Portkeys NPF to V-mount dummy battery adapter for V-mount video transmission

The Portkeys BD4 is a versatile NP-F to V-Mount dummy battery adapter designed for video transmission systems, featuring multiple power inputs and a direct pass-through voltage system for seamless integration into your rig.

The Portkeys BD4 NP-F to V-Mount Dummy Battery Adapter is engineered for creators who demand flexibility and reliability in powering video transmission systems and other camera gear. Crafted from aluminum alloy and ABS engineering plastics, the BD4 is durable yet compact, measuring 93.1 x 71 x 46.7 mm and weighing 204g.

With dual input options, including a BP port (7–16.8V) and a USB-C PD 3.1 port supporting up to 15V, the BD4 provides unmatched versatility. It delivers direct voltage output for both NP-F and V-Mount ports—meaning the output voltage mirrors the input voltage (7–16.8V), allowing consistent, regulated power for sensitive devices.

Perfect for powering video transmission modules and other rig-mounted equipment, the BD4 ensures clean and efficient power distribution in the field or studio.
