If your car USB port isn’t charging your phone, the problem could be with the port, the cable, or even the phone. Not all car USB ports are designed to charge phones, or power peripheral devices at all, so there’s a chance that you’re dealing with that type of situation.
Power management settings in your computer may be disrupting your USB ports. USB Selective Suspend can deactivate a USB port when not in use in order to save battery life, but can also sometimes disable the port when you’re trying to use it. When this happens, you can go into Power Options and turn off the setting.
Remember, when your USB port is not working, you need to:
Make a physical check.
If necessary, make a physical repair to the port.
Reboot Windows.
Check the Device Manager, uninstall the USB Host Controller.
Disable USB Selective Suspend power saving option.
Is there a fuse for USB port in car?

Is there a fuse for the charging system?
The primary alternator fuse (or fusible link) will blow whenever there’s excessive current flow due to a short circuit or other malfunction. When that happens, the charging system will no longer work as it should—and you’ll begin to notice a variety of problems. An example of a primary alternator fuse.

What happens if you replace a 20 amp fuse with a 30 amp fuse?
Replacing a 20 amp fuse with a 30 amp fuse could cause wire conductors to overheat and catch fire if a load (or total electrical loads) greater than 20 amps are placed in that circuit. The wire conductors are able to safely handle the designed 20 amp loads but exceeding that limit is asking for trouble.
