A: No. (Need to know the current size of the USB interface of the car)
< br \/ >
explain
1. The USB interface of the car is to transmit audio data, and the current of the USB interface of the car is both 5v\/2.1A and 5V\/0.5A. The input current required by many mobile phones is 5V\/1A, 5v\/2.1A car USB of course is no problem, this time it can give the mobile phone input 1A current, can give the tablet computer input 2A current. If it is 5V\/0.5A, it is obvious that the current will not meet the standard, and charging the phone in this case will not only take a long time, but also make the phone hot.
2. In the process of converting the 12V voltage of the car from the cigarette lighter to 5V, the car charger must go through multiple steps such as voltage regulation, rectification, overload protection, etc. If the inferior originals and materials are used, it is easy to short-circuit or even spontaneous combustion. It doesn't matter if a car charger breaks, if it destroys the phone or even the car because of the car charger, it is really not cost-effective. Car charging is not high-tech, but there are still real and fake.
3. Don't look at the car charger is a small object, we should pay attention to the size of the voltage and current of the supporting equipment when purchasing, for example, the standard input voltage of the general portable and handheld terminal products is 5V\/700MA, and the iphone is 5V\/1A. The output voltage of different cars is also different, for example, the output voltage of cars is 12V, and the truck is 24V. Therefore, the universal car charger is suitable for 12V cars, and the car inverter is suitable for truck use.
