Back in the 80s, I had a device that was powered by a 3.5 connector. This same device had another two 3.5 connectors for the headphones and microphones.

Somehow, I got through that time without ever having plugged the power into the microphone socket. I am not that careful.

We have a Lenovo Yoga laptop, the power and headphone sockets are about the same diameter and next to one another. Thankfully mis-plugging hasn't caused any negative hardware issues, just occasional bewilderment.
