[Jasper]

The reasons for a cigarette lighter not having power are: 1. Long-term use with frequent plugging and unplugging, leading to loosening of the contact springs; 2. Repeated plugging and unplugging and improper use causing a short circuit, which burns out the fuse. The method for using a cigarette lighter is: 1. Insert the cigarette lighter into the car's power socket; 2. Press it down firmly until the heating element reaches the required temperature, and it will pop out automatically; 3. After use, return the cigarette lighter to the power socket. Precautions for using a cigarette lighter include: 1. The cigarette lighter has a dedicated power line connected to it and should not be mixed with other circuits; 2. It should be inserted and removed vertically, without shaking; 3. Avoid using electrical devices with excessive power on the cigarette lighter; 4. After lighting a cigarette, the lighter should be reinserted into the socket; 5. External devices should be promptly unplugged after parking.
