I'm not sure if that's the best example...

Kinda like saying that I have a bunch of very light indoor extension cords and you are wanting to run an outdoor high amperage device (both 110v in this example). Yea, the interface for both is the same, but one is going to be used far less often and require a much more expensive cable for a reason.

The girth of a power cable roughly scales with capacity though, and there are 3 common pin configurations

- 2 equal size blades

- 2 unequal size blades

- 3 unequal + ground pin

plus a fourth for 20A

- 1 vertical blade, 1 horizontal blade, 1 ground pin

USB-C cables have one form factor, which is what GP is talking about.
