Back in June, Starbucks and Powermat announced plans to bring wireless charging to the coffee giant’s chain of cafes. Six months later, that rollout is kicking off in earnest with help from AT&T, and roughly 200 Starbucks stores now offer the option to quickly charge your smartphone while you recharge with a little caffeine.

“We were pleased with the customer response to the pilot tests we conducted over the past two years and we now expect an even greater level of customer satisfaction as we set forth to offer wireless charging capability on a national scale.”  said Starbucks chief digital officer Adam Brotman.

For now, the initiative is focused entirely in the San Francisco Bay Area, though the plan is to keep expanding. At participating locations some tables and counters are now clearly marked for wireless charging with small black circles. If your device is already compatible with Powermat, which uses the PMA standard, just place it on the circle to charge. If not, Starbucks will sell a charging “Ring” to you for $9.99, or let you borrow one while you’re in the store.

Hopefully we’ll see Starbucks wireless charging expand to even more parts of the country soon, and the company says it has plans to install Powermat stations in Europe and Asia as well. For now, it’s pretty limited unless you happen to live in SF, though the Powermat website does include a searchable map that will help you find the nearest phone charging station wherever you are.
