Solar power iPhone skins are getting more popular for everyone. Apple devices with solar powered chargers are already available in the market, but solar powered skins are not. These skins are capable of charging an iPhone or iPod using solar energy. According to Heimbuch from TreeHugger, one of the solar power skins is capable for providing 30 minutes talk time on a 2G network with 2 hours of solar energy charging. Also these skins are shipped with a solar planner application which helps estimating the needed solar charge time during the day in order to have a working phone in the evevning.
Solar powered chargers can provide few minutes of talk time, however with high consumer demand, these devices may gain wider popularity leading to more competition and better quality overall.
