Marco, A somewhat common failure that I encountered was with adapters that were supposedly official ones, but where sideways strain on the adapter put enough force on the ultrasonic weld that it split open, leaving either the bottom with exposed pins in the vehicle inlet, OR the pins could remain stuck in the charging pistol, so the charger power pins were now exposed to the world. The design of the adapter had two plastic pieces, that captured all pins between them, but a break would leave the complete pins in either shell, when you pressed and glued the two halves together you'd have a working adapter again. This was with the ubiquitous "Tesla" adapter that allows a Tesla to charge from J1772 stations, but I am sure that the problem is not unique to that version. Cor.
