The CAN SR will allow Roadster to connect to Tesla's "destination chargers" (Model S/X wall chargers). In the Cincy area, it looks like Hilton Cincinnati Netherland Plaza has two chargers (up to 64 A), and closer to Mason the Envision Cinemas bar and Grille also has two (up to 80 A).
You can also pair the CAN SR with a Model S mobile connector to connect into virtually any outlet with the right fitting. Example: I've used my CAN SR+Model S mobile cable to connect to a NEMA 10-30 (dryer) outlet.
Or you can use the CAN JR to connect to any J1772 charging stations, like any other EV. Usually 30 A.
Good luck!
