The Anker 737 is a top choice for charging your Steam Deck. It's a bit on the larger side, measuring 4.6"x2.2"x2" and weighing 1.4lbs, so it's best suited for your travel bag or backpack rather than your pocket. It comes equipped with two USB Type-C ports and one USB Type-A port, with the USB Type-C ports capable of delivering up to 140W of power. This flexibility allows for configurations like 140W from a single port, or a combination such as 70W + 70W or 100W + 40W, depending on the devices you're charging.

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

With a 24,000mAh battery, which translates to a 74Whr capacity, and considering an 80% power efficiency rating, you get about 59Whr of usable charge. This means you 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 makes it clear why a 20,000mAh power bank should be considered 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 allows power banks under 100Whr in carry-on luggage, and the Anker 737, with its 74Whr capacity, fits perfectly within these guidelines. While its size might prompt a security check, it's generally cleared without issues. I've personally gone through numerous airport checkpoints and was only checked once at Tokyo NRT, where it passed without any problems.
