The Anker 737 is a substantial power bank (4.6"x2.2"x2", 1.4lbs), best suited for a backpack or travel bag. It boasts two USB Type-C ports and one USB Type-A port. The USB-C ports offer a combined 140W power delivery (e.g., 70W + 70W, 100W + 40W).

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

A 20,000mAh battery translates to roughly 74Whr (80% efficiency). This provides approximately 59Whr of usable power, enough for:

Steam Deck/Asus ROG Ally: 1.5 full charges
Asus ROG Ally X: 0.75 full charges
Nintendo Switch: Approximately 3.7 full charges

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

With a 74Whr capacity, the Anker 737 comfortably meets TSA carry-on requirements for power banks (under 100Whr). While its size might attract attention, I've personally passed through numerous airport security checkpoints with minimal issues (only one check in Tokyo NRT).
