If you're in need of a reliable power bank for your power-hungry gaming handhelds like the Steam Deck or ROG Ally X, Amazon currently has an unbeatable deal on the Anker PowerCore 737 24,000mAh 140W Power Bank. Priced at just $49.99, this offer is available through Woot, a marketplace owned by Amazon. This price is about $20 less than the lowest we've seen before, and it's unlikely to get any cheaper. Having personally used this power bank for several years, I can attest to its durability and effectiveness; it has accompanied me on numerous flights and road trips and remains in excellent condition.

The Anker 737 is a top choice for charging gaming devices such as the Steam Deck. This robust power bank measures 4.6"x2.2"x2" and weighs 1.4lbs, making it ideal for travel bags or backpacks rather than pockets. 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 from both ports.

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 and even supports playing while charging.

With a 20,000mAh battery, equivalent to 74Whr, and an 80% power efficiency, you get approximately 59Whr of usable charge. This means you can charge a Steam Deck or Asus ROG Ally from empty to full 1.5 times, an Asus ROG Ally X 0.75 times, and a Nintendo Switch about 3.7 times. This capacity makes the Anker 737 a solid choice for power-intensive gaming handhelds.

The Anker 737 is TSA-approved

The TSA allows power banks under 100Whr in carry-on luggage, and the Anker 737 comfortably fits this limit at 74Whr. While its size may attract additional scrutiny at airport security, it's generally cleared without issues. I've personally passed through numerous checkpoints with this power bank and have only been checked once at Tokyo NRT, with no problems.
