Starbucks announced on Wednesday that it is installing Powermat wireless charging in its 200 stores in the San Francisco Bay Area.

After conducting pilot tests for the past two years, the global coffeehouse chain is officially launching the service to its stores.

"We are thrilled to offer our Bay Area customers the next level of convenience with Powermat wireless charging. This first market installation is a first step towards a national deployment of this amenity in our stores," Starbucks Chief Digital Officer Adam Brotman said in a press release.

The Powermat Spots are placed in the tables and counters where customers can charge their devices. Devices that don't have wireless charging capability can also enjoy the service by purchasing or borrowing "rings" that are available in the store.

"The availability of Powermat Spots in Starbucks is transformative for San Francisco Bay residents who no longer have to worry about making it through their day with limited battery power," said Ran Poliakine, CEO of Powermat Technologies. "They know that the nearest charge is only as far away as the nearest Starbucks."

Starbucks partnered with AT&T and Google for the development of the wireless charging technology. AT&T said that it plans to offer wireless charging in airports, restaurants and hotels as part of its move to expand to other businesses.

 "This is not something that's going to happen overnight, but it's going to become more and more a part of consumer's mind-sets as they get comfortable with this type of technology," mobile device division director Jeff Howard told the New York Times.

Thorstein Heins, former BlackBerry CEO, was named CEO and chairman of Powermat Technologies, according to Businessweek.

Powermat wireless charging is expected to be deployed across Starbucks stores in the United States, and probably in Europe and Asia too, within a year.
