In the summer, those few minutes in the car before the AC kicks in can seem like hours, so keep cool with a Koolatron AutoKool Solar Powered Vent System. This solar powered ventilation system will keep your car cool while it's parked. Simply fit the vent over a clear or lightly-tinted window that sees a lot of sunlight, add the weather stripping and close the window! The solar panels will keep the AutoKool running when your car isn't to keep it cool while reducing air conditioning and fuel consumption.
