Daily use horse force car charger - car charger

The development of the times, the progress of science and technology, increasing per capita income, the living conditions of the masses of the people more and more substantial, as the communication activities and walking activities of large area into people's homes. When it comes to mobile phone and car, although they have a world of difference, but the two products have a certain correlation. Don't brag.

Today, the phone's power storage capacity is not as good as one day, when people drive a car when the phone suddenly cut off will have a significant impact, delay things. So, this car charger equipment will spread to most of the owner of the hands, but the vehicle charger quality is uneven, and many owners do not know how to use the right one, but there is a problem, it will bring great loss to you.

First, the working principle of car charger
This stuff is to convert the 12V voltage into the car cigarette lighter socket USB voltage 5V, then link the power line for charging the mobile phone. Under normal circumstances, the car charger will 12V (car 12V, truck 24V) DC into 5 - 20V DC charging for mobile devices, characterized by low power consumption, simple and convenient, cheap.
Although the configuration is simple and easy to use, but if the improper operation will lead to damage to electronic equipment, and even dangerous.
Note 1: before the vehicle is best not to insert the car charger, or the power supply to the phone, so as not to start the car when the unstable voltage damage charger and mobile phone.
Note two: when the car charger used for a long time to become dirty, do not use strong chemicals, cleaning agents, strong detergent to clean the charger. Wipe with a wet paper towel and dry, so as not to cause damage.Note three: in particular, pay attention to the use of the process do not throw the car charger, landing, knocking or vibration charger. In particular, the summer sun was exposed to the vehicle, the car temperature of 45 degrees, temporarily do not use the charger, which will seriously damage the circuit board inside the car charger.

Note four: car charger is an electronic device, the owner in the use of the process, do not put it in a humid environment for a long time, in order to avoid its internal electronic components caused by varying degrees of corrosion or oxidation. If you accidentally spilled water on the charger should be removed immediately and dry, so as not to cause damage to the circuit board.

Careful use of car charger is on the one hand, on the other hand, it is also necessary to pay attention to the purchase of products with overload protection function. USB specification for current overload protection requirements shall not exceed 5A. The need for overload protection is due to the fact that when the output current is too large and exceeds its normal output value, the life of the charger will be shortened or the temperature is too high to cause damage or even burn. So in the car charger must have overload protection measures.

Two, select the output current 1A or more products
The input voltage of the on-board charger on the market is basically 12V - 24V, the output voltage is 5V, and the output current is about 1A~4A. But part of the "three noes" or "copycat" products are generally charging current vacuity phenomenon. If you are using a mobile phone navigation is charging, not only can not provide poor quality rechargeable battery charging will continue to decline.
To buy the regular manufacturers through certification of products, do not buy and use three products, otherwise the quality problem of no complaints. Especially not freeloaders buy 20 dollars below the current price of the brand, car charger of the mainstream domestic brands in the 20-100 yuan, buy, buy a Chinese labeled marker that licensed.
