In a press release today the Wireless Power Consortium, custodian of the Qi wireless charging standard widely used in Nokia handsets, has announced it has added Resonance charging to their Qi protocol.

The Qi resonant extension will allow charging with higher efficiency and lower radio frequency interference than typical resonant solutions. In addition, the extension allows for multiple device charging and charging at longer distances, all while maintaining backward compatibility. 

For consumers, this means it will be possible to charge without worrying about the exact position of their devices so they can charge anywhere, safely and quickly. 
For companies, this means greater flexibility in designing products when integrating Qi in cars, furniture, chargers, and accessories.  


“Qi is the leading global wireless charging standard because its 190-plus member companies thrive in the WPC’s competitive-and-collaborative environment and are constantly innovating to produce the best wireless charging experience,” said John Perzow, Vice President of Market Development for the Wireless Power Consortium. “The WPC has created a standard that ensures safety and compatibility and frees OEMs to differentiate. That’s why Qi is used in more phones, tablets, cars, and products than any other wireless charging solution.” 

The Qi spec will maintain backward compatibility with the installed base of 40+ million devices and products worldwide, including the 60 models of Qi-compatible phones, tablets, and chargers sold today.

The first examples of the extension’s capabilities will be unveiled by WPC members ConvenientPower and PowerbyProxi at the WPC booth at the International CES in Las vegas today, at the SL-2 in the South Hall 3 lobby, located on the upper level.
