The Anker 737 is one of the top choices for charging Steam Decks. It's a substantial power bank, with dimensions of 4.6"x2.2"x2" and a weight of 1.4lbs, making it ideal for travel bags or backpacks rather than pockets. It features two USB Type-C ports and one USB Type-A port, with the USB Type-C ports capable of delivering up to 140W of power. This allows for flexible charging options: one port can deliver 140W, or the ports can share the power, such as 70W + 70W or 100W + 40W, depending on the devices connected.

For gaming handhelds, the Steam Deck charges at up to 38W, the Asus ROG Ally at up to 65W, the Asus ROG Ally X at up to 100W, and the Nintendo Switch at up to 18W. The Anker 737 can charge all these devices at their maximum rates, allowing you to play and charge simultaneously without any issues.

With a 20,000mAh battery, equivalent to a 74Whr capacity, and an 80% power efficiency, you get about 59Whr of usable charge. This means the Anker 737 can fully charge a Steam Deck or Asus ROG Ally 1.5 times, an Asus ROG Ally X 0.75 times, and a Nintendo Switch about 3.7 times. This capacity underscores why a 20,000mAh power bank is essential for power-hungry devices like the Steam Deck and Asus ROG Ally, particularly the Ally X.

The Anker 737 is TSA-approved

The TSA approves power banks with capacities under 100Whr for carry-on luggage (check-in is not permitted). At 74Whr, the Anker 737 comfortably falls within these limits. While its size might attract additional checks, my personal experience traveling through various airports, including a single check at Tokyo NRT, confirms that it clears security without issues.
