If you're in the market for a power bank that can keep up with the demands of high-performance gaming handhelds like the Steam Deck or ROG Ally X, Amazon currently offers an exceptional deal. You can grab the Anker PowerCore 737 24,000mAh 140W Power Bank for just $49.99. This deal, available through Woot, which is owned by Amazon, undercuts our previously reported lowest price by about $20. Having personally used this power bank for several years, I can attest to its durability and reliability; it's been my companion on numerous flights and road trips and remains in excellent condition.
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, now available for $49.99 at Amazon, the Anker 737 is a top choice for charging devices like the Steam Deck. This robust power bank measures 4.6"x2.2"x2" and weighs 1.4lbs, making it more 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 Type-C ports supporting up to 140W of power delivery. This allows for flexible charging configurations such as 140W from a single port or combinations like 70W + 70W or 100W + 40W.
For gaming handhelds, the Steam Deck can charge 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 737 can charge all these devices at their maximum rates, enabling simultaneous play and charge.
With a 20,000mAh battery, equivalent to a 74Whr capacity, and an 80% power efficiency rating, you get about 59Whr of usable charge. This capacity allows you 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 approximately 3.7 times. This is why we recommend a minimum of 20,000mAh for power-hungry devices like the Steam Deck and Asus ROG Ally, particularly the Ally X.
The Anker 737 is TSA-approved
The TSA approves power banks under 100Whr for carry-on luggage, and the Anker 737 safely falls within this limit at 74Whr. While its size might prompt occasional checks, it should pass through airport security without issues. I've personally traveled with it through numerous airports, including a single check at Tokyo NRT, and it was cleared without any problems.
