Wireless chargers in 2012!

With all the tech revolution - wireless broadband, wireless phone, etc; now it's the time for the wireless charger to take place ( at least in 2 years time).

Japanese electronics firm Fujitsu have developed a wireless recharging system which uses magnet technology. The system will be capable of charging the batteries of mobile phones, digital cameras and laptops without the need for leads. It can charge batteries which are several metres away and could lead to "wireless charging hotspots" in public places. The wireless recharging system will charge batteries 150 times faster than the usual time needed, and it just gets better....Fujitsu are also looking into applying a system to power up electric cars.

This "world first" works by sending electricity across magnetic fields between the wireless charger and electronic device. A slim power receiver and manufactured prototype mobile phones with wireless charging have been developed. The firm have claimed that the prototype mobile phones can charge anywhere within the power-transmitters range, with 85% efficiency. Tests found that the performance of the chargers depended on the size of the transmitter's coil; the optimal coil size for charging three devices took only 10 minutes.

Fujitsu have said, "This technology paves the way to integrating compact wireless charging functions into mobile phones and enabling multiple portable devices to be charged simultaneously without any restrictions on their position with respect to the charger."

The firm are hoping that the product will be on sale in 2012!
