This is for the tech savvy nerd in all of us.  How funky, yet practical, are these bags?

Here (above) we have the Voltaic Solar Backpack; it has 4.5 watts of solar power, a battery pack to store power until you need it, 10 different adapters to charge nearly all your electronic gadgets, and wire channels throughout the backpack for headphones, plugs and cords.  The solar panels are made of a high efficiency monocrystalline cell that is waterproof, UV resistant, and scratch resistant.  It is able to charge cell phones, PDAs, GPSs, iPods, cameras and other hand-held devices in about 4-6 hours of direct sunlight.  This backpack will run you $249 at Voltaic Systems or Amazon.com.

The Eclipse Fusion Solar Messenger Bag (above) has nice look and plenty of good storage.  Great for charging your cellphone or PDA while you wait for the bus or reading the newspaper.  We found it for 49.95

Say you want to charge something larger like your laptop?  Bring out the big boy.  Voltaic Generator (above) is the first solar bag powerful enough to charge a standard-sized laptop in a comfy and securely padded laptop bag.  Its solar panels generate up to 15 watts in about 5 hours.  This one will run you about $489.

Not only do these packs charge your electronics with the sun, the bags themselves are made out of 600D fabric which is recycled PET (soda bottles).  They’re water resistant, light weight and durable.  Grab one, and never run out of batteries on your travels.
