What should I pay attention to when using the charger

 

 

1. Do not insert the car charger before the car starts, so as not to damage the car charger when the vehicle starts.

 

 

2. Do not throw, knock or vibrate the charger when the vehicle is in use. Do not use the charger when the vehicle is parked for a long time in the summer and the temperature inside the car exceeds 45 °C. This will seriously damage the internal circuit of the car charger. board.

 

3. The car charger should be unplugged after the vehicle is turned off. Although 80% of the vehicles have the function of stopping the power supply after the key is removed, some of the car's cigarette lighters are continuously powered.

4. If it is not used for a long time, if it is exposed to humid air, it will cause different degrees of corrosion or oxidation of its internal electronic components.

 

 

5. Do not use the cleaning agent or detergent to clean the charger. This will seriously damage the function of the car charger.

 

What should I pay attention to when buying?

 

Select products with overload protection

The USB specification requires no more than 5A for current overload protection. The reason why the car charger needs overload protection is because when the output current is too large and exceeds its normal output value, the life of the charger component will be shortened or the temperature will be too high, resulting in damage or even burning. Therefore, the car charger in the car must have overload protection measures.

 

 

Select products with output current above 1A

 

 

The input voltage of the car charger on the market is basically 12V-24V, the output voltage is 5V, and the output current is about 1A~4A. However, some "three no" or "cottage" products generally have a phenomenon of charging current imaginary. If the phone is charging while providing navigation, the inferior charger will not only provide normal charging but will continue to drop power.
