Starbucks Corp. announced on Tuesday it is starting a U.S. rollout of wireless charging stations in its coffee shops. It said in a press release that about 200 locations in the San Francisco Bay area have been equipped with Powermat charging stations. They stations are located on tables and counters where devices can be placed to be charged wirelessly. It said any phone is capable of being charged this way when a Powermat Ring is plugged into it, which will be available at Starbucks stores to purchase for $9.99 US or be loaned out. Starbucks said expanding this throughout the U.S. will follow, and it may be brought to Europe and Asia next year. The release did not mention Canada. Starbucks Canada spokeswoman Carly Suppa said in an email that timelines for Powermat charging stations outside the U.S. are not currently being publicized. The technology is the result of a joint venture between Procter & Gamble Co.'s Duracell division and Powermat Technologies Ltd. The latter is a New York based company that recently appointed former BlackBerry Ltd. CEO Thorsten Heins as its chief executive.
