The Auto Cool Fan uses solar power to ventilate your car when parked on a hot summers day. This is totally awesome. It doesn't need batteries and fits easily into any car window. The solar power harnessed from the sun in this Auto Cool Fan allows it to constantly blow hot air out of the car.
It keeps cars up to 30 degrees f cooler. So if you're sick and tired of super hot days grab a Auto Cool Solar Powered Car Fan .
(BTW if you're into solar power also check out this solar powered light for the garden.)
