What I’m talking about is, for example, a keurig coffee machine having two differently shaped prongs where one prong is bigger and wider than the other, so you have to insert the wider prong into the wider port.
However, something like a phone adapter doesn’t have this, and the two prongs are the same size and shape.
Why is this?

You will often see both prongs the same on things that are DC powered where things are hitting a transformer first. But for AC powered things it’s often beneficial to know where hot vs neutral is. The smaller prong on the right is the hot.
