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, you're in luck. Amazon is currently offering a fantastic deal on the Anker PowerCore 737 24,000mAh 140W Power Bank, priced at just $49.99. This deal is through Woot, an Amazon-owned marketplace, and it undercuts the last lowest price we saw by about $20. As someone who has used this power bank extensively on flights and road trips, I can vouch for its durability and performance—it's still as good as new.

The Anker 737 is a top choice for charging your Steam Deck. This power bank is on the larger side, measuring 4.6"x2.2"x2" and weighing 1.4lbs, making it more suitable 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. This allows for flexible power distribution, such as 140W from a single port or a combination like 70W + 70W or 100W + 40W.

For gaming handhelds, 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. The Anker 737 can charge all these devices at their maximum rates, allowing you to play and charge simultaneously.

With a 24,000mAh battery, which translates to a 74Whr capacity, and an 80% power efficiency, you get about 59Whr of usable charge. This means you can fully charge a Steam Deck or Asus ROG Ally (both 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 highlights 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 up to 100Whr in carry-on luggage, and the Anker 737, with its 74Whr capacity, fits comfortably within this limit. Although its size might prompt a check at security, it should pass without issues. I've traveled through numerous airports and was only checked once at Tokyo NRT, where it was cleared without any problems.
