Many people are accustomed to charging their mobile phones in the car, but after a while, they find that the power of the phone is getting less and less, and even the phone is overheating. Although it is not clear about the specific situation, but because the mobile phone would automatically shut down afer the power die,so we just continue to charge the phone. Today, I am here to tell those friends who do this often, don't do it again, or the consequences will be quite serious!
First, calculate an account for everyone. When the mobile phone is charged by the USB port in the car, it will also consume fuel. It will reduce the total mileage of about 3.8 liters of gasoline by about 0.48 kilometers, which means that the fuel consumption is increased! After conversion, the cost of charging in the car every hour is about 1.3 RMB. If you look at the cost of one hour, you may feel better, acceptable! But do you know how long the phone`charging will take in the car? In fact, this is not a good deal! Secondly, when charging in the car, these aspects are not done well, not only will the phone not be charged, but also damage the phone battery!
1. Directly use the USB interface that comes with the car
The USB interface in the car is only used for audio data transmission and is not suitable for charging mobile phones. Moreover, the output current of this interface is only 5V/0.5A, which is far from the requirement for charging the mobile phone. If the interface with current and voltage is not up to standard is used, the mobile phone will be overheating, and the mobile phone battery will be damaged. .
However, many domestic cars currently provide USB interfaces that are compatible with mobile devices such as mobile phones. Most of these interfaces are placed under the armrest box and the rear exhaust air outlet, with a current indicator, which can be used to charge the mobile phone.
2. No interface when using car charger
But now most people are very professional in charging in the car, and generally do not charge directly with the USB interface inside the car. I like to use the car charger, but please note that the current and voltage output of the car charger is also required, that is, it cannot be less than the maximum rated input power of the phone.
For example, an output 5V/2.1A charging interface charges a mobile phone with a rated input power of 5V/1A. The car charging interface inputs 5V/1A to the mobile phone, which is used to charge the tablet. It is 5V/2A, so it can be fully charged in a shorter time. On the contrary, the charging time will not only become longer, but the mobile phone will be severely burnt. In the long run, the mobile phone battery will be damaged.
3. Use the USB interface that comes with the car to charge, how can it not rise and fall?
The first point mentioned above also said that the USB interface of the car comes out because the output voltage and current are too low, and when the phone is running, there is software running on the back of the phone, which also consumes power. When the charge is not used. When there is a lot of electricity, of course, it will consume the original electricity!
Proper use of the right car charger will not only make charging more efficient, but the process will be safer! Therefore, pay more attention when purchasing a car charger.
1. Buy with overload protection.
2. Purchase output current above 1A.
3. Please purchase regular, quality-assured products.
