Anker 737 Power Bank: Now $49.99, Save 70%

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, you're in luck. Amazon is currently offering an incredible deal on the Anker PowerCore 737 24,000mAh 140W Power Bank, available for just $49.99. This deal is through Woot, which is owned by Amazon, and it undercuts the last lowest price we reported by about $20. Having used this power bank for several years across multiple flights and road trips, I can confidently say it's still in excellent condition and highly recommend it.

The Anker 737 is one of our top picks for charging the Steam Deck. This power bank is on the larger side, measuring 4.6"x2.2"x2" and weighing 1.4lbs, making it ideal for a travel bag or backpack rather 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 of power. This can be distributed as 140W from a single port or split between both ports, such as 70W + 70W or 100W + 40W, depending on your devices.

For gaming handhelds, 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. The Anker 737 can charge all these devices at their maximum rates, allowing for simultaneous play and charge.

With a 24,000mAh battery, equivalent to a 74Whr capacity, and an 80% power efficiency rating, this power bank provides about 59Whr of usable charge. This means it can fully charge a Steam Deck or Asus ROG Ally (both 40Whr) 1.5 times, an Asus ROG Ally X (80Whr) 0.75 times, and a Nintendo Switch (16Whr) about 3.7 times. This capacity makes it a solid choice 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, comfortably fits this requirement. Although its size might prompt a check, it's generally easy to get through airport security. I've personally passed through numerous checkpoints, including Tokyo NRT, with only one instance of being checked and cleared without issue.
