If you're in the market for a power bank that can keep up with the energy demands of high-performance 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. This offer is through Woot, which is owned by Amazon, and it undercuts our previously reported lowest price by $20. Having personally used this power bank for several years across multiple flights and road trips, I can attest to its durability and reliability.

The Anker 737 stands out as one of the best chargers for the Steam Deck due to its robust capabilities. This power bank is on the larger side, measuring 4.6"x2.2"x2" and weighing 1.4lbs, making it more suited 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. 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 power bank's specs are impressive. It supports up to 38W for the Steam Deck, 65W for the Asus ROG Ally, 100W for the Asus ROG Ally X, and 18W for the Nintendo Switch. This means the Anker 737 can charge all these devices at their maximum rate, allowing for simultaneous play and charge.
With a 24,000mAh battery, which translates to a 74Whr capacity, and an 80% power efficiency rating, you get approximately 59Whr of usable charge. This capacity allows the power bank to fully charge a Steam Deck or Asus ROG Ally about 1.5 times, the Asus ROG Ally X about 0.75 times, and the Nintendo Switch around 3.7 times. This demonstrates why a 20,000mAh capacity is considered the minimum for powering demanding gaming handhelds.
The Anker 737 is TSA-approved
The Anker 737 is well within TSA guidelines, with its 74Whr capacity falling safely under the 100Whr limit for carry-on luggage. Although its size might attract attention, it's been cleared at numerous airport checkpoints, including once at Tokyo NRT, without any issues.
