Sounds a bit weird and anti-green, but for some reason now you can charge its 4,000 mAh battery using a USB adapter or a car cigarette lighter. Why would you like to do a single charge with an external power source when you can just leave it by the window to have it fully charged is beyond me.

According to the company, one hour of sun and wind will provide you with 30 minutes of talk time in a cellphone. Fully charged, the K3 can load the battery cells for an average mobile phone five times, or an MP3 player more than ten times.

At $100 it is a bit on the expensive, but if their specs are correct, it looks pretty useful for emergencies. [CNET]

Apparently, one hour of exposure to wind or sunlight will net you around 30 minutes on the phone. A full charge should be able to power up a typical cellphone five times over (LED lights indicate charge levels). There is even a handy clip to attach the charger to a bike or ATV to help generate wind. Obviously, this would be a seriously handy device for outdoorsy types or as an emergency backup. A release date had not been made available, but the Kinesis K2 is expected to retail for $100. [Kinesis and DVICE]
