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 has a fantastic deal. You can grab the Anker PowerCore 737 24,000mAh 140W Power Bank for just $49.99. This offer is available through Woot, which is owned by Amazon, and it's about $20 less than the lowest price we've previously seen. As someone who's used this power bank for several years across numerous flights and road trips, I can confidently say it's still in perfect condition and highly recommend it.
Anker 737 24,000mAh 140W Power Bank for $49.99
Anker 737 PowerCore 24K 24,000mAh Power Bank with 140W USB Type-C Power Delivery
Originally priced at $149.99, this power bank is now available at a 67% discount, making it an incredible deal at $49.99 on Amazon. The Anker 737 is a top choice for charging the Steam Deck due to its robust capacity and power output. It's a bit on the larger side, measuring 4.6"x2.2"x2" and weighing 1.4lbs, so it's better suited for your travel bag or backpack rather than your 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 versatile charging configurations, such as 140W from a single port or a combination like 70W + 70W or 100W + 40W.
For gaming handhelds, the Steam Deck can charge at up to 38W, the Asus ROG Ally at 65W, the Asus ROG Ally X at 100W, and the Nintendo Switch at 18W. The Anker 737 can handle charging all these devices at their maximum rates, allowing you to play and charge at the same time.
With a 24,000mAh battery, which translates to a 74Whr capacity, and considering an 80% power efficiency, you get about 59Whr of usable charge. This means the power bank 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 demonstrates why a 20,000mAh capacity is the minimum recommended for power-hungry devices like the Steam Deck and Asus ROG Ally, especially the Ally X.
The Anker 737 is TSA-approved
The TSA allows power banks up to 100Whr in carry-on luggage, and the Anker 737 comfortably fits within this limit at 74Whr. Although its hefty appearance might prompt a check at airport security, it's been cleared without issues in my experience, including at Tokyo NRT.
