The Anker 737 is a top choice for charging Steam Decks, thanks to its robust capabilities. While it's larger and heavier at 4.6"x2.2"x2" and 1.4lbs, it's perfect for travel bags or backpacks rather than pockets. It features two USB Type-C ports and one USB Type-A port, with the Type-C ports supporting up to 140W of power delivery. This flexibility allows for a single port to deliver 140W or both to share the 140W total, adjusting based on connected devices (e.g., 70W + 70W or 100W + 40W).

For gaming handhelds, 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. The Anker 737 can efficiently charge all these devices at their maximum rates, enabling simultaneous play and charge.

A 20,000mAh battery translates to a 74Whr capacity. With an 80% power efficiency typical of power banks, you get about 59Whr of usable charge. This means the Anker 737 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) around 3.7 times. This demonstrates why a 20,000mAh capacity is essential for power-hungry gaming handhelds like the Steam Deck and Asus ROG Ally, especially the Ally X.

The Anker 737 is TSA-approved

The TSA mandates that carry-on power banks must be under 100Whr, and this Anker Prime comfortably meets that requirement at 74Whr. Although its size might prompt a check, it's generally cleared without issues. I've passed numerous airport security checks with it, encountering scrutiny only once at Tokyo NRT, where it was cleared without any problems.
