If you're in the market for a reliable 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 an incredible deal on the Anker PowerCore 737 24,000mAh 140W Power Bank, available for just $49.99. This deal is brought to you by Woot, a marketplace vendor owned by Amazon, and it's a significant $20 drop from the last lowest price we tracked. Having used this power bank myself for several years, I can confidently say it's a stellar choice. It has accompanied me on numerous flights and road trips and remains in excellent condition.

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

Current Price: $49.99 at Amazon

The Anker 737 is a top pick for charging devices like the Steam Deck. This power bank, while on the larger side at 4.6"x2.2"x2" and weighing 1.4lbs, is perfect for your travel bag or backpack. 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 flexibility allows you to charge multiple devices simultaneously at optimal rates, such as 70W + 70W or 100W + 40W.

For gaming handhelds, the power delivery is more than sufficient: the Steam Deck charges at up to 38W, the Asus ROG Ally at 65W, the Asus ROG Ally X at 100W, and the Nintendo Switch at 18W. The Anker PowerCore 737 can handle all these devices at their maximum charging rates, enabling you to play and charge at the same time.

With a 24,000mAh capacity, which equates to approximately 74Whr, and an 80% power efficiency rating, you get about 59Whr of usable charge. This capacity allows the power bank to fully charge a Steam Deck or Asus ROG Ally 1.5 times, an Asus ROG Ally X 0.75 times, and a Nintendo Switch about 3.7 times. This demonstrates why a 20,000mAh capacity is essential for powering demanding gaming handhelds.

The Anker 737 is TSA-approved

The Transportation Security Administration (TSA) approves power banks with a capacity under 100Whr for carry-on luggage (check-in is prohibited). The Anker PowerCore 737, at 74Whr, fits comfortably within these limits. Although its robust appearance might prompt a check at airport security, it should clear without issues. I've personally traveled through many airports with this power bank and was only inspected once, at Tokyo NRT, and passed without any problems.
