    With a home made NEMA 14-50 to NEMA 5-15 adapter, I was able to test the unit at 120 VAC and it is a disaster:

    Tested with my Tesla Model 3, I could control the amps only to find the EVSE is unsafe to unsophisticated EV owners (aka., ex-wife.):
    • Initially tried to draw 31 A, the Tesla default
    • Stepped Tesla amps to generate the above chart
    • Typically 80% of the circuit breaker is the maxiumum safe load
      • 12 A - NEMA 5-15
      • 15 A - NEMA 5-20
      • Lower currents are OK and sometimes needed if other loads on the circuit
    I've already submitted a 'return' request and will be shipping it back. But I am quite disappointed by this unsafe performance.

    Again, I'm pretty sure that adapter is nothing but wires, and has no way to help any of that.

    It has to be implicit that if you're going to use a something-from-NEMA-5-15 adapter, you've already confirmed you can make your something work on 120 VAC and 12 amps or less.
