Heads up readers, during the NAB2016 Show next week keep an eye out on these particular IndiPRO Tools power cables for an additional discount. These cables offer a custom Mini-Tap to Dummy battery that can keep your Canon or Sony cameras powered up from a V-mount or Gold Mount battery. The cable is regulated inline to ensure your camera is operating at the correct voltage (as v-mounts are typically 14V+ out).
The difference between these cables as opposed to a standard D-Tap is the custom Mini-Tap which splits into two additional power option. (Other cables pretty much hog the entire D-Tap port). Once connected to your v-mount battery, you will still have an option for an unregulated D-Tap out to power up an additional accessory + a USB 5V out. That's three possible accessories you can power from a single battery without an expensive distribution system.
