Anker 737 Power Bank Now $49.99: Save 70% on 24,000mAh, 140W Model

If you're in the market for a robust power bank to keep your high-demand gaming handhelds like the Steam Deck or ROG Ally X charged, Amazon currently has an incredible deal on the Anker PowerCore 737. Priced at just $49.99, this 24,000mAh 140W power bank is a steal, especially when you consider it's being offered by Woot, an Amazon-owned marketplace, and is $20 less than its previously lowest price. Having used this power bank for several years across numerous flights and road trips, I can confidently say it's as reliable as it gets and still performs like new.

The Anker 737 stands out as one of our top recommendations for charging the Steam Deck. This substantial power bank measures 4.6"x2.2"x2" and weighs 1.4lbs, making it more suitable for a travel bag or backpack rather 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 charging options, such as 140W from a single port, or a combination like 70W + 70W or 100W + 40W when using both ports simultaneously.

For gaming handhelds, the Anker 737 can handle the maximum charging rates: 38W for the Steam Deck, 65W for the Asus ROG Ally, 100W for the Asus ROG Ally X, and 18W for the Nintendo Switch. This means you can play and charge your devices at the same time without any issues.

With a 20,000mAh battery, translating to a 74Whr capacity, and an 80% power efficiency rating, this power bank provides approximately 59Whr of usable charge. It can fully charge a Steam Deck or Asus ROG Ally 1.5 times, the Asus ROG Ally X 0.75 times, and the Nintendo Switch about 3.7 times. This capacity underscores why we advocate for a minimum of 20,000mAh when powering more demanding devices like the Steam Deck and Asus ROG Ally, particularly the Ally X.

The Anker 737 is TSA-approved

Traveling with this power bank is hassle-free as it's under the TSA's 100Whr limit for carry-on luggage. While its size might attract attention, it's perfectly compliant, and my experience through numerous airport checkpoints, including a single check at Tokyo NRT, confirms it's easily cleared.
