I think that's not the best approach. As for me, I am not worrying about adapters, but waiting for the Tesla SuperChargers to be opened up to to Lexus.
You can currently use any Tesla Supercharger equipped with a Magic Connector. You can find which Tesla superchargers are equipped with this on the online Tesla website.
In So-cal, there’s only one but a few more in Nor-cal. Otherwise yes, will have to wait for Lexus to officially release an adaptor sometime in 2025 to be able to charge with Tesla.
