LG Electronics introduces the world's smallest wireless charger at the Mobile World Congress at Barcelona. The smallest wireless charger, WCP-300, is only 6.9cm in diameter and company claims it is designed with portability in mind.

Despite its tiny size, it doesn't compromise with power. The charging area is 1.7 times wider than that of company's previous generation wireless charger and is compatible with a standard 5-pin micro-USB charger.

The WPC-300 uses electromagnetic induction technology and is Qi certified by the Wireless Power Consortium. The electromagnetic induction technology produces a magnetic field that in turn generates an electric current to charge the datteries in the devices that are placed on the charging pad. The Qi certificate ensures that the product is compatible with all smartphones that support the Qi standards.

"Wireless charging is the holy grail of smartphone user convenience," Dr. Jong-seok Park, President and CEO of LG Electronics Mobile Communications Company said in a press release.

"With the WCP-300, LG was able to deliver both portability with top-class charging capabilities in a device no larger than a typical beverage coaster," he added.

In the U.S. market both smartphones; LG Spectrum 2 and LG Nexus 4, supports built-in wireless charging right out of the box, eliminating the need to purchase separate covers.
