Power your BMPCC4K/6K with a Porta-Pak battery or similar power distribution devices using this Porta-Pak 2.5mm Connector to Coiled 2-Pin Connector from IndiPRO Tools. The cable features a 2.5mm male connector on one end and dedicated 2-pin power connector for the BMPCC4K/6K camera on the other. It measures 18″ when fully contracted and extends to up to 40″. This coiled factor of the cable provides the flexibility to run the cable from one end of your rig to the other, while also letting you keep a neat connection if your power source is close to the camera. Please note that this cable is not power regulated and will pass whatever voltage through it that you connect the cable to.
