The Anker 737 is a substantial power bank, measuring 4.6" x 2.2" x 2" and weighing 1.4 lbs. It's best suited for a travel bag or backpack rather than a pocket. Featuring two USB Type-C ports and one USB Type-A port, the Type-C ports boast a maximum 140W power delivery. This means a single port can deliver 140W, or both ports can share the 140W depending on connected devices (e.g., 70W + 70W or 100W + 40W).

For gaming handhelds, this translates to: Steam Deck (up to 38W), Asus ROG Ally (up to 65W), Asus ROG Ally X (up to 100W), and Nintendo Switch (up to 18W). The Anker 737 easily charges all these devices at their maximum rate, even allowing simultaneous charging and gameplay.

A 20,000mAh battery equals approximately 74Whr capacity. With an 80% power efficiency (typical for power banks), you get about 59Whr of usable charge. This means you can fully charge a Steam Deck (40Whr) or Asus ROG Ally (40Whr) 1.5 times, an Asus ROG Ally X (80Whr) 0.75 times, and a Nintendo Switch (16Whr) about 3.7 times. This highlights why we consider a 20,000mAh capacity essential for power-hungry handhelds like the Steam Deck and ROG Ally (especially the Ally X).

TSA-Approved

The Anker 737's 74Whr capacity falls comfortably under the TSA's 100Whr carry-on limit (check-in is not permitted). While its size might attract attention, it shouldn't pose any significant issues at airport security. My personal experience includes numerous airport checkpoints, with only one check (at Tokyo NRT) resulting in a smooth clearance.
