The Anker 737 remains one of our top-rated Steam Deck chargers. This robust power bank measures 4.6"x2.2"x2" and weighs 1.4lbs, making it ideal for a travel bag or backpack rather than a pocket. It features two USB Type-C ports and one USB Type-A port. The USB-C ports support up to 140W of total Power Delivery output, which can be delivered through a single port or split across both, depending on the connected devices (e.g., 70W + 70W or 100W + 40W).

For gaming handhelds, charging capabilities vary: the Steam Deck supports 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 20W and 30W. The Anker's 140W output is sufficient to charge any of these devices while you play. It's also perfectly suited for the new 16-inch MacBook Pro, which accepts up to 140W.

The 24,000mAh capacity provides 89Wh of total energy. With a typical 80% power efficiency, you get about 71Wh of usable charge. This translates to approximately 1.8 full charges for a Steam Deck or Asus ROG Ally (40Wh), nearly one full charge for an Xbox Ally X (80Wh), and about 3.6 charges for a Nintendo Switch 2 (20Wh). This highlights why a 10,000mAh power bank is too small for power-hungry handhelds when even this 24,000mAh model can only fully recharge an Xbox Ally X once.
