The Anker 737 is renowned as one of the best chargers for the Steam Deck. Its dimensions are 4.6"x2.2"x2" and it weighs 1.4lbs, making it more suitable for a travel bag or backpack rather than a 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. This allows for flexible power distribution, such as 140W from a single port, or combinations like 70W + 70W or 100W + 40W across both ports.

For gaming handhelds, the Steam Deck can charge at up to 38W, the Asus ROG Ally at 65W, the Asus ROG Ally X at 100W, and the Nintendo Switch at 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, equivalent to a 74Whr capacity, and an 80% power efficiency rating, you get around 59Whr of usable charge. This means you can fully charge a Steam Deck (40Whr) or Asus ROG Ally (40Whr) 1.5 times, an Asus ROG Ally X (80Whr) 0.75 times, and a Nintendo Switch (16Whr) about 3.7 times. This capacity underscores why a 20,000mAh power bank should be the minimum for devices like the Steam Deck and Asus ROG Ally, especially the Ally X.

The Anker 737 is TSA-approved

TSA regulations allow power banks under 100Whr in carry-on luggage, and the Anker 737 fits comfortably within this limit at 74Whr. While its robust appearance might attract attention at security checkpoints, you shouldn't face any issues. I've passed through numerous airport checkpoints with this power bank and was only inspected once at Tokyo NRT, where it was cleared without issue.
