The charging cable on the 2016 MacBook Pro is USB-C both ways, allowing me to plug the MacBook into itself. What happens if I do this?

    Since nothing special happens when you connect it to another macbook pro I expect nothing happens when you connect it to itself, I just don't dare to try it with mine :# – dennismuijs Dec 21 '16 at 10:35

The new MacBook Pros have circuitry in all USB-C ports so that the charger can be plugged into any port.

Plugging a two-way USB-C cable will just make the device think that it's charging as technically there is a power source coming from one of the ports into the other.

It doesn't actually charge anything but the reporting is what's making the battery icon show 'charging'.

We just tried it with my friends laptop It charges itself (well... it thinks it does)


It probably will detect it as a short circuit and shut down. I would not do it, if I were you.
