A St. Louis-based TikTok creator named Triciarosemary5, known for content about hair care, fashion, and recipes, recently sat down in her car, held her phone charger up next to a slightly larger, rounder port on her dashboard, and asked her followers the question: “Is this just another charger that’s fatter?”
She was not trolling. She genuinely did not know what the second socket was. And the internet lost its mind.
The video, posted on April 21, racked up more than 3,800 views and dozens of comments ranging from helpful explanations to mild existential crises from older drivers who suddenly realized they were living in a different world. The moment was funny, but underneath the humor was something genuinely interesting: a young woman who had grown up with USB ports had never needed to know what a cigarette lighter socket was. And why would she?
This was not ignorance. This was a generational gap made visible in a 10-second clip, and it turned out to be more revealing about the pace of automotive and cultural change than anyone expected.
What Is That “Fatter” Port, Exactly?

The mysterious socket Triciarosemary5 spotted is the 12-volt accessory outlet, which most people over a certain age know by its original name: the cigarette lighter socket. The cylindrical design was first patented back in 1919, and by 1956 it had been standardized by the Casco company into the port that became a fixture in virtually every car on the road. The official specification was codified in 1960 and the basic design has barely changed since.
For most of the 20th century, this port existed for exactly one purpose: to heat a small metal coil that a driver could use to light a cigarette without fumbling for a match. Cars came equipped with a matching lighter that popped out when it was hot enough. Ashtrays were built into dashboards and door panels as standard features. Smoking while driving was not just common; it was practically designed into the vehicle.
That world is now almost completely gone, and for many younger drivers, it might as well have never existed.
The Slow and Quiet Disappearance of the Cigarette Lighter
The decline of the cigarette lighter in cars closely tracked the decline of smoking in American culture. As fewer people smoked, automakers began removing the heating element from the socket while quietly keeping the port itself, which they rebranded as a 12-volt power outlet. The socket stayed because it turned out to be genuinely useful for all kinds of accessories that had nothing to do with cigarettes.
Toyota held on longer than most major manufacturers, fitting its last factory-installed cigarette lighter into a 2017 Sequoia before finally redesigning the port as a pure power outlet. Most other brands had made that shift years earlier. Today, some automakers still offer a “smokers package” as an optional add-on, but it is far from standard.
One commenter summed it up neatly: the socket used to be for a cigarette lighter, but now it is just for power, or an optional upgrade for buyers who specifically want the old functionality. The socket survived. The lighter did not.
What You Can Actually Use It For Today
Here is the practical part, because the 12-volt port is still genuinely useful even if you have never held a cigarette in your life. Portable tire inflators, 12-volt coolers, small fans, dash cams, and older GPS units all rely on this port for power. Small inverters that plug into the 12-volt socket and convert the output to a standard AC outlet are a popular accessory for road trips, allowing travelers to power laptops or other devices without needing a built-in outlet.
Commenters on the original video rattled off a solid list of uses: fans, coolers, air pumps, flashlights, radios, and inflation devices. One commenter delivered the most nostalgic use case, describing how drivers used to plug in an adapter to power a small TV with a built-in VHS player to keep kids entertained on long drives to Grandma’s house.
That comment alone was a time capsule.
What This Moment Actually Teaches Us
Beyond the laughs, this video is a small but useful reminder of how quickly technology resets our baseline assumptions. Triciarosemary5 grew up in a car culture defined by USB-A ports, and now USB-C. To her, a charging port is slim, rectangular, and universally recognized. A round socket with no obvious phone cable compatibility is just a mystery.
Meanwhile, older drivers watching the video were confronted with the realization that something completely ordinary to them, something literally built into every car they ever rode in as children, had become invisible to a younger generation. One commenter summed up the emotional whiplash by writing that he was officially old. Another joked about fighting dinosaurs with the tool that used to plug in there.
The real lesson here is not that younger people do not know things older people know. That has always been true and always will be. The lesson is that technological change happens fast enough that a standard feature can go from universal to unrecognizable within a single generation, and we rarely notice until a 10-second video makes it impossible to look away.
Triciarosemary5 got the last word anyway. When a commenter asked how she had made it this far in life without knowing what the socket was, she replied simply: “Because of you,” followed by a heart-eyes emoji.
Honestly, a great answer.
