I wonder if hauling around a small step-up transformer would make it possible to charge at level 2 rate from 30-amp service (120V). The upgraded rev2 EVSE draws 16 amps at 240V, so using a transformer would double it to 32 amps at 120V. Unfortunately, that's a bit more than 30 amps so it might risk popping the breaker. But it would be enticing to be able to use the 30 amp TT-30 receptacles so common at RV parks.
