May be the car's cigarette lighter power supply itself has a problem. Check the car fuse for damage and replace it if necessary. Summary: The above are the common reasons and solutions that cause the car USB interface to be unable to charge. In order to ensure the stability and safety of charging, the appropriate car charger should be selected, and the contact, voltage and current of the charger should be checked regularly, and the damaged parts should be replaced in time, such as the car charger and the car fuseDoes not charge properly
1, when the car charger can not be charged, there may be several reasons: the fuse of the car igniter is broken; Car charger contact is poor; Car charger output input voltage current does not support charging electronic devices; The connected data cable may be damaged. In addition, if you charge directly using the USB port in the car, it may be because the USB port is set to transmit audio data, and the current is only 5V/0.5A, which will cause damage to the phone.
2, the second possible reason is that the data cable is damaged. If there is a problem with the data cable, such as the data cable is damaged orDisconnect, then the car usb can not be charged. Need to replace a new data cable to solve the problem. The third possible reason is that the mobile phone charging port spring is relaxed, resulting in poor contact. If the car usb can not be charged, you can check whether the mobile phone charging port spring is relaxed.
3, the car charger output is unstable, most electronic products have a self-protection mechanism, to avoid high current damage to the device itself, it can not be charged normally. The quality of the charging device itself is problematic. The data cable used is damaged, resulting in the data cable can not be charged in the car and the mobile phone has a problem. Probably a phone chargeThere is a problem with the electrical interface, which causes the car to be unable to charge. The power supply to the cigarette lighter is abnormal.
