The GUANGHUI solar backpacks are mobile power generators, designed to charge your devices without tying you to a power outlet, which makes them ideal for traveling and camping.
It combines by four parts: bag + solar cell panel + battery box + adapters Solar bag can recharge most small electronic devices including: cell phones, cameras, PDA's, GPS, PSP games player and MP3s. Note: it is not designed to charge laptops.
the bags come with a set of standard adapters for common cell phones and other devices. We also offer a full range of optional adapters.
Embedded in the outside of the bags are three lightweight, tough, waterproof solar panels which generate up to 2.7 - 4 watts of power. This means quicker charge times!
Included with each bag is a Li Ion battery pack which stores any surplus power generated, so it is available when you need it  not just when the sun is up. The battery pack can also be charged using an AC travel charger or car charger(both included). It means you dont need to bring different adapters again for different electronic devices if you have one solar system in the bag.
