The Anker 737 is a robust power bank, measuring 4.6"x2.2"x2" and weighing 1.4 lbs. It’s designed for travel rather than pocket-sized convenience. Equipped with two USB Type-C ports and one USB Type-A port, it supports up to 140W of power delivery via the Type-C ports. This means each port can output up to 140W individually, or the total output can be split between connected devices—for instance, 70W + 70W or 100W + 40W.

When it comes to gaming handhelds, the Steam Deck handles 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 737 effortlessly charges all these devices at their maximum rates, allowing you to play while charging.

A 20,000mAh battery equals a 74Whr capacity. With an 80% efficiency rating, you get approximately 59Whr of usable energy. This translates to about 1.5 full charges for a Steam Deck (40Whr) or Asus ROG Ally (40Whr), 0.75 charges for an Asus ROG Ally X (80Whr), and roughly 3.7 charges for a Nintendo Switch (16Whr). Clearly, this makes the 24,000mAh capacity ideal for power-hungry devices like the Steam Deck and ROG Ally.

TSA-Approved Design

According to TSA guidelines, power banks under 100Whr are permitted for carry-on luggage (checked baggage is never allowed). The Anker 737 measures at 74Whr, making it fully compliant. While its size may attract attention during security checks, it has consistently passed through airports without issues. In my experience, I’ve only been questioned once at Tokyo NRT but was ultimately cleared without hassle.
