Thinkware iVolt Mini External Battery (IVOLTMN) suits all Thinkware dash cam series. This battery pack charges while the vehicle is driving and powers your dash cam during parking mode instead of drawing current from the vehicles battery. It will only work with hardwired dash cams, and it simply hardwires to the vehicles battery or fusebox and requires a Thinkware Hard Wire Cable Kit (HWC) to connect to the dash cam.
