Backpack Creates Renewable Energy

Unlike my camping buddies who will poke fun at me for this, I will always bring along every electronic device that I can fit in my pack. Gotta have the phone, the camera, and I’ve even been known to sneak a laptop on occasion. Problem is, the batteries are dead within the day and I inevitably regret the extra weight. The Alppac is for anyone like me. It uses a suspended load mechanism to produce an electrical charge when the user is walking. Plug in your phone, iPad, or any other electronic device and get a renewable, clean charge between stops.
