I use this D-Tap dummy to power my smallHD 702 and bmpcc4k. In less than two months, he simply stopped transmitting energy out of thin air. I've tried several known good V-mount batteries and various known good devices that accept Canon batteries and the problem persists. Unfortunately you have to buy a better one.
