Check the battery: First, check whether the battery of the vehicle is working properly. You can check the battery voltage and connection. If the battery voltage falls below the normal range (usually 12 volts), the battery may need to be replaced.
Check the charging system: Check the vehicle's charging system, including the generator, voltage regulator, and associated wire connections. Make sure the generator is working properly and able to charge the battery. If any faults or damage are found, the relevant parts may need to be repaired or replaced.
Check fuses: Check the fuses of the vehicle, especially those related to the charging system. If you find a blown or damaged fuse, you may need to replace the fuse.
Seek professional help: If you are not sure how to solve the problem, or if the above methods do not solve the problem, it is recommended that you seek the help of a professional auto repair technician. They can make more detailed diagnoses and repairs.
It may be a problem with the charging port or the charging cable, you can try to replace a data cable. Generally speaking, the voltage of the USB interface on the older car is 5V\/1A, and some are even 5V\/0.5A, generally speaking, the use of this interface is used to receive audio data, and charging generally requires a higher current and voltage.
