The Baseus 20,800mAh 145W Power Bank Drops to $40 for Black Friday

The Baseus power bank has a 20,800mAh or 77Whr battery capacity. Factoring in a roughly 80% power efficiency rating (which is about standard for power banks), this power bank will charge a Steam Deck (40Whr) or Asus ROG Ally (40Whr) from empty to completely full 1.5 times, an Xbox Ally X (80Whr) 0.8 times, a Legion Go S (55Whr) about 1.1 times, and a Nintendo Switch or Switch 2 (20Whr) about 3 times. You can see why a smaller 10,000mAh power bank might be fine for the Switch but is insufficient for the more power hungry handheld gaming PCs.

The power bank is equipped with four ports: two USB Type-A ports that can deliver 33W each and two USB Type-C ports that can deliver 100W each. The power bank supports a total maximum output of 145W. So, for example, if you were using both USB-C ports, one port could deliver 100W and the other power would then be capped at 45W.

The 100W of maximum power output is more than enough for every handheld gaming PC released so far. The Steam Deck supports up to 45W of charging, the Asus ROG Ally up to 65W, the Xbox Ally X and Legion Go 2 up to 100W, and the Nintendo Switch and Switch 2 between 20W and 30W. You should be able to charge all of these gaming handhelds at their fastest rate while you’re playing games at the same time, even on Turbo settings.
