We can plug the usb power adapter into the cigarette lighter inside the car. After plugging in the plug, the indicator light lights up to indicate charging. This can only be charged when the car engine is started. It can also use the usb cable to convert the connector. Mobile phones, mp3, interface products can be connected to charge, especially convenient and practical compatibility. In the process of use, you need to pay attention to:

1. Once the car is turned off, it cannot be recharged because the battery of the car is used.

2. When the car is started at the ignition, it is also not connected to the charging. This is to prevent the transient current from being too high and the voltage is low, which affects the charging effect. Seriously, the device is burned out.

3. It is best to charge one to one. When multiple devices are charged at the same time, the power will be too large, causing the device to burn out.

4. It is best not to use the car charger during thunderstorms. Do not use it immediately after car wash to prevent excessive humidity in the car and cause component corrosion.

5. Pull out the plug in time after charging.

6. We usually look for the brand when buying, choose a well-known brand, remember not to pursue high current, do not buy three no products, the quality is difficult to guarantee, for security reasons must buy regular.
