I have a Nexus 5x (Android phone). It uses a USB-C charging cord. When I plug my USB-charging cord into my phone and into a PC I own, the PC charges the phone (as expected). When I instead insert the USB-C cord into my phone and the other end into my MacBook Pro, the phone charges the MacBook.

This is backwards to me. How do I charge my phone from my MacBook?

  • actually that is not possible. to charge your mac you need at least 12 Volt, while the Phone can only produce 5 Volt. Double check your observation and let us know why do you think it is the way.

  • Does the same behaviour occur if the MacBook Pro is plugged in to charge?
