Anker 737 24,000mAh 140W Power Bank for $69.99

Anker 737 PowerCore 24K 24,000mAh Power Bank with 140W USB Type-C Power Delivery

Originally priced at $149.99, you can now save 53% and get it for $69.99 at Woot! The Anker 737 is a robust power bank, measuring 4.6"x2.2"x2" and weighing 1.4lbs, making it more suitable for a travel bag or backpack rather than a pocket. It features two USB Type-C ports and one USB Type-A port, with the Type-C ports supporting up to 140W of power delivery. This means a single port can deliver 140W, or both can share a combined 140W, depending on the devices connected (e.g., 70W + 70W or 100W + 40W).

For gaming handhelds, the Steam Deck charges 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 PowerCore 737 can charge all these devices at their maximum rates, allowing you to play and charge at the same time.

A 24,000mAh battery equates to a 74Whr capacity. With an 80% power efficiency rating, you get about 59Whr of usable charge. This means the power bank can charge a Steam Deck (40Whr) or Asus ROG Ally (40Whr) from empty to full approximately 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 20,000mAh capacity is considered the minimum for power-intensive gaming handhelds like the Steam Deck, Asus ROG Ally, and especially the Ally X.

The Anker 737 is TSA-Approved

The TSA allows power banks under 100Whr in carry-on luggage (check-in is prohibited). With its 74Whr capacity, the Anker 737 comfortably meets these requirements. Although its hefty appearance might prompt a check, you should have no trouble getting it through airport security. I've personally passed through numerous checkpoints, including Tokyo NRT, and was only checked once, clearing without issues.
