You will need to have a 220 outlet installed to use this. If you look at the wiring you will see that this has never been used.  I have not tested it because I do not have a 220 outlet at my house. These are rare and hard to find. I'm not sure but I believe these are also compatible with other EVs.  As long as they have the standard J1772 Plug and can take 240v.  Contact your dealer or do your research before using it with another type of vehicle.
