How does a car cigarette lighter work? (www.lumafield.com)

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.

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.
