Yep, this is a common issue since Tesla uses a different charging standard (NACS). Some newer Tesla chargers support J1772 charging with the right settings, but if yours doesn’t, you’ll need a J1772 adapter to make it work.
Yeah, the J1772 adapter is your best bet. I use one with my non-Tesla EV, and it works just fine. Just make sure the adapter is rated for your charging speed to avoid any issues!
