iZAP Portable Energy battery adds 28 hours of battery life to an iPod Nano

This is one awesome little device. I love my nano but it seems to run out of power too easily. I guess I could bring a charger everywhere but I think just having the long-lasting battery is a more elegant solution. Great for extended outdoor trips. Plus, the device is eco-friendly so I like that too.
