Black Woven USB A to USB C Cable with 66W Watt Display - 1 meter

Everyone has that "good charger" in the house, the one that seems to get your phone from 4% to 100% in record time. But it's a bit of a mystery isn't it? Why does one charger work great while another doesn't seem to budge at all. It has to do with whether that charger supports USB Quick Charge, and of course the output current ability and the length and quality of the cable used. All things that an electrical engineer could work out with a multimeter and some notepaper - but who has time for that!
