An MP3 Player That Doesn’t Need Batteries
We’ve reported on these environmental friendly MP3 players before. Here is another one. The Cranking MP3 Player that doesn’t need batteries. “To get power on this strange device, you just need to make use of your hands, and start the cranking sessions. One minute of cranking, results in 10 minutes of power, which means that after 1 hour of continuously cranking, there will be 10 hours of non-stop music.” And you don’t have to worry, you can also use an AC Adapter, or a USB port to charge the unit.
