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

$149.99 $69.99 at Woot! (Save 53%)

The Anker 737 is a substantial power bank (4.6"x2.2"x2", 1.4lbs), best suited for travel bags or backpacks. It features two USB Type-C ports and one USB Type-A port. The USB-C ports boast a maximum 140W power delivery – either 140W from a single port or a combined 140W across both (e.g., 70W + 70W or 100W + 40W).

This means it easily handles charging the Steam Deck (up to 38W), Asus ROG Ally (up to 65W), ROG Ally X (up to 100W), and Nintendo Switch (up to 18W) at their maximum rates. You can even play and charge simultaneously!

A 20,000mAh battery translates to roughly 74Whr. With an 80% power efficiency (typical for power banks), you get about 59Whr of usable charge. This allows for approximately 1.5 full charges of a Steam Deck or Asus ROG Ally (40Whr each), 0.75 full charges of an Asus ROG Ally X (80Whr), and about 3.7 full charges of a Nintendo Switch (16Whr). This highlights why we recommend at least a 20,000mAh capacity for power-hungry handhelds like the Steam Deck and ROG Ally (especially the Ally X).

TSA-Approved

The Anker 737 (74Whr) comfortably meets the TSA's carry-on limit of under 100Whr for power banks (check-in is not permitted). While its size might prompt occasional checks, I've personally passed through numerous airport security checkpoints with only one minor check (at Tokyo NRT).
