The Anker 737 is a top choice for charging devices like the Steam Deck. This robust power bank measures 4.6"x2.2"x2" and weighs 1.4lbs, making it more suitable for your travel bag or backpack 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. This means you can charge at 140W from a single port or split the power between both ports, such as 70W + 70W or 100W + 40W, depending on your connected devices.

For 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 charge all these devices at their maximum rates, allowing you to play and charge simultaneously.

With a 24,000mAh battery, equivalent to a 74Whr capacity, and an 80% power efficiency rating, you get about 59Whr of usable charge. This means the power bank can fully charge a Steam Deck (40Whr) or Asus ROG Ally (40Whr) about 1.5 times, an Asus ROG Ally X (80Whr) about 0.75 times, and a Nintendo Switch (16Whr) around 3.7 times. This capacity underscores why a 20,000mAh power bank is the minimum recommended for power-hungry devices 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, and the Anker 737, at 74Whr, fits comfortably within this limit. While its size might prompt a check at airport security, it's been cleared without issues in my experience, including at Tokyo NRT.
