The Magic Keyboard combines a sleek new design with a built-in rechargeable battery and enhanced key features. With an improved scissor mechanism beneath each key for increased stability, as well as optimized key travel and a lower profile, the Magic Keyboard provides a remarkably comfortable and precise typing experience. It pairs automatically with your Mac, so you can get to work right away. And the battery is incredibly long-lasting ? it will power your keyboard for about a month or more between charges.
