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 travel bags or backpacks rather than pockets. 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 combine for 140W, dynamically adjusting power distribution based on connected devices (e.g., 70W + 70W or 100W + 40W).

Regarding gaming handhelds, the Steam Deck supports up to 38W 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 easily charges all three gaming handhelds at their maximum rates, even allowing simultaneous charging and gameplay.

A 20,000mAh battery translates to approximately 74Whr capacity. Considering an 80% power efficiency rating (typical for power banks), you get roughly 59Whr of usable charge. This means the power bank 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 recommend at least a 20,000mAh capacity for power-hungry handhelds like the Steam Deck and ROG Ally (especially the Ally X).

TSA-Approved

The TSA mandates power banks under 100Whr for carry-on luggage (check-in is prohibited). At 74Whr, the Anker 737 comfortably meets this requirement. While its size might prompt occasional checks, I've personally passed through numerous airport security checkpoints with only one minor check (at Tokyo NRT), clearing without issue.
