The Surge uses a solar panel to collect sunlight, which it turns into electricity.If your iPhone is not fully charged, it transfers the charge to your iPhone. When your iPhone is fully charged (or when it is not inserted), the Surge transfers the charge to its internal battery. The charge from this reserve battery will transfer to your iPhone's battery as necessary.

myFootprint also carries the Surge charger for the iPod Touch. THE SURGE FOR iPHONE CHARGER WILL NOT WORK WITH A iPOD TOUCH.
