DIW: Greenlighting Solar Power Bank

WICHITA, Kan. You've probably been there before: your phone's about to die and there aren't any outlets around.

The makers of the Greenlighting Solar Power Bank say as long as you've got sunlight, you've got a way to charge your devices.

The Greenlighting Solar Power Bank is a mobile device charger that promises to use the sun's power to keep your devices going. Its makers say it comes with a convenient suction cup mount.

Does it work?

To find out, we got some help from Susie Bruffett with the NIAR Environmental Test Lab.
