Two Rock Station

Of its 2 ports, 1 is DC fast and 1 is Level 2. DC fast ports deliver direct current straight to the battery and are the ones used for quick stops on longer trips. Level 2 ports are 240-volt AC chargers, typically used where a car is parked for an hour or more. That is about half of the California average of 3.7 ports per station. The registry lists 2 connector types: J1772, the standard Level 1/2 AC connector; CCS, Combined Charging System — the J1772-based DC fast connector. Pricing as reported to the registry: “Level 2 Free; DC Fast Charger $10 per hour”. The site is listed as a fire station location.
