Nowadays, car charging is easy for some people in the car, because the most models are equipped with a USB charging port or cigarette lighter to charge. But, do you know that it is far from being as simple as plugging and unplugging? Now, let us tell you about the things you need know about car charger!
1.It need not use car charger when there is a USB interface on the car.
Many people think that the USB port on the car can be plugged directly to charge.However, it is wrong!
Since most of the USB ports in the car are set for audio data transmission, most of the vehicle’s interface current is only 5V / 0.5A. At this case, if the current is not reached to the standard of charge, your equipment will be a degree of damaged.
2.Charging current must be enough big”
What does it mean? Simply put: the current output of the car charger must greater than the maximum rated input power of the cell phone.
For example, an car charge with output 5v/2.1A, it use for mobile phone(maximum rated input power 5V/1A) to charge, which is 1A for the phone, and if using for tablet(maximum rated input power 5V/2A), 2A will use for the tablet, and it will be completed in a shorter time and the battery is fully charged. But if output charge current is 5V/0.5A for the same mobile phone, the input is 0.5A, that is not very slow, and it will be severely hot and damage the mobile phone battery for a long time.
After understanding this, you need to buy a car charger with a high output and high quality. Don’t smash mobile phone because of unqualified car charger.
3.Be sure to take out the car charger after the car is turned off, otherwise it will damage the battery of car.
The battery of car will be damaged if you often did not remove the car charger after the vehicle is turned off. Ordinary family car vehicles will be powered off after the flameout. Even if the special model is not powered off after the flameout, It has not a current output or have no effect on the battery if the charger is not connected to the charging device.
4.More USB ports, slower charging
Normally, the speed of charging depends on the voltage and not on the number of connected devices.
5.After charging with USB port, the electric quantity is not rise, instead of fall.
Some people are used to charging the phone while navigating, it may be happen above case. Originally, most of the car’s USB interface was designed to transmit data. Although it was shown to be charging after connecting with phone, but the current was only about 0.5A.
When you are listening to a song or navigating with a mobile phone, the consumed amount of power consumed is actually greater than the amount of charge. Therefore, there will be no rise, instead of fall.
Therefore, when choosing a car charger, we should pay attention to the following 3 points:
First, we must choose car charge with with overload protection function.
second, choose the product with output current above 1A.
Third, it is also important to choose a regular manufacturer !
