Google Pixel smartphones.

If you’re planning on purchasing this power bank then you’re also probably thinking of charging larger capacity devices like tablets and well you’re in luck because the Swees power bank will be able to charge Mini tablets about 3 times over with a full charge. It can even charge Full-Sized tablets about 1.5 times. For the most part, this power bank is going to be able to last you for days, weeks and maybe even a month if you’re using it scarcely. Reliable and long lasting power right where you need it.

Output Charging:

Immediately after the high power capacity, the charging experience with this portable charger is the best thing, because it has 3 charging ports and each of the charging ports has a pretty fast speed that’ll be able to charge most devices at their max charging speed or near it.

USB Ports:

Each of the USB ports is able to Output 5V/2.1A charging rate, and that’s really close to a Max standard charging speed of 5V/2.4A. It’ll be able to charge Non-Quick Charge and USB-C compatible devices at their max charging speeds; since those kinds of devices that use USB-C and Quick Charge are able to charge their fastest with their respective charging technology, and this power bank does not feature that.

With that said, 2.1 Amps per port is a lot better than just a single amp and along with the Max Output of 4.5A, your experience with charging is going to be near top tier. Mainly because even when you’re charging 3 devices at the same time, and the power bank is being pushed to its charging limits, the charging speed of each of the charging ports is going to be 1.5A. So it’s still above just single amp, and it should be noted that at that point, you should probably only have smartphones charging. Since charging tablets at 1.5A is going to charge them slowly.

For the most part, the charging speeds are good, it’s just that you have to limit what devices you’re charging at certain times. 2 tablets at one time should be the limit to ensure that you’re getting the fastest charging for them.

Input Charging:

Even though the power capacity and Output charging capabilities are amazing, the recharging is highly disappointing because the power bank only uses a single Micro-USB Input port that has a recharge speed of 5V/2.0A. So if you’re using a 2 Amp wall charger, the power bank will be able to recharge fully within 13 hours.

Design

Size and Weight:

It’s surprisingly not that large and you can hold it in a single hand if you wanted to. With that said, it’s the weight that makes this power bank larger than it really is.

It has a length of 5.9 inches, a width of 4.2 inches, and a thickness of 0.6 inches. So it’s small and even quite thin since it uses Polymer batteries. However being thin doesn’t mean much when the power bank weighs 1 pound and that means most of the time you’re going to be setting it down to use it.

Functional Components:

Designed for many other power banks that are easy to use, this one has most of the functional pieces on just a single side. On the short side is where you’ll find the 3 USB Output charging ports, a Micro-USB Input port and 4 Blue LED power capacity indicators. The power button is on the long side of the charger.

Charging automatically starts when you connect a device into a charging port and that leaves the power button with the main functionality of checking the power capacity.

Build

Structure and Material:

The entirety of the portable is made of plastic but the build quality is exceptionally well because all of the pieces are put together perfectly. With that said, you shouldn’t drop it or treat it roughly because the weight of the charger can inflict damage to it since it produces more shock if it drops.

Tech:

With a portable charger that has this many charging ports and a high power capacity as it has, the Swees power bank takes advantage of lots of safety tech to keep the powerful charging experience constant.

Reliability

If you plan on charging multiple devices at the same time and to charge them at fast charging speeds, then this power bank can do that. Sure, the charging speed can wane if you’re pushing it all the way with charging 3 devices at once. However, even when it’s being pushed to its limits, each of the charging ports is able to deliver a charging speed above 1.5A.

The power capacity is plenty even with the Output power capacity being lower than the initial one; which results in the power bank being able to charge most device multiple times over, and this is true even for larger capacity devices like tablets.

Size is manageable but the weight is the part that makes this power bank seem larger than it really is.

Summary:

Power:

The power capacity is enough to quite possibly charge all the mobile devices that you own multiple times. 3 charging ports allow you to not only charge 3 devices at the same time but to also charge them at fast charging speeds. At least for the ones that are standard charging devices.

Design:

It’s small and but heavy, so it’s not the kind of power bank that you carry around with you and charge your devices.

Build:

Structural and Tech build quality is what you’d expect from portable chargers that are this large.

Reliability:

Of course, it’s reliable with its large power capacity, lots of charging options, and fast charging. It’s just a matter of deciding if it’s enough for you.

Specs of the Swees 25,600mAh High Capacity Power Bank:

  • Capacity:            Advertised: 25,600mAh            Real Capacity: 21,000mAh
  • Output:   Per Port: 5V/2.1A       Max Output: 4.5A

  • LED Power Indicators: 4 LED Dotted Power Capacity Indicators
  • Size: 5.9 x 4.2 x 0.6 inches
  • Weight: 1 Pound

Conclusion:

We find that high capacity power banks are the most reliable kind of portable chargers, and yet not many people like to use buy and use them. It’s understandable, though. They’re large and heavy.

However, they almost always excel in their other areas because of their large power capacities that last long, lots of charging ports and they usually have fast charging speeds too.

Review: Anker PowerHouse 120,000mAh Power Bank

There are just a few of these massive behemoths but this Anker PowerHouse is a portable charger that offers charging capabilities that you’ve probably never heard or even experienced before. It basically brings all the facets of many charging electronics together into one mega charger. It has a V12 Outlet, an AC Outlet, a DC Outlet and 4 PowerIQ USB charging ports. When you lay on the 120,000mAh of power capacity, this thing is powerful and it’s going to be useful for many charging needs. Whether it’s for recreational or serious needs.

Power

Power Capacity:

It’s massive, just absolutely massive. The power capacity of the Anker PowerHouse starts with a power capacity of 120,000mAh, and well, that very large power capacity can change very drastically. This is because the PowerHouse has LOTS of ways to charge from and that means that there’s a lot of power conversion happening.

So let’s take a sec to take a look at the ways to charge with this power bank:

  • 4 USB Ports
  • v12 Outlet
  • DC Outlet
  • AC Outlet

Of course, if you’re getting the PowerHouse, then you’re most likely going to be using the more powerful charging options that aren’t the USB charging ports, and that’s going to result in the power capacity going to some changes during conversion. We know that Anker states just how much charges you’ll be able to get from the PowerHouse with certain devices, like powering a Mini Fridge for 7 hours or get 6.5 charges for a Laptop. These are all still near possible.

However, they’re not exactly real life applicable because the PowerHouse will lose quite a lots of its power capacity during charging and powering devices. This can result in an Output power capacity of anywhere from 100,000mAh to even 80,000mAh if the use of the PowerHouse is getting really heated.

What can do you with the power?

So for the most part, you’ll have at least 90,000mAh of Output power capacity that you’ll actually be able to use, and that’s still A LOT of power to use.

As a result, charging small devices like smartphones will be no problem at all as they’ll be able to charge 20 times or more. Charging smartphones like iPhones will provide the best experience since they have the smaller battery capacities. From then on, the PowerHouse’s charging powers are still able to stand true. As you’ll be able to charge laptops and tablets multiple times well. This ultimately comes down do the PowerHouse becoming the one tried and true way to provide reliable power during a power outage or to use it on your camping and hiking trips.

We don’t see much use for the PowerHouse over more traditional portable chargers because otherwise, it would be overkill.

Output Charging:

Let’s go through each of the charging and Powering options that this PowerHouse is able to offer.

4 USB Output Ports:

Let’s start with the basics of power bank charging. There are 4 charging ports and each of the charging ports is able to Output 5V/2.4A. 2.4 Amps is the Max standard charging speed and will be able to charge most smartphones at their max charging speeds; as well as being able to charge tablets like iPads at their max charging speeds as well.

However, the USB ports don’t have Quick Charge, so Quick Charge and USB-C  compatible devices won’t be able to charge at their max charging speeds. Even so, for USB charging, this is great.

In addition, the Max Output of the USB charging ports is 6 Amps. So when you’re pushing the 4 USB ports to their limits, the Max Output of each of the charging ports will be 5V/1.5A. We consider this to be pretty good, and the 4 devices that are charging when charging is at its limits will be charged at a “Okay” rate.

DC Outlet:

The DC Outlet of the PowerHouse is mostly where you’re going to be using for your Laptop charging needs. It has an Output power of 12V/10A, which is enough power to be able to charge most Laptops at their max charging speeds.

V12 Outlet:

The PowerHouse even has a V12 outlet and this mainly means that you can either use any of your V12 compatible devices with it. With that said, we found that using a car charger is what makes the most sense to use with the V12 outlet because it gives you additional charging ports to use.

Take for instance. You can use a Car charger with 4 charging ports and have 4 more charging ports to use with the other 4 Built-In USB charging ports. As a result, you can potentially make this a 8 port power bank! That’s lots of charging power being outputted and the best part is even with 8 devices charging at the same time, this power banks won’t have a problem charging all of them because of its humongous power capacity.

AC Outlet:

One of the most useful parts of the PowerHourse is its AC Outlet, which is basically like a Wall Outlet. The AC Outlet is able to power devices up to 160 Watts. This means that you can power devices like Mini fridges, lamps and basically any other devices that are of the same power range. However, once the PowerHouse detects a draw greater than 160 Watts it will then disengage.

It’s important to remember that even though the Anker PowerHourse is able to power lots of devices, and has a VERY high power capacity, it isn’t exactly a generator. Think of it as an overly powerful power bank with the ability to power small appliances as well.

Input Charging:

It might be hard to believe but the recharging speed of the PowerHouse is actually quite fast because it’s recharged through the DC port that is also used as the Input for recharging. When you use an AC Outlet in your house the PowerHouse is able to recharge at speeds of 16.8V/7.5A and this will result in a full recharge within just 6 hours.

It comes with a AC Adapter to recharge the unit.

Design

Size and Weight:

Of course, it’s large. Very large and heavy at that too. This is what you get when you pack the equivalent of six 20,000mAh power banks into just a single pack, and there’s also the additional charging options that are very powerful.

It has a length of 7.9 inches, a width of 6.5 inches and a thickness of 5.7 inches. We know that it’s ridiculous to even state the size of the power bank, but now you get the idea that it’s large. However, the more important aspect of its design is that it’s really heavy at a weight of 9.3 pounds. So yeah, basically holding this is like holding a dumbbell in your hand.

It probably goes without saying, but at nearly all times, the PowerHouse charger will be set down and used. Even though it is, in a way somewhat portable you’re not going to want to hold this and charge even the simplest of devices like your smartphone.

Functional Components:

Even though it might look like it’s complicated to use, this PowerHouse is absolutely easy to use.

All of the functional parts are on a single side. Each of the charging options has a button above them to activate that specific piece of charging, so if you want to use the AC Outlet, you’d press the AC Outlet power button and the same goes for the USB charging ports.

Once a power button is pressed, the charging indicator for that area will appear on the Blue LCD screen that the PowerHouse uses to also tell power capacity. Power capacity is told in a percentage manner and is great at giving an accurate reading of remaining power.

To make the large portable charger more able to be portable, there’s a handle at the top that makes it easy to carry and it even has a soft touch underside to make sure that when you do carry this heavy power bank that it’s made as bearable as possible.

Build

Structure and Material:

Everything about the PowerHouse feels like it’s well made and that’s primarily because it is. It has a metal casing and a few screws that hold the frame tightly together. Dropping it onto hard ground may result in damage, but what matters most is how high up it falls from because the PowerHouse can very well survive falls, bumps, and hits; it just matters more about the severity of those things.

Tech:

Something this powerful and with this amount of power capacity ought to be as safe as possible and thankfully it is. This is because the Anker PowerHouse makes use of Battery Management System (BMS) which is probably a bit of a fancier way of saying that it uses their Multi Safe Protection System. This allows the PowerHouse to have Voltage-Control, Temperature Control and many other safety tech precautions that make charging with it highly safe and reliable.

Reliability

There’s no doubt in our mind that this power bank is reliable. It has an initial power capacity of 120,000mAh which can charge most of the devices that you use on a daily basis, like your smartphone, tablet, and Laptop multiple times over. We don’t even mean 4 times or more, we’re talking about being able to charge those devices into the double digits.

It can even provide power to appliances through its AC Outlet.

Then there are the unreliable pieces that are few and ones that you probably know of from reading this review. It’s really large and very heavy at the same time too. So this isn’t a portable power source that you’re going to walk around with, and that’s really it.

The power is all there, so is the reliability and build quality. We’re gonna go out on a limb and say that even though this power bank is large and heavy, the fact that you’re able to take it with you nearly anywhere (Except for Airplanes) is just amazing.

Summary:

Power:

It has a very large power capacity and lots of charging/powering options to choose from. You’ll be able to charge lots of devices many times over and we don’t mean just your smartphone. It’ll be able to charge tablets and laptops multiples times.

Not only can it charge devices, it can power small appliances up to 160 Watts as well.

Design:

It’s really big and really heavy at 9.3 pounds. With that said, it’s at least easy to use by pressing a button at the top of each charging option, you’ll be able to start charging from that specified charging area.

Build:

Even though it’s really large, the PowerHouse is very strong and it can withstand some situations that would otherwise damage any normal power banks. Of course, the use of a plethora of safety tech features makes it highly safe and reliable to use.

Reliability:

The PowerHouse is very reliable for nearly all of your charging needs, a few of your powering needs and not that great for your portability needs.

Conclusion:

The Anker PowerHouse has proved itself to be an absolutely powerful portable charger that goes beyond what any other portable charger can deliver. We honestly find it silly to even call it a “Power Bank” or “Portable Charger” because it goes beyond just that. It has the powering capabilities of a mini generator. So yeah, it’s basically a mini generator.

Review: Intocircuit 26,800mAh 5.4A 3-Port Power Bank

High capacity power banks aren’t for the masses and that’s the plain truth. Sure, they have lots of power, more than a normal amount of charging ports so you can charge multiple devices at the same time and the charging speeds are usually really good as well. But then there’s the equivalent exchange side with power banks being large and heavy. They’re not exactly portable then and if you’re in the market for a “power bank” then you’re going to have to more precise about what kind of power bank you want. Since even these large things are power banks and are still portable.

In this case, this Introcircuit power bank is on the higher end scale of what high capacity portable chargers have to offer, let’s take a closer look.

Power

Power Capacity:

There’s lots of power with this power banks and we mean enough charging power as Anker’s PowerCore 26800. With that said, this IntroCicuit power bank doesn’t use special batteries like LG or Panasonic ones that are usually able to give a better Output power capacity than ones that don’t use them. Also, you have to take into account that this high capacity power bank use 3 charging ports, and the Max Output of the power bank is 5.4 Amps. So the more charging ports and power that you’re using, the less Output power capacity you’ll have.

For the most part, though, you’re going to want to charge 2 devices at once, and we’ll explain why in the “Output Charging” section. With 2 devices charging, you can expect an Output power capacity of 22,000mAh that you’ll actually be able to use.

It’s with this power capacity that allows you to have a ton of freedom since you can charge smartphones well over 8 times or maybe even more for smartphones that have small batteries. Even larger smartphones are perfect for charging as they can fair about 4 charges or more.

Then there are tablets that this power bank can handle as well. Charging Mini sized tablets isn’t that much of a problem because it charges a Mini one about 2.5 times. Charging full Sized tablets doesn’t hold too much trouble as you can charge one 1.5 times. Overall, when you have a power capacity of 22,000mAh with a power bank you’re going to get a ton of use out of it and that’s why portable chargers like these are great to have while you’re traveling; because you’ll always have a stable source of power.

Output Charging:

This IntroCircuit power bank uses 3 charging ports and we’re really impressed with the power behind each fo the charging ports, as well as the overall power that is provided.

Individual Charging Ports:

Each of the Output charging ports is able to supply a charging speed of 5V/2.4A. That’s a max standard charging speed and this means that they’ll charge any device that is not USB-C or Quick Charge compatible at their max charging speeds. A charging speed of 2.4 Amps is especially useful for when you’re charging tablets like iPads since their max charging speeds are 5V/2.4A

Even if you’re charging USB-C or Quick Charge smartphones, this power bank does a good job at charging them at pretty good speeds either way. The best thing, though, is that you can rest assured it’s a powerful charger and most of the devices you connect will be able to charge at either max charging speed or near them.

However, you must account for the Max Output that it can supply.

Overall Output:

The Overall Output that can be Outputted all at once is  5.4 Amps. This is great.

An Overall Output of 5.4 Amps means that you can charge 2 iPads at the same time at their max charging speed because at that point the overall charging speed is 4.8A. Then if you choose to charge 3 iPads at the same time, the max charging speed of each port will be 5V/1.8A. So if you’re charging 3 iPads at the same time they won’t be able to charge at their max charging speeds, but it’s still impressive nonetheless that all of them are charging beyond 1 Amp.

Ultimately this most likely means that if you’re charging 3 smartphones at the same time, then they will all be able to charge at their max charging speeds. We know this power bank doesn’t exactly accommodate to Quick Charge or USB-C users but it offers lots of charging power at its base and when something is built very well at the base, the whole thing tends to be really good. That’s what’s happening here.

Input Charging:

Unfortunately, the recharging isn’t nearly as impressive as the Output charging. This is because the power bank only has a single Micro-USB Input port that has a max charging speed of 5V/2.0A. If you’re using a 2 Amp wall charger, then the power bank can be recharged within 12-14 hours.

Most of the time, when power banks have a power capacity has high as this power bank does, then it usually a faster recharging design such as using 2 Micro-USB Input ports. Just take a look at this EasyAcc 26,000mAh Monster Power Bank.

Design

Size and Weight:

It’s large and it’s heavy. This is what you can expect from many other portable chargers that have the same power capacity and charging capabilities.

The Introcircuit power bank has a length of 7.2 inches, a width of 3.4 inches and a thickness of 1 inches. It’s a large one, and heavy one as well with a weight of 1.1 pounds. This isn’t the kind of portable charger that you’re going to be using in your hand since even holding it in your hand will be a cumbersome and difficult thing to do. So most of the time, it’s best to just place this into a bag and set it down on a surface when you actually want to use it.

Functional Components:

We really like how the Introcircuit power bank is designed not with the way it looks but also how refreshing it is.

Most of the functional parts are on the same general side. On the short side panel is where you’ll find the 3 USB Output charging ports, the Micro-USB input port, and a LED flashlight. On top of the power bank is where there are an LCD digital power capacity indicators that show the power capacity with 3 digits in a percentage format; on top is where you’ll also find the power button and the LCD display also features an “In” and “Out” label that is used to show when you’re using the Output and Input charging.

Charging automatically starts when you plug a device into the power bank, and that mainly leaves the power button with the function of checking the power capacity and turning on the flashlight by double tapping the power button. With that said, the power button is a little too beveled up and this causes the power button to be double tapped accidentally when you have it in a bag and that can result in the flashlight turning on and wasting power.

The LCD power capacity display is very helpful as it lets you accurately see just how much power capacity is left than just 4 power capacity indicators. We don’t really know the benefit of having the “In” and “Out” indicators, but we found that Introcircuit is quite a big advocate of Pass Through Charging since they mainly have those labels to show that Output and Input charging are happening at the same time.

Build

Structure and Material:

It’s made of plastic but it’s really durable. We don’t mean durable in the way of dropping it, but it’s durable enough to be used every day without anything major happening to it. There are just 3 main pieces that the charge is made up of, with it large center body and the 2 side panels.

Tech:

With something that has such a large power capacity, you can bet it has safety tech that is able to keep you and your devices safe during charging. However, there’s not much else to say to make the power bank extraordinary since it doesn’t use any special batteries that are able to improve longevity.

Reliability

For the most part, we can say this is a very reliable power bank. Even though it doesn’t make use of special charging technology like USB-C or Quick Charge, it’s still able to accommodate those devices to a certain degree of fast charging. For other, more standard devices, this power bank absolutely owns since each of the charging ports are able to deliver a Max Standard charging of 5V/2.4A; when you couple the overall Output of 5.4A, then that means you can potentially have 3 devices charging at the same time with them all charging at or near their max charging speeds.

The power capacity is one of the most outstanding parts since it can be reliable for anyone that’s searching for a power capacity that can last days, weeks or even months without needing a recharge. With its power capacity, this Introcircuit portable charger is able to recharge smartphones, and tablets alike, multiple times over. Portability is the main thing that could be a problem as the charger is indeed large and heavy.

Summary:

Power:

It has an Output power capacity of 22,000mAh, as a result, a lot can be done with it since you can charge many different devices, even large ones multiple time over. Charging speeds are great, at least for the Output; since each charging port is able to Output 5V/2.4A and the Max Output of the power bank is 5.4A.

The recharging could use some work as a power bank with a power capacity of 26,800mAh shouldn’t just recharge using a 2 Amp Micro-USB Input port.

Design:

It’s large and heavy, that’s to be expected for most portables that have the same power capabilities. It’s beautifully designed with it having an LCD display that aids in telling the power capacity in a more accurate way, but the power button is too high and that can result in the flashlight accidentally turning on sometimes.

Build:

For the most part, the Introcircuit power bank has solid build despite being made of plastic.

Reliability:

The reliability is for everyone, and even though it doesn’t make use of any fast and rising charging technologies; we’re really impressed by the 2.4A charging speed that each port has, and the Max Output of 5.4A is equally impressive.
