A backpack that’s also a mobile power generator! This is a backpack with 3 solar panels embedded in the outside. The panels are lightweight and waterproof and they generate up to 4 watts of power. It’s great for charging cell phones, PDAs, GPSs, iPods, cameras etc. so you’re not tied to a power outlet. The bag includes a Li Ion battery pack. This battery pack stores surplus power. As a result, power is available when you need it, not just when the sun is up. In addition, the bag can be charged using a car charge or an AC travel charger, both of which are included. It’s perfect as a large daypack or can be used as a weekend hike bag.
