The Anker 737 is a robust power bank, measuring 4.6"x2.2"x2" and weighing 1.4lbs. It's designed to fit comfortably in your travel bag or backpack rather than your pocket. With two USB Type-C ports and one USB Type-A port, it's incredibly versatile. The USB Type-C ports can deliver up to 140W of power, allowing for flexible charging options such as 140W from a single port or a combination like 70W + 70W or 100W + 40W from both ports.

For gaming handhelds, the Steam Deck supports up to 38W, 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 can handle all these devices at their maximum charging rates, enabling you to play and charge simultaneously without any hiccups.

With a 20,000mAh battery translating to a 74Whr capacity, and considering an 80% power efficiency, you get about 59Whr of usable charge. This means the Anker 737 can fully charge a Steam Deck or Asus ROG Ally about 1.5 times, an Asus ROG Ally X approximately 0.75 times, and a Nintendo Switch around 3.7 times. This capacity underscores why a 20,000mAh power bank is essential for powering more demanding devices like the Steam Deck and Asus ROG Ally, especially the Ally X.

The Anker 737 is TSA-approved

The TSA approves power banks under 100Whr for carry-on luggage (check-in is strictly prohibited). At 74Whr, the Anker 737 safely falls within these limits. While its size might attract some attention at airport checkpoints, it's highly unlikely to cause any issues. I've personally passed through numerous security checks with this power bank and was only stopped once at Tokyo NRT, where it cleared without any problems.
