USB1.0 and 2.0 have an output voltage of 5 volts and a maximum current of 0.5A. How to use USB: Insert the USB into the car's USB port. Turn on the device power to use it, and you can also copy MP3 music from a computer. Precautions for USB use: The USB flash drive also requires driver loading during use. If the USB flash drive or mobile phone is occasionally not recognized, try reconnecting it. If the USB flash drive is not used for a long time, remove it promptly to avoid accelerating the aging of the USB flash drive. Additionally, the host system frequently reads and writes the USB flash drive, which can affect the host's operating speed. Keep the USB port clean and tidy. If there is corrosion, water stains, small debris, or other foreign objects in the USB port, it may cause the USB flash drive to fail to connect properly.
