Novothink has announced that its Solar Surge charging cases for the iPhone and iPod touch are finally available. It will cost you $79.95 for the iPhone 3G/3GS version and $69.95 for the iPod touch version (second gen only). They are each available only in black or white right now, but additional colors are coming soon. We just don’t know when.

It should give you between four and eight hours of talk time, or up to 20 hours of additional audio playback when the charger is fully charged, but the company says you can still expect to get between 30 and 60 minutes of talk time after two hours of exposure to direct sunlight.

Is it worth it? Anything that ups the talk time is good. Let’s hope that they are as advertised.
