First Wireless Charging mobile phone Nokia Lumia 920 all set for launch tomorrow

Mobile phone maker Nokia will launch the next generation mobile phone Lumia 920 with wireless charging, first of its kind, on Wednesday in New York in collaboration with Microsoft.

Technology blog Verge said the Nokia Lumia 920 will support wireless charging, which is not confirmed. If true, this will be the first of its kind in the industry. Apart from this unique feature, the phone is said to be featuring a 1.5GHz dual-core processor, 1GB of RAM, with 32GB of storage.

What is Wireless Charging?

Wireless charging or inductive charging helps transfer energy between two devices within an electromagnetic field.  These chargers use an induction coil to create an alternating electromagnetic field while a second induction coil takes power from the electromagnetic field and converts it into electrical current to charge the battery in the phone. Recent research has allowed charging in distant objects using resonant inductive coupling.

Though wireless charging is less efficient and more expensive than usual charging, it holds bright future. Some of the early products using wireless charging include the Oral-B rechargeable toothbrush by the Braun company, which was launched in the early 1990s.

Hughes Electronics has developed the Magne Charge interface for General Motors to charge its EV1 electric car. Even the Chevrolet S-10 EV and Toyota RAV4 EV vehicles use similar charging system.

Apart from Nokia, Samsung is planning to launch wireless charging devices for its phones in near future.
