Why: Sure, you go to the beach to relax and get away from your techno-driven daily life, but the occasion will inevitably arise where you'll need to break out an electronic gadget. Whether you're texting your friend the location of your towel and cooler or you want to snag a secret snapshot of the hottie down the way, you want to make sure your electronics can last as long at the beach as you do.
Enter the Juice Bag, a beach tote with built-in solar panels that harness the sun's energy and use it to juice up your toys. Each roomy duck canvas tote has a car lighter adapter socket tucked into it. Just plug the same adapter that works with your car's cigarette lighter (you can score the cord you need at Target for $15) into your MP3 player, camera, cell phone or GPS and you've got a charge in a couple of full sunlight hours. The portable power to keep the juice flowing will cost you—the bag's $250—but you can remove the panels and adapter socket for easy washing or to use elsewhere.
