Voltaic Systems makes hiking and camping products that produce and store their own power to run your electronics anywhere.  The use of recycled plastic bottles to build the components for their portable solar products makes Voltaic Systems a great company to buy from.  
Voltaic Systems offers recycling programs for old and end of life solar chargers in their “Take Back” program.  Each of their solar backpacks and solar chargers contain valuable components that can be useful for a long period of time. If the components for some reason do fail, they can be recycled to reclaim materials and process hazardous elements safely. If their bags are no longer in use, they would like them back so that they can distribute components to people and groups that find them valuable and make sure any other parts do not end up in landfills. As a thank you, they will send you a coupon worth 20% of your original price plus a free shipping label.
So next time you are wishing you could play Angry Birds at night in your tent at the campsite, but can’t because you did not have a Voltaic Systems backpack on your back as you were hiking on the trail charging your phone or other mobile device, make a note to visit Sheepleg as soon as you get home and order a Voltaic Systems portable solar charger!
