1. First of all, eliminate the influence of mobile phones: plug the car charger into the cigarette lighter port and check whether the indicator light is displayed normally. Then charge different mobile phones to see if the car charger can be used to charge other mobile phones, if it can, it is the reason for the mobile phone itself;
2. Eliminate the impact of the car charger: two tests are needed here, one is to replace a new car charger or a normal car charger used by others, plug it into your car, and charge your mobile phone to check whether the case can be charged to the phone. The second is to plug your car charger into the cigarette lighter of someone else's car, charge your mobile phone, and check whether it can be charged normally under the circumstances;
3. Eliminate the impact of cigarette lighter: If you replace multiple car chargers, mobile phones, etc., you can not normally use the car charger in your car to charge, at this time to check whether there is a problem with your car fuse.
The reason why the mobile phone charger can not charge is because the mobile phone charger can convert the 220V AC into the current and voltage acceptable to the mobile phone, and the car charger needs to be designed according to the special nature of the car circuit, the circuit and charging interface of different models are different, especially in the circuit voltage and current requirements are higher.
Therefore, on-board charging can only be achieved by using a charger suitable for your own car.
If you use a car charger to charge the charging efficiency is very low, may be due to the charger circuit design problems, it is recommended to use a better compatibility of the original charger or the same brand of charger.
At the same time, it is also necessary to pay attention to the change in the amount of electricity when the car charger is charging, the change in the amount of electricity when the charger is charging may be caused by the poor quality of the charger or vehicle problems, it is recommended to replace or repair in time.
Possible reasons are as follows:
1, may be a mobile phone failure, mobile phone system failure will lead to battery display problems, this problem is easy to solve, restart
2, check the phone voltage problem, voltage instability will lead to abnormal charging, use wireless charger or reinsert the phone
3, check whether it is the charger problem, put on another charger to try, if it can be charged, it means that the quality of the car charger is the problem, replace it.
Mainly 厡 because the voltage level is different. Since China's civil voltage is the single-phase power supply of 220V, the power supply of the charger supporting the mobile phone manufacturer is mainly based on the voltage level, and most of the car power supply is 24V DC, so the car power supply is not chargeable.
This situation occurs because the voltage of your car charger is unstable, and the instability of the conversion voltage is too large, resulting in the inability to detect the charge, which is replaced
