The second reason is that the car charger parameters do not meet the charging requirements.If the current is not enough, you need to replace the high-power car charger.
The third reason is that the car charger has poor contact.The contact design of some car chargers is unreasonable, and bad contact will occur during driving, leading to the failure of charging after arriving at the destination.
