Apple - What is "BC 1.2 port"?

Battery Charging spec

BC 1.2 is an abbreviation for (USB) Battery Charging (revision) 1.2. I'm no USB specs specialist so I can link some abstracts/files only:

  • USB Battery Charging (Wikipedia)
  • USB Battery Charging Revision 1.2 (PDF)
  • Overview of USB Battery Charging Revision 1.2 and the Important Role of Adapter Emulators
  • Overview of USB Battery Charging Revision 1.2 and the Important Role of Charger Detectors

Basically it's a USB 3.0 port with some extra features to detect devices that can make use of charge currents beyond the standard 900mA.
