The design of the power bank itself is extremely simple, on the top you have the Aukey branding and a power button to turn on the power bank and also check how much battery life is left.

Unlike other power banks, the power button does have to be pressed to start delivering power to the devices, it cannot detect when a device has been plugged in and do automatic power delivery.

On the left-hand side, there are two output USB ports and also the ports to charge the power bank itself. What actually caught my attention with this power bank was the charging options The power bank can either be charged with a micro-USB cable or a Lightning cable, which is handy for iPhone users.

I would have liked to see USB-C as the charging choice for the power bank instead of the micro-USB port as USB-C can carry a lot more power and therefore, the power bank itself would be able to charge faster, but it isn’t a deal breaker at all.

The rest of the design is pretty plain, with only some information on battery specs on the bottom. There is also a battery indicator on the side.

The power bank isn’t exactly pocket-sized so that is something to bear in mind, but it’s still plenty small enough to chuck into a bag.


Charging devices is no problem thanks to the battery capacity of the power bank. Most phones will be able to get four full charges from the battery bank and it will even manage to fully charge an iPad Pro if you need to.

The power bank can also charge the standard size iPhone up to 7 times! This makes the battery bank great to take on a long trip with you or somewhere where you may not be able to easily find a plug socket.

One thing that you do have to take into consideration though is that the power bank itself will take quite a while to fully charge again since the battery size itself is so large. So you can expect to charge to take at least 5 hours or so to have it fully charged again – but I think that is acceptable for the amount of use that comes from it.


Overall, I think that the Aukey 20,000mAh power bank is a good product. It’s not perfect and there’s a couple of things that I’d like to see done differently but I like how it supports charging with a Lightning cable and how it does what it says on the tin, for a great price.
