Charge your Apple Watch in a flat position with its strap open, or on its side with the Apple Watch Magnetic Charging Dock. Your watch automatically goes into Nightstand mode when placed on the dock so you can also use it as your alarm clock. The Apple Watch Magnetic Charging Dock uses the same inductive charging connector that comes with Apple Watch. It charges both the 38mm and 42mm models. And it connects via the Lightning to USB Cable and Apple 5W USB Power Adapter.
