If you're in the market 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. The Anker PowerCore 737 24,000mAh 140W Power Bank is available for just $49.99. This offer is provided by Woot, an Amazon-owned marketplace vendor, and represents a $20 savings from the previously lowest price. Having used this exact model for years, I can confidently say it's a reliable choice; it has accompanied me on numerous flights and road trips and remains in excellent condition.
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 for $49.99, marking a 67% discount. The Anker 737 is particularly well-suited for charging the Steam Deck, thanks to its robust design. With dimensions of 4.6"x2.2"x2" and a weight of 1.4lbs, it's best suited for travel bags or backpacks rather than pockets. The power bank 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 versatile charging configurations, such as 140W from a single port or combinations like 70W + 70W or 100W + 40W across both ports.
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 charge all these devices at their maximum rates, enabling simultaneous play and charging.
With a 24,000mAh battery, equivalent to 74Whr, and an 80% power efficiency rating, this power bank provides about 59Whr of usable charge. This capacity allows it to fully charge a Steam Deck or Asus ROG Ally 1.5 times, an Asus ROG Ally X 0.75 times, and a Nintendo Switch 3.7 times. This demonstrates why a 20,000mAh capacity is considered 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, at 74Whr, comfortably meets this requirement. Although its size might prompt occasional checks, as I've experienced only once at Tokyo NRT, it has consistently cleared security without issues.
