Why can't car phone stand charge?

Car charger does not charge reasons:

1. When charging, the voltage is unstable, resulting in no charging

When the power is turned on, the mobile phone or other smart electronic products will generally open the power monitoring and detection program. If the program detects that the vehicle flush voltage is unstable, it prohibits the flush. When using the seat, there will be no program for detection, it is recommended to use the usb interface of the car audio computer system to charge, whether it is a line or a seat.

2, check whether the car charger parameters meet the charging requirements

Check the output voltage and current of the car charger, whether it supports its own digital products. Some parameters do not meet, such as the output current for 1A car to charge the tablet computer, it is not rushed into the electricity. This is caused by insufficient current, and a high-power car charger needs to be replaced.

3. Check whether the contact of the car charger is in good contact

The contact design of some car chargers is unreasonable, and there will be poor contact during the driving process, which leads to the discovery that there is no charge after arriving at the destination.

4. The power supply of the cigarette lighter itself is abnormal

If you replace a number of car chargers, mobile phones, etc., you can not normally use the car charge in your car to charge, at this time to check whether there is a problem with your car fuse.

5, the quality of the charger itself

There are many brands of car power supplies on the market, products are good and bad, and the price gap is large, if you buy shoddy products, not only can not be charged, but also it is likely to burn car fuses and digital products, and even may endanger personal safety. When buying a car charger, be sure to pay attention to the purchase of a safe and secure smart car charger!
