In my quest to decide on 14-50 or HPWC some people suggested getting the HPWC so that I can keep my EVSE that comes with the car in the car. But do I really need this EVSE in the car? Wouldn't I be stopping at super chargers or other chargers if I am on the road? Just wondering how many people need to keep the EVSE in the car vs just use it at home, and how often they actually use it. I also have a 16amp 14-30 EVSE J1772 I could put in the car instead and still save some money using the stock EVSE instead of the HPWC?
