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 currently has an incredible deal on the Anker PowerCore 737 24,000mAh 140W Power Bank, available for just $49.99. This offer, brought to you by Woot, which is owned by Amazon, is $20 less than the last lowest price we've seen. Having personally used this power bank for several years across numerous 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 Steam Decks. This robust power bank measures 4.6"x2.2"x2" and weighs 1.4lbs, making it ideal for your travel bag or backpack rather than your pocket. It features two USB Type-C ports and one USB Type-A port. The USB Type-C ports can deliver up to 140W of power, allowing for configurations like 140W from a single port or a combination such as 70W + 70W or 100W + 40W.
For gaming handhelds, the Steam Deck supports up to 38W of charging, 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, enabling you to play and charge at the same time.
A 24,000mAh battery equates to a 74Whr capacity. With an 80% power efficiency rating, which is standard for power banks, you get approximately 59Whr of usable charge. This means the power bank can fully charge a Steam Deck (40Whr) or Asus ROG Ally (40Whr) 1.5 times, an Asus ROG Ally X (80Whr) 0.75 times, and a Nintendo Switch (16Whr) about 3.7 times. This capacity underscores why a 20,000mAh power bank should be the minimum for power-hungry devices 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 comfortably fits this limit at 74Whr. While its size might prompt a check at airport security, my experience through various checkpoints, including only one check at Tokyo NRT, confirms it passes without issues.
