Uh the 3.7KW charger would in fact take an electrical modification. It would at 120 volts draw about 30 amps. Uh Oh household wiring is for a typical outlet 20 amps at 120 volts at maxed out 2400 watts or 2.4KW. Anyways based on what these chargers require in electrical power demand and modifications? No thanks I’ll stick with gasoline.
The only 3.7 kw charger I see is 240v.
