Re: USB-C for power
It is pretty standard these days to have a dock that on one end picks up supply power, and on the other end connects to the laptop, but also to whatever peripherals you want to run.
In most cases it means you have just one jack to connect for everything to be online, and as a bonus you will be able other people's power supplies when on location, even those from (gasp) Apple, and vice versa.
I'm all for USB-C power - it finally ended the racket of proprietary power supplies that has been around since almost forever. If your portable machine is modern enough to have a USB-C supply socket but needs more than the 95 or so Watt that most USB-C supplies can offer you must have an asbestos desk or knees - or ought to consider using a desktop instead.
