What’s cooler than an iPhone case that recharges your battery? How about an iPhone case that recharges your iPhone’s battery with the sun.

Etón has released the Mobius NSP300B Rechargeable Battery Case for the iPhone 4. Featuring a 1800 mAh rechargeable lithium ion battery, the NSP300B sports a solar pack that will charge your iPhone with the energy it draws from sunlight.

Originally previewed at CES, Etón’s latest creation is definitely unique. The case itself actually looks pretty good. It weighs in at 3.4 ounces and includes a Micro USB cable.

The power pack features a fancy LED indicator that displays the amount of charge that’s been collected on the solar panel. There’s a stand by switch that allows you to collect solar energy without actually drawing from the case’s charge.

Etón claims that its case will give 25 minutes of talk time, 20 minutes of 3G data usage, 35 minutes of video playback, or 145 minutes of audio playback on one hour of solar charge. A fully charged case will provide 5 hours of talk time, 8 hours of 3G data usage and video playback, or 32 hours of audio playback.

You can pick up the Mobius NSP300B for $78 on Amazon.

What do you think of this particular case? Useful? Or do you prefer the darkness?

    Is there any chance that this same case would work for the new iPhone(s) when/if they’re ever actually announced? I love the idea, but I’d hate to drop $80 on a solar case that I’ll get to use for another 3 weeks.

  • Why do they think we want a 12 pound case that is always stuck to the iphone? Even when the iphone is inside on my desk or in my pocket… A solar charger is awesome but not one that doubles as a ‘case’… that just makes it inconvenient.

      Agree 100%. This case is stupid.

  • Mcsteven

    Yeah if the solar panels could detach then that’d be good. Otherwise a stupid idea. How often are you outside on your iPhone anyways?…

  • Tyler Hauser

    I agree with the idea that this is silly as a case AND that releasing a case for a phone that will be a generation old in a few weeks seems dumb, but I see the use for portable power if one hikes or geocaches or that kind of stuff. I like the idea of it as a sort of survival tool in the event of getting stranded or even in the case of a major disaster.

    “Where’s my solar charger for my phone?!”
    “Oh right, it’s already on my phone.”

    It kind of makes sense.

  • not attractive may be people will not recommend to further.

  • nice shipping time lol

  • SimonOrJ

    Looks like great case if you go on camping or some trip without car or any other power…
    Does it work on iPod Touch?

  • Most Solar Panels and use Any light to charge. Anyone know if this one can?

  • Technomancer

    Since my iPhone generally stays in my pocket or is face up on my desk, will the solar charging still work?
