It is not clear if the brick would use GaN or offer some special features. However, 35W suggests that this would be for mobile devices rather than Macs. You could quickly charge an iPhone 13 Pro Max (which supports up to 27 W) while still leaving enough power for an Apple Watch or AirPods. Multi-port chargers are not exactly uncommon in the third-party market, but they can be appealing if you stick to a formal solution. It is also uncertain when Apple may release the dual port power adapter. This is not the kind of product that would take screen time at an event like WWDC and there is no guarantee that it will debut alongside a higher profile device. While this apparent slip may imply an impending release, this debut could just as easily be months away.
