How to use the car charger correctly, the service life of electronic devices will be longer? What to pay attention to?

How to use the car charger?

First of all, we have to understand what is the difference between the car charger and the commonly used charger, their difference is mainly in the plug - the plug of the car charger is a cigarette lighter type, find a cigarette lighter in the car (generally one in the cab and one in the trunk), insert the plug (to plug it in to the end, hear the click).

Second, connect the other end to the phone or other digital device you want to charge. According to different charging products, configure the corresponding data cable.

Finally, observe the LED indicator of the car charger, and the light is on to enter the charging state.

It should be noted that when charging the corresponding device, please note that the charger can only be used after the car engine is started! Otherwise, when the car ignites, the voltage reduction of the car battery will affect the charging effect and even damage the car charger.

What should I pay attention to when using a car charger?

1. After turning off the heat, pull out the car to charge. After the car turns off, some owners may not remember to unplug the car, although the car charger has no current output at the moment, the loss of power is not enough to worry, but for a long time it will still have a certain impact on the loss of the car's battery, so it is best to develop the habit of unplugging the car charge in time after charging.

2. Do not overload the car charger. Many car owners will equip a power distributor or inverter on the cigarette lighter socket for ease of use, and can assign one interface to multiple interfaces, which can be used by multiple on-board electrical equipment at the same time; Or convert 12V DC power on the car to 220V AC power supply, which can be used by low-power household appliances. Here Xiaobian reminds you that the cigarette lighter power interface has the maximum bearable power, the maximum current acceptable to the cigarette lighter circuit is generally 10A (also 20A), according to the cigarette lighter output voltage 12V to calculate, the maximum load power is 120w (also 240w), the total power of the electrical appliances can not exceed the rated power of the cigarette lighter, so try not to use high-power equipment or use multiple on-board electrical equipment at the same time, so as not to have excessive load, causing the blown fuse, Even damage to vehicle circuits or electrical equipment and other dangers.

3. Not all car chargers can be used directly. Car chargers are not actually a new technology, but there will still be a lot of small doorways. The first is that it is mainly provided by the cigarette lighter interface when it takes electricity, and the voltage must also be converted from 12V to 5V, but the current cottage car charging is all over the market, which is not only easy to cause short circuit phenomenon, but even lead to spontaneous combustion of mobile phones or cars in serious cases, therefore, buy car chargers must be cautious.

4. Avoid using car chargers that are not of good quality. Now there are more and more on-board equipment, and many car owners like to find some cheap "gadgets" on the Internet, and they are familiar with the uneven quality of these products. In summer, the temperature in the car is high, and the temperature is low in winter, and in this harsh temperature environment, some in-vehicle equipment that is not of good quality is prone to some unexpected problems. Once these situations occur, it is likely to implicate your car's circuit system and blow the fuse. Therefore, please try not to buy some poor quality car electrical products.

5. The use of car charger should avoid high temperature irradiation. Now that the weather is getting hotter and hotter, you should avoid placing it in a place exposed to direct sunlight when charging the mobile phone in the car, so as to avoid the danger of the mobile phone temperature being too high, and try not to connect too many external interfaces to the car cigarette lighter.

6. Not all USB ports are suitable for charging. In fact, most of the USB interface in the car limits the interface traffic, which also leads to the current of the interface is divided into 5V/0.5A and 5V/1A, at this time, if you choose the wrong interface, it is easy to cause the mobile phone to be hot, and the charging time becomes longer, and eventually it will seriously affect the life of the mobile phone battery.
