    I think #1 is suggesting to move the neutral over to another hot phase and change the outlet to a 240v nema 6/three prong (I think) with two hots and a ground instead of the 4 prong.

    The 240v at the same amps gives you higher watts so faster charging without an expensive new conductor. I’m

      The problem with #1 is that most garages only have one circuit for the outlets AND the garage door opener. Moving to 240v would fry the opener.

      Changing a 120v line over to 240 is likely also against code even if the physical cable can handle it. 120V cable is typically white/black/green, and the electrical code prohibits using the white one as a hot leg. That’s why 240V cable of the same AWG is red/black/green. The red & black legs both carry 120V.

        Code allows painting the white conductor black which is what i do. Or at least it did 10 years ago when I last checked.

          This.

          That said, it’s rare that only one or two outlets in a garage are tied to a breaker. Usually they’re all on one circuit in older homes, in my experience.

          If you can find a circuit like this, though, it’s perfectly valid. Many chargers made for 110V also have a 230V/15 or 20 amp mode. My Mother-in-law’s portable charger has a 230V NEMA 2-20 adapter that comes in the bag with it.
