Starbucks Bows Powermat Wireless Charging in 200 Bay Area Stores

Starbucks launched Duracell Powermat wireless charging Wednesday in about 200 San Francisco-area stores, the coffee retailer said in an announcement. It marks the first step in the company’s "strategic plan" to offer Powermat throughout the U.S., and "to explore rollouts in Europe and Asia within the year," it said. Bay Area stores have designated areas on tables and counters where customers can place their compatible devices and charge them wirelessly, it said. Customers also can buy Powermat "rings" for $9.99 that instantly upgrade any phone to wireless charging compatibility, it said. Alternatively, the rings can be borrowed and returned on a per-visit basis, it said.
