Description

The Portkeys BD4 is a unique rotatable adapter that combines two NPF batteries into a double-sided V-mount power source with an integrated dummy battery output. Its 360° rotatable body and dual-sided V-lock plate (front/back) offer unmatched mounting flexibility. The key addition is a dedicated dummy battery cable (e.g., for Sony, Canon, Panasonic cameras), enabling direct camera power alongside standard V-mount/D-Tap outputs. Ideal for powering mirrorless/DSLR cameras and accessories simultaneously using cost-effective NPF batteries.


Double-Sided V-Mount (360° Rotatable)
Mount on either side for ultimate flexibility in tight spaces. 

Dual NPF Battery Input
Combines power of two NPF batteries (e.g., NPF-970) for extended runtime.

Integrated Dummy Battery Output
Directly powers compatible cameras (e.g., Sony FX3, A7S III, Canon R5C) via included cable.

V-Mount + D-Tap Outputs
Simultaneously powers accessories (monitors, lights, transmitters). 

Unified Power Solution
Eliminates separate camera batteries & accessory power sources.

Compact & Cost-Efficient
Leverages affordable NPF batteries instead of large V-mount packs.
