This could be a nice option for anyone who wants to use the wireless phone charging but does not have a compatible phone or case. Duracell Powermat is selling these "charging rings" to use at some Starbucks stores with wireless charging on the tables. I assume you could get one of these and keep it in the car and just use it as needed and you won't have any wires and if you need to pick up your phone you can. Just a thought.
