After a wave of WWDC 2018 announcements, Apple made a quiet move, one that hardly anyone would have noticed. The company has replaced its 29W USB-C power adapter and introduced a brand new and revised edition that will supply up to 30W. The power adapter is actually designed for the 12-inch MacBook, the notebook that only relies on a single port to get the job done.

However, aside from being used with notebooks, the USB-C power adapter can also be used to fast charge devices like the iPhone and iPad models that can take advantage of the fast USB-C charging speeds. To be honest, even we’re are confused as to why Apple would make such a move as it appears very irrelevant. The charging times for the 30W USB-C power adapter is not going to be introducing a significant reduction for how long the device has been plugged in for.
