I mean if you tend to plug things in at the same computer a lot it's pretty easy to always plug things in right the first time, even when not looking because you just kinda know what way it's meant to be. And laptops usually have all theirs pointing the same way so you know one you know them all. If something has text on it, it's usually oriented in such a way that when plugged in you can read it. Or they have a little face and you know which way the face is meant to be facing

I have a similar "power" and while I'm not flawless, it's only really new or unfamiliar devices/computers that trip me up. Or plugs that don't actually have any identifying features and/or unusual ones
