"Shortly after purchasing my iPhone I thought about I could turn my iPhone green. That is is when I found the Hymini. I absolutely love this little device, it is a portable battery with a mini wind turbine. When I attach the Hymini to my bike I get free power and when I am done biking, I simply hook up three solar panels (the device supports up to four). And when the sun sets, I have the hand crank to keep the power flowing! This little thing has kept my iphone completely grid-free." - John Stevens
