Extend your Nikon DSLR's battery life with an external battery or other DC power source using this EN-EL15 Dummy Battery from SmallRig. The adapter plugs into the 2.1mm DC barrel output of your battery plate or other power source, and the EN-EL15 dummy battery plugs into your Nikon camera's battery slot. Your camera can then benefit from higher-capacity external batteries or power adapters that can supply 7.4 VDC to your device.
