Awei P37K 10000mAh 2.1A Fast Charging Power Bank

The 10000mAh bank in Awei's range that delivers the most actual charge, which is not the same thing as the highest headline number. Compare it across our power banks.

6200mAh delivered is the figure worth comparing

Every power bank loses energy converting the cell's 3.7 volts up to the 5 volts USB needs. What survives that conversion is the rated output, and it is the only figure that tells you how much charge your phone will actually receive. The P37K quotes 6200mAh from a nominal 10000mAh cell — about 62 per cent. The P20K, with the same nominal capacity, quotes 5200mAh. That is a full thousand milliamp-hours more from the P37K, or roughly a quarter of an extra phone charge, for the same stated size. Most brands never publish this number at all, which is precisely why it is worth reading when they do.

Two independent outputs

Both USB-A ports run at DC 5V/2.1A and are independent, meaning charging a second device does not slow the first. That is a real distinction from banks that share one power budget across two sockets and quietly halve both.

Recharging and indication

Type-C and Micro USB inputs at 5V/2.1A, so any cable you own will do. LED indicators show remaining level in steps rather than as a percentage — if you want an exact figure, the P32K has a digital readout.
