The Anker 737 is a top choice for charging devices like the Steam Deck. This power bank, which measures 4.6"x2.2"x2" and weighs 1.4lbs, is best suited for travel bags or backpacks rather than pockets. 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 means you can use a single port at 140W or split the power between both ports (e.g., 70W + 70W or 100W + 40W), depending on your devices.

When it comes to gaming handhelds, the Steam Deck can charge 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 handle charging all these devices at their maximum rates, allowing you to play and charge at the same time.

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 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 highlights why a 20,000mAh capacity is considered the minimum for power-hungry gaming handhelds like the Steam Deck and Asus ROG Ally, especially the Ally X.

The Anker 737 is TSA-approved

The TSA allows power banks under 100Whr in carry-on luggage (check-in is prohibited). The Anker 737, with its 74Whr capacity, comfortably meets this requirement. Although its size might attract attention at airport checkpoints, it's highly unlikely to cause any issues. I've personally passed through numerous checkpoints with this power bank and was only checked once, at Tokyo NRT, and cleared without any problems.
