How to use car charger?

First of all, we want to understand what is the difference between the car charger and the commonly used charger, their difference is mainly the plug - the plug of the car charger is a cigarette lighter type, in the car to find the cigarette lighter (generally in the cab and the suitcase each one), plug into the plug (to plug in 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 light of the car charger. If it is on, it is entering the charging state.

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

What need to pay attention to the use of car charger?

1. Pull out the car charger after extinguishing. 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 electricity is not enough to worry about, but for a long time to go down, it will still have a certain impact on the car battery loss, so we had better be able to develop the habit of unplugging the car after charging.

2, car charger should not overload use. Many owners in order to use convenient in the cigarette lighter socket with power dispenser or inverter, can be an interface allocated into multiple interfaces, for multiple vehicle electrical equipment used at the same time; Or convert 12V direct current on the car to 220V AC power supply, which can be used for small power household appliances. In this small series to remind you that the power interface of the cigarette lighter is the maximum tolerable power, the maximum acceptable current of the circuit of the cigarette lighter is generally 10A(there are 20A), according to the output voltage of the cigarette lighter 12V to calculate the maximum load power of 120w(there are 240w), the total power of the electrical appliances can not exceed the rated power of the cigarette lighter, Therefore, try not to use high-power equipment or use multiple on-board electrical equipment at the same time, so as to avoid excessive load, which may cause fuses to be blown, or even damage the vehicle circuit or electrical equipment and other risks.

3, not what car charging can be used directly. Car chargers aren't exactly new technology, but there are a lot of small steps that can be taken. First of all, it is mainly provided by the cigarette lighter interface, voltage must also be converted from 12v to 5v, but the current copycat car charging throughout the market, which is not only easy to cause short circuit phenomenon, in serious cases can even lead to mobile phone or car spontaneous combustion, therefore, all buy car charger must be careful.

4. Avoid using car chargers with poor quality. Now more and more vehicle equipment, many owners like to find some cheap "gadgets" on the Internet, do not know the quality of these products is uneven. Summer car exposure temperature is high, winter temperature is low, in this harsh temperature environment, some quality of vehicle equipment is easy to appear some unexpected problems. These situations, when they occur, are likely to affect your car's electrical system and blow a fuse. So please try not to buy some poor quality vehicle electrical products.

5, the use of car charger should avoid high temperature irradiation. Now the weather is getting hotter and hotter, when charging the mobile phone in the car should avoid being placed in the direct sun, so as to avoid the mobile phone temperature is too high and dangerous, try not to connect too many external interfaces on the car cigarette lighter.

6. Not all USB ports are suitable for charging. In fact, most of the USB ports in the car limit the interface flow, which also leads to the current of the interface is divided into 5V/0.5A and 5V/1A. At this time, if the wrong interface is selected, it will not only easily lead to hot mobile phone, but also long charging time, and eventually will seriously affect the life of the mobile phone battery.
