Follow the headline link and scroll through the images. The first one shows an open MacBook, with an iPhone and Apple Watch laid on either side of the trackpad. Both devices were wirelessly charging.
True, the devices would get in the way if you were trying to actually type on your Mac, but if you were doing something else and wanted a quick charge, your open MacBook would make a convenient Qi charger. And would mean one less thing to pack for a road trip (when road trips become a thing again).
The second image is even better. It shows a bunch of Apple devices stacked on top of a closed MacBook. Presumably all of them were charging, though I’d assume multiplestacked devices would slow down the charge time proportionately. But it looks like there are multiple coils, so maybe not?
It’s a patent, not necessarily something in the works, but I do think it’s an interesting idea.
