Nothing is more unfavourable than a flat accumulator in the camera away. Even if a change accumulator is to its hand, one must stop nevertheless and pass minutes until the camera is ready for use again. Because of this many a terrific photo, a call or another important moment was already missed.
Raul has solved this problem now and developed a permanent power supply. For the GoPro cameras, but could be operated also much other equipment with the supply set. The assembly me rather simple. The plugs plug in and the cable with ribbons or similar fix at the two ends.
