The point is that USB-C is used by a LOT of devices that are NOT iPhone and that draw significantly more power, therefore its reasonble to explore standardizing any decive that can fit the specs wattage limitations. The more devices that can be charged from the same cable and plug would solve several problems not the least of which is reducing environment waste. I have a bag at home scores of AC to DC adapters and cables.
