Inching closer to an alternatively powered world, Etón Corporation debuted today the Mobius rechargeable battery iPhone 4 case with a solar panel ($80). First previewed at this year's CES event, the battery case with a monocrystal solar panel requires only one hour of time in the sun to get 25 minutes of talk time, 20 minutes of Internet use, 35 minutes of video playback, and over two hours of audio playback.
For tech addicts on the go and often away from any sort of charging option, the convenient part of Mobius is you can choose when to use the extra battery power stored in the solar panel. With a USB connection, you can also charge the old-fashioned way via computer and sync with iTunes at the same time. Let your iPhone bask in some vitamin D.
