​Starbucks is experimenting with a similar service in the US, however there it's using Duracell Powermat's PMA technology, a less popular standard, to coax coffee fiends inside. Qi, meanwhile, is reasonably prevalent with a growing number of compatible smartphones, like the Nexus 6 and Lumia 930. Of course, not everyone has a handset with these capabilities, so Aircharge will also be offering its wireless charging receivers for those that need a microUSB or Lightning cable. So now, while you take a quick pit-stop and devour a McRib (for the next four weeks, anyway), your gadgets can be recharging their batteries too.
