How does a car cigarette lighter work?
Explore the engineering of a car cigarette lighter through industrial CT scans, revealing an efficient analog design that operates without digital components.
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.

It's cool how elegant the design is that it automatically ejects when it's done heating up without needing a sensor and digital system to read and handle that action. It's also cool how a feature designed solely to light a cigarette has been adapted to power all sorts of other things. I wonder if these ports will be obsoleted in favor of only having USBs.
My electric car only has USB ports and no cigarette lighter, so I bet you're right about it being replaced.
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.
