The CCS Combo 1 adapter has received domestic safety certification (KC) and can be used only with chargers that support the CCS Combo 1 charging standard among public quick chargers. If you use the CCS Combo 1 adapter, you can charge up to 300A, but the charging speed may vary depending on the capacity of the charger, charging conditions, and vehicle condition.
Therefore, the CCS Combo 1 adapter can only be used in public fast chargers with a rated output of 300A or less, which are currently distributed in Korea. Please be aware that it is currently not available for public quick chargers exceeding 300A due to parts that require additional progress, such as testing for use of the fast charger and consultation with the charger operator. Tesla is not responsible for any problems resulting from the use of public rapid chargers exceeding 300A.
