If you're in the market for a power bank capable of meeting the high demands of gaming handhelds like the Steam Deck or ROG Ally X, Amazon currently has an unbeatable deal on the Anker PowerCore 737. Priced at just $49.99, this 24,000mAh, 140W power bank is available through Woot, which is owned by Amazon. This price undercuts our previously reported lowest price by about $20, making it an exceptional value. Having personally used this power bank for several years, I can attest to its durability and performance; it's been a reliable companion on numerous flights and road trips, remaining in excellent condition.
Anker 737 PowerCore 24K 24,000mAh Power Bank with 140W USB Type-C Power Delivery
Anker 737 24,000mAh 140W Power Bank for $49.99
Originally priced at $149.99, this power bank is now available at a 67% discount, making it a standout choice for Steam Deck users. The Anker 737 is a robust unit, measuring 4.6"x2.2"x2" and weighing 1.4lbs, 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 flexible power distribution, such as 70W + 70W or 100W + 40W, depending on the connected devices.
For gaming handhelds, the Anker 737 can charge the Steam Deck at its maximum rate of 38W, the Asus ROG Ally at 65W, the Asus ROG Ally X at 100W, and the Nintendo Switch at 18W. This means you can play and charge these devices simultaneously without any issues.
With a 20,000mAh battery, which equates to a 74Whr capacity, and an 80% power efficiency, you get approximately 59Whr of usable charge. This capacity allows the power bank to fully charge a Steam Deck or Asus ROG Ally 1.5 times, the Asus ROG Ally X 0.75 times, and the Nintendo Switch about 3.7 times. This demonstrates why a 20,000mAh capacity is recommended as a minimum for power-hungry devices like these.
The Anker 737 is TSA-approved
The Anker 737 is compliant with TSA regulations, with a capacity under the 100Whr limit for carry-on luggage. While its size might prompt additional checks, it should clear security without issues. I've personally traveled with this power bank through various airports, including a single check at Tokyo NRT, and it has always been approved.
