As per title really, I cannot find out on the website how these are charged. I gather they have no batteries, presumably they have to plug into some sort of charger, but not specified anywhere that I could find.
Thanks
Magic Keyboard delivers a remarkably comfortable and precise typing experience. It’s also wireless and rechargeable, with an incredibly long-lasting internal battery that will power your keyboard for about a month or more between charges.¹ It pairs automatically with your Mac, so you can get to work right away. And it includes a woven USB-C to Lightning Cable that lets you pair and charge by connecting to a USB-C port on your Mac.
