The charging port doesn't break from plugging in the cable, it happens because the headphone cable gets pulled at angles and usb-c isn't good at handling the stress from. I've literally had this happen. And yes, Apple's dongle IS one of the best usb-c dongles. They have always sold it dirt cheap as a way to assuage the people that were angry at the headphone jack removal. I am surprised they haven't raised the price after all these years; it has to be sold at a loss at this point.

The charging port (aka USB-C port) isnt going to break because you occasionally plug in a cable into it.

It absolutely can.

Engineers disagree.
