The car charger and the charging equipment contact is poor, the car charger voltage is unstable, the car charger itself quality problems will lead to the car charger is not charged, the details are as follows: car charger and charging equipment contact is poor. Because the vehicle usually wobbles during driving, the charging interface is thrown off, resulting in no charging without connecting to the power supply.
The voltage of the car charger is unstable, and the battery protection mechanism of the charging device works, resulting in charging failure.
Sometimes the output of the waiting car charger is not stable enough, and most electronic products have a protection mechanism to prevent the level of current from damaging the device itself, so it cannot be charged. The quality of the car charger itself leads to charging failure.
