It's not clear to me from the description, I understand that in the US the wall sockets don't put out a lot of juice, (120 volts at 15 amps = 1.8kW) but is "Level 2" like my household wall sockets (240 volts at 13 amps = 3.1kW) or is it more (e.g. some of my friends installed 240 volts at 30 amps = 7.2kW to cut their charging time in half) ?

[ Also, presumably Americans do have electric ovens right? So your ovens can't be 120 volts at 15 amps, that'd be like a kid's toy, there must be beefier power inside a typical American house already, albeit maybe not near the car? ]
