How much do you love your parents? lolis the 12 amp worth it that much even on a 220?
or what about if im at my folks 40 year old house with shady wiring and need a quick top off. will 12amps burn their house down?!?
I'm with TSquare here. Why risk it? I live in a 40 year old house and I never tried 12A. I had a dedicated 220V 50A line installed for the Volt.
