You'll need the adapter.
When I'm at home, I leave my Mirada plugged into a 15 amp (20 amp) circuit, mainly to keep the batteries charged.
When plugged into the low current, just remember no high current items can be operated simultaneously. i.e. I can make coffee, but cant run the microwave or the AC at the same time.

It won't do MACH 2, but I can get a sandwich and take a pee.
