If you use the UMC that comes with the car and plug it into a 14-50 outlet, then you will charge at 32 amps. The UMC maxes out at 32 amps. You would need a Clippercreek, Juicebox, or Grizzl-E plug-in type chargers to get the full 40 amps.I am interested in the Nema 14-50 for charging at mu in laws. I’m curious what the max rate of charge is on one? I prefer day trips and not over night trips lol
Here is chart to show different charging miles using the UMC.
