Solar Briefcase

Everyone packs their clothes whenever they go for a holiday, but the next time you decide to head for a beachside retreat, why not bring the Solar Briefcase along with you? Inside you will find a pair of solar panels capable of churning out 13 watts of power under direct sunlight – that’s enough juice to charge up a cell phone within an hour. Sounds like the perfect holiday device, but an extra piece of luggage isn’t exactly the most convenient thing to carry around if you want to travel light.
