Next time you're outside listening to tunes and catching some rays, put the sun to work! The Eton Soulra powered speaker system for your iPod or iPhone uses sunlight to recharge its built-in battery. The flip-up solar panel captures light in clear and cloudy conditions, so you can keep the music flowing.
And great for indoor use, too
The stereo full-range speakers can push out the sound when you're outside, but they have a nice 'inside voice," too. A small remote lets you control the system from across the room. The AC power cord keeps your Soulra charged until you're ready for your next outdoor excursion be it the beach or just your backyard.
From the review Fun in the Sun with the Etón Soulra Solar-Powered iPod Speaker System
""When I'm outside, I need a system that can produce a big sound, and the Soulra delivers. Its stereo full-range speakers don't produce audiophile sound, but they do provide the punch necessary for an outside setting. The Soulra was a great little no-frills system to take along on vacation especially to the beach, or out on the lake, by the pool, or other places where moisture might be an issue."
