An adapter is needed to charge your Mercedes-Benz electric vehicle at Supercharger stations. The adapter, approved by Mercedes-Benz, connects the NACS-equipped charging cable to the CCS1 port on your Mercedes-Benz EV and is used ONLY for DC fast-charging. The adapter is rated for 500 amps/1000 volts. Please read the User Manual before use. Do not use the adapter for AC charging (ex. home wallbox or Level 2 public charger). Mercedes-Benz has extensively evaluated and tested the recommended adapter to ensure the safety of use and its compatibility with your vehicle. Mercedes-Benz does not approve or endorse other aftermarket adapters. Customers may purchase the approved adapter through a Mercedes-Benz dealer. Any vehicle damage that is the result of using a non-approved adapter may not be covered under your vehicle’s warranty.

Mercedes-Benz EV drivers will be notified in early 2025 when adapters are available to purchase through an authorized Mercedes-Benz dealer.

The Tesla Supercharger network is integrated into the MB.CHARGE Public network, so ensure MB.CHARGE Public service is active in the Mercedes-Benz app (Manage Digital Extras > Charging > MB.CHARGE Public toggle switched to “Activated”). Next, confirm you have the adapter in the Mercedes-Benz app by toggling on the "NACS Adapter" under Charging Status & Settings. This will allow you to locate and route to Supercharger stations. At the station, you can start a charging session through your vehicle’s display or the Mercedes-Benz app. Connect the adapter to the cable, then insert the adapter into your vehicle and the session will begin momentarily. Please be aware that Tesla policy prohibits the use of third-party adapters that are not sold or distributed by an automaker.

If you have a Mercedes-Benz Fast Charging Adapter, click on “Charging Status & Settings” in the Mercedes-Benz app, then toggle on “NACS Adapter” when prompted. Also make sure your MB.CHARGE Public service is active. Your vehicle will now display NACS-equipped charging stations, including Supercharger stations, and Navigation with Electric Intelligence will automatically optimize your route to include charging station stops along the way. You may experience a delay of about an hour before the stations become visible in the app or vehicle display after you turn on the "NACS Adapter" toggle.

Not all Supercharger stations are accessible to Mercedes-Benz all-electric vehicles. Your vehicle’s navigation display or Mercedes-Benz app will only display accessible stations once you’ve confirmed in the app that you have the NACS DC Fast Charging Adapter. The station details on your vehicle’s display for stations that require an adaptor will show, “DC Fast Charging Adapter required. A Mercedes-Benz approved adapter is recommended.”

In some cases, the cables at Supercharger stations may be too short to reach the charging port on your Mercedes-Benz EV. If this is the case, please obstruct as few stations as possible, do not park horizontally or diagonally. Drivers must NEVER use an EV extension cable to reach from the charger to the vehicle.

Please contact your authorized Mercedes-Benz dealer if you are experiencing issues with your vehicle or adapter. If you have questions about the charging at Supercharger stations or your charging services, please contact Mercedes-Benz Customer Support 855-502-3851.
