Apparently, this Nokia accessory can wirelessly charge not only smartphones
So, it turns out that a Nokia wireless charging plate, which is meant to be used with handsets like the Nokia Lumia 920, Lumia 820 and the likes, can charge the batteries of other gadgets as well. A Reddit user posted this photo of an electric toothbrush supposedly being charged inductively as it sits right on top of the accessory.
