The French's modern rules
In most cases, the bag incorporates a solar panel in the front of the bag that continuously soaks up natural light and feeds it into an internal storage battery to create an ongoing renewable source that can used to charge your gadgets. It is a glorified and convenient solar charger.
heavy duty racking The initial concept was born a few years ago but now, thanks to advances in technology, solar components have now reduced considerably in price and raised the bar considerably in terms of quality.
steel pallet A number of solar bags and backpacks have launched onto the market but only a few can deliver the power required to run a serious gadget like an iPhone, Blackberry or Nintendo DS. The concept is still relatively new so only a few on the market are styled in a sophisticated way. Others are still quite geeky looking.

bevel gear Offers backpacks that are not only larger in size but also carry a bigger battery, which leads us to the next feature of battery capacity.A larger capacity battery usually carries a pricier tag like the Voltaic backpacks.

The cells are supposed to last 25 years and should also "self-heal" in the sun. They are very durable and can take alot of "heat" (pun intended), and Voltaic says the bag will continue to function even if one of the panels is destroyed, though naturally, at a lower efficiency.RJY
