San Marcos, TX - Tesla Supercharger

About this record
Taken from the AFDC register, which covers publicly reported charging infrastructure across the United States. Home chargers and unreported private installations do not appear in it.
Port counts describe how the site is configured, not whether a given port is free right now. Check the operator's own app before setting out if you are relying on a specific charger.
