Last Chance to Get the Baseus 20,000mAh 140W Power Bank for Just $29.99 During Prime Day

This Baseus power bank features a spacious 20,000mAh or 74Whr battery capacity. Factoring in a roughly 80% power efficiency rating, this power bank will charge a Steam Deck (40Whr) or Asus ROG Ally (40Whr) from empty to completely full about 1.5 times, an Xbox Ally X (80Whr) 0.7 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 100W USB-C ports, one retractable 100W USB-C cable, and one USB-A port. Note that although the total maximum output is 145W, the maximum output of each USB-C port is 100W. For laptops that can accept 140W of charging like the MacBook Pro, you would have to dual charge with two USB cables.

Details

That said, 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 X20, 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 even while you're playing games simultaneously.
