Paging Dr Howard, Dr Fine, Dr Howard... okay, back on topic... I have all of these below but I've not used them yet, and don't know if they are needed with the expansion of the Supercharger network. However, for the expenditure of $20 or so, you can set yourself up in all of them, and then pay nothing monthly and be ready in case you ever want to use one of them somewhere across the country:
Blink Needs CC
Chargepoint Needs CC
EV Connect
EVgo Needs CC $4.95
Greenlots Needs CC $5
Semaconnect Needs CC $10
