> And now you have USB-C-Apple to keep you guessing.

Pick a random USB C cable today.

Now tell me:

- what speed data does it support?

- how much power can it delivery?

- can it do video over USB C?

Now pick a random USB C powered device like sone Sony headphones or low end devices that come with a USB A to USB C cord. You try to charge it with a USB C to USB C cable and find it doesn’t work because the device doesn’t actual support USB C power delivery



Now plug in two random computers with USB-C. What happens?

Does one start to charge the other? Which one? Does the result change every time you plug the cable in?

Ah, the wonders of USB-C :D


Is this dangerous to try stuff like that? I'm curious now!

I wonder what happens if I connect the 2 charging USB-C ports of my MacBook together


USB-C devices have a "priority" number: Which number is up to the manufacturer. That number determines which device will be the host. There is a process for Power Role Swap to be initiated by the user, but I have never done this myself :)
