The D10 requires 12 volts, and you have to have the DCP-80 to make it work. The DCP-80 goes into the battery slot, and has a 12-volt input that can be used with a car lighter adaptor or any 12volt battery system. Eco-charge used to have a setup for it years ago, don't know if they still do. The DCP-80 is a very hard part to find, took me a LONG time to get one.
