The Anker 737 is a substantial power bank (4.6"x2.2"x2", 1.4lbs), best suited for a backpack or travel bag. It features two USB Type-C ports (each supporting up to 140W, or a combined 140W) and one USB Type-A port.

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) can all be charged at their maximum rate simultaneously.

With a 20,000mAh battery (approximately 74Whr), and accounting for an 80% power efficiency, you get roughly 59Whr of usable charge. This translates to approximately 1.5 full charges for a Steam Deck or ROG Ally, 0.75 charges for a ROG Ally X, and about 3.7 charges for a Nintendo Switch. This highlights why a 20,000mAh capacity is ideal for power-hungry devices 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). While its size might prompt occasional checks, I've personally traveled extensively with it, experiencing only one check (at Tokyo NRT), which was cleared without issue.
