Nowadays, the car charger has become popular in most car owners. However, the quality of car chargers is uneven, and many car owners do not know how to use them correctly. A small car charger can cause huge losses if there is a problem. The car charger converts the 12V voltage of the car cigarette lighter socket into a 5V USB voltage, which is used to charge the mobile phone and other devices. Its characteristics are small power consumption, simple and convenient, and low price. Although this configuration is simple and easy to use, it can cause damage or even danger if it is not properly operated.
Precautions for use
1: Before starting the vehicle, it is best not to insert the car charger or connect the power supply to the mobile phone to avoid the unstable voltage generated by the vehicle starting to damage the charger and the mobile phone.
2: When the car charger has been used for a long time, do not use chemicals or detergents to clean the charger. Wipe it with a wet tissue and dry it to avoid damage.
3: Pay special attention to not throwing, landing, knocking or vibrating the charger at random during use. When the vehicle is exposed to the sun in summer and the temperature inside the car exceeds 45 degrees Celsius, do not use the charger temporarily, otherwise the circuit board inside the car charger will be seriously damaged.
4: The car charger is an electronic device. Do not leave it in a humid environment for a long time to avoid different degrees of corrosion or oxidation of its internal electronic components. If you accidentally spill water on the charger while driving, wipe it off immediately to avoid damage to the board.
5. After the vehicle is turned off, the car charger should be unplugged. If it is plugged into the power connector for a long time, the contact between the two may be corrupted and difficult to remove. Although 80% of the vehicles are powered by the cigarette lighter after the vehicle is unplugged, some of the car’s cigarette lighters are continuously powered. Therefore, it is necessary to pay attention to purchase a car charger with overload protection function, 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 to cause damage or even combustion.
