This is an ad for something CT-scan-related, but it contains a good breakdown of how an old car cigarette lighter works. And it has a couple interactive CT Scan explorers past the video.

    My first GPS came with a cigarette lighter plug.

    My next one came with a USB cable along with a cigarette lighter to USB adapter.

    I think most these days now come with a USB cable but no adapter.

    I’m now starting to see some devices come with USB-C cables.

      You’re still buying GPS devices? What’s wrong with your phone?

      Not judging - genuinely curious why some people buy them.

        Bought my first one probably 20+ years ago at this point.

        Bought my second one probably 10+ years ago when traveling abroad and it was more reliable and cheaper to have offline maps of the countries I was going to.

        We like to travel to places that often have spotty cellular coverage, if at all.

          Ah okay, I don’t go to places with spotty coverage all that often…and when I do I just download that part of Google maps onto my phone and it works just fine. And by “that part” I mean a significant part of my country! Small world here in Europe I guess.
