What if someone uses all 4 ports simultaneously to charge new MBP?

    I read this possibility on Twitter: "Countdown to someone trying to charge their MBP faster by plugging power adapters into all four ports."

    On a serious note, should Apple add a disclaimer? For the record, I did order a new 13" Space Gray MBP with touch bar and only plan to charge it with one port at a time! :p

    I'm gonna assume it's a boring answer like "after the first USB c cable is plugged in, THAT is the one and only power cord and every USB c cord after that is just for data"

    But explosion...or creating a black hole. That's the fun answer

    The world officially ends.

    But seriously, someone at Apple has tried that.

    The OS will first pop up a screen asking why the hell you would buy 4 power cords. Then the case will expand to the 17" MacBook Pro.

    At least it'll be safe for someone who does actually try that!

    Yes. I'm pretty sure such things are part of the Thunderbolt 3/USB-C specification anyway.

    In terms of which one it picks, I'd suspect it's more complex than just the "first" one - it probably goes for the highest power one if they are different wattages.

    What I supposed above has been confirmed by an Apple support document:
