"Always charged on the go."
How often are you in the middle of no where when your cell phone battery dies? How many times have you gone on a trip and forgotten your cell phone charger?
Crave wrote a post about a "Power Purse" which charges your cell phone in the purse. There are several mini solar panels on the outside, so it uses the energy from the sun. The energy is then transferred through USB port to your cell phone. Currently, it's selling for $300.
One main problem I can think of, is what happens if you need a charger at night? Hopefully they have some way of conserving energy for a low battery at night.
Another is that they expect you to keep the cell phone constantly charging. I looked on Battery Charging Information, and they suggest that you don't charge your battery for long periods of time.
