Are you kidding? It isn’t obvious you are. Your Tesla came with one, it’s mandatory that all EVs sold in USA are compatible with J-1772 chargers. Hence Tesla provides the adapter.
SAE J1772 Charging Adapter $95.
I only wish Tesla would provide the NEMA 14-50 adapter to the mobile charger unit with ALL Tesla vehicles. They used to, I got mine, but I understand that at least the 3 and Y only get the 110volt lead for some time now.
What? I am not asking for an adapter. Let me try this again:
I wish Tesla sold the J-1772 wall connector on their website so I could buy one to install as a destination charger to supplement an existing Tesla wall connector while retaining the same aesthetic. That way a non-Tesla can charge and all of the wall connectors have a similar appearance.
