Solar electric calculators and radios work -

There are no reasons to use batteries to operate your calculator in an office, school, or home, when plenty of light from windows or artificial indoor lighting is available.

A solar operated radio is perfect for any time you are camping, boating, hiking, or at the beach, a barbeque, and any outdoor event when the Sun is shinning.

The solar radio shown has a single speaker, don't worry, they also come with two speakers for that great stereo sound!
