The Logitech Wireless Solar Keyboard 750 is an efficient solar-powered keyboard that uses light sources -- both natural light from the sun and electrically produced light from lamps and fixtures -- as its power source. This wireless keyboard doesn't require batteries or external cords, depending only on light sources for power.

This solar keyboard doesn't need to constantly be in the light in order to be able to function. In fact, when it is fully juiced up, it can hold enough charge to run for three months in total darkness.

Users can ascertain their keyboard's battery power or figure out how much power they're getting from their light source by using the accompanying Logitech Solar App.
