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.
