I am interested adding a couple of USB ports for charging only. Has anyone done this? I am so tired of replacing the lighter adapters after1-2 months. I want something hardwired. I was thinking of something to replace the existing lighter with. Solutions?

Consider a computer USB hub. However, here is the problem.

Most USB ports cannot handle more than 10 volts input. I think the norm would be around 7.5 volts using a wall wart.

If one could figure out how to limit the input 12 volt automobile power to 5 to 9volts with a voltage regulator, then the USB hub could be hardwired into the vehicle and only a person's imagine would limit where and how it is mounted in the cabin.

I know there are ways to limit the voltage but not sure how to do it. Most others here are smarter than me so hopefully they will chime in.

This project would be quite inexpensive.
