Apple Insider reports that Apple has shown interest in creating an all-in-one data and power cable that could be used to charge and transfer files between unique devices like iPhones and Macs.



The concept was highlighted in an Apple patent application published by the U.S. Patent and Trademark Office and discovered by AppleInsider. The proposed invention, entitled "Power Adapters for Powering and/or Charging Peripheral Devices," is a continuation of a concept that dates all the way back to filings from 2001, and among its inventors is former iPod chief Tony Fadell.

The filing describes "improved techniques for powering and/or charging peripheral devices through a data transmission lines." The accompanying illustrations show a number of possible configurations for charging a device like an iPhone or iPod from the same wall plug that powers a portable Mac.
