They are also configured for audio data transmission. Most of the vehicle interface currents on the car The current is very small, generally only 5V/ 0.5A. If you use the car's USB interface to give the mobile phone, then if the current does not meet the standard, the device may be damaged. In this case, the cell phone car chargers wholesale manufacturer recommends that the car owner buy it separately usb car charger.

The more usb ports, the slower the charging speed: in fact, the charging speed generally depends on the voltage, not on several usb ports, because the current is intelligently identified and does not interfere with each other.
