1. Charge directly using the USB port on the car
< br >
The USB interface in the car is actually set for audio data transmission, the current of this interface is generally 5V\/0.5A, if the current and voltage used by your phone is higher than this standard, it will cause damage to the phone.
< br >
2. Charge electrical appliances regardless of interface
< br >
Many like to use the car charger, but please note that the car charger output current can not be less than the maximum rated input power of the mobile phone, such as an output 5V\/2A car charger, to a maximum rated input power of 5V\/1A mobile phone charging, the car is charged to the mobile phone input is 1A, to the tablet computer input is 2A, can be fully charged in a shorter time. If the opposite, not only the charging time will be longer, but also cause the phone to be seriously hot, which will cause damage to the phone battery for a long time.

3. Use multi-connector data cable to charge multiple mobile phones at the same time
< br >
As we all know, many friends who do sales do business now have more than one mobile phone, some less than two more than three, in order to facilitate the one-time charge of several mobile phones, which will cause serious pressure on the vehicle battery, as we all know that all the electric energy in the car comes from the battery (battery), long-term such charging will damage the battery life, more than worth the loss.
< br >
The above three situations are what we often do and do not pay much attention to, in order to effectively eliminate the emergence of these phenomena, the detective summarizes several principles for everyone to choose a car charger:
< br >
1. Try to choose the car charger that uses the cigarette lighter interface
< br >
At this point, I think many friends will do so, the reason is that the cigarette lighter supports a larger current charging port, which is a lot of insurance compared to the USB interface.
< br >
2. Choose products with overload protection function.
< br >
This function is just like the safe used at home, preventing short circuit or poor contact caused by instantaneous current overload, effectively preventing the phone from being damaged.
< br >
3. Select a product whose output current is more than 1A.
< br >
At present, almost all smart phones support fast charging function, like Huawei, Apple, millet mobile phones basically support super fast charging, so the larger the current means the faster the charging speed, you can choose according to your own mobile phone specifications.
< br >
4. Choose regular products with guaranteed quality.
< br >
This point does not need to do too much explanation, all safety based, because the use of inferior products caused by the damage of vehicles and mobile phones, will not receive claims, serious words will also cause vehicle spontaneous combustion and other accidents, must pay attention to!
