Thanks for your inquiry! To charge an Apple Magic Keyboard, connect a USB-C to Lightning cable to the Lightning port on the back of the keyboard, then plug the other end into a USB port on your Mac or a USB power adapter; the keyboard will automatically charge while connected. -Christy

From the details we have on it there is no mention of it being detachable. Additional support would be available for it through Apple's website directly though. -Josh
