>I don't know if there's a way to determine if they're behind the same breaker or not. Turn the breaker off and plug something in and see if it turns on

  Well yeah, but it'd be a bad idea to make a charger with two 120v plugs, because chances are people will plug them both into the same circuit.

    I'm not defending the idea of using two out-of-phase 110V circuits, but... this theoretical EVSE could detect its two inputs not being out-of-phase, blink its red "110V only" light, and only use one of the inputs to charge at 110V instead of 220V.

    I’ve seen carpet cleaners where their machine had two 120v cords that needed to be on different breakers
