Tesla Model S: Wall plug adapter error - Charge rate reduced

Tesla Model S (2012-2024) Owner's Manual / Consumer Information / Troubleshooting Alerts / Wall plug adapter error - Charge rate reduced

Plug adapter fully into Mobile Connector and retry

Your Mobile Connector is unable to communicate with the wall plug adapter. Because your Mobile Connector cannot monitor the wall plug adapter temperature, charge current is automatically reduced to 8A.

It is recommended that you try the following troubleshooting steps:

1. Unplug your Mobile Connector, including the wall plug adapter, completely from the wall outlet.

2. Make sure the connection between the wall plug adapter and the main body of your Mobile Connector is secure.

  1. Disconnect the wall plug adapter completely from the main body of your Mobile Connector.
  2. Fully reinsert the wall plug adapter into the main body of your Mobile Connector by pushing it into the socket until it snaps into place.

3. Try charging again by plugging the Mobile Connector, including wall plug adapter, fully into the wall outlet.

4. If the alert persists, try using a different wall plug adapter (see steps above to make sure the adapter is fully connected to your Mobile Connector).

  1. If the alert is no longer present, the issue is likely with the wall plug adapter you were using previously.
  2. If the alert persists, the issue is likely with your Mobile Connector.

It is recommended that you obtain another wall plug adapter or Mobile Connector as needed, based on the troubleshooting steps above.

In the meantime, you can continue to charge with the same equipment. The charge rate will be reduced, as charge current will be limited to 8A while this condition persists.

You can also try charging your vehicle using a Tesla Supercharger or Destination Charging location, all of which can be located through the map on your vehicle's touchscreen display. See Maps and Navigation for more details. Additional third-party charging stations may also be available in your area to help you to pinpoint the issue.

For more information on troubleshooting Mobile Connector status lights and charging issues, refer to the product's owner's manual.
