There are lots of portable chargers on the market and you probably know this with all the reviews that we’ve done on them.

So you probably already know that there are small ones that don’t have much-charging features, or how there are ones that are small and yet they have some unique and powerful charging features. Just like Aukey’s 5,000mAh USB-C power bank.

In this case, Aukey has created a very high capacity power bank that other companies have also created, such as Kisreal.

With that said, this portable charger is coming from a flagship charging electronic brand and that means quite a lot. The reason for that is because there’s clearly a value for these types of chargers and that’s why we’re doing a review for it.

It not only has a high power capacity, but it also has a lot of charging going on with its USB ports and the form factor is surprisingly small considering its powering capabilities.


Power Capacity:

There’s a lot of power to be used with this Aukey power bank, as it has a 26,800mAh power capacity that you’re going to be able to charge your devices with to full power multiples times.

Even after its conversion, the power capacity of this charger is still going to be quite plentiful as the higher base capacity you have, will result in a higher output capacity.

3.7 x 26,800 = 99,160 / 5 = 19,832

So after its conversion of power, you’re actually going to be able to utilize a 19,832mAh capacity to charge your smartphone, tablets and other USB chargeable devices. Smartphones are going to have the most charges, no matter what phone your charging you’re able to get at least 5 full charges for that phone.

Charging tablets will also provide another great experience as you can get 4 full charges or maybe, even more, depending on what tablet you’re charging.

Using this power bank moderately will likely result in not having to recharge it for about a week. Overall, it’s a perfect power bank to get if you’re going to be away from a stable source of power for quite a while.

Then there’s the charging experience that you’re able to get from the output ports.

Output Charging:

There are a total of four output charging ports to charge your devices with. There are three USB-A charging ports and the fourth output is a USB-C port.

Two USB-A charging ports have a charging speed of 5V/3.0A which is faster than the standard max charging rate of 2.4 Amps.

Then the third USB-A port has a charging speed of 5V/2.4A. Even though there’s no Quick Charge on this power bank, it doesn’t pose too much of a problem as the three USB-A charging ports still supply a very high standard charging rate that is able to charge most devices that are even Quick Charge compatible very quickly.

Tablets such as iPads are able to charge at their max charging with this power bank as it has two 3 Amp ports and one 2.4 Amp port.

The fourth and final output is the USB-C port. To use it as an output you must use a USB-C to USB-C charging cable, and therefore you can charge USB-C compatible devices with it.

Or you can use a USB-C to Lighting cable to charge your iPhone 8 or iPhone X at a faster charging speed. The USB-C port on this 26,800mAh power bank is 5V/3.0A which is basically the standard with most power banks that use USB-C.

Input Charging:

There are a total three input ports for recharging this very high capacity Aukey power bank.

However, the first thing that you need to know is that they can only be used once at a time, and we think that Aukey should have at least made it so that you could use two at the same time as this power bank has a 26,800mAh power capacity.

There’s a Micro-USB input which most power banks use and it has a 5V/2.0A recharge rate.

Then there’s the Lightning input that has a 5V/1.5A recharge speed and the last input port is the USB-C port which has a recharge speed of 5V/3.0A. So you should definitely use the USB-C port for recharging this power bank as it has the fastest recharging speed.

Another thing to know is that you should use a 2.4 Amp or Quick Charge USB wall charger when it does come to recharging this power bank as it’ll offer the fastest recharge rate for each of the ports. Even though the USB-C port has the fastest charging speed, the fact that there are three ways to recharge simply makes this power bank a whole lot reliable.

Size and Weight:

The power of this charger is the main part of this power bank. However, the portability that goes with it is just as important as the main reason to get a power bank is to be portable with it. This charger has a long length of 7.8 inches, a width of 3.7 inches, and a thickness of 0.7 inches. The weight of it is 1.3 pounds.

Of course, we won’t deny that this charger isn’t lightweight, as it’s quite heavy actually.

That said, the form factor of this high capacity power bank is actually very small and with its slimness, you’re actually able to hold this easier than most other high capacity power banks that have larger/bulkier form factors. At least you can slide this into a backpack a lot easier and it won’t take up too much space.

Functional Components:

A few of the functional parts of the power bank are on different sides, but they’re very close together and this charger is still easy to use.

It has its three USB-A ports, the USB-C port and Lightning port on one side. Then the Micro-USB input port is alone on one long side of the charger. Then on the opposite side from where the Micro-USB input is, is where you can find the power button and four LED power capacity indicators.

You do have to press the power button to begin charging no matter what port you’re using. The beauty of the functional component placement is that this charger has everything on the slim sides and nothing at the top or bottom of the power bank.


Structure and Material:

The entire power bank is made of plastic, but that’s standard with most portable chargers and we think it’s a good build choice as using a material such as Aluminum will make this charger heavier.

There are a total of three parts that make this power bank whole and that would be the top, bottom, and middle pieces.

It’s not a shock-resistant power bank but it definitely has a good structure and the functional parts of this charger such as the USB ports feel great to use, the LED lights are dim but noticeable and the power button is nice to press.


Since there are so many USB charging ports to use at the same time you might think that it’s unsafe to charge lots of devices at once with the power bank. That said, it’s not true at all as this charger only gets slightly warm if you’re using all four of its output ports at the same time.


There’s a lot of reliability to be had with this power bank, from its high power capacity that can charge a small device such as smartphones and larger devices such as tablets to full power multiple times over.

From its many charging ports with its four output ports and also its use of three input ports which makes recharging this power bank more convenient as you can use one of three charging cables to recharge it.

Portability with most high capacity power banks isn’t the best, but Aukey found a good solution to making portability at least bearable and that’s by making this charger have a slim form factor.

The power capacity of this charger is plentiful and is able to charge lots of devices to full power many times. Also, it has lots of charging ports for output and input too.


Most high capacity power banks are large and bulky, this one at least takes a slim approach.


The build quality of this charger is top notch with its use of only three separate pieces that make it whole. Another part that makes the build quality good is that it doesn’t overheat even when you’re charging lots of devices at once.


Reliability for this power bank is very good with all of its parts put together from its powering abilities to its slim form factor.
