Have you used this Solar Powered Cooling Fan? We have tested it and found that this item does not really helps in reducing heat in your car due to slow fan speed. You might needs many set of it to run effectively. Besides that, the fan will rotate only when it receives high amount of sun light. Which is in a very hot day. You need to put it every time you leave the car. If you leave it on your window while driving, the hissing sound from outside air entering your car cabin will annoys you. However, you can try this if you want. It costs only around RM40.
AUTO COOLING FAN SOLAR POWERED
Some description of the product:
The solar powered car ventilation is the original solar-powered ventilator that silently and efficiently helps rid your vehicle of hot, stale and stuffy air, even on scorching summer days! While your windows remain securely closed, the solar powered car vent eliminates hot air and odors from your vehicle and replaces it with fresh air from the outside, ultimately reducing the interior temperature of the vehicle. Auto Air Ventilation exchanges the air inside your vehicle approximately every 20 minutes.
Since the Auto Air Ventilation runs directly on natural, FREE solar energy, there is no drain on your vehicle’s battery and no batteries to replace or recharge. Installation is easy! Simply attach the included weather proof fitting strips to the Auto Air Ventilation, place the Auto Air Ventilation on top of the window edge and roll the window closed – that’s it!
The Auto Air Ventilation helps preserve and protect your vehicle’s interior, valuable stereo and electronic equipment from the damaging effects of extreme heat build-up. Auto Air Ventilation also assists in reducing the strain on your air conditioning system during start-up.

What this product will/won’t do: This is not an air conditioner, it is a ventilation system, and it will reduce the interior temperature of your vehicle, but not cool it (like an air conditioner would). The system will not work with cars whose windows are dark tinted, nor will it work well on cloudy days.
