Baylis Revolution

The Baylis Revolution is a wind-up MP3 player that features video playback, a photo viewer, an FM radio, a voice recorder, a line input recorder, a text reader, expandable memory, and a flashlight. You can even use it to charge your cell phone.

The Baylis Revolution is bulky and does not support DRM-protected music or video.

The Baylis Revolution may be overkill for recreational camping, but it's a perfect boredom-buster for globe trekkers, outdoorsmen, and fans of green energy.
