Awei P78K 20000mAh 22.5W Transparent Fast Charge Power Bank

Awei P78K 20000mAh 22.5W Transparent Fast Charge Power Bank

Magnetic wireless charging at 20000mAh, in a transparent shell that shows the cells doing the work. Compare it across our power banks.

Magnetic charging at a capacity that supports it

Wireless charging is convenient and inefficient — energy is lost as heat crossing the gap between the coils, so you get meaningfully fewer charges than the same bank delivers over a cable. On a 10000mAh bank that loss hurts, because you may only get one wireless phone charge out of it. At 20000mAh there is enough headroom that the convenience stops costing you the use of the bank. If you want the magnetic experience without watching the battery meter, this is the capacity to do it at — the P52K is the same idea at half the size.

Wired fast charging and connections

Power Delivery at 22.5W handles the wired side, which is genuine fast-charge speed rather than standard USB output. Type-C and Lightning connections are both provided. As with every magnetic bank, the magnets grip MagSafe-compatible iPhones directly; Android phones need a magnetic ring or a case with one built in.

The transparent shell

It is a styling choice, and an honest one — you can see the cells and the board rather than a moulded plastic box. Practically it changes nothing, though clear plastic shows scratches a little more readily than a coloured finish, which is worth knowing if it lives loose in a bag.
