My work laptop can charge fine with the current spec USB-C PD that supplies up to 65W. Macbooks have had this benefit for many years now as mentioned by another poster. As I said, it just needs better cable labelling because they are not all equal.In that case, I suppose that a USB-C plug would be able to charge a laptop. Initially, I found that hard to believe. After all, most laptops are charged by 19 volts DC or thereabouts, not 5 volts, so a switch to USB would mean more current, and a need for thicker wires.
