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, Woot! is currently offering an unbeatable deal. You can grab the Anker PowerCore 737 24,000mAh 140W Power Bank for just $69.99. Amazon Prime members enjoy free shipping, while others pay a nominal $6 fee. This is the lowest price we've seen for what we consider one of the top chargers for the Steam Deck and Asus ROG Ally X. Having used this power bank for over a year, I can attest to its durability and reliability, having taken it on numerous flights and road trips without any issues.
Anker 737 24,000mAh 140W Power Bank for $69.99
Anker 737 PowerCore 24K 24,000mAh Power Bank with 140W USB Type-C Power Delivery
Originally priced at $149.99, you can now save 53% and get it for $69.99 at Woot! The Anker 737 is a robust power bank, measuring 4.6"x2.2"x2" and weighing 1.4lbs, making it more suitable for a travel bag or backpack 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 charging options, such as 140W from a single port or a combination like 70W + 70W or 100W + 40W across both ports.
For gaming handhelds, the Anker 737 excels in meeting their power needs. The Steam Deck requires up to 38W, the Asus ROG Ally up to 65W, the Asus ROG Ally X up to 100W, and the Nintendo Switch up to 18W. With the Anker Prime, you can charge all these devices at their maximum rate, and even play while charging.
With a 20,000mAh battery equating to a 74Whr capacity and 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, the Asus ROG Ally X 0.75 times, and the Nintendo Switch 3.7 times. This capacity underscores 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, at 74Whr, fits comfortably within these limits. While its size might attract additional scrutiny, it's generally easy to get through airport security. I've personally used it at multiple checkpoints, including Tokyo NRT, without any issues.
