Sony working on double speed wireless charging
Sony is developing wireless charging technology that will cut the charging time in half, reports Japan's Nikkei. The new technology, which is due in the second half of 2014 will dramatically reduce the time for wirelessly charging a device taking it down to around one hour. Sony is able to achieve the reduction as by being able to successfully conduct electricity at 10-15 Watts, double the amount current wireless chargers are able to deliver.
The Sony device will fall under the latest Wireless Power Consortium international Qi standard. Currently Nokia, Samsung and others have developed wireless charging for their devices under the Qi branding, although it is not expected that these devices will be forward with the new Sony technology. It is possible, however, that future Sony devices that support the new format will be backwards compatible with the older standard.
Intel recently spurned the Wireless Power Consortium Qi standards and opted to join the Alliance for Wireless Power (A4WP) instead. Intel has been working on wireless charging that utilizes near-field magnetic resonance that don't need devices being charged to sit on an charging mat.
