I'd need to see fact sheets or read usage reviews before committing, but the idea of the Ray solar-powered charger sounds great. It's these first two photos that really caught my eye, as the idea of being able to juice up your phone by sticking the Ray on an airplane or car window is immensely appealing, inner skeptic aside.
If there's no window handy, or if the sun's position doesn't jive with vertical mounting, there's also an onboard "kickstand" that lets you set the Ray on a flat surface.
As you can see in the shot below, the device needs a bit of industrial design help; I disagree with the word "neatly" being used to describe the cord solution.
But there's time yet for that ID help to materialize, as the Ray is not in production; it's currently under consideration at Quirky, where you can sign on as an influencer. And with your help, it just might "stick" the landing.
