This BLUESHAPE P-Tap Power Adapter allows you to connect the BLUESHAPE BUBBLEPACK battery to the Nikon D4 camera. It features a proprietary, blue P-Tap connector specific to the BLUESHAPE BUBBLEPACK.
Note: The blue P-Tap connector is a proprietary BLUESHAPE connector that can be switched between 8.4V and 11.1V via the BLUESHAPE BUBBLEPACK. The voltage level should be set to match the camera's voltage or an overload could potentially be delivered to the camera. If the blue P-Tap connector is modified for use with a battery other than the BUBBLEPACK, it will deliver 14.8V and can cause an issue.
