Anker 737 PowerCore 24K 24,000mAh Power Bank with 140W USB Type-C Power Delivery
Anker 737 24,000mAh 140W Power Bank for $69.99
The Anker 737 is a robust power bank, measuring 4.6"x2.2"x2" and weighing 1.4lbs, making it more suited for a travel bag or backpack than a pocket. It features two USB Type-C ports and one USB Type-A port. The USB Type-C ports can deliver up to 140W of power, allowing for configurations like 140W from a single port, or 70W + 70W, or even 100W + 40W, depending on the devices connected.
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, enabling you to play and charge simultaneously without any issues.
A 24,000mAh battery translates to a 74Whr capacity. With an 80% power efficiency rating (standard for power banks), you get approximately 59Whr of usable charge. This means the Anker 737 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 power-hungry gaming handhelds like the Steam Deck, Asus ROG Ally, and especially the Ally X.
The Anker 737 is TSA-Approved
The TSA permits power banks with a capacity under 100Whr in carry-on luggage (checked luggage is prohibited). The Anker 737, with its 74Whr capacity, fits comfortably within these guidelines. While its size might attract some attention at security checkpoints, it's highly unlikely to cause any issues. I've personally passed through numerous airport security checks, including a thorough inspection at Tokyo NRT, and always cleared without hassle.
