Add A Solar Panel To The Back Of Your Phone For Extra Charge

If there's one thing most smartphones have in common, it's awful battery life. DIYER Paulie gave his phone a bit more juice by installing a solar panel on the back.

To put this together, you'll need to solder the solar panel's connections to a USB cord, then plug that into your phone. Paulie also cut open the back of his phone and attached the solar cells to the back panel (though we imagine it'd still work if you put a case over it and installed the cells inside that). You can the solar panels from two cheap landscaping lights, and they can put out about 3V each, which together should be enough to get some extra charge into the phone. It's a perfect little hack for if, say, you're out at the park, eating lunch outside, or otherwise under the sun and want to give your phone a little jolt. Check out the video above to see how it's done.

    Hmmm,... now all you need is to strap it to your head any time you're out side.. :}

    Ugly but cool :)

    My phone is always in my pocket. My wife thinks the sun shines out of my you-know-what, but I think my phone feels differently...

    What a waste of a phone,You can buy solar powered cases in a million different shapes & sizes on ebay for cheap as.
    Having the panels attached to the phone means it's required to be in the sun & i see two glaringly obvious problems...
    1: As shane said, your phone is in your pocket 99% of the time.
    2: Iphones dont like heat,once they get hot enough they display a warning then they shut down till cool,And it doesn't take much sun exposure to get to this level.I've done it a few times 8)

    IMO more people need SGS2's, since the batterylife is so superior to everything else :P
