The Anker 737 is a substantial power bank, measuring 4.6"x2.2"x2" and weighing 1.4lbs, making it more suited 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 of power. This allows for flexible charging options, such as 140W from a single port or a combination like 70W + 70W or 100W + 40W from both ports, depending on the devices connected.
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 without any issues.
With a 20,000mAh 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 or Asus ROG Ally (both 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 is essential for power-hungry devices like the Steam Deck and Asus ROG Ally, especially the Ally X.
The TSA approves power banks under 100Whr for carry-on luggage, and the Anker 737, with its 74Whr capacity, fits comfortably within this limit. Although its size might prompt a check at airport security, it's generally cleared without issues. I've personally passed through numerous checkpoints, including Tokyo NRT, with only one inspection and no problems.
