I have not tried any other adapters or cables than the NEMA 14-50, but I did experience that Neutral is not used by or relevant for the PMCC (or for any other EVSE, I guess).
Agree, as a travel option the PMCC is not an appropriate choice at all for the reasons quoted above, despite the "Mobile" in its name. As a home/garage car charger it is quite OK (the overheating is not a grave problem) but I would never spend that kind of money on it if it would not have been...
Very true, but the Porsche Mobile Charger Connect refused to operate from that same outlet before it was properly grounded. I guess I already know your opinion about the PMCC...
I am also keeping a Mustart TravelMaster as an emergency charger in the extra storage space under the trunk. It works well, but I was a little shocked (no pun intended) to find out it charges at full spec even from a 220 V outlet which did not yet have its ground pin connected.
A bit like the current mix of power supply:
- conventional electrical grid to homes and businesses in populated areas,
- high-voltage power lines into factories,
- gas-powered generators for homes in remote areas and for back-up purposes.
I have a 100 A line (on a 100 A breaker in the main panel) going into my garage where a sub panel has two 50 A breakers which each feed a NEMA 14-50 outlet.
