I currently own several USB-C devices (Laptop, phone, Remarkable, Switch, portable monitor) and I can't tell you how nice it is to only have to bring a single charger with me when I travel. The biggest thing holding me back from getting an iPhone is breaking this pattern.
You wouldn't real this patter with an iPhone: you can still use the same charger, with Lightning USB-C cable. In fact, this is the official cable you get these days with new models.
