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, you can now save 67% and get it for $49.99 at Amazon. The Anker 737 stands out as one of the top choices for charging your Steam Deck. This power bank is on the larger side, measuring 4.6"x2.2"x2" and weighing 1.4lbs, making it more suitable for a travel bag or backpack 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 means it can deliver 140W through a single port or a combination of 140W across both ports, depending on the connected devices (e.g., 70W + 70W or 100W + 40W).

For gaming handhelds, the Steam Deck can charge at up to 38W, the Asus ROG Ally at up to 65W, the Asus ROG Ally X at up to 100W, and the Nintendo Switch at up to 18W. The Anker 737 can efficiently charge all these devices at their maximum rates, allowing you to play and charge simultaneously.

With a 24,000mAh battery, equivalent to a 74Whr capacity, and an 80% power efficiency rating (standard for power banks), you get approximately 59Whr of usable charge. This capacity allows the power bank to fully charge a Steam Deck or Asus ROG Ally (both 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 demonstrates why a 24,000mAh capacity is ideal for power-hungry gaming handhelds like the Steam Deck, Asus ROG Ally, and especially the ROG Ally X.

The Anker 737 is TSA-approved

The TSA permits power banks with a capacity under 100Whr in carry-on luggage (check-in is not allowed). At 74Whr, the Anker 737 falls safely within this limit. While its robust appearance might prompt a security check, it should clear without issues. I've personally passed through many airport checkpoints with this power bank, encountering a check only once at Tokyo NRT, and it was cleared without any problems.
