Aukey 20000mAh Power Bank Review

Looking for a high capacity charger that lives up to its charging claims? The Aukey 20000mAh Power Bank might just be the charger for you. With dual USB inputs, a solid, neat design and a whopping 20000mAh, it’s certainly priced amazingly too. So is it perfect? We wish it was, however, you must take the good with the bad. The story continues below!

Capacity & charging speed

I’d like to start off by congratulating Aukey. The Aukey 20000mAh Power Bank tested superbly and gave about 90% efficiency of its battery capacity. This is rare with any battery and more often than not, you can expect less than 80% of the manufacturers mAh rating. To me, this indicates that Aukey has potentially rammed a higher capacity battery inside, tested it and given it an appropriate mAh closer to its real output.

With a big battery comes long charge times, expect to wait between 10-16 hours for the portable charger to fully juice up. This is not out of the ordinary but can be inconvenient for some. The 2 USB ports are rated at 2.4A and 1A respectively. I always love to see both ports pushing 2.1A on dual USB devices and having 2 speeds is generally to keep component costs down. Cost-cutting exercises can be done to pass onto the consumer, but can also mean defective equipment in a high percentage of units. We’ll get to that later.

Look and feel

I quite like the look of the Aukey 20000mAh Power Bank. It’s a nice shape and looks quite modern. There are 2 USB slots on the short edge of the unit, separated by a flashlight. The speed of the ports is denoted by 1 lightning icon for the 1A output and 2 lightning icons for the 2.1A.

The power button which controls the flashlight as well sits between 4 LED battery indicators. The micro USB slot sits close to the edge of the unit on the rounded length of the power bank. Take note, however, the Aukey 20000mAh Power Bank comes with only one Micro USB cable so you may have to purchase another if you don’t already have a high-quality cable handy.

Durability & construction

This is possibly where Aukey could work a little harder. There have been an unusually large amount of product defects shipped from the factory. Whether this is due to cheaping out on components, circuitry or whether it’s a firmware issue is yet to be decided. Some people have commented that their Aukey 20000mAh power bank only lasted them a month. The happy customers have been using theirs for incredibly long periods of time with no battery loss whatsoever.

Portability

The Aukey 20000mAh Power Bank is definitely not a pocket device. I would certainly call it portable though. For the suspected mAh of this unit, it’s clear that Aukey has taken pains to keep the size down. It’s relatively light and a fair bit smaller than something like the RAVPower 22000mAh Power bank.

It’s important to note however that the RAVPower unit has 3 USB ports and is actually a little thinner and lighter than the Aukey. All in all the Aukey 20000mAh gets points for portability as we suspect it’s packing some extra unexpected battery power in there that’s not on the box.
