Awei PA-37 22.5W PD Fast Charging Digital Power Bank 20000mAh

Awei PA-37 22.5W PD Fast Charging Digital Power Bank 20000mAh

The middle size in Awei's PA line, and for most people the one that makes sense. Compare it across our power banks.

Why 20000mAh is the sensible default

Ten thousand covers a long day. Thirty thousand covers a week but weighs enough that you notice it and pushes you over the airline threshold. Twenty thousand sits in between: three or four full phone charges, still comfortably under the 100Wh limit airlines apply without prior approval, and light enough to travel with. It is the capacity that solves the actual problem most people have, which is a weekend or a long journey rather than a fortnight off-grid.

Fast charging and the display

Power Delivery at 22.5W, which is roughly double standard USB speed on a phone that supports it. The digital percentage readout replaces the guesswork of three or four LEDs — with dots, one lit could mean a quarter full or nearly empty, and you find out at the worst moment. A number also lets you confirm the bank is actually charging when you plug it in.

How it compares to the Baseus Comet

Worth a direct look. The Baseus Comet is also 20000mAh at 22.5W with a display, and adds two built-in cables so you need carry nothing else. It also publishes its rated deliverable output, which Awei does not. Against that, the Awei carries a longer warranty term — both are in the specification tables, and they differ.

Expect roughly sixty to seventy per cent of the nominal figure to reach your devices. At about 74 watt-hours it flies without approval, in cabin baggage only.
