I've got a pile of them here where the pilot wire failed in the cable not far from the handle. Just saying that the wall connector isn't much more money and is substantially more durable. The mobile connector has about 2-3 volts loss at 32A, while the wall connector is less than half that. Then there's the horrible NEMA 14-50 outlet to have to put your trust in, usually another volt right there!
It's crazy to me that people will spend tens of thousands for an EV, then want to cheap out and spend as little as possible on an EVSE. Hopefully people aren't also cheaping out on tires!
