I did some serious driving and Tesla camping this weekend in some really hot weather. I pulled into a RV site at 10 pm with 7% with my LR RWD. It was over 90 degrees F outside. Plugged in gen2 UMC w/ 14-50 connecTor at 224 VAC and 32 Amp. I needed to charge to at least 90%, sleep in the car with the AC running. The cars prediction was nearly 11 hrs. I was like... "Uhh.. I'm not going to be here that long."

In the end it worked out because the temp dropped in the middle of the night and the car started charging faster... However, I see the need to pull a full 40 Amp from 14-50 mobile EVSE which is approx 20% faster than 32A. In general this would a win in any situation where a 14-50 plug is used away or at home.

Tesla gen2 UMC only supports up to 32 Amp. I looked on the web but only saw 1 such option on Amazon and the J1772 EVSE had issues with quality and melting. The other options I see are buying a Tesla 14-50 corded gen 2 HPWC or some similar corded Juice Box or clipper Creek unit. Problem is that these units are huge! Not too portable.

Any suggestions for a 50 Amp rated (40 Amp continuous) 14-50 corded mobile EVSE?
