If you're in the market for a power bank that can keep up with the high demands of gaming handhelds like the Steam Deck or ROG Ally X, Amazon has a deal you won't want to miss. You can grab the Anker PowerCore 737 24,000mAh 140W Power Bank for just $49.99. This offer is through Woot, which is owned by Amazon, and it's a whopping $20 less than the last lowest price we reported. Having used this power bank for several years on various flights and road trips, I can confidently say it's a reliable choice and still performs as if it were brand new.

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 more suitable 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 means you can use one port at 140W or split the power between two ports (e.g., 70W + 70W or 100W + 40W), depending on your connected devices.
When it comes to gaming handhelds, the Steam Deck supports up to 38W of charging, 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 rate, allowing you to play and charge simultaneously.
With a 24,000mAh battery, equivalent to a 74Whr capacity, and an 80% power efficiency rating, you get about 59Whr of usable charge. This means the power bank can fully charge a Steam Deck or Asus ROG Ally (40Whr) 1.5 times, an Asus ROG Ally X (80Whr) 0.75 times, and a Nintendo Switch (16Whr) about 3.7 times. This capacity underscores why a 20,000mAh power bank is the minimum recommended for power-hungry gaming handhelds.
The Anker 737 is TSA-Approved
TSA regulations allow power banks under 100Whr in carry-on luggage (not permitted in checked bags). At 74Whr, the Anker 737 is well within these limits. Although its substantial size might attract some attention at airport security, it should clear without issues. I've personally passed through numerous checkpoints, including one at Tokyo NRT, and experienced no problems.
