Review: RAVPower 27,000mAh AC Outlet Power Bank

pic-1

Here at Charger Harbor, we have plenty of reviews for high capacity portable chargers and it’s easy to know that when  a power bank has a high capacity, they’re able to offer more than just more power. In this case, there’s plenty of power capacity but there’s also an additional charging option and it’s called an AC Outlet. This is the same outlet that you can find in a wall outlet and it allows you to power devices that use a 2 prong plug.

These new kinds of high capacity power banks are paving the way for a truly ultimate charging experience that can be portable while providing an insane amount powering for many devices. Let’s take a look at what this AC power bank has to offer and if it’s above the usual high capacity power banks.

Power

Power Capacity:

First off, the power capacity of this power bank is 27,000mAh. It’s a lot of power but the actual power that you’re receiving can vary depending on the way you use it. The charger has plenty of charging options that go hand in hand with how much power capacity it can actually supply. With that said, the power bank can on average supply about 20,000mAh of true output capacity that you’ll be receiving. This is mostly due to the heat generated during charging, but you can expect an Output capacity to be lower or higher depending on your usage of the power bank.

So if you’re charging only a smartphone with power bank, then there’s a high chance that you’ll be able to use most of the 27,000mAh power capacity and as a result, you can charge a smartphone about 6 times or more with it. As for tablets, you can on average do full charges but it’s possible to charge more than 2 times with it depending on the other devices you’re charging.

It’s important to know that you can either use all 3 of the USB ports at the same time or you use the AC outlet. You cannot use all the USB charging ports AND the AC outlet at the same time. With that said, there’s still plenty of power to use it just comes with an equivalent exchange

USB Port charging: USB Type-C / Two iSmart USB Charging Output Ports

USB Type-C – 5V/3.0A

iSmart Charging Ports – 5V/2.4A

pic-1

Okay, so the traditional ways of charging are absolutely at the optimum level. The USB Type-C port is not an input, it’s actually an Output port only. To use the Type-C port as an Output port, you’ll have to use a Type-C to Type-C port to charge devices that accept Type-C for charging. It’s a very helpful port if you want to charge your Type-C compatible smartphones or you can use it to charge a new Macbook that accepts Type-C. The Type-C port is able to charge at 5V/3.0A, so it will charge your compatible devices near Quick Charge speed (Not quite there yet).

The other two charging ports are USB iSmart ports and are each capable of charging at 5V/2.4A, which is the max standard charging rate. Both of these of ports are great options for charging any USB charging device. These ports are able to charge a smartphone at its max speed (If they’re not Quick Charge compatible, Quick Charge compatible devices have their max charging speed with Quick Charge charging). Tablets like iPads can charge at their max speed as well because of the 2.4A of power delivery. Overall, you’ll be able to charge any of your USB devices quickly and plenty of power capacity to take advantage of the fast charging plenty of times.

AC Outlet

The next and most important aspect of this power bank is the AC Outlet that features two prongs to connect a device and use it. The AC outlet has a power supply of 100W. So it isn’t going to power a large full-size fridge or a large TV; instead, the AC Outlet is more geared towards providing power to smaller appliances like small vacuums, mini fridges, Laptop chargers or small fans. So, will it provide a great experience during power outages? Maybe, because it depends on how you’re using it and what you’re using it with. You can’t expect this power bank to supply a power to a really major appliance but you will be able to use your laptop for much long if your power does go out.

However, it’s not even about using this during a power outage. If you’re not near a wall outlet, and in most cases, that’s the scenario, then this power bank is an absolute savior.

Input Charging (Recharging): 19V/1.6A

Instead of the traditional the Micro-USB or Type-C recharge input port, this power bank opts for a different kind of conclusion by using a DC Input. The power bank charger comes with power adapter to charge the power bank and the recharge speed is 19V/1.6A. So it’s not charging at 2 or 3 Amps but that’s actually not such a bad thing when you consider the Voltage being at 19. This means that the power bank will recharge at a 1.6A current more constant and you can recharge the power bank full within 5-6 hours.

Design

Of course with a power bank with this high of a capacity and charging capabilities, you can expect this portable charger to be big and heavy. The length of the monstrous power bank is 6.8 inches, width is 5.3 inches and thickness of 1.6 inches. So it’s quite large but not so large that you can’t fit it into a single hand; what makes it seem large and cumbersome is the weight being 1.87 pounds. So it’s a very heavy power bank and it’s obviously not meant to be held and used, especially if you plan on charging more than one device.

pic-4

All the functional parts of the power bank are almost all in the same place. The USB Type-C, Two of the iSmart USB charging ports, power button and the AC Outlet are on the same side. You can access the AC Outlet by lifting up the flap that covers it. The DC Input is on the other side of the power bank. Then at the top of the power bank, is where there are 8 LED power indicators; it’s a great design choice to a better user experience because when you have much power capacity, 4 LEDs just won’t do it. By having 8 LED power indicators, it’s easier to know just how much power the power bank has left.

The power bank does not turn on automatically when you plug a device into it, so it’s vital to turn on the power bank to use it and to press the power button to turn it off if you’re not using it anymore; otherwise, the charger will stay on. Also, if you’re using the USB Ports once you’ve turned on the power bank and want to use the AC Outlet after a while, then you must turn off the power bank and turn it back on to use the AC Outlet.

Build

With its high capacity and many charging capabilities, the build of the power bank is alright. With something this big, we would have expected something with a more solid build but for now, the build is just okay.

The majority of the power bank is made of plastic and can feel quite low quality to hold. Even so, the material being made of plastic was more of a design choice so the high capacity power bank would be light. Light in comparison to being made of Aluminum or other materials. With that said, the power bank still holds strong but it’s simply the feeling that it’s made of second-rate materials is what makes it less desirable. We don’t recommend dropping it as a light kind of thing, since the weight of the charger is about 2 pounds; dropping the charger can most likely damage it because there will be a lot of shock generated on impact.

So, maybe the plastic material isn’t the best, but the functional components like the charging ports, power button, and the LED power indicators are built to very high standards. The ports are built to be used daily and don’t feel cheap, and the LED power indicators are accurate at telling the power capacity of the power bank.

If there’s one thing that can’t exactly be helped, it’s the heat generated during charging or usage of the power bank. Each one of the charging options and AC Outlet option is going to Output quite a lot of current or Watts in the case of the AC Outlet. As a result, the heat generated during charging cuts the power capacity quite a lot. You can’t expect the power capacity to be the 27,000mAh that’s advertised or even close to that capacity if you’re heavily using the power bank.

pic-3

With that in mind, the power bank still takes advantage of air vents, because it has an inner fan that is able to dissipate heat easily. The fan turns on periodically when you use the AC Outlet only, and it’s a great build feature, because as we mentioned before, the heat that’s generated can lead to too much lower Output capacity and can damage the power bank. The air vent is a must if the power bank wants to be fully and safely used.

Reliability

Of course, a power bank of its caliber is reliable. From the very high power capacity to the options of charging, and AC power outlet; this power bank just might be as reliable as it can get. Power can last for days or even a week if you’re using it in moderation. You’ll be able to charge 3 devices at once with the two USB charging ports and 1 USB Type-C port, or you can opt for using the AC Outlet to use compatible appliances with power to match at 100 Watts. This is a great portable charger to take with you and use if you’re going to be away from a stable source of power. We found that it’s not just for power outages situations, it can be used to power devices close to using as a way of convenience.

However, for more free portable reasons the power bank doesn’t do so well. You can’t take this power bank for a walk simply because it’s so heavy and large. It’s not the kind of “Portable” charger that you can pick up and go with, instead, you’re going to have to use it as a charging hub almost always. Also, if you’re not going to be taking full advantage of the powering options that this charger has to offer, then maybe it’s best to look for something else. This is because the power bank has so many capabilities, but if you’re not using most or all of them, then you’re not getting your moneys worth for what you paid for.

Summary:

Power

power

This is where the power bank excels the most even though the 27,000mAh capacity isn’t exactly what you’ll be getting, because of power lost during charging. But we will say that the Power capacity you will be receiving will last for a long time and will be able to charge nearly any device that you have plenty of times. The charging speed for the USB charging ports are basically at the optimum speed and you can charge 3 devices at the same time. The most important aspect of the high capacity power bank is the AC Outlet; with it, you can power devices that are powered up to 100Watts. So you can use it to charge devices like Laptops. The biggest hindrance, though, is that you can either use the AC Outlet only or the 3 USB charging ports only.

Design

design

With its high capacity and many charging options, of course, this power bank is going to be large and heavy. Weighing about 2 pounds and with big dimensions, it’s not the kind of portable charger that you’d hold and use. Instead, we think the best way to describe this power bank is as a Station charger. It’s most likely that you’ll be using it by setting it down, and this will be especially true if you’re using the AC Outlet. All the functional components are easy to find and the addition of many LED lights are great for pinpointing power capacity left in it.

Build

build

It’s mostly made of plastic and doesn’t feel very strong but it’s light as a result of using plastic. The functional parts feel great  and are meant to be used daily. The most noticeable build feature is the vent in the charger. It has a fan inside that turns on periodically to dissipate heat when you use the AC Outlet.

Reliability

reliability

It’s a very reliable power bank if you’re using the AC Outlet and the USB charging ports. Along with the high power capacity, it’ll give you faster long lasting charging before needing a recharge. When the power bank does need a recharge, it uses a DC Input for faster recharging than the traditional Micro-USB input charging; but the only the setback is that you won’t be able to rely on the many Micro-USB cables that you may have lying around.

Overall, the power bank is reliable to the limit, but if you’re not using it to its limit or near the limit, then there’s really not much to rely on and as a result, there’s not much reason to own it.

Specs of the RAVPower 27,000mAh AC Outlet Power Bank:

  • Capacity:            Advertised: 27,000mAh             Real Capacity: 20,000-24,0000mAh
  • Output:

  • LED Power Indicators: 8 LED Power Capactiy Indicators
  • Size: 5.5 x 6.7 x 1.6 inches
  • Weight: 1.87 Pounds

Conclusion:

This thing isn’t the only power bank to be capable of delivering such a powerful charging experience. The power capacity is high enough to last you a really long time, we’re talking days or weeks and no less than that; unless you’re using the AC Outlet to its limit. The AC outlet is the main attraction for this beast, as it power devices up to 100Watts of power. It’s got the safety capabilities to keep the charging experience safe, although the power capacity can fluctuate depending on the way you’re using it. However, to get the most out of this very capable power bank, you’re going to need to use most of its features. Mostly because the price you pay to get it, is more of an investment rather than a purchase.

Review: ChargeTech – 27,000mAh Portable AC Battery Pack

pic-10

AC Outlet power banks is a growing way to not only charge devices but it’s a great way to power devices as well. These kind of chargers are able to be more than just being able to provide charging power to your smartphone or tablet. Instead, they’re also able to act as a portable wall outlet with their built-in AC outlets. With this kind of tech, the freedom of taking your laptop and sitting freely anywhere in the library or perhaps taking it camping is where this kind of charger performs best. There’s such a need for this kind power, and when we don’t have it, it can make our experiences fall short of greatness.

This is the ChargeTech 27,000mAh portable power bank. It has quite a bit to boast about, but let’s find out if it’s all not just a bluff.

Power

pic-5

Power Capacity:

The power capacity is 27,000mAh and with Panasonic batteries being used, we’re actually really confident that you’re going to be receiving close to that power. The charging speed you receive for the device you’re charging will clearly determine the real power capacity that you’re able to get. With that said, though the charging speed out of the two USB Ports is combined to be only 2.4A, and AC Outlet is able to Output or rather power 85W. So if you’re charging from either USB port, it won’t do much to the power capacity, because the Amperage current will only be at a possible max of 2.4A and that will not generate too much heat to provide poor conversion rate. Altogether if considering the usage of the USB ports and the AC Outlet at the same time, the Output power capacity that you’d be receiving would be 24,000mAh. Of course, that’s still a rough estimate because it will wholly depend on your usage of the power bank.

With that said, the power capacity from using the USB ports should provide you with enough power capacity to charge smartphones 5 times or more; plenty more times if you have a smartphone with a small battery capacity. Tablets can charge about 2 times, but that’s usually the case if you’re taking advantage of the entire power capacity.

AC Outlet: 3 Prong Outlet

pic-9

It’s basically like taking a wall outlet with you on the go. This AC Outlet can take a 3 prong plug, so you can use either or 3 prong devices or 2 prong ones to use with the outlet. Although that’s true only if the power bank is able to power the device you’re connecting it to. The main thing to consider is the AC Outlet’s power delivery and how much Watts the device that you’re connecting the power bank to requires in order function. To give you a general idea, 85Watts is going to be able to power small appliances like small fans, hair straighteners, a videogame console like the Wii or Xbox One and a Laptop charger being the most used device to use with the AC outlet.

So it’s important to know what devices you want to use with AC Outlet and more importantly whether or not they are being powered at 85 watts or lower. Anything over 85W and the AC Outlet will be rendered useless.

Two USB Outputs: Max Output 5V/2.4A

There are two USB charging Output ports with this power bank and it sounds really good but unfortunately, the max Output of both of the ports combined is 5V/2.4A. Don’t be fooled by what ChargeTech has written on their website or the Amazon page. The charging output is shared between both of the USB ports, so if you plug a tablet into one port and a smartphone into the other port, the tablet will not be charging at its max speed since power is being pulled to the smartphone as well. If you want to charge a tablet like an iPad at max speed, then we recommend charging the iPad alone; this way, the iPad will be able to draw the full 2.4 Amp current.

If you’re charging two smartphones using the USB ports, then you can most likely expect both of the smartphones take 1.0A or 1.2A to be more precise. However, it’s best to connect just a single phone even in this case because most smartphones nowadays can charge beyond 1.0A charging speed.

Input Charging: 20V/2A

The power bank doesn’t use the traditional Micro-USB Input port to recharge, instead, you have to charge it with a DC power cord that comes with the power bank charger. So even though the recharging can’t be done using a Micro-USB cable that is rather universal and you can easily get one nearly anywhere; charging with the DC cord is an overall much better way to recharge the power bank.

This is because the Input is at 20V/2A. This charging is great because the high voltage ensures that the Amp current is almost always constant during the recharging process and as a result, you can expect the power bank to be fully recharged in 2.5 hours. For a power bank with 27,000mAh of power capacity, this type of charging is very welcomed.

Design

With its power capabilities, of course, this AC power bank it going to be large and quite heavy. The length of the ChargeTech power bank is 7.5 inches, 5.2 inches in width and 1 inch in thickness. So it’s basically the size of a tablet in terms of length and width. It’s on the heavy side at a weight of 2.4 pounds. So to be clear if you haven’t gotten the idea yet. This power bank is NOT meant to be held and used. You’re mainly supposed to set it down and use it. This goes for charging a smartphone, tablet and especially if you’re using the AC Outlet.

If you’re taking it somewhere, you could just hold it on your way to your location or put it into a bag for more convenience. Even though the charger is large and heavy, it’s your best bet to be able to get really portable power through an AC outlet in a comfortable location. The main purpose for this charger being made was so that you don’t have to be stuck to wall outlets. It solves the problem by practically making this a portable wall outlet (Only if you’re charging a device that can draw 85Watts or less!).

The functional parts of the AC power bank are mostly on a single side. One side of the charger has the 3 prong AC Outlet, a light to indicate the AC outlet is on, a switch to turn on the AC Outlet and 2 USB charging ports. On top is the power button and 4 LED power capacity indicators.

pic-1

This power bank must be turned on in order to begin charging and you can press the power button to turn it on. Once on, the USB charging ports illuminate a blue color within them regardless of them having a cable inside them or not. The charger does not stop charging once a device has charged fully through the USB ports, so if you want to save power capacity you have to remove the device from the USB port. This kind of design somewhat shows the power bank’s age and how it should really implement Over-Charging Protection because this way more power capacity would be saved.

You have to turn on the AC Outlet in order to use it and we find this to be a good idea since it would dangerous to have the AC outlet on at all times. To turn on the AC Outlet, you simply switch it to “On” and then a Red vertical light comes on next to the AC outlet to show that it’s ready to use.

Putting it all together, this isn’t exactly a “Portable power bank” in the way that many power bank chargers are. Don’t get us wrong, though, of course, this is meant to be portable; just not portable as in walking around with it freely. It has a pretty good design, just needs an auto-off feature so there’s no worry about turning it off manually.

Build

This large and heavy power bank has quite a few separated parts and it’s all made of plastic. Although it’s all really solid. There aren’t any parts that are able to come loose and all the functional parts of the charger are depressed into the power bank so nothing is sticking out. Of course just a bit of a warning, though; dropping the power bank is not something that should be taken lightly. When you have something as heavy as this (at 2.4 pounds) then something inside or outside of it is bound to get damaged because the shock from the heavy weight will damage it. It may look physically tough, but it’s not a rugged power bank built like RAVPower’s Rugged charger or EasyAcc’s.

On the inside is where there are a few issues. ChargeTech hasn’t disclosed what kind of safety tech they have implemented with this AC power bank, but we’re pretty sure that there’s the usual Short-Circuit Prevention and Current Control; otherwise, the power bank would be really damaged after a few uses. Of course, there’s the use of Panasonic cells that make the conversion quite good and the batteries are able to last for more charge cycles.

With that said, the charger can heat up if it’s being used heavily and as a result, you’ll be getting less Output power capacity.

Reliability

pic-4

This power bank is highly reliable if you’re mainly purchasing it to use the AC Outlet. It’s a harsh thing to say but that’s really the truth. Sure, the charger does have 2 USB charging ports but the Max Output of both USB ports put together is only 2.4A and that’s not very much power if you’re charging two devices at the same time. Some might say that the power capacity is a lot and that’s true. The power capacity can very well last you days or even weeks but the charging speed that you’re receiving right then and there matters a lot too.

Also, you must use a device that is only able to draw 85Watts or less when you’re using the AC Outlet. Anything that needs more power is going to make the AC Outlet useless. So you should know what you’re going to use with this AC outlet that this power bank has, as a way of ensuring that you’re actually able to use the charger’s main feature. It may be described as a portable wall outlet, which is true to an extent but it’s not of the same powering capabilities.

power

The power capacity is really impressive at an approximately 24,000mAh Output power that can last for days or even weeks. The USB charging is disappointing and will only be able to provide 2.4A Max Output. The AC Outlet is able to take either 2 or 3 prong plugs, but can only power devices up to 85W or lower.

design

It’s about the size of a tablet and is heavy at 2.4 pounds. To put it simply, you gotta put this thing down to charge comfortably. The lack of the USB port’s ability to stop charging when a device is fully charged is obsolete. The power bank must be turned on to use the USB ports and once on, the AC Outlet must be turned on via a switch. The USB ports have a blue light that’s illuminated inside of them and the AC Outlet has a Red light next to it to indicate that it’s on.

build

The power bank is separated into quite a few pieces that are all made of plastic. However it holds strong, but just don’t drop it because the amount of shock may very well damage the power bank. The use of Panasonic battery cells is welcome as it provides a better conversion rating and longer lasting batteries. The charger does heat up if you’re using it heavily with the AC Outlet and the USB charging ports together.

reliability

It’s at its most reliable when you’re using the AC Outlet. You can use the USB charging ports but that’s not really the main thing that this power bank is able to provide. The main thing is to use the AC Outlet with a device that can be powered from it. If you’re only using the USB charging ports, then you’re only relying on half the capabilities.

Specs of the ChargeTech – 27,000mAh Portable AC Battery Pack:

  • Capacity:            Advertised: 27,000mAh            Real Capacity: 24,000mAhmAh
  • Output:      USB Charging Ports Max Output: 5V/2.4         AC Outlet: 85 Watts
  • Input: 20V/2A via DC Cord
  • LED Power Indicators: 4 LED Power Capacity Indicators
  • Size: 7.5 x 5.2 x 1 inches
  • Weight: 2.4 Pounds

Conclusion:

Power banks with AC Outlets are good but they’re not the best in terms of what you’d think they’d provide. Sure, they have an AC Outlet but the main mistake is thinking that the AC Outlet has the same powering capabilities as a wall outlet, but it doesn’t. In this case, the ChargeTech AC Outlet power bank does a good job with providing just enough power through its USB charging ports and a good amount of power through its AC Outlet of 85Watts to provide for your needs. You can’t go over board with it but it’ll do just fine if you know how and what you want to use it with.
