    I was about to say this doesn’t make sense, whose router is powered from a USB-C cable…

    Then I remembered that I bought cables to go from USB-C to barrel jack so I could plug my modem and router into a single USB power block instead of their individual wall warts.

      They make whole building lighting that runs off PoE. I’ve never seen it deployed, I don’t know why one WOULD do such a thing, but it always makes my head spin when I remember it exists.

        …I don’t know why one WOULD do such a thing…

        The biggest reason is that now you don’t have to pay electricians to run cables; you pay low voltage guys who are much cheaper and are probably already running g low voltage cable for network connectivity. In addition, each light can be addressable meaning you can have specific light fixtures do certain things.

        Source: I’ve seen it deployed.

          Interesting, seems like a big leap of faith for new builds but it makes sense if you assume you’ll always have the building, and this technology will always be alive.

      Some people set-up their mobile phones as temporarily-permanent hotspots.
      And then there was this mobile hotspot that used USB.
