In the market for a solar backpack? Consider the new Solar Backpack from Eclipse Solar Gear of Round Rock, Texas: made in the good old U.S. of A., these bags are built to military specifications and look pretty tough (especially in Camo, pictured below).
This bag is constructed of Cordura nylon, and “mil. spec.” webbing, zippers and buckles–so you know it isn’t likely to shred at the first contact with the pavement, say, and will hold up under regular daily use. It also features an integrated thin film solar panel that provides up to 4 watts of power to recharge your mobile devices on the go.
When the sun is shining, the bag charges its internal battery, so when you need more juice for your cell or other mobile device, you can simply hook it up to your bag via a 12V auto adapter or USB, day or night, and recharge.
