If you're on the hunt for an Anker power bank capable of powering high-demand gaming handhelds like the Steam Deck or ROG Ally X, Amazon currently has an incredible offer. You can grab the Anker PowerCore 737 24,000mAh 140W Power Bank for just $49.99. This deal is available through Woot, an Amazon-owned marketplace, and it's $20 less than the lowest price we've previously seen. As someone who has used this power bank for years across numerous flights and road trips, I can confidently say it's as good as new and highly recommend it.
Anker 737 24,000mAh 140W Power Bank for $49.99
Anker 737 PowerCore 24K 24,000mAh Power Bank with 140W USB Type-C Power Delivery
Originally priced at $149.99, this power bank is now available for $49.99 at Amazon, marking a 67% discount. The Anker 737 is an excellent choice for charging your Steam Deck. It's a substantial unit, measuring 4.6"x2.2"x2" and weighing 1.4lbs, making it better suited for a travel bag or backpack 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 allows for flexible power distribution, such as 140W from one port, or a combination like 70W + 70W or 100W + 40W across both.
For gaming handhelds, the power requirements are as follows: 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, it offers a 74Whr capacity. Assuming an 80% power efficiency, you get about 59Whr of usable charge. This means the power bank 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 about 3.7 times. This capacity underscores why a 20,000mAh power bank is the minimum recommended for power-hungry gaming handhelds like the Steam Deck and Asus ROG Ally, especially the Ally X.
The Anker 737 is TSA-approved
The TSA allows power banks under 100Whr in carry-on luggage (they're not permitted in checked bags). At 74Whr, the Anker 737 safely meets this requirement. While its size might prompt additional checks, it's generally cleared without issues. I've personally passed through numerous airport security checkpoints with this power bank and was only checked once at Tokyo NRT, where it was cleared without any problems.
