why isn’t it ok? why???

Meme “the number of people who think this is an abomination” over a photo of a USB-A to USB-A cable, “but think this is perfectly acceptable” over a photo of a USB-C to USB-C cable, “makes me sick.”

    I had to look up, USB PD does work with a USB A port.

    That being said, I personally want to get to a single type of cable so any I get can be spares for anything I have, so I like USB c to be all around.

    That ALSO being said, I doubt I will ever get to all USB C.

    Side note, USB PD is awesome because I know it can do up to 240w. (Last I knew.) That is 48v at 5a, so I am not sure what they can do to squeeze out more wattage.

      USB PD is not specced for USB-A which is limited to 5V 2.4A. They had Quick Charge back in the day that got a little bit higher power using 9V but all the modern higher voltage high current PD stuff uses USB-C. The USB-A cables aren’t specced to be running 5A or more that PD uses.
