90% of people do not use the car charger, you use it?
Working principle of vehicle charger:
The 12V car cigarette lighter socket voltage into USB voltage 5V and the charging cable to charge electronic products. In general, the car charger is the 12V (car 12V, truck 24V) DC into 5 - 20V DC power for mobile equipment charging, characterized by low power consumption, simple and convenient.
1, the use of attention
Do not plug in the car before the start of the car charge, so as not to start the vehicle when the voltage damage to the car charge.
When the owner is in use, do not use strong chemicals, cleaning agents, strong detergent to clean the charger. Because this will seriously damage the function of the car charger.
The particular attention in the process of using the car charger will not arbitrarily throw, landing, beat or shaking the charger, and when the summer vehicle and long-term stagnation temperature inside the car when more than 45 DEG C do not use the charger, which will seriously damage the circuit board inside the car charger.
The car charger as one of the electronic products, the owner is in use process, should pay attention not because of careless water or long time when not exposed to humid air, which will result in its internal electronic components with different degrees of corrosion or oxidation.
The vehicle turned off should be placed unplug the car charger. Although 80% of the vehicles are vehicles pulled out after the key cigarette lighter to stop power supply, but also a lighter car is part of a continuous power supply.
2, purchase notes
葡京牛牛赌场 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.
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 the mobile phone navigation function is being charged, poor quality charger is not only unable to provide a normal charge will continue to decline.
葡京牛牛赌场 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.
