Silly question, but I don't have my home charger yet, and I don't have any 220v outlets in my house. I just want to get through the first week of driving around town without going to a supercharger. I'll plug it into a 120v line to keep it as charged as I can until an electrician actually calls back (why is this always a problem?) I finally found a plumber that responds, but never an electrician. At least call back and say sorry, I can't do it.
