Weird as heck plugs look like mini clothes dryer plugs.
Single split phase is standard in US homes. Practically all homes should have access to 240v by utilizing both "hot" legs.

The number of wires required for 120v and 240v are the same. You get 240v by connecting what would be the neutral wire on a 120v circuit to the other hot leg. You only need an extra wire if you want both 120v and 240v available on the same outlet (even then you only need 3 wires because you could use a hot and ground for 120v, but that wouldn't be as safe or meet code).



I had a high power 120v AC unit that would blow the standard 15A breaker constantly. There was an unused 240v 20A outlet nearby that I converted to 120v by replacing the 240v 20A breaker with a 120v 20A. It simply connects one of the wires to neutral (ground) instead of the other hot leg.



This is why I'm doubting ProDigit's lack of 240v access. As long as there is sufficient room in the breaker panel, there should be access to 240v. There is even a way to get 240v using a Y extension cord connected to two 120v outlets that are on opposite electrical legs. They come premade, or some people make their own.



There are plenty of reasons not to buy an expensive EV, but lack of 240v access is rarely a big problem because adding 240v is relatively easy, and 120v is often sufficient.
