The PWR Headtorch is another piece of the PWR ecosystem. You can swap our different Lightheads and Power Banks, and use those pieces with other accessories like the Lanterns, and Speaker.
You can purchase this Headtorch as the straps alone if you already have elements of the PWR system, or you can purchase the Headtorch with a 1000lm Lighthead and small Power Bank, giving you a bundle savings.
For the Power Banks, simply remove the PWR Power Bank to connect another device's charge cable to the female USB port on the front of the PWR Bank and plug the other end of the USB cable into an available powered USB port. To charge the PWR Power Banks, use a micro USB input to charge through any USB port or USB wall plug charger.
