If your Mi 18W Car Charger Pro is overheated, please refer to the following troubleshooting steps:
1. As soon as you notice that the car charger is overheating, unplug it from the car's power socket and remove any devices connected to it;
2. Place the overheated charger in a well-ventilated area and allow it to cool down completely before attempting to use it again;
3. Once the charger has cooled down, carefully inspect it for any signs of damage such as melted plastic, burnt smell, or discoloration. If you notice any damage, discontinue use of the charger and consider replacing it;
4. Ensure that the car's power socket or USB port is functioning correctly. Sometimes, issues with the power source can cause chargers to overheat. Try using the charger in a different car or power source to see if the problem persists;
5. If you were charging multiple devices or using a high-power device with the charger, consider reducing the number of devices connected or using a lower-power device to reduce the load on the charger.
If the above troubleshooting methods can’t resolve the issue, please contact our local official service center or your seller for further assistance. They will help you in this regard.
