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, 100W + 40W).

This power bank easily handles the charging needs of various gaming handhelds: The Steam Deck (up to 38W), Asus ROG Ally (up to 65W), Asus ROG Ally X (up to 100W), and Nintendo Switch (up to 18W). You can even charge and play simultaneously, even with the power-hungry ROG Ally X.

A 20,000mAh battery translates to approximately 74Whr capacity. Considering an 80% power efficiency (typical for power banks), you get around 59Whr of usable charge. This means you 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 highlights why a 20,000mAh capacity is crucial for power-demanding handhelds like the Steam Deck and ROG Ally (especially the Ally X).

TSA-Approved

The Anker 737's 74Whr capacity comfortably meets TSA carry-on requirements for power banks (under 100Whr; check-in is not permitted). While its size might prompt occasional checks, I've personally passed through numerous airport checkpoints with only one check (at Tokyo NRT) and cleared without issue.
