This multi-battery adapter set allows you to connect and power a camera that uses an NP-FZ100 Z-series or NP-FW50 W-series battery. When the battery cover for the Z-series is removed, the power board fits cameras compatible with a W-series battery. A camera/USB selector switch enables you to toggle between the DC outputs, allowing you to choose whether to supply power to the camera body or to other electronic devices connected via USB. This battery adapter features three screw mounts on both the top and bottom (a total of 6 mounts), providing a flexible threaded attachment for a mounting plate and screws.
