Solar Powered Cell Phone Charger

what do you think of my idea? a solar powered cell phone charger for those on the go?

it would simply plug into the terminal as you would any other charger pack. only this would have a surface area of about 3 by 3 inches. with a 1/2 inch thickness??

They already exist.
