I don't think there are any restrictions. I think j1772 might just work with an adapter (adapt from the nacs plug to the j1772 plug)

I thought tesla even made a j1772 native wall connector.

There are some restrictions.

I had the foolish idea of installing a Tesla charger at home to charge my Bolt. I’ve been unable to ever use it.

The wall charger works fine with Teslas. My car and adapter charge fine at Tesla superchargers.

But the home Tesla charger refuses to charge my Bolt. (Yes I disabled vehicle restrictions and tried all sorts of combinations of settings for weeks before giving up. Tesla support was useless of course)

Restriction or bug, same difference.

    Really gross. I have a gen 1 charger and it's dumb as bricks. Basically just a giant relay.

    I guess I could see why you might want to restrict who can use your charger, but I really prefer the "dumb as bricks" version I currently have.

At least a few years ago, they would openly recommend it for non-Teslas.

I thought NACS brought some changes to Level 1 and 2 that aren't backwards compatible with J1772? I know there's an oddball voltage in there so you can put a NACS charger on a lamppost where J1772 would require a transformer; but I didn't think there were protocol issues too.

    J1772 is 120V or 208-240V. Those are by far the most common voltages in the US. (208 is what you get when you take a US 3 phase system and connect to two phases - this is somewhat common and most people don't know or care that their apartment is wired like that). I have seen other voltages at industrial sites, but I wouldn't expect that in a lamppost.

Can confirm. I've used an adapter to charge 2 different non-Tesla cars off my wall connector.
