Not if you need 200w power to run inference.

USB-C can do up to 240W. These days I power all my devices with a USB hub, even my Lipo charger.

Have you seen a device that can supply 240w and act as a data host? Or is the 240w only from dedicated chargers?

I haven't seen one, but I also don't tend to use it for anything other than a power supply, so I wouldn't know. Since the standard supports it, though, it's just a matter of the market needing a device like that.
