Freescale is about to launch a new wireless charging chip that will be world's first solution capable of handling up to 15W. The chip uses the Qi technology and will be capable of supporting devices like the Apple iPad and Samsung Galaxy Tab, which have 12W power ratings, as well as be capable of charging phones more quickly.
The Apple iPad and Samsung Galaxy Tab have approximately 12W power ratings, which have yet to be addressed by existing wireless charging devices. The 15W spec will also enable mobile phones that have fast charging capabilities, a capability expected to grow rapidly in 2015, according to IHS analyst Ryan Sanderson who shared his thoughts on the news with EETimes:
I personally believe there is more value in a wireless charger at 15W that can charge multiple devices of different power classes in multiple scenarios than one that is just targeted at charging media tablets. If the solution can charge your media tablet (at 12-15W), your phone (with a choice of standard or fast charging) and a wearable device (which could be anything from 0.5W to 3W+) at the same time and manage this process, I see that as a valuable product.
