Carry around a 3,000 watt mains extension, because someone decided making USB C cables all support 100 watts was just too demanding, eh?

100 watt USB cables are a bit thick and unwieldy since they need to support a current of 5A. They also need better insulation, since they use a higher voltage (up to 20V).

If your phone can only charge at 10 watt (5V / 2A), why would you use a stiff, heavy 100W cable to charge it?

Well sure if it's for a airconditioned-hottub-phone, but I'm pretty sure a small 600 watt cable would be more cost effective here.
