I've personally used this power bank for over a year, taking it on numerous flights and road trips, and it's still going strong.

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 substantial power bank, with dimensions of 4.6"x2.2"x2" and a weight of 1.4lbs, making it ideal 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 of power. This means you can use a single port at 140W or split the power across both ports, such as 70W + 70W or 100W + 40W, depending on your connected devices.

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

With a 20,000mAh battery, equivalent to a 74Whr capacity, and an 80% power efficiency rating, you get approximately 59Whr of available charge. This means the power bank can fully charge a Steam Deck (40Whr) or Asus ROG Ally (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 capacity underscores why a 20,000mAh power bank should be the minimum for more power-intensive gaming handhelds like the Steam Deck, Asus ROG Ally, and especially the Ally X.

The Anker 737 is TSA-approved

The TSA approves power banks with a capacity under 100Whr for carry-on luggage (check-in is prohibited). The Anker 737, at 74Whr, comfortably meets this requirement. While its robust appearance might prompt a check, it should pass without issues. I've personally gone through numerous airport checkpoints with this power bank and was only checked once at Tokyo NRT, passing without any problems.
