Sharge Shargeek 300 Power Bank (300W, 24K, DC Ports, RGB Lights)

Overview

The Sharge Shargeek 300 (model X3) is a flagship 300W power bank launched on Kickstarter in February 2026. It pairs two 140W PD 3.1 USB-C ports with a unique adjustable DC barrel output (up to 140W) and a 20W USB-A port, letting it charge two laptops simultaneously plus a third device. Its 24,000mAh / 88.8Wh pack uses six Ampace 21700 Li-ion cells, keeps it airline carry-on safe, and refills in about an hour at 140W. The transparent aluminum body, customizable RGB lighting, and information-rich LCD display make it a standout for tech enthusiasts and content creators.
