High current devices like aircons and I would expect electric car
battery chargers in countries like the USA are usually run on 220v

True that halves the current demand for the same power but does the
Tesla live off 110v (easyly available) or 220? Is 220 kit plugable
or hardwired? As you say it's only heavy load fixed kit that lives on
220 so it doesn't need to be plugable.

Even at 110v a 30m extension cable isn't that long, I'd almost need
that to get from a convient socket to where the cars park...
