The Anker 737 is a substantial power bank, with dimensions of 4.6"x2.2"x2" and a weight of 1.4lbs, making it more suited for your travel bag or backpack rather than a pocket. It features two USB Type-C ports and one USB Type-A port. The USB Type-C ports can deliver up to 140W of power, either through a single port or a combination across both (e.g., 70W + 70W or 100W + 40W), depending on the connected devices.
For gaming handhelds, the Anker 737 is more than capable. The Steam Deck can charge at up to 38W, the Asus ROG Ally at up to 65W, the Asus ROG Ally X at up to 100W, and the Nintendo Switch at up to 18W. This power bank can charge all these devices at their maximum rates, allowing you to play and charge simultaneously.
With a 20,000mAh battery, which translates to a 74Whr capacity, and an 80% power efficiency, you're looking at about 59Whr of usable charge. This means the Anker 737 can fully charge a Steam Deck or Asus ROG Ally about 1.5 times, the Asus ROG Ally X approximately 0.75 times, and the Nintendo Switch around 3.7 times. This capacity underscores why a 20,000mAh power bank is essential for power-hungry devices like the Steam Deck and Asus ROG Ally, especially the Ally X.
The Anker 737 is TSA-approved
The TSA allows power banks under 100Whr in carry-on luggage, and the Anker 737 comfortably fits this limit at 74Whr. Although its size might draw attention at security checkpoints, it should pass without issues. I've personally used it through numerous airports, including Tokyo NRT, and encountered no problems.
