Good news from the world of wireless charging. Mobile power Qualcomm joins the Wireless Power Consortium at. Until now, it was the “enemy” organization called Alliance for Wireless Power.

So far, QI and A4WP were not compatible with each other, the change of emphasis Qualcommm could in some circumstances that a common, better standard arises in the not too distant future. 172 companies have already joined the Wireless Power Consortium, the QI standard has been criticized from time to time, because (depending on coil and frequency) were delivered only 5 watts, which is not sufficient to larger devices in a reasonable speed boost.

Both the Wireless Power Consortium, and the Alliance for Wireless Power are developing solutions to charge devices over a greater distance, may also have been located by the Alliance for Wireless Power decided to up to 24 watts of power while the wireless is Power Consortium sets at 15 watts, for example, this would realize the wireless charging of notebooks.

Both standards also differ. The solution of the Alliance for Wireless Power allows you to charge devices with different power requirements, while the QI solution is designed to be efficient: it gives the device the power it needs and then switch off the power supply when charging is completed. The exact background for Qualcomm’s move are unclear. From the user’s point of view, one can only hope that by the end sets an industry standard that provides customers with maximum flexibility.
