If you're in the market for an Anker power bank that can keep up with the power demands of gaming handhelds like the Steam Deck or ROG Ally X, Amazon currently has an unbeatable deal. You can snag the Anker PowerCore 737 24,000mAh 140W Power Bank for just $49.99, courtesy of Woot, an Amazon-owned marketplace vendor. This price undercuts our previously reported lowest by approximately $20, and it's unlikely to get any cheaper. Having used this power bank for several years across numerous flights and road trips, I can confidently say it's still in excellent condition and highly recommend it.

The Anker 737 is a top choice for charging the Steam Deck, boasting a robust design that measures 4.6"x2.2"x2" and weighs 1.4lbs, making it more suited for a travel bag 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 140W from a single port or a combination like 70W + 70W or 100W + 40W across both ports.
When it comes to gaming handhelds, the Steam Deck can be charged 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 comfortably charge all these devices at their maximum rates, enabling simultaneous play and charging.
A 20,000mAh battery translates to a 74Whr capacity. With an 80% power efficiency rating, which is typical for power banks, you get about 59Whr of usable charge. This means the power bank can charge a Steam Deck or Asus ROG Ally from empty to full approximately 1.5 times, an Asus ROG Ally X about 0.75 times, and a Nintendo Switch around 3.7 times. This highlights why a 20,000mAh capacity is essential for powering more demanding gaming handhelds like the Steam Deck and Asus ROG Ally, especially the Ally X.
The Anker 737 is TSA-approved
The TSA stipulates that power banks for carry-on luggage must be under 100Whr, and the Anker 737 comfortably meets this requirement at 74Whr. While its size might draw some attention at security checkpoints, it should pass without issues. Personally, I've traveled through many airports and was only checked once at Tokyo NRT, where it was cleared without any problems.
