Most of cars come with USB interface,and maybe more than one interface.Most people think it is no problem that using the USB interface on car to charge mobile phone or any other devices.This idea is wrong,because the USB interface on car is made for data transmission,most of USB interface current of car is far less than 5V/1A. If you use the USB interface on car to charge mobile phone or even tablet,the current is not up to the standard,then these devices will be damaged.All of you disapprove for these view,After all, the car comes with USB interface is convenient charging and saving money.
there are some Common errors in the use of car chargers.
We taken a test: In general,if the output current can reach 0.9A, it will have not any problems to charge mobile phone.Butit far from enough for 2.1A of tablet and 2A of Android phones,not along the current is about 0.5A of car.In addition,As part of the car system is difficult to identify some Android phones,if you using the USB interface on car to charge some of the Android phones,the current l be a drop to below 0.5A. So we Suggested that the car owners should buy a better car charger If there is a need for charging.
