If you're on the hunt for an Anker power bank capable of powering demanding 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, facilitated through Woot, which is owned by Amazon, is $20 less than the lowest price we've previously reported, and it's unlikely to get any cheaper. Having used this power bank for several years across multiple flights and road trips, I can confidently say it remains in excellent condition and is highly recommended.

The Anker 737 is a top choice for charging the Steam Deck, featuring a robust design measuring 4.6"x2.2"x2" and weighing 1.4lbs. It's designed for travel bags or backpacks rather than pockets. It includes 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 versatile charging configurations, such as 140W from a single port or combinations like 70W + 70W or 100W + 40W across both ports.

For gaming handhelds, the power bank can charge a Steam Deck at up to 38W, an Asus ROG Ally at up to 65W, an Asus ROG Ally X at up to 100W, and a Nintendo Switch at up to 18W. This means it can fully 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, you get about 59Whr of usable charge. This capacity allows the power bank 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 highlights why a 20,000mAh capacity is essential for power-intensive gaming handhelds like the Steam Deck and Asus ROG Ally, especially the Ally X.

The Anker 737 is TSA-approved

The TSA approves power banks under 100Whr for carry-on luggage, and the Anker 737 fits comfortably within this limit at 74Whr. Its substantial appearance might prompt a security check, but it should clear without issues. Personally, I've passed through numerous airport security checkpoints with only one inspection at Tokyo NRT, and it was cleared without any problems.
