What charge port do you have that isn't Tesla compatible with an adapter?

[Rebelgecko]

AFAICT, unless you're in San Francisco, Sacramento, or New York there is currently no adapter that will let a non-Tesla vehicle use a supercharger.

That's because much of the Supercharger network was deployed with the assumption of only supporting Tesla vehicles. If any third party charging network deployed NACS fast charging stalls in your area, they would absolutely be compatible with any CCS1 vehicle with an adapter.

Would something like a TeslaTap work with a 350kW charger? Or do new adapters need to be created?

[simondotau]

The most likely outcome is that third party stalls will either mimic Tesla's magic dock or over-provision with two cables per stall, or (most likely) have some ratio of NACS-only, CCS1-only, and CHAdeMO stalls based on demand.

Adapters like TeslaTap output J1772, not CCS, so new adapters will need to be created (like the Magic Dock).
