Generic is really AUKEY |
Update: Sold out on Amazon. Check eBay.
A power bank is a big battery that can be used to power and recharge electronic devices when AC power is not available. Keep one charged to power phones in emergencies, when on an airplane without seat power, when camping or sailing, etc.
Unfortunately, they only last 3-5 years before losing so much capacity that they need to be recycled and replaced. Worse, it's hard to find a high-quality power back with good capacity, longevity and features at a good price.
At the moment, the best power bank for phones (not tablets or laptops) is the
AUKEY PB-N93A USB C Power Bank 20000mAh, PD Ultra Slim Power Bank with 18W PD. It has enough power for 3+ recharges of a typical smartphone and a wealth of good features. But the $60 price is too high for such a simple device that costs little to make.
There's a generic power bank on Amazon for only $16 that looks identical: PB-N93A USB C Power Bank 20000mAh, PD Ultra Slim Power Bank with 18W PD | Amazon.
The best part is that it's not just identical to the AUKEY, it is the AUKEY.
p.s. It can charge or power a device while itself recharging, so it can be used as a mini-UPS.
