The Apple Watch Magnetic Charging Dock was a 4.1-inch diameter, 0.5-inch thick charging pad for the Apple Watch that used the same inductive charging connector that shipped with the Apple Watch. The white base of the dock had a microfiber, padded texture. The polished-chrome charging disc was mounted on a hinge that could pivot from a flat position to a 45-degree angle.
According to Apple:
“With the Apple Watch Magnetic Charging Dock, you can charge your Apple Watch in a flat position with its band open, or on its side. When docked on its side, your watch automatically goes into Nightstand mode, 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 all Apple Watch models and sizes. And it connects via the Lightning to USB Cable and Apple 5W USB Power Adapter.”
The Apple Watch Magnetic Charging Dock has also shipped with Apple Watch Edition models and has been available since 2015 with a Lightning connector built into the base. As of 2020 it still shipped with a Lightning-to-USB (USB-A) cable.
This example is the standalone product with the original packaging.
