The Kinesis K3 power generator gives you another way to obtain sweet gadget juice. In addition to its windmill and solar cells, it can now charge its internal battery with external electricity sources. It doesn’t sound very green, but you can charge its 4,000 mAh battery using a USB adapter or a car cigarette lighter. Why not just leave it by the window to have it fully charged?
According to the company, one hour of sun and wind will give you 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.
