The NPA-MQZ1K multi battery adapter kit isn't compatible with these accessories:
- GP-X1EM Grip Extension
You can't use this grip with the multi battery adapter kit because it will interfere with the cord of the plug-in plate when it's attached to the camera.
- VG-C3EM, VGC-2EM, and VG-C1EM Vertical Grips
The plug-in plate isn't compatible with the battery trays.
- Camera body cases
Most camera body cases block the battery cover where it attaches to the plug-in plate.
