How to Repair a Cigarette Lighter That Has No Power?
1 Answers
Below is an introduction regarding the reasons why a cigarette lighter may have no power, as well as how to resolve and avoid such incidents: 1. During use, plugging and unplugging may cause the curved spring plate of the external device's plug to deform, resulting in loose contact after insertion and affecting conductivity. The symptom is intermittent connection. Solution: Adjust the angle of the curved spring plate on the plug. If this doesn't work, it is recommended to seek assistance from a 4S shop. 2. How to avoid such incidents: (1) After using an external device, leaving it plugged into the cigarette lighter before turning off the engine can undoubtedly cause trouble. At the moment of vehicle startup, external devices on the cigarette lighter are prone to burning out due to the high current surge, especially MP3 players and USB drives, which are highly susceptible to issues. Therefore, it is advisable to unplug the device after use and plug it back in only after the car has started. (2) Depending on the vehicle's settings, some cigarette lighter power sources do not turn off when the vehicle is turned off, and many vehicles still have power. Thus, leaving external devices plugged into the cigarette lighter for extended periods is not a wise choice. The best practice is to plug in the device when in use and unplug it after use, avoiding prolonged insertion into the cigarette lighter socket to enhance the safety of external devices.
