The IndiPRO Tools Mini-Tap with 4-pin XLR Connector Cable allows you to simultaneously power up to three devices from a V-Mount or Gold Mount battery that has a D-Tap port.
On one end, the cable features a T-shaped component with a male D-Tap connector on the bottom, a female D-Tap port on the side, and a USB port on the other side. The male D-Tap is for plugging into the V-Mount/Gold Mount battery, sold separately. On the other end of the cable is a 4-pin Neutrik XLR female connector for plugging into cameras and other devices.
The USB port outputs 5V of power at up to 2A, allowing you to connect most mobile and select audio devices on set.
