Now here is a bag that doesnt just carry all your mobile electronic stuff but also charges them. The bags produced by voltaic systems are fitted with solar panels which would then convert the sunlight to put out electric charge up to 4 watts. Each bag is also installed with a Li Ion Battery pack which stores excess power generated, so that power is still available even when you're not under the sun. The bag could recharge most small electronic devices including: cell phones, cameras, two way radios, PDA's, and MP3s. But it is not designed to charge laptops.
