The official Tesla CCS (Type 1) adapter is not yet available in the US, but it's compatible with most Model 3 cars and all Model Y vehicles, and then select S/X models (I think).

I found this particular adapter on Harumio, a Korean parcel forwarding service. They'll do the shopping for you, and charge you appropriately to forward it to the US. There are numerous such services and I recommend searching r/Tesla or r/TeslaModelY (or any number of other EV forums) for links.

I was encouraged by what I saw today.
