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

This power bank easily handles charging various gaming handhelds at their maximum rates: 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 play and charge simultaneously.

With a 20,000mAh battery (approximately 74Whr) and an 80% power efficiency, you get roughly 59Whr of usable charge. This translates to approximately 1.5 full charges for a Steam Deck or Asus ROG Ally (40Whr), 0.75 charges for an Asus ROG Ally X (80Whr), and about 3.7 charges for a Nintendo Switch (16Whr). This highlights why a 20,000mAh capacity is ideal for power-hungry handhelds like the Steam Deck and ROG Ally (especially the Ally X).

TSA-Approved

The Anker 737's 74Whr capacity is well within the TSA's 100Whr carry-on limit. While its size might attract attention, I've personally passed through numerous airport checkpoints with minimal issues (only one check at Tokyo NRT).
