Anker 737 PowerCore 24K 24,000mAh Power Bank with 140W USB Type-C Power Delivery

$149.99 save 67% - $49.99 at Amazon

The Anker 737 is a top choice for charging the Steam Deck. This robust power bank measures 4.6"x2.2"x2" and weighs 1.4lbs, making it ideal for a travel bag or backpack rather than a pocket. 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. This allows 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 requires 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 charge all these devices at their maximum rates, allowing for simultaneous play and charge.

With a 24,000mAh 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 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 underscores why a 20,000mAh power bank is essential for power-intensive devices like the Steam Deck and Asus ROG Ally, especially the Ally X.

The Anker 737 is TSA-approved

The Transportation Security Administration (TSA) approves power banks up to 100Whr for carry-on luggage, and the Anker 737 falls safely within this limit at 74Whr. While its substantial appearance might prompt additional checks, I've personally passed through numerous airport security checkpoints, including Tokyo NRT, without issues.
