This USB battery dock adapter allows you to charge your GoPro HD battery from any USB wall charger (sold separately), from your computer, or in your car! It allows you to charge a single battery directly in the charger, or you can connect the charger to your GoPro HD camera via USB and charge the battery directly in the camera.
A blue light indicates that your battery is fully charged (or the charger is in standby with no battery); a purple light indicates that your battery is charging. Charging for 2 hours will get you a full charge. Includes 1 battery dock adapter and 1 USB to USB retractable cable.
Note: This is not a GoPro branded item & the battery is NOT included. The battery dock has a wall outlet prong on the rear which allows you to charge the battery via wall power, or USB power.
