The Anker 737 is a substantial power bank, measuring 4.6"x2.2"x2" and weighing 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 of power. This allows for flexible charging options, such as 140W from a single port or a combination like 70W + 70W or 100W + 40W across both ports, depending on the devices connected.
For gaming handhelds, the Steam Deck requires up to 38W, the Asus ROG Ally up to 65W, the Asus ROG Ally X up to 100W, and the Nintendo Switch up to 18W. The Anker 737 can charge all these devices at their maximum rates, enabling 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 approximately 59Whr of usable charge. This means the power bank 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 essential for power-hungry devices like the Steam Deck and Asus ROG Ally, especially the Ally X.
The Anker 737 is TSA-approved
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, it's generally cleared without issues. I've personally passed through numerous airport checkpoints with this power bank, encountering a check only once at Tokyo NRT, and it was cleared without any problems.
