  • Even though it's small, it has enough power capacity to charge some smartphones 2 times. Most will be able to charge once.
  • It's very small, and it can fit into a pocket quite easily. If not, then it's really easy to hold.
  • Faster charging than most small power banks with a Output of 2.1A.


  • Small power capacity, don't expect it to charge a tablet fully or last for a few days.
  • Conversion Rate could be improved

Small power banks with the ability to take our portable powering solutions with us on the go are amazing to have and use.

Sure, a power bank is ultimately supposed to hold the ability to allow us to take them anywhere, but it’s the portable chargers that are smaller than the usual standard that makes taking them anywhere very easy.

These chargers may sometimes lack the tech that other higher capacity and the bigger portable charger might have but these power banks are still very capable of providing tons of value.

This is the 5,000mAh Aukey Pocket charger.

Power Capacity

Of course, this being a small portable charger the power capacity isn’t going to be that much.

The initial power capacity that you will be getting is 5,000mAh and with the power bank only having a single charging port, you won’t be losing much.

Even though it depends on the charging speed you’ll be getting, on average you’re going to be receiving about 4,000mAh of Output capacity.

4,000mAh of Output isn’t that bad for a charger of its size and you can expect to get full charges for nearly any smartphones that you have, this even goes for smartphones that have very large battery capacities like the Samsung Galaxy S7 Edge with its 3,600mAh power capacity.

So this charger is mainly meant to be used for small devices with small battery capacities and you can even get more power even after charging your smartphone to its full capacity.

As for tablets, this power bank isn’t designed with the tablet in mind. And if you were to use a tablet like an iPad with this power bank, then it wouldn’t be so good.

Even with the lowest grade iPad with the lowest battery capacity, the power capacity of the power bank will only be able to charge it a quarter of the way through or maybe halfway.

Output Charging: 5V/2.1A

The Output speed is good at 2.1 Amps which is close to the Max Standard charging rate of 2.4 Amps.

As a result, this charger will be able to charge nearly any devices that are connected to it at its max charging speed. This goes for most smartphones, except for smartphones that use Quick Charge because this power bank does not feature Quick Charge tech.

We’re even talking about tablets too since many tablets like iPads have a max recharge rate of 5V/2.4A, this power bank does a good job at recharging them near their max charging speed.

We’re really surprised that this power bank can Output so much Amperage from such a small device.

Input Charging: 5V/2.1A

The Input charging is equivalent to the Output charging and as a result, as long as you’re using a 2.1A wall charger with this power bank or a higher Amperage wall charger to recharge it, then it will recharge within 3-4 hours.

If you’re using a 1 Amp wall charger then recharge times will be around 5-6 hours.

So it’s important to know what wall chargers you should be used with this power bank so you can recharge it as fast as possible.

Size and Weight:

Of course, the size and weight of the charger aren’t that large.

The length is 3.5 inches, the width is 1.7 inches and the thickness is 0.9 inches. It’s also a lightweight power bank that weighs 4 ounces.

Overall, it is indeed a power bank that is small and lightweight enough to fit into your pocket. Or if you don’t want to place it into your pocket because the thickness may be too great for comfort, then holding this portable charger will hold no problems.

Functional Components:


One of the best parts of this power bank is the way that you use it. It’s really simple

The USB output port and the Input Micro-USB port are on a side panel of the charger. There are a power button and 4 Blue LED Power capacity indicators on tap of the power bank.

The power button is not used very much unless you want to check the power capacity of the power bank by simply tapping it.

Other than that, the power button holds no other functions as charging begins automatically when you connect a device to it, and charging stops when there are no devices connected to it or when the device it’s charging is at full.

Very well Lit Power Indicators


The most noticeable thing about the design is the 4 LED power capacity indicators because they’re a lot more noticeable than the usually dotted power capacity indicators on most power banks. These are larger and bright blue.

Structure and Material:

There’s nothing special about the physical build of the power bank because it’s just made of plastic and 3 parts are holding it together. However, that’s not to say that the build isn’t good.

It’s good with the pieces being well placed and holding real tight.

Also, since the weight of the charger isn’t too heavy, we think that it can take shock damage quite well. Just don’t go throwing it or dropping it on purpose.


Just like the structure, the tech build side of things is very usual. There’s the usual safety tech to keep you and your devices safe and that’s about it.

The power bank doesn’t take advantage of any special batteries like Panasonic battery cells but it does a good job even without those.

It’s a reliable power bank and that can’t be said about many other small portables chargers because they’re usually just small and provide too little in the way of powering capabilities.

In this case, the Aukey 5,000mAh power bank can provide a reliable amount of power capacity that can charge most smartphones once while still having some power capacity left over.

The charging speeds are very effective no matter what you’re charging because both of them are capable of Outputting 2.1A, which is very uncommon for a power bank of its size to do.

Aukey 5,000mAh USB-C Power Bank



The power capacity has the usual conversion rate that makes the Output capacity 4,000mAh but that’s still enough to charge most smartphones to their full capacity and even leave some more power.

The charging speed is good with the Output and Input being 2.1A.


It’s a small and light portable power bank that can fit into your pocket or you just hold it and use your smartphone while it’s charging from the power bank.


There’s nothing special about the build but it does a good job. The structure is held strong and the lightweight of it gives it less of a chance that it will get damaged from a fall.


It’s reliable for a small power bank and optimizes itself to provide the most that it can out of its small size.

Specs of the Aukey Pocket 5,000mAh Power Bank:

  • Capacity: 5,000mAh
  • Output:   Max Output: 5V/2.1A

  • LED Power Indicators: 4 LED Dotted Power Capacity Indicators

  • Weight: 4 Ounces


Most small power banks take the easy way out by giving in to their limitations. This means that they have slower charging speeds and lower power capacities.

In this case, though, Aukey 5,000mAh provides enough power capacity to charge plenty of smartphones to their full capacities and a charging speed of 2.1A that not many other chargers have.

Other power banks are starting to meet this standard and we think that this is a great thing for the portable charging market because it’s providing more quality.
