Baseus 20,800mAh, 145W Power Bank for $45
The Baseus power bank has a battery capacity of 20,800 mAh or 77 Wh. Given an energy efficiency rating of approximately 80% (which is about standard for power supplies), this power supply will charge a Steam Deck (40Wh) or Asus ROG Ally (40Wh) from empty to fully charged. 1.5 timesXbox Ally X (80 Wh) 0.8 timesLegion Go S (55 Wh) approx. 1.1 timesand Nintendo Switch or Switch 2 (20 Wh) approx. 3 times. You can see why a smaller 10,000mAh power supply might be fine for the Switch, but not sufficient for more power-hungry portable gaming PCs.
The power supply is equipped with four ports: two USB Type-A ports with a power of 33 W each and two USB Type-C ports with a power of 100 W each. The power supply supports a total maximum power of 145W. So, for example, if you use both USB-C ports, one port might output 100W of power while the other would be limited to 45W.
The maximum output power of 100W is more than enough for every portable gaming PC released so far. The Steam Deck supports charging up to 45W, 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 20 and 30W. You will be able to charge all these gaming laptops at top speeds while playing games at the same time, even on Turbo mode.
