Review: Heloideo Ultra Slim Dual USB Ports Power Bank

A power bank with a built-in charging cable can mean a lot of things, but if one thing that’s true about power banks with built-in charging cables is that they’re all more reliable than ones without one. Since you’ll always have a cable to recharge the device that you use the most. With that said, power banks can just have a single charging cable, or they can even go further and just have two built-in cables and also a built-in way to recharge the power bank too.

These kinds of power banks are among the most useful and you should really consider getting them. Such as this Heloideo power bank that has quite a lot of built-in components as well as parts that you can use to use your own cables. Let’s take a closer look.

Power

Power Capacity:

The Heloideo power bank is basically a Mini power bank, and this is because it has an initial power capacity of 5,000mAh. It has an average conversion during charging which means that it’s going to have a 70% conversion rate. As a result, you will receive 3,500mAh of usable power.

Heloideo for Smartphones

A power capacity of 3,500mAh is going to be most useful for charging smartphones only. Since most smartphones are going to be able to charge at least 1-2 times. Also, the main reason this power bank should be used to charge smartphones is because most people are beginning to own smartphones that have very large batteries; that have capacities of 3,000mAh+ of power.

(You Need 1,624mAh More for a Full Recharge)

So those larger capacity smartphones are going to be able to charge only once to their full power. The Heloideo power bank does have an exceptionally low power capacity, and to have 3 charging options with such a low power capacity simply doesn’t make too much sense.

Output Charging:

There are 3 ways to charge your devices.

Built-In Cable

The portable charger has a built-in Micro-USB cable to charge your Android smartphone and any other Micro-USB compatible devices. The main flaw with the built-in cable, though, is that it’s only able to Output 5V/1.0A charging speed. So your Android smartphone may not be able to charge at its fastest charging speed.

Although the main thing about the Built-In Micro-USB cable is that you’ll always have a charging cable with you to charge.

2 USB Ports

Then there are the 2 USB ports. Each of the USB ports is able to charge at 5V/2.4A charging speeds, which is a Max Standard charging speed. Most smartphones are going to be able to charge at their max charging speeds, and tablets like iPads will charge at their max charging speeds using these ports.

With that said, the Heloideo power bank does not feature Quick Charge, so Quick Charge compatible smartphones will not be able to charge at their max charging speeds.

Input Charging:

The Heloideo power bank has two ways to recharge itself.

It uses an AC Adapter and a USB cable to recharge.

USB Cable Recharging:

The built-in USB cable to the side of the power bank is the faster way to recharge because it has a max recharge rate of 5V/2.0A. Just make sure that you’re using a 2 Amp wall charger or higher when using the USB cable method of recharging and it’ll be able to recharge it within 3-4 hours.

AC Adapter Recharging:

There’s also a retractable AC Adapter that can be used to recharge the power bank and it has a charging speed of 110V-240V/0.15A. So it’s able to recharge the power bank within the same amount of time as the USB cable; which is 3-4 hours.

Design

Size and Weight:

The Heloideo power bank is small and lightweight. The best part of this is that you get all of the lightweight and small size, along with the built-in cables.

It has a length of 5.5 inches, a width of 2.5 inches, and a thickness of 0.6 inches. The weight of it is 7.2 ounces. So it’s actually small enough that it can fit into a back pocket if you have a large enough one; and if that doesn’t work out, you can also hold it while charging your smartphone.

Functional Components:

On the long sides of the power bank is where there’s the USB cable on one side and on the other side is the Micro-USB cable. On the back is where there’s the retractable AC Adapter and on top is where you’ll find 3 LED indicators that show remaining power capacity and also a power button.

On the short side is where the 2 USB ports are. You must press the power button to begin charging.

It’s not only his power bank that does it, but another one is also capable of doing it like RAVPower’s power bank. What it’s able to do is have a lot of features that are built-in, and all the built-in components are able to easily retract themselves back into the power bank.

Build

Structure and Material:

The Heloideo power bank has a solid build even though it’s made of plastic, but even so, it’s still able to take light falls and bumps, but nothing too serious.

Tech:

On the tech side, it makes use of the basic tech features that are able to keep charging safe for the power bank and for you.

Reliability

Of course, since it has a Micro-USB built-in cable, the power bank is mostly geared towards people that are able to make use of it and ultimately will be more reliable for that user. Which is why iPhones users should look for other power banks with built-in cables that have Lighting cables that are built-in.

With that said, the power bank has two USB ports that can be used by any cable and its use of two way to recharge is very helpful because if you don’t have an AC Outlet, then you can use a USB wall charger and vice versa.

The most unreliable thing about this power bank, though, is the low power capacity and its many charging ways.

Summary:

Power:

There’s not much power capacity, but if the power capacity were higher, then the power bank wouldn’t be as small as it is. There are 3 charging options and 2 Recharging options which are very helpful.

Design:

It’s a small and lightweight power bank, and even with its many built-in components, it does a great job with concealing all of its parts.

Build:

It’s all made of plastic which was actually a good choice because it makes the power bank lightweight and even though plastic is thought to be weak, the Heloideo power bank holds up quite well.

Reliability:

Since it has a built-in Micro-USB cable, the power bank is going to be most reliable for those that can recharge using it. The use of its other 2 built-in cables and 2 USB ports are very reliable no matter what device you’re using.

Specs of the Heloideo Ultra Slim Dual USB Ports Power Bank:

  • Capacity:            Advertised: 5,000mAh           Real Capacity: 3,500mAh
  • Output:

Built-In Micro-USB Cable: 5V/1.0A

USB Ports: 5V/2.4A

  • Size: 5.5 x 2.5 x 0.6 inches
  • Weight: 7.2 Ounces

Conclusion:

Power bank like this Heloideo portable charger is great examples of what can be done with cables that are built straight into power bank. You have more reliability and less care of forgetting cables at home. And more focus on moving forward.

Review: Mosche 3-In 1 Power Bank

There are a lot of options that we have to charge our electronics. Car chargers are for when we’re driving, USB wall chargers are useful for stationary power and also when we want to charge many devices at once. Power banks are one of the best charging electronics though because portable power means that you can charge your devices anywhere, but the other two technologies aren’t there.

In this case, this Mosche power bank is a 3 In 1 charger. It acts as a Car, Wall and power bank charger at once and it might just be the most useful charging electronic on the market. Let’s see why.

Power

Power Capacity:

The power capacity of the power bank is only 2,600mAh, it’s not a very high power capacity at all. With that said, the goal of this charger wasn’t to provide the highest power capacity, the purpose is to be as useful as possible.

A power capacity of 2,600mAh is going to charge most smartphones at least one time and most likely a little less than a full charge because power is lost during charging. We admit that it’s not a lot of power, but it’s enough to get smartphones powered up to where they need to be.

(You Need 400 More Power Capacity)
Samsung Galaxy S7 Edge2,600mAh3,600mAh0mAh
0.7 of a Charge

(You would need 1,000mAh more power capacity)

The main aspect lies within all 3 of the charging abilities of the charger, since having a power capacity means that it’s a portable charger.

Output Charging:

There are 3 ways to use this charger. It can be used as a Car charger, USB wall charger, and a power bank.

Charging Speeds

Charging works the same way with all 3 of the charging ways. There are two charging ports on the power bank, and each of them are able to Output of 5V/1.5A and the Max Output of the charger is 5V/2.1A. So it doesn’t have the greatest of charging speeds, because if you’re charging 2 devices at once, then each one will be able to get 1 Amp of charging speed.

However, the main point of this power bank is just how well you can use it. I say this because this is the universal charger, as you can take with you anywhere and have the ability to charge your smartphone anywhere. Take a look at the charging options below.

Power Bank:

Just like any other power bank, you don’t have to plug it into anywhere as it already has a power capacity and you can plug your devices into the USB ports to have portable charging.

USB Wall Charger:

The power bank has a Built-in Adapter that you simply plug into an AC Outlets and it can be used as a wall charger.

Car Charger:

There’s a car charger port that’s also built into the power bank, all you have to do is just plug it into your car’s V12 outlet and it’ll be ready for charging.

Input Charging:

Not only is the USB wall charger and Car charger option used to charge your devices, but it’s also used to recharge the power bank. The Mosche power bank is able to recharge within 3-4 hours. With that said, just remember that recharging the power bank is only for the power bank portion and that you can still use the Wall and Car charger options without a power capacity.

Design

Size and Weight:

This is the 2nd part of where the power bank shines the most. Since it’s so small and lightweight that this 3 in 1 charger can be taken anywhere.

The Mosche power bank has a length of 3.1 inches, a width of 2.7 inches and a thickness of 0.9 inches. The weight of the power bank is 0.9 ounces. So it’s very portable and can be taken anywhere. In fact, if you do get this power bank, then it’s best to take it anywhere you go because it’s just that small and useful.

Functional Components:

On one side of the power bank is where there are the 2 USB ports and they’re separated by 4 Blue LED power capacity indicators. The power button is in the center of the power bank.

On the two side is where you can find the Car charger and AC Adapter. Both of them are retractable into the power bank and when done so, the power bank just becomes a block and that makes it very portable since there aren’t any protruding pieces.

Build

Structure and Material:

The entire Mosche power bank is made of plastic, but the structure is still quite solid. We have our doubts that something this small and useful could have a good build quality, but our doubts were false because the AC adapter and Car charger port are both built-in very well into the charger.

Tech:

The Mosche power bank does have a CE and RoHS certifications, and that basically means it fits the basics of both safety tech and the material that it’s using. Thankfully, even with the many ways that it can be used, there aren’t any heating problems and that can mostly be attributed to a low Max Output, which is a smart call for a device that has 3 charging ways.

Reliability

It has a very low power capacity and quite the slow charging speeds. With that said, those are not the major points of the charger.

What does dictate its reliability is that you can use this power bank in nearly every charging situation and it’ll get the job done. Portable power is just one facet. It’s going to reliable in two other major ways that you can find use in for everyday situations.

Summary:

Power:

The power capacity is enough to charge most smartphones at least once. Charging isn’t the fastest but you can use this power bank not only for portable power but also for Car and Wall charging needs too.

Design:

It’s very small, and as a result, you can take this 3 in 1 charger wherever you go.

Build:

Although it’s not Rugged power bank and you shouldn’t go dropping it, the built-in components like the car and wall charger parts are placed very well.

Reliability:

One of the most reliable power banks. Sure it might not have the highest power capacity or fastest charging speed but it acts more than just a power bank.

Specs of the Mosche 3-In 1 Power Bank:

  • Capacity:    2,600mAh
  • Output:   Per Port: 5V/1.5A       Max Output: 2.1 Amps
  • Input:     5V/1.0A
  • LED Power Indicators: 4 LED Dotted Power Capacity Indicators
  • Size: 3.1 x 2.7 x 0.9 inches
  • Weight: 0.9 Ounces

Conclusion:

Most the time when a power bank is reliable, we think of ones that have built-in charging cables or high power capacities; don’t get us wrong, though, those kinds of power banks are highly useful, but their purpose is singular.

This Mosche 3 in 1 power bank opens up doors to other charging electronic and that makes it universally useful.

Review: LAX 4,000mAh Power Bank with Lightning and Micro-USB

Nearly every charging electronic requires a charging cable, or rather, EVERY charging electronic needs a charging cable. Whether it’s a USB wall charger, car charger or even a wireless charger, they all need charging cables to actually be utilized. With that said, a power bank is one of the charging electronics that needs a charging cable while you’re on the go. Leaving your house with your power bank is great, but not so great when you forgot to unplug your charging cable from your USB wall charger that’s in your room. As a result, you’re stuck with a useless source of power.

This is why power banks with built-in charging cables exist because now you’ll always have a charging cable or two with your power bank. That is what this LAX 4,000mAh Power banks accomplishes.

Power

Power Capacity:

For having a 2 built-in charging cable that gives the ability to charge two devices at once, this power bank has quite a low power capacity of 4,000mAh. However, the Max Output of 2.0 Amps evens it out because then you manage to lose less power capacity during charging. As a result, the conversion rate of the LAX power bank is about 75%, which is going to leave you with 3,000mAh of useable power.

Mostly Meant for Smartphones

It’s a small power capacity, and this is mainly because this is a Mini power bank. So you’re going to be able to get about 1 or 2 full charges for most smartphones. Another important thing to note is that even though there are two built-in charging cables, you should still charge devices 1 at a time so you make use of as much power capacity as possible for the device that you want to charge the most.

You can charge tablets with the power bank, but the power capacity isn’t enough to be worthwhile for tablets in the first place.

Output Charging:

 

There are two convenient charging options available.

A Lightning cable on one side and a Micro-USB cable on the other side. The max Output power that is available is 5V/2.0A at once. This is disappointing at first, because if you’re charging two devices at once with this power bank, then each cable will have approximately 1 Amp of speed to use.

This is why even though it’s great to have two built-in cables, it’s best to charge a device at a single time for power capacity and charging speed benefits; as you’ll have 2 Amps of speed when you charge a device alone.

It’s already a mini power bank, and the fact that it has two cables is already impressive, it’s not surprising that it has power capabilities to match the Mini size.

Input Charging:

Recharging is done through a Micro-USB Input and the max charging speed for recharging the power bank is 5V/1.0A. As long as you’re using 1 Amp wall charger or higher to recharge the power bank, then it’ll be able to recharge to full power within 2-3 hours.

Design

Size and Weight:

It’s a very small and lightweight power bank that is going to be very portable.

It has a length of 4.6 inches, a width of 2.4 inches and a thickness of 0.4 inches. The weight of the power bank is 4 ounces.

So it’s basically the size of an iPhone 5, which means that you can easily carry this power bank in your hand while you charge your smartphone; or you can place it in your pocket.

Functional Components:

The two Built-in charging cables are to the side of the power banks and each of them is 5 inches long. The Micro-USB Input port to recharge the power bank is on the short side. Lastly, on top of the power bank is where there are the power button and a LED power capacity indicator.

The power button isn’t really a button, more of a sensitive touch area that you have to press down on to begin charging. Also, there aren’t multiple LED lights to show the power capacity. Instead, there’s just one Blue LED light that blinks to show the amount of power capacity that’s left.

4 Blinks = 100%

3 Blinks = 75%

2 Blinks = 50%

1 Blinks = 25%

This kind of method to measure power capacity is highly unusual and rather difficult to check the power. It would be better to have multiple lights to check the power.

Build

Structure and Material:

The entire power bank is made of plastic, and it has a very strong build.

Tech:

On the tech side, the power bank has lots of safety tech features to make sure that charging is stable when you’re charging 1 or 2 devices at once.

Reliability

The main reason that you’re getting this power bank is because you have both Micro-USB and Lightning chargeable devices. Once you get this power bank you’ll have a chance of charging those devices at all times with the power bank because the power bank has those cables built-in. So the reliability is really good because you’ll always have the necessary cables to actually use the power bank.

With that said, the power capacity is small and will only be able to charge most smartphones 1 or 2 times at most. It’s a Mini power bank that has 2 Built-in charging cables.

Summary:

Power:

It only has 3,000mAh worth of usable power capacity. Also, the Max Output of power is 2 Amps at once. It might seem rather bad, but the powering capabilities of the power bank go right in line with what the power bank is. Which is a Mini power bank, that has two built-in charging cables.

Design:

It’s as small as an iPhone 5, and that means you can hold it in a single hand or place it into your pocket. Portability is not an issue. However, the way of telling the power capacity could be better.

Build:

The entirety of the power bank is made of plastic. Not a rugged power bank but it holds its own.

Reliability:

If you have both Micro-USB and Lightning devices, then this power bank is going to be useful as you’ll always have a way to recharge both of those kinds of devices.

Specs of the LAX 4,000mAh Power Bank with Lightning and Micro-USB:

  • Capacity:            Advertised: 4,000mAh            Real Capacity: 3,000mAh
  • Output:  5V/2.0A Max Output
  • Input:      5V/1.0A Via Micro-USB Input
  • LED Power Indicators: Single Blinking Light
  • Size: 4.6 x 2.4 x 0.4 inches
  • Weight: 4 Ounces

Conclusion:

The LAX power bank is a very capable portable charger that might seem underpowered, because, well it is. But with the two built-in cables, the power bank is better than most mini power bank because it can charge two devices at once with cables that will always make it useful.

Review: Anker PowerCore Fusion

The goal of power banks is to become the best portable power source, and that is one of the main reasons that power banks are one of the best charging electronics today. Since it’s charging power that you can anywhere, every other charging electronic out there is going to have you chained down to just a charging cable. However, power banks come in different sizes, and categories and each of them bring new innovation to how the power banks can be useful. With that said, the main thing for a power bank is having the ability to be a lot of things while still holding power and portability.

That’s what Anker has achieved with this Anker PowerCore Fusion. It’s a USB wall charger as well as a power bank.

Power

Power Capacity:

This Anker PowerCore Fusion has a power capacity of 5,000mAh. You’re going to be getting a pretty average conversion during charging with a 70% conversion of its initial power capacity. With that, you’re going to be able to get a 3,500mAh power capacity to actually use with the devices that you charge.

Anker PowerCore Fusion for Smartphones

So this means that this power bank is most useful for charging smartphones because most smartphones have a power capacity that is as high as the Output power capacity or near it. This isn’t a bad thing though since high capacity smartphones like a Galaxy S7 is going to be able to charge to its full power once, and for a large capacity smartphone that’s actually a lot. For smaller capacity smartphones like a normal iPhone 6 will be able to get about 2 full charges.

That’s really the purpose of this power bank in the first place, is to be used by smartphones.

Not Really for Tablets

Using the Anker PowerCore Fusion with larger devices like tablets isn’t going to bode well since not even this power bank is able to charge Mini tablets to their full power.

Output Charging:

There are two USB ports on the PowerCore Fusion.

When you have the PowerCore Fusion plugged into an AC Outlet

The Anker PowerCore Fusion is able to plug into an AC Outlet because it has a built-in AC adapter. However when you plug the power bank into an AC Outlet, the charging speeds of the ports go down and this is mainly done so the power bank doesn’t damage itself with overheating; since when you plug the power bank in an AC Outlet, it’s recharging and that is called Pass Through charging. As you can use the power bank and recharge it at the same time.

So while the power bank is plugged in, the charging speed of each port is 5V/2.1A.

PowerCore Fusion by Itself

When the PowerCore Fusion is being used as a power bank, then each of the ports is able to Output 5V/3.0A. That’s a very fast charging speed as most smartphones are going to be able to charge at their max charging speeds. Additionally, a 3 Amp charging speed is going to be able to charge USB-C compatible devices near their max charging speeds; but it’s important to know that USB-C compatible devices are really only able to charge at their max speeds when you’re using a USB-C to USB-C connection.

This power banks and other Anker power banks like this Anker PowerCore II are taking the first steps to making 5V/3.0A charging speeds a standard on power banks now.

Input Charging:

There are two ways to recharge the PowerCore Fusion. You can use the AC Adapter by plugging the power bank into an AC Outlet, or you can use the Micro-USB Input port.

Recharging Using the AC Adapter

The charging speed of the AC Adapter is 100-240V~0.5A 50-60Hz; however, it’s important to know that if you’re charging your smartphone while the power bank is plugged into an AC Outlet, that charging your smartphone is the priority and recharging of the power bank happens after your smartphone or other device is fully charged.

Recharging Using the Micro-USB Input Port

The Micro-USB Input port has a max recharge rate of 5V/2.0A. So you should use a 2 Amp wall charger or higher to get the fastest recharge speed. Either way, using both recharging methods will result in the same recharge time of 3-4 hours.

Design

Size and Weight:

It’s a very small and lightweight power bank. Or is it a USB wall charger?

It has a length and width of 2.8 inches and the thickness of the fusion is 1.2 inches. Very small, although the thickness is quite large and might make it difficult to place into a pocket. It weighs 6.7 ounces, so it’s very lightweight and when you couple that with its very small size, then this power bank can easily be held in a single hand.

Functional Components:

It’s as easy to use as it’s easy to hold.

On the front facing side is where there are 2 USB ports and the Micro-USB Input port. On the side of the power bank is where there’s the power button, and 3 Blue LED power capacity indicators.

Lastly on the other end of the power bank is the AC Adapter that is able to fold in and out of the power bank. This is very convenient because when you fold the AC Adapter in, all the sides are even and the PowerCore fusion practically becomes a square.

Charging automatically starts when you plug a device into the power bank to recharge, and that leaves the power bank with the ability to check the power capacity left.

Build

Structure and Material:

Even though the PowerCore fusion is made of plastic, it’s built very well with none of its parts being loose or poorly placed. With that said, don’t go dropping it because it will get damaged, but in a constant use kind of way this power bank is very strong.

Tech:

The Anker PowerCore Fusion makes use of Anker’s Multi Safe Protection System that is able to keep charging safe for your and your devices. Best of all, it’s great that charging speed decreases when the power bank is plugged into an AC Outlet so the power bank doesn’t overheat and damage itself during charging.

Reliability

This is basically a Mini power bank because it has a 5,000mAh power capacity that is able to charge most smartphones one single time. So you’re not getting this power bank for a long lasting power capacity.

However, the reliance is on the double feature that it has. Since you can use this as a USB wall charger, have the power bank fully charged, and then disconnect it. Once disconnected, the USB wall charger becomes a portable charger that can practically be taken anywhere and offers fast charging.

The main reason this power bank has 2 USB ports is because it’s a USB wall charger and is basically like the Anker’s PowerPort 2. Having the 2nd port in power bank mode is just a plus.

Summary:

Power:

It’s a USB wall charger and power bank in one. The power capacity is only going to be able to charge smartphones to their full power at least once or twice. The charging speed is lower when the power bank is plugged into a USB wall charger and speeds are faster when it’s in power bank form.

Design:

The size is very compact with the power bank basically being a small square and very light weight.

Build:

There aren’t any reinforcements to save the power bank from a fall but it’s still a solid power bank.

Reliability:

This is not only a reliable power bank, it’s also a reliable wall charger as you can use it while you’re stationary and keep the charging going while you’re on-the-go.

Review: Jackery Pop Slim

Slim power banks are the most useful kinds of mini power banks. The alternative to them is using the portable charger that is cylindrically shaped but those can be quite thick and aren’t going to be able to fit into your pocket as easily. This is why, at Charger Harbor, we much prefer Slim power banks and we think you would too since most of them are about the same size of a smartphone; and as a result, they’re easy to hold and even place into your pocket.

This is the Jackery Pop Slim. We’ve already reviewed one of Jackery’s other Slim power banks called the Jackery Air 6 and it proved to be very capable with its portability and design, but ultimately the powering side of it was quite weak. Let’s see if this Jackery Pop has more to provide with its power while still holding onto its Slim Roots.

Power

Power Capacity:

The power capacity of the Jackery Pop Slim starts at 5,000mAh and you’re not going to be losing a lot of power during charging. This is because this power bank only uses a single charging port, so, during charging, the conversion of power is only happening for a single device. That’s going to result in the power capacity having a conversion rate of about 75%, which is better than the average conversion rate and as a result, you’re going to be able to use 3,600mAh of its power capacity.

Pop Slim for Smartphones

It’s with an Output power capacity of 3,600mAh that you’re going to be able to charge most smartphones 1 and a half times. An Even smartphone that have high power capacities, like the Galaxy S7, Google Pixel, or iPhone 7 Plus; those smartphones are able to charge to their full power at least once with the Jackery Pop. It’s a perfect power bank for a smartphones because of its power capacity, and portability.

Pop Slim for Tablets

However, if you’re planning on charging larger devices that have higher battery capacities, then it’s most likely not going to be able to charge a device like a tablet to its full power. If you do plan on charging a tablet, a Mini tablet like a Galaxy Tab is going to fair well since most of them have a battery capacity of 4,000mAh.

Output Charging:

There’s only a single charging port. The USB port has a charging speed of 5V/2.1A. It’s actually a very good charging speed considering that this is a Slim power bank, and the charging speed is going to be able to charge most smartphones at their max charging speeds. At least this is going to be true when you’re charging a smartphone like an iPhone 6 and other iPhones beyond that because their max charging speeds are at 2 Amps.

However, this power bank will not be able to charge Quick Charge compatible smartphones at their max rate, because it doesn’t feature Quick Charge. Although, a 2.1 Amp charging speed will still fair well.

Input Charging:

The recharging speed is also good because the Jackery Pop Slim power bank is able to recharge at 5V/2.2A. You should a 2.4A USB wall charger to recharge the power bank as fast as possible, and that will result in a full recharge within just 3 hours.

Design

Size and Weight:

The size and weight of the Jackery Pop are the best parts of the power bank. Since it’s basically the size of a smartphone and is just as lightweight too.

It has a length of 4.9 inches, a width of 2.5 inches, and a thickness of 0.4 inches. The weight of the power bank is 5.1 ounces. So you can place this power bank in your pocket, possibly along with your smartphone and have it charging your phone. Holding it doesn’t pose any problems either because you can just stack your phone on it.

Functional Components:

All of the functional parts of the power bank are on a single side. That’s where you’ll find the Micro-USB Input, the USB Output port, 3 Green LED power capacity indicators and the power button. Charging automatically starts when plugging a device into the USB port and it automatically stops charging either when the device your charging is fully recharged or when there is no longer a device connected to the power bank.

Build

Structure and Material:

The center part of the power bank is made of Aluminum and the two side parts are made of plastic. It’s a well-built power bank that won’t fall apart with constant use. With that said, it’s still very open to being damaged by drops and water, so don’t treat it roughly.

Tech:

Surprisingly, this Slim Jackery power bank uses Lithium Ion batteries rather than Polymer ones. As a result, heating issues aren’t a prevalent problem and that’s one of the main reasons that you’re able to receive such a good conversion rate during charging. In addition to that, the Jackery Pop makes use of safety protections to keep you and your devices safe.

Reliability

The Jackery Pop is going to be most reliable for when your charging smartphones because it has a power capacity that’s going to be able to charge most smartphones once to their full power and just a single charging port. It optimizes very well for charging smartphones too because the power bank has a good conversion rate to provide the most power and a charging speed that delivers well.

Aiming for larger devices like a tablet to charge with this power bank is going to be a mistake as you’ll be disappointed with its performance.

Also, the portability is the most noticeable feature as you’ll be able to take it nearly anywhere with ease.

Summary:

Power:

The power capacity has a good conversion and the charging speed through its single port performs well with most smartphones.

Design:

It’s very small, has the thinness of a smartphone and it’s also very lightweight. Just like owning a second smartphone.

Build:

It has a good build, but it’s good to be very cautious of dropping this power bank because there’s nothing to protect it from shock damage.

Reliability:

The reliability is great for when you’re using it with smartphones, not so much when it comes to larger devices.

Specs of the Jackery Pop Slim:

  • Capacity:            Advertised: 5,000mAh            Real Capacity: 3,600mAh
  • Output:   Per Port: 5V/2.1A
  • Input:      5V/2.2A Via Micro-USB Input
  • LED Power Indicators: 4 LED Dotted Power Capacity Indicators
  • Size: 4.9 x 2.5 x 0.4 inches
  • Weight: 5.1 Ounces

Conclusion:

This Jackery Pop Slim power bank, in a lot of ways, is better than the Jackery Air 6. It has a better power capacity, faster charging speed and a better build too. If you’re having a hard time choosing which Jackery Slim power bank you should choose, then this one is it.

Review: Kans Ultra Compact 4,000mAh Portable Charger

A power bank that has a small power capacity means that it’s a small power bank. Small power banks are very useful when you want to take portable power with you anywhere because these power banks with small capacities are able to be lightweight so they’re easy to hold and they’re also small enough that they can fit into your pocket. With that said, it’s also important to know that most of the time, these kinds of power bank are only going to be good for 1 or 2 full charges for your smartphone and that most of them of have 1 charging port only.

In this case, this Kans 4,000mAh power bank has a few unusual traits that you wouldn’t expect and even though they seem quite silly to have, these charging capabilities are still useful to use.

Power

Power Capacity:

How Much Power You can Get

The power capacity of this Kans power bank starts at 4,000mAh and it actually has quite a good conversion rate of 75% and that going to leave you with about 3,000mAh of usable power.

Mostly Meant for Charging Smartphones

Overall, the power bank is mainly mean to be used with smartphones because if you own a smartphone like a Galaxy S7, an iPhone 7 Plus or a Google Pixel; those smartphones that have power capacities of near or at 3,000mAh, then you’re going to be getting one full charge. Of course, you might own a smartphone that has a lower battery capacity in the 1,500mAh range and those might be able to charge 2 full times.

(You would need 600mAh more power capacity)

For the most part, using this power bank with a smartphone is the ideal way to use it. Charging tablets with the Kans power bank is going to charge Mini tablets about half way through only.

Output Charging:

Surprisingly there are two charging ports on this 4,000mAh power bank, or should we say, a 3,000mAh power bank that’s actually how much you’ll be using.

One of the charging ports has a charging speed of 5V/1.0A and the other charging ports have a charging speed of 5V/2.0A.

It’s best to use the 2 Amp charging port at all times and to use the 1 Amp charging ports only when you’re charging two devices at once. With that said, it’s very important to remember that charging 2 devices at once will split up the power capacity, and so if you’re charging two smartphones at once, both of them will mostly only charge about halfway through.

Input Charging:

The Kans power bank has a recharge speed of 5V/1.0A using a Micro-USB. As long as you’re using a 1 Amp wall charger or higher to recharge the power bank, it’ll be fully recharged within 3-4 hours.

Design

Size and Weight:

It’s a small and light power bank that you’re going to easily be able to take anywhere.

This is because it has a length of 3.8 inches, a width fo 2.4 inches and a thickness of 0.3 inches. The weight of the power bank is 2.4 ounces. Very small and lightweight; you can even fit the power bank into your pocket.

Functional Components:

On the short side is where there’s two USB charging ports and in the middle is the Micro-USB Input port.

On the long side of the power bank is a power button; lastly, on top is where you’ll find 4 Blue LED power capacity indicators.

Charging automatically starts when you connect a device to the charging ports and charging stops when there aren’t any devices connected to the power bank.

Build

Structure and Material:

The Kans power bank is made plastic, and it’s actually built quite well. It can take light falls but nothing too serious.

Tech:

On the tech side, the power bank makes use of the basic tech features to keep you and your devices safe during charging. It doesn’t overheat.

Reliability

We think the Kans power bank is going to be most helpful for those that are always on-the-go and only expect one full charge from this power bank. This is because that’s the reliability that this power bank can offer with its power capacity and size.

This power bank is not going to charge a smartphone multiple times, or at least not most smartphones, and charging two devices at once just seems unnecessary.

Summary:

Power:

The power capacity is only good for charging smartphones and the use of 2 charging ports is quite silly because if you’re charging two smartphones at the same time, that’s just going to result in half a charge for both of them.

Design:

Its size and weight are the most powerful parts of this Kans power bank because it’s really small and barely weighs anything which makes the portability great.

Build:

Not the strongest build but it holds up well with daily use.

Reliability:

This power banks has very limited capabilities and it’s really meant for a single charge while you’re on the go.

Specs of the Kans Ultra Compact 4,000mAh Portable Charger:

  • Capacity:            Advertised: 4,000mAh            Real Capacity: 3,000mAh
  • Output:  USB Port 1: 5V/2.0A    USB Port 2: 5V/1.0A
  • Input:      Both Micro-USB Input Ports: 5V/2.0A       Max Input: 4 Amps
  • LED Power Indicators: 4 LED Dotted Power Capacity Indicators
  • Size: 3.8 x 2.4 x 0.3 inches
  • Weight: 2.4 Ounces

Conclusion:

Simplicity is the name of the game when it comes to this power bank because it doesn’t do anything special. The power capacity is best used for smartphones only and what should be only a single charging port; this power bank actually has two.

We think the portability is the one the main reasons to purchase this power bank.

Review: Jackery Jewel Lightning Power Cable

Power banks are a versatile type of charging technology because they can be mended into many different technologies. Sometimes they double as wall chargers and some are even car chargers. Some power banks can be really big because they have a high power capacity and some are really small because they have a small power capacity. If one thing is certain about portable chargers is that they’re, well, portable. That is the main thing within their nature that will always be prevalent because it’s power without the setbacks.

In this case, though, the power bank takes a whole new form that is quite uncommon but highly sophisticated to use which is being implemented into a charging cable.

Power

Power Capacity:

So the power capacity of the Jackery Jewel charging cable power bank is very low because the power bank part of the charging is very small since it uses a very tiny Lithium Ion battery. The power capacity it provides is 450mAh and even though that’s not a lot of power, that’s not really the point of the Jackery Jewel. What is the point is that the charging cable even has a power capacity to use.

With that said, the charging cable is the only useable for Apple devices like iPhones and iPads that are able to use a Lightning charging cable. For most iPhones, you’re going to at least get about 15% of battery capacity and that can increase your standby time to about 3 hours. We realize that Jackery claims that the Jewel is able to restore about 20% more battery life left, but at Charger Harbor, we also account for energy lost during charging.

Also, even though you can use the Jackery Jewel on iPads, it won’t be very useful because the power that it restores is going to be very minuscule.

Output Charging:

Output charging speeds are expected to be slow for a power bank that is so tiny. The Jackery Jewel has an Output charging speed of 5V/1.0A.

So it won’t charge your iPhone 6/7 or iPad at their max charging speeds, but at least it’ll charge them. There’s no need to connect the charging cable to a USB wall charger until the power capacity the Jewel has is fully depleted, so that means you can just connect the charging cable to your phone and it’ll begin charging.

Input Charging:

The recharging speed is the same as the Output with it being able to recharge at 5V/1.0A.

Recharging of the Jackery Jewel Light Cable power bank is done by connecting it to a USB wall charger and that will result in the power bank being recharged, and if you’ve got your phone connected while it’s being recharged then the Jackery Jewel will also begin charging your phone.

Design

Size and Weight:

The charging cable is 3.3 Feet long and weighs 1.2 ounces. Even with the addition of a power bank section on the charging cable, it’s just as portable as any charging cable.

Functional Components:

 

Well, the Jackery Jewel is basically like any other charging cable, but this one has a power bank in the center of it. The power bank portion of the charger is about 3 inches long.

When you’re using the Jackery Jewel just by itself, then the button must be pressed to begin charging. If charging is happening through a USB wall charger then you don’t need to press the button because charging automatically starts.

Build

Structure and Material:

The charging cable has a very usual build because it’s just wrapped in rubber and so is the power bank portion of the charger. However, the power bank piece of the Jackery Jewel has been drop tested and that can be thanked to the wrapping that’s around it.

Tech:

Even with its small size, the charger is still able to hold lots of certifications because it has about 9 layers of safety features. The certifications that it has to include are RoHS, FCC, and CE.

Reliability

We think that the Jackery Jewel is a beautifully executed concept, but it’s important to remember what it offers.

It’s only limited to devices that can take the Lightning charging cable to charge, and the power capacity of the built-in power bank is only 450mAh that can only add 15% of the power capacity. It’s the fact that you can have portable power and a charging cable that makes the Jackery Jewel so useful to use.

Summary:

Power:

The power capacity is just enough to give you about 15% of power capacity and just has a charging speed of 5V/1.0A.

Design:

Very well designed. You can charge through the power bank by just connecting the charging cable into a device, and press the power button to begin charging. All without needing to connect the charging cable to a wall charger.

Build:

It’s quite sturdy with the Jackery Jewel actually being drop tested.

Reliability:

It’s not capable of providing near a full charge at all, and neither can it provide the fastest charging speeds. However, what the Jackery Jewel can provide is power and charging when you need it most and it can provide just enough of it.

Specs of the Jackery Jewel Lightning Power Cable:

  • Capacity:            450mAh
  • Output:   5V/1.0A
  • Input:      5V/1.0A
  • LED Power Indicators: Just uses a small Green Light
  • Size: Charging Cable is 3.3 Feet long and the Power Bank portion is 3 inches long
  • Weight: 1.2 Ounces

Conclusion:

There’s not many like it, and we actually think that the Jackery Jewel is basically the first of its kind so it’s hard to give it some standards.

However, for what it can do, the Jackery Jewel is an amazing portable charger and even with its heavy limits, it’s still able to provide just enough power and a beautiful design that is fantastic to use.

Review: Opteka-SC4000 Thin Solar Power Bank

Solar power banks might sound useful and even though they’re basically more useful that your regular power bank, there are still a lots reasons why you shouldn’t just go chasing these solar charging devices. They can indeed recharge themselves through the sunlight and possibly any other source of light, but these kinds of chargers are usually lacking in other areas; like their charging speeds, design and even the solar recharging itself being the main part of the device.

This is the Opteka 4,000mAh solar power bank and although it might look quite sleek and professional, we’ll reveal what it really has to offer in this Charger Harbor review.

Power

Power Capacity:

The power capacity of the Opteka is started at 4,000mAh and that’s not what you’re really going to be receiving because the power bank uses Lithium Polymer batteries that aren’t good at converting their energy and as a result, you’re most likely going to receive an Output power capacity of 3,000mAh that you can actually use to charge your device.

It’s a pretty big disappointment because what was meant to be a power capacity that would provide 2 full charges to your smartphone, this Opteka can only provide 1 full charge to most smartphones like your iPhone 6 / 6s Plus smartphones. Having a single charge is very true for larger capacity Android smartphones once you’re charging Galaxy or a Google Pixel smartphones.

If you’re thinking that you can charge tablets with this power bank, you can, but it’s not worth it at all since both the power capacity and charging speeds are not going to provide you with a good experience when charging a tablet.

1 Full Charge
Samsung Galaxy S7 Edge3,000mAh 3,600mAh-600mAh
Need 600mAh of More Power Capacity for a full recharge

Output Charging:

The Output charging isn’t that fast because it can only Output 5V/1.0A. A 1 Amp charging speed is a slow one and it’s not going to charge most of your USB charging devices at their max charging speeds.

This is true for smartphones and very true for devices that are tablets and smartphones that are compatible with Quick Charge.

Input Charging:

Solar Recharging:

The solar recharging like on many other solar power banks isn’t that fast and when you have the power bank in direct sunlight with light hitting the solar panel, the max recharge rate of the solar charger is 5V/250mA. That’s basically a Quarter of a single Amp and so if you’re solely recharging the power bank through its solar panel, it will be able to be fully recharged within 12 hours.

However, most of the time you’re not going to fully recharge it from the sun because most of the time it won’t be in direct sunlight and of course, the Opteka can only charge to 75% when it’s being recharged through solar means.

Mini USB Recharging:

Okay, this isn’t’ recharged normally like most portable chargers on the market because you have to use a Mini USB charging cable to recharge the power bank and when you’re recharging the Opteka through the Mini-USB port, its charging speed is 5V/1.0A.

It has a recharge time of 6 hours when being recharged through the Mini-USB Input Port.

Design

Size and Weight:

Even though the power bank isn’t that powerful, it sure is portable because of its small size and weight.

This is because it has a length of 4.5 inches, a width of 3.3 inches and a thickness of 0.5 inches. The weight of the power bank is 6.5 ounces. So it can potentially fit into your pocket if you really wanted it to but it’ll still be a tight fit.

Functional Components:

It’s easy to use with all the functional pieces in the same general area. The USB Output charging port is on a short side and the Mini USB Input is there too. At the top is where you’ll find the power button and 4 Blue LED power capacity indicators. You need to press the power button to begin charging.

Build

Structure and Material:

Not the most durable Solar power bank and that’s really bad because a solar power bank is supposed to have a strong build because the assumption is that you’re going to take this into the outdoors for when you’re camping or hiking.

As a result, dropping the Opteka solar charger can result in damage, and it’s not waterproof at all, so you shouldn’t keep it out in the rain. It’s made of plastic.

Tech:

The power bank makes of a few of the main safety measures like Short-Circuit and Surge protection. It also shuts off charging once your device is fully recharged.

Reliability

For the most part, the Opteka is not a reliable portable charger. It doesn’t provide enough Output power capacity to charge smartphones multiple times, the charging speeds for the Output, Input Solar and Mini USB charging are all slow and the build quality is very poor. You can’t really justify taking this power bank into the wilderness because it isn’t built for that and it can easily get damaged.

Summary:

Power:

The power capacity is on the lower end and can at most, charge your smartphone once. Charging speeds are slow and the solar recharging is barely going to be used because it’s so slow.

Design:

Probably the best aspect of the power bank because it’s a small and lightweight charger.

Build:

It’s not a rugged solar power bank, so it can’t take falls and it isn’t waterproof. Not really meant for the outdoors.

Reliability:

With all of its aspects put into one, the reliability of this power bank solely hangs onto how portable it is because all the other parts are lacking in quality and power.

Specs of the Opteka-SC4000 Thin Solar Power Bank:

  • Capacity:            Advertised: 4,000mAh            Real Capacity: 3,000mAh
  • Output:   5V/1.0A
  • Input:    5V/1.0A Via Mini-USB Input Port
  • LED Power Indicators: 4 LED Dotted Power Capacity Indicators
  • Size: 4.5 x 3.3 x 0.5 inches
  • Weight: 6.5 Ounces

Conclusion:

The Opteka solar power bank tries but it does have the right amount of power or build quality to even be a solar power bank. It’s great that it can charge through sunlight but that doesn’t mean much when the charging speeds that your devices are going to receive are really slow.

Review: Levin Ultra Compact 5,000mAh USB External Battery

A New Age of Mini power banks is really challenging what makes power banks, well, Mini. These kinds of portable chargers are still small but they’re not as compact as say, the Jackery Mini or the Anker PowerCore+ Mini portable chargers. This mostly because since the power capacity of the charger is higher, as a result, the size of the battery will be larger. Of course, all that’s used with these kinds of portable chargers is just a single battery but the size of the battery is rather large and this can lead the people who thought it was smaller to be disappointed as it’s not as small as they anticipated.

Power

Power Capacity:

The main reason the size of this Levin power bank is larger than other mini power banks is because it has higher power capacity. The higher the power capacity means either the charger will have more batteries or the batteries themselves will be larger. In this case, the battery is larger, and that is why the Levin portable charger has an initial power capacity of 5,000mAh. It won’t be losing too much power capacity during charging mainly because the charger only using a single Output charging port and also because it uses Panasonic battery cells. Panasonic battery cells are able to keep the conversion rate more stable during charging and that leads to more power being directed into the device that you’re charging.

As a result, you’re going to end up with an Output power capacity fo 4,200mAh. Even though this power capacity is higher than what other Mini chargers are offering, it’s still a power capacity that’s geared towards smaller devices like smartphones. Actually, you’re going to get the best experience with this portable charger for a smartphone because it can charge most smartphones 2-3 times.

It doesn’t make too much sense to charge tablets with this power bank. Charging Mini tablets like the iPad Mini 2 and 4 can take them to about 50% if you’re using the entire power capacity. However, charging full-sized tablets will result in them only being able to charge about 40% of the way through, so it’s best to stick to smaller devices with small batteries so you can make the most of the power bank.

Output Charging:

Charging speeds with these higher capacity mini power banks should always be faster because that’s the basic standard that they’re built up to. With that said, this is why the Levin charger has an Output charging speed of 5V/2.1A. This charging speed will be able to charge most smartphones that don’t use Quick Charge or USB-C at their fastest charging speeds. It won’t be able to charge tablets at their max charging speeds but it comes close with most tablet charging speeds being 2.4A.

It’s a pretty good charging speed because you’ll actually have your smartphone charging to a good amount of power within a reasonable amount of time that will allow you to be free from the power bank and just have your smartphone at a good power capacity.

The recharge rate is slower than the standard with these kinds of chargers because this one only has a max recharge rate of 5V/1.0A. So it doesn’t really matter what USB wall charger you’re using to recharge it because it’ll be able to recharge at a max charging rate with any wall charger that is 1 Amp or higher. With that said, you’re going to be waiting for about 3 – 3.5 hours for a full recharge.

Design

Size and Weight:

 

It can easily be held in a single or be placed into a back pocket or any bag or purse that you may be using. However, this isn’t as thin as other mini power banks, mainly due to its increased thickness.

Well, the length is really small at 3.5 inches, but the thickness of the power bank at 1 inch can make it difficult to place into a pocket. Also, it has a light weight at about 4.5 ounces.

Functional Components:

It’s an easy to use power bank, just as it should be. Although it’s just a bit different.

The power bank features a flashlight which isn’t very prevalent with too many other portable chargers that are designed the same way.

You can find nearly everything on the side of it where you’ll find the USB Output port, the Micro-USB Input, and the flashlight. The power button is basically on the same piece, and you’ll actually have to use the power button. Since charging doesn’t automatically start, you’ll have to use press the power button to begin charging.

To turn on the flashlight, you have to hold down the power button for about 3 seconds and to turn it off, you just hold it down for 3 seconds. When the power bank isn’t sending out a current, then it automatically turns off.

Build

Structure and Material:

It’s a strong power bank that can withstand a few falls. We say this because there are just 3 pieces that hold the charger together and all of it is made of Aluminum. Perfect for daily use and the fear of damaging it isn’t nearly as present as with other portable chargers.

Tech:

This Levin power bank does a great job at providing all the latest tech build with its safety features including things like Over-Charging Protection, Surge and Short-Circuit protection too; as well as many other safety techs features to keep your device and you safe during charging.

Also, the use of a Panasonic battery is what makes the Output power capacity so good, and the power bank will hold onto its quality in the long-term.

Reliability

Its reliability is highly standardized to whatever device you’re using it with mainly because it doesn’t do anything too special but this Levin charger gives out a great charging speed and enough power capacity to well with any smartphone on the market.

The build quality is strong and that means you can basically take it with you on your morning runs and not having to worry about dropping it; because it’s basically on the edge of being a rugged mini power bank.

Summary:

Power:

The Output power capacity is really good due to the usage of the Panasonic batteries, and that results in most smartphones being able to charge to their full power about twice. The Output charging is good enough to charge most devices at a reasonable and noticeable speed. The recharge could use some work as it’s only 1 Amp.

Design:

It’s small but not so small that it’s going to fit easily into your pocket, so it’s best to just hold it in your hands. You actually have to use the power button to begin charging and it’s also used to turn on the flashlight.

Build:

Most small chargers like these have a very strong build and the trend continues. The tech side is really good too because it makes use of lots of safety tech.

Reliability:

Most people will find this reliable if they’re searching for a small power bank that has a good charging speed and enough power capacity to last them 2 days of power.

However, if you want the fast charging for your USB-C or Quick Charge smartphone, then this isn’t it.

Conclusion:

The Levin is a great example of what a new generation of small but higher power capacity power banks is bringing with improvements in nearly all areas of quality, this charger does a great job at providing lots of power to give a reasonable charging or great charging experience to any USB charging device.

Review: AUKEY 5,000mAh USB-C Portable Charger

It’s not something that we expected to see for a while but here it is. A Mini power bank that makes use of a USB-C charging port for both Input and Output charging needs. Aukey is one of the first charging electronic companies to make this bold move and for really good reasons too. Since more smartphones are using USB-C for charging and it’s basically going to be the standard for most smartphones on the market, this power bank provides a dedicated way of charging using those devices without having any side things added on. It’s the minimalism behind this power bank is what will make it so spectacular.

This is Aukey’s 5,000mAh power bank with USB-C. Let’s see what it has to offer.

Power

Power Capacity:

The Aukey power bank is much like the newer generation of mini power banks because it offers an initial power capacity of 5,000mAh just like the Anker PowerCore 5000 and another one of Aukey’s 5,000mAh portable chargers. This one doesn’t make use of a special battery like LG or Pansonic and that doesn’t matter too much because the power bank only has a singular charging port, and as a result, on average you’ll be getting an Output power capacity of about 4,000mAh.

A 4,000mAh power capacity can actually get you quite far and it’s a really good thing that Aukey made their mini USB-C power bank have an initial power capacity of 5,000mAh and not a smaller power capacity like this Jackery power bank. This is because most smartphones that use USB-C have large battery capacities and that means that you’re going to need a lot of power to charge it to full.

Take for example these USB-C compatible smartphones:

  • One Plus 3:  3,000mAh
  • Google Pixel: 2,770mAh
  • Nexus 6P: 3,450mAh

Those are large battery capacities and this Aukey power bank is going to be able to charge all of those to their full power at least once. Some USB-C smartphones will be able to leave some power capacity behind too.

Also, even though this power bank uses a USB-C Output port, you can still charge smartphones like iPhones that use Lightning charging cables. However, you won’t be using a lightning charging cable, you’ll need a USB-C to USB Adapter.

Output Charging:

Just as USB-C charging should be, this power bank is able to provide a charging speed of 5V/3.0A, and that’s a max charging speed for most smartphones that use USB-C charging. Other than that, there’s not much to say about the charging speed, however, we’re surprised that a Mini power bank is able to Output such a fast speed and we hope to see other power banks have fast charged with their USB-A ports, just like this RAVPower Luster power bank does.

Overall, this Mini charger is able to provide max charging speed to USB-C compatible smartphones. With that said, though, if the smartphones are Quick Charge compatible then it’s not quite charging at its max charging speed because Quick Charge speeds are just a tad bit faster.

Input Charging:

The power bank is recharged by using the USB-C to USB-A charging cable and the max recharge rate is 5V/2.0A. We’re a bit disappointed since most power banks that use USB-C ports as an Input port have the max recharge rate at 3 Amps. Oh, well.

If you’re using a 2 Amp wall charger, then a full recharge will take 2-3 hours. So you’ll most likely be able to use it the same day that you used up all the power capacity.

Design

Size and Weight:

Most mini power banks are, well, “Mini”. Even though this portable charger is small, in terms of it being small in comparison to lower capacity power banks, it takes a rather larger stance.

This is because it has a length of 4.3 inches, and width/thickness of 1.1 inches. So it’s a small power bank, but not exactly on the thickness side and as a result it won’t be fitting into your pocket very comfortably. We’re not very surprised by that aspect because the Anker PowerCore 5000 and Aukey’s other small power bank have the same problem with being small but having too much bulge.

It’s very easy to hold the charger though with its small size and lightweight of 4.5 ounces.

Functional Components:

There are only 3 functional parts on this power bank and they can be found on the side. That’s where you’ll find the power button, 4 Green LED power capacity indicators and the USB-C charging port.

Charging automatically starts when connecting your charging cable, and that leaves the power button with the main function of simply checking power capacity.

Build

Structure and Material:

The Aukey power bank is made of plastic and it holds strong even though plastic is known be a brittle material. There are about 4 separate pieces that make the power bank whole and they do a good job at making the charger reliable to use on a daily basis.

Tech:

For a single port charger, it doesn’t have too many tech build benefits, but it does use safety tech that provides Over-Current, Overheating, and Overcharging protection so your smartphone stops charging once it’s fully recharged.

Reliability

Reliability is very narrow. This is because this power bank is really made for those that own USB-C compatible smartphones as they’ll be able to get the fastest charging speed and there’s no need for an adapter to charge other devices like iPhones. With that said, even though you can use the adapter with this power bank to charge different devices, it’s a hassle and it’s best to just stick to normal USB-A power banks if you’re searching for a power bank to either charge your Micro-USB or Lightning compatible device.

For those that do own a USB-C compatible smartphones, it’s going to be awesome to own this power bank as you’ll be able to get fast 3 Amp charging, enough power capacity to charge your smartphone once and superb portability.

Summary:

Power:

Charging is mainly meant for devices that use USB-C to charge as you’ll need a USB-C to USB-C charging cable. The power capacity is perfect for charging smartphones that it’s meant to charge.

Design:

It’s a small but bulky power bank that is very portable but it’s not meant to fit into your pocket. Charging automatically starts, and it only has 3 functional parts that make it easy to use.

Build:

A solid build and lots of safety tech to keep you and your devices safe during charging.

Reliability:

Most of the reliability is attributed to charging smartphones that use USB-C to charge; sure you can charge iPhones with it by using adapters but that’s a pretty big hassle.

Specs of the AUKEY 5,000mAh USB-C Portable Charger:

  • Capacity:            Advertised: 5,000mAh            Real Capacity: 4,000mAh
  • Output:  5V/3.0A
  • Input:      5V/2.0A
  • LED Power Indicators: 4 LED Dotted Power Capacity Indicators
  • Size: 6.2 x 2.6 x 1.1 inches
  • Weight: 4.5 Ounces

Conclusion:

For the most part, this power bank is great…. For USB-C smartphones users. It has all the aspects that a new generation of smartphones is bringing with its high enough power capacity, and fast charging; this power bank is built to withstand the test that newer smartphones are giving portable chargers with their rising needs.
