You can still use your existing charger at home if you buy a Tesla-to-J1772 adapter.
There's a shop in California that makes an adapter called the JDapter Stub. Basically, you plug this in first into the Tesla charger you have at home, wait about 30 seconds, and then you plug this JDapter stub into the Taycan or any other car with a J1772 port. Done. No need to change out your existing home level 2 charging setup.
