If you're in the market for a power bank that can keep up with the high energy demands of gaming handhelds like the Steam Deck or ROG Ally X, you're in luck. Amazon is currently offering an unbeatable deal on the Anker PowerCore 737 24,000mAh 140W Power Bank, priced at just $49.99. This offer is through Woot, a marketplace vendor owned by Amazon, and it's $20 less than the lowest price we've previously seen. As someone who has used this power bank for 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 a top choice for charging devices like 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 your travel bag or backpack rather than a pocket. It features two USB Type-C ports and one USB Type-A port, with the USB Type-C ports capable of delivering up to 140W. This allows for configurations such as 140W from a single port, or combinations like 70W + 70W or 100W + 40W across both ports, depending on the devices connected.
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 and even supports simultaneous play and charging.
With a 20,000mAh battery, the Anker 737 offers a 74Whr capacity. Assuming an 80% power efficiency, you get around 59Whr of usable charge. This means you can fully charge a Steam Deck (40Whr) or Asus ROG Ally (40Whr) about 1.5 times, an Asus ROG Ally X (80Whr) about 0.75 times, and a Nintendo Switch (16Whr) around 3.7 times. This makes the 20,000mAh capacity a good baseline for power-hungry devices like the Steam Deck and Asus ROG Ally, particularly the Ally X.
The Anker 737 is TSA-approved
The TSA approves power banks under 100Whr for carry-on luggage, and the Anker 737, with its 74Whr capacity, fits comfortably within these guidelines. Although its size might prompt a check at airport security, it should clear without issues. I've personally passed through numerous checkpoints, including a single check at Tokyo NRT, and had no problems.
