This DC Adaptor is aimed at videographers who wish to power their 7.2V to 8.4V camcorder from professional V-Mount or PAGlok batteries. The DC Adaptor reduces the output of the battery to power the camera, producing longer run-time. V-Mount Belt Clip (Model 9522/60V) or PAGlok Belt Clip (Model 9522/60) is also required, and can be used to simultaneously power a 12V camera light, such as the Mini Paglight.
