MWC 2013: LG shows off world's smallest wireless charger, WCP-300

LG Electronics has introduced the world’s smallest wireless charger at the Mobile World Congress (MWC) which is going on in Barcelona, Spain. The device called WCP-300 is only 6.9cm in diameter and LG says it has been designed with portability in mind. The charging area is 1.7 times wider than that of LG’s previous generation wireless charger and the charger is compatible with a standard 5-pin micro-USB charger. WCP-300 uses electromagnetic induction technology and is Qi certified by the Wireless Power Consortium. Electromagnetic induction produces a magnetic field that in turn generates an electric current to charge the batteries in devices which are placed on the charging pad.
