If you though a regular solar dock for your iPhone was awesome, prepare to be blown away with Eton�s Soulra XL Solar Dock. The larger, retractable solar panel will help to make sure your iPhone and iPod will charge up for as long as you�d like. This newer model they�ve put out will also be able to soak up the sun a lot more effectively.
For only having to spend $300 on this once and never having to pay for electricity or batteries for it, I�d say it�s quite the steal. The panel is 72 sq inches, which translates to 5 hours of continuous play before the dock would need another sunshine-filled charge. It has an output of 22W, so it�s perfect for any picnic, cabin, or backyard. These won�t start shipping out for a few days, but you can preorder on Eton�s website.
