Using Pi from USB power?

[Ice Rich]

Does anyone here run their Pi (specifically the 4) from USB port on their desktop? I've searched and there seems to be consensus of 'not recommended' but no real mention of what what will happen? Could it damage parts over time?

I thought the power adapter was a usb-c format thing anyway?

Yep it is and I have a usb (standard type) connected to desktop with the other end a usb-c for Pi. I don't know if this meets the requirements (power wise) for it though.

edit: I see what you mean and have edited my post
