There are three reasons why you can't charge:
1, USB interface problem 2, charging cable problem 3, mobile phone interface problem you can check one by one, usually is the reason for the line. 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 to check the car charger output voltage, current, whether to support their 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 good contact Some car charger contact design is unreasonable, there will be poor contact in the process of driving, and lead to the arrival of the destination found that there is no charge.
4, the cigarette lighter itself is not normal power supply if you replace a number of car chargers, mobile phones, etc., 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.
5, the quality of the charger itself is now on the market of car power brands, product good and bad, the price gap is large, if you buy shoddy products, not only can not charge, but also is likely to burn car fuses and digital products, and even may harm personal safety. When buying a car charger, be sure to pay attention to the purchase of a safe and secure smart car charger! USB car charger USB car charger: usually also referred to as USB car charger. It takes advantage of the versatility of USB, which is widely used in various charging interfaces. Combined with the application in the car, the 12V DC and 24V DC in the car are converted into USB and the common DC 5V voltage of each charging appliance. In this way, the standard power supply and USB interface on the car can be used to charge DC 5V appliances. Such as: mobile phones, MP3, navigators, game consoles and other 5V DC electrical appliances. The price of USB car charge has an inseparable relationship with the specifications of USB car charge, which may look exactly the same, but the output is different, and the price is different. Usually, the greater the current, the greater the power, the higher the price. The price can be divided into cost price, factory price, wholesale market price and retail price. Here, from the user's point of view, we will roughly talk about the retail price. The price of each network sales platform ranges from 3-80, which is mainly different in the power and materials of the product.
There are three reasons why you can't charge:
1. The USB port is faulty
3. There is a problem with the phone interface
You can go through them one by one, usually because of the line.
1. When charging, the voltage is unstable, resulting in no charging.
