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 fantastic deal that you won't want to miss. Currently, you can grab the Anker PowerCore 737 24,000mAh 140W Power Bank for just $49.99, thanks to Woot, an Amazon-owned marketplace vendor. This price is $20 less than the last time we highlighted it, and it's unlikely to drop any further. Having used this power bank for several years across numerous flights and road trips, I can confidently say it's as good as new and highly recommend it.

The Anker 737 stands out as one of our top picks for charging the Steam Deck. This robust power bank measures 4.6"x2.2"x2" and weighs 1.4lbs, making it more suited for your travel bag or backpack than your pocket. It features two USB Type-C ports and one USB Type-A port, with the Type-C ports capable of delivering up to 140W of power. This allows for versatile charging configurations, such as 140W from a single port or a combination like 70W + 70W or 100W + 40W.

For gaming handhelds, the Steam Deck charges 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. The Anker 737 can charge all these devices at their maximum rates, enabling you to play and charge at the same time.

With a 24,000mAh battery, equivalent to a 74Whr capacity, and an 80% power efficiency rating, this power bank offers about 59Whr of usable charge. This means it can fully charge a Steam Deck or Asus ROG Ally 1.5 times, an Asus ROG Ally X 0.75 times, and a Nintendo Switch 3.7 times. This capacity underscores why a 20,000mAh minimum is recommended for power-hungry gaming handhelds like the Steam Deck, Asus ROG Ally, and especially the Ally X.

The Anker 737 is TSA-approved

The TSA approves power banks with capacities under 100Whr for carry-on luggage, and the Anker 737 comfortably fits this requirement at 74Whr. While its substantial appearance might prompt a check at security, it should pass without issues. I've personally carried it through numerous airport checkpoints, with only one check at Tokyo NRT, and it was cleared without any problems.
