BMW I3 i3, i4 and Mini comes with a 30 amps (7kw) rated EVSE, also known as a mobile charging adapter. The EVSE comes with a NEMA 14-50 plug and a NEMA 5-15 plug.
This means when used with our 24 amps Splitvolt Splitter, SPS 01-031-01 and SPS 02C2-032, it will trip the breaker, typically in about 1hr.
