The Anker 737 is a top choice for charging the Steam Deck. It's a substantial unit, measuring 4.6"x2.2"x2" and weighing 1.4lbs, making it more suited for a travel bag or backpack rather than a 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 allows for flexible charging configurations such as 140W from a single port, or a combination like 70W + 70W or 100W + 40W when multiple devices are connected.

For gaming handhelds, the Steam Deck requires up to 38W for charging, 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 24,000mAh battery, equivalent to a 74Whr capacity, and an 80% power efficiency, this power bank offers about 59Whr of usable charge. This means it can fully charge a Steam Deck or Asus ROG Ally (40Whr each) about 1.5 times, an Asus ROG Ally X (80Whr) about 0.75 times, and a Nintendo Switch (16Whr) approximately 3.7 times. This capacity underscores why a 20,000mAh power bank is considered the minimum for power-hungry devices like the Steam Deck and Asus ROG Ally, especially the Ally X.

The Anker 737 is TSA-approved

The Anker 737 is well within the TSA's limit of 100Whr for carry-on luggage, with its 74Whr capacity. While its size might prompt a closer look at security checkpoints, it's fully compliant and should pass without issues. I've personally traveled through many airports with this power bank and was only checked once at Tokyo NRT, where it was cleared without any problems.
