The Anker 737 stands out as one of the best options for charging the Steam Deck. This power bank is on the larger side, with dimensions of 4.6"x2.2"x2" and a weight of 1.4lbs, making it suitable for your travel bag or backpack rather than your pocket. It features two USB Type-C ports and one USB Type-A port, with the Type-C ports capable of delivering up to 140W of power. This allows for flexible charging configurations, such as 140W from a single port or a combination like 70W + 70W or 100W + 40W across both ports.

For gaming handhelds, the Steam Deck requires up to 38W, the Asus ROG Ally up to 65W, the Asus ROG Ally X up to 100W, and the Nintendo Switch up to 18W. The Anker 737 can charge all these devices at their maximum rates, enabling you to play and charge simultaneously.

With a 24,000mAh battery, which translates to a 74Whr capacity, and an 80% power efficiency rating, you get approximately 59Whr of usable charge. This means the power bank can fully charge a Steam Deck or Asus ROG Ally about 1.5 times, an Asus ROG Ally X about 0.75 times, and a Nintendo Switch around 3.7 times. This capacity underscores why a 20,000mAh power bank is considered the minimum for devices like the Steam Deck and Asus ROG Ally, especially the Ally X.

The Anker 737 is TSA-approved

The Transportation Security Administration (TSA) allows power banks with a capacity under 100Whr in carry-on luggage. The Anker 737, with its 74Whr capacity, comfortably meets this requirement. While its size might prompt additional checks, it has been cleared without issues at numerous airports, including Tokyo NRT.
