This D-Tap Cable to Sony NP-BX1-Type Dummy Battery from IndiPRO Tools allows a power source with a D-Tap output to connect to devices that operate using a Sony NP-BX1-type battery. The 24" cable features a dummy battery that fits inside the camera body to power it for extended periods of time, like when shooting video content. The cable is made from 18-gauge stranded copper wire, and the built-in emulator chip delivers battery status data to the camera.
