The MH-67P Battery Charger from Nikon is an external battery charger for use with the P600 digital point and shoot camera. It is designed to charge the P600's EN-EL23 lithium ion battery when it is outside the camera. This charger can prove to be a very useful accessory for you when going on long trips, as there will be very few places where you can recharge your electronic devices. It can be used to charge the main, as well as spare camera batteries. The small form factor of this charger enables you to easily carry it in your camera bag or any other travel bag.
