The Anker 737 is highly regarded as one of the top chargers for the Steam Deck. Its dimensions are 4.6"x2.2"x2" and it weighs 1.4lbs, making it suitable for travel bags or backpacks rather than pockets. It features two USB Type-C ports and one USB Type-A port, with the USB Type-C ports capable of delivering up to 140W of power. This allows for configurations such as 140W from a single port, or 70W + 70W, or 100W + 40W when using both ports.
For gaming handhelds, the Steam Deck can draw 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 efficiently charge all these devices at their maximum rates, enabling simultaneous play and charging.
With a 20,000mAh battery, equivalent to a 74Whr capacity, and an 80% power efficiency rating, you get approximately 59Whr of usable charge. This means the power bank can fully charge a Steam Deck (40Whr) or Asus ROG Ally (40Whr) about 1.5 times, an Asus ROG Ally X (80Whr) about 0.75 times, and a Nintendo Switch (16Whr) around 3.7 times. This capacity makes it clear 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 with a capacity under 100Whr in carry-on luggage (check-in is prohibited). At 74Whr, the Anker 737 is well within these limits. While its robust appearance might trigger an occasional check, as I experienced at Tokyo NRT, it has consistently passed security without issues.
