Car Solar Powered Window Exhaust Fan, Air Purifier, Solar Power Air Vent Radiator Fan for Backseat or Frontseat, Vehicle Ventilation Fan (White)

Not effective

Wasting of money. Does not work like they say it would. Car is still hot and you can't feel no air blowing out

I wasnt expecting much, and it only sorta delivered. There is a button to switch from battery to solar powered. It uses 2 AA rechargable nimh batteries, neat idea, but if they are in while on solar, there's not enough power to charge the batteries and run the fans at the same time. Only ran 2 fans at a time, the middle fan was loose and makes an awful racket if on, but that's fine since in full sun it seems only capable of running 2 fans at speed. The window-top seal is a good idea, and works well, but the fan body itself is likely to let water in if it rains.

Haven’t used these yet, but I’ve seen several on utube using them. It’s exactly as described. I love that it runs on its own solar! I’m sure it’ll keep my vehicle cooler in the shade and air moving I bought another smaller one so I can use in two windows. I’m happy with it as it appears to be as described.

Waste of money. Returned the next day.
