The Anker 737 is a top pick for charging the Steam Deck and other gaming handhelds. It's a bit on the larger side at 4.6"x2.2"x2" and weighs 1.4lbs, making it more suitable for your travel bag 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 full speed with one port or split the power between two devices (e.g., 70W + 70W or 100W + 40W).

For gaming handhelds, the power delivery is more than sufficient: the Steam Deck charges at up to 38W, the Asus ROG Ally at 65W, the Asus ROG Ally X at 100W, and the Nintendo Switch at 18W. With the Anker PowerCore 737, you can charge all these devices at their maximum rates, allowing for simultaneous play and charging.

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 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 the minimum recommended 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, and the Anker PowerCore 737 fits comfortably within this limit at 74Whr. While its size might prompt a check, it has always cleared security without issues. I've personally passed through numerous airport checkpoints, including Tokyo NRT, with only one inspection and no problems.
