The device also has an LED on the bottom that lights up red while it’s charging and green to indicate when it’s finished. The Solar Window Charger also has built-in measures to prevent overcharging and overheating.
Although currently only available for purchase in silver, promotional images of the Solar Window Charger show the product in green and black as well, indicating that more colors maybe on the way in the future.
The XD Design Solar Window Charger can be viewed and purchased online at a German site called design3000 for EUR49.95 (which is approximately $66), and we heard about it from The Cool Gadgets.
