How can we charge batteries without wires, batteries unlike routers are not data driven devices. Actually Duracell has launched an Inductive Charger which charges batteries using electromagnetic induction. A charging station sends energy through inductive coupling to an electrical device, which stores the energy in the batteries. Because there is a small gap between the two coils, inductive charging is one kind of short-distance wireless energy transfer.
The charger, is wireless, but you need to put either a power clip, or sleeve on your device to get it to work. It can charge up to 4 devices at a time which are now limited to BlackBerry, Motorola and Nokia phones but they do show an iPhone and iPod touch on the web site.
The Procter & Gamble-owned Duracell has apparently licensed the WildCharge pad and stuck its own logo on the corner, presumably in the hope that such a trusted name will drive sales of the new-ish technology.
