SmallHD's FOCUS monitors have a power output for smaller cameras, and with this FOCUS to Nikon EN-EL14 Power Adapter, you can power your Nikon DSLR camera right off the monitor. Insert the dummy battery end into your camera and connect it up to the FOCUS monitor's output for power. Powering the camera using the montior's battery will result in a simplified power setup and longer shooting times between charges, compared to the standard internal batteries.
Note: Check your camera's manual to ensure compatibility with the dummy battery type.
