The Wireless Power Consortium (WPC) announced that the latest version of the Qi specification now makes it possible to deliver 15 watts of power to mobile phones that support wireless fast charging. This means that the time required to wirelessly charge a devices will be decreased.

Several manufacturers already offer wired fast charging for their devices, providing as much as 60 percent charge in as little as 30 minutes. The latest Qi specification empowers them to extend this speed to wireless charging as well.

"This release marks an important milestone for Qi, introducing the first higher power class and paving the way for our members to address more demanding applications with products that work seamlessly with the installed base of Qi-compatible products," said Menno Treffers, chairman of the WPC.

In addition to the new Qi specification, the WPC also approved the test procedures and tools needed to verify that fast charging products are compliant with the new Qi specification, as well as being backward compatible with allexisting Qi products.

The new specification is initially available only for members of the Wireless Power Consortium. It will be made available as a public document at a later date.
