TORRAS FlexLine 3-in-1 Cube

The “FlexLine 3-in-1 Cube” features a maximum output of 45W for rapid charging and a 1-meter retractable Type-C cable, the longest in the series. By combining these three functions—rapid charger, mobile battery, and built-in cable—into a single unit, it aims to provide a convenient charging environment anytime, anywhere.

Furthermore, it includes a strap for easy carrying and drop prevention, a safe design utilizing next-generation GaN (gallium nitride) semiconductors, a large capacity of 10,000mAh, and the ability to charge both the device and the battery simultaneously from a single outlet. These features are designed to offer both high safety and superior convenience.

Product Features

  1. “Charger, Mobile Battery, Cable” – All-in-One Charging Solution
