One of the finalists at the 2008 edition of the "Feel the Planet Earth" Cifial Design Contest, the Kuaray Solar Charger and Case by designer Ruben Freire is created to serve as a sustainable and portable charger for portable devices like laptops, tablets and smartphones. The portable charger can be attached to the outer surface of portable devices and can even be stretched out over a glass window to capture and harvest maximum sunlight.

The basic elements in the design of the Kuaray Solar Charger and Case for Portable Electronic Devices are a PowerPlastic PV panel developed by Konarka, an efficient Li-Ion battery and a lightweight aluminum structure that allow the charger to capture maximum sunlight and harness energy from natural light even when the device isn’t directly exposed to the sun. The Kuaray Solar Charger and Case for Portable Electronic Devices is compatible with a range of devices which makes it the ideal portable solar charger for all kinds of gadgets that one may need to keep powered on the go.
What really makes the Kuaray Solar Charger and Case for Portable Electronic Devices different from other similar portable solar chargers in the market is the fact that its design uses non-traditional materials like corn, wasted soda cans and organic particles that makes it more sustainable to manufacture and replace.
