6 months agoTheoretically you could build a male to male contraption from multiple adapters and a cable. Also you could be providing too much current to a device, however this is specific to the combination of adapter, cable and power supply you use.
Of course those exist, but that does not make them standard compliant. Same goes for power supplies that don’t do handshakes. That’s not an issue if you exactly know what you need them for, but they’re not meant for the general public because you can use them wrong.
