Now, in a follow-up tweet, he has claimed that accessories like AirPods, the MagSafe Battery Pack, and the Magic Keyboard/Mouse/Trackpad trio would also switch to USB-C in the "foreseeable future.".
A switch to USB-C would result in a more universal connectivity standard and satisfy regulators, as a wide range of tech products are equipped with USB-C ports, including many Android smartphones and even the latest MacBooks and iPad Pro, iPad Air, and iPad mini models.
Other Lightning port products (e.g., AirPods, Magic Keyboard/Trackpad/Mouse, MagSafe Battery) would also switch to USB-C in the foreseeable future.
