The interface is different and cannot be used directly.
The applewatch has the ability to charge wirelessly, making it the first Apple mobile device with wireless charging. The Apple Watch uses a MagSafe-style wireless charger. It magnetically attaches to the back of the applewatch and is then charged by induction. Although it works in the same way as existing wireless chargers on the market, wireless charging can still bring a lot of convenience for a device that may need to be charged every day.
