If you're in the market for a power bank that can keep up with the high energy demands of gaming handhelds like the Steam Deck or ROG Ally X, Amazon currently has an unbeatable deal on the Anker PowerCore 737 24,000mAh 140W Power Bank, priced at just $49.99. This offer is available through Woot, which is owned by Amazon, and it's $20 less than the previous lowest price we've seen. Having used this power bank for several years, I can confidently say it's a reliable choice, having accompanied me on numerous flights and road trips without any issues.

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

Original Price: $149.99
Discount: 67%
Current Price: $49.99 at Amazon

The Anker 737 is a top choice for charging devices like the Steam Deck. Its dimensions are 4.6"x2.2"x2", and it weighs 1.4lbs, making it suitable for your travel bag or backpack rather than a 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 70W + 70W or 100W + 40W, depending on the connected devices.

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, allowing you to play and charge simultaneously.

With a 20,000mAh battery, equivalent to a 74Whr capacity, and an 80% power efficiency rating, this power bank provides about 59Whr of usable charge. This is enough 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 capacity is why we recommend a minimum of 20,000mAh for power-hungry gaming handhelds.

The Anker 737 is TSA-approved

The TSA allows power banks under 100Whr in carry-on luggage, and the Anker 737 fits safely within this limit at 74Whr. Though its size may prompt occasional checks, it should clear security without issues. I've personally used it through many airport checkpoints, including a single check at Tokyo NRT, and it was cleared without any problems.
