Becase some devices require a signal on their comm pins to negotiate the correct voltage to charge the device. Also some devices are dicks and needs a proprietary signal in order for it to charge. Looking at you sony.

    Whats weird is that my usb c wall powered hub will charge devices on its own if I plug it into a computer (or sometimes an android phone) first and then unplug it and plug it into the device I want to charge
