HONUTIGE Solar Powered Car Ventilator, Solar Powered Car Exhaust Fan, Car Radiator,Eliminate The Peculiar Smell Inside The Car and Can Be Used for General Types of Cars (Black)

The temperature inside my vehicle gets up to 130s degrees Fahrenheit during the summer. I have a thermometer (that records trends) mounted in the cabin and use sunshades in my windshield and windows. I purchased this device to stop the temperature inside from climbing that high. I hoped that the temperature would at least match the 105 ambient temperature outside. It did not do that. The temperature inside the cabin remains in the 130s. No change what so ever. I installed the fan system Thursday afternoon, and the temperatures continue to trend similarly to those before the device was installed.

To early to tell if product helps keep car cooler but it can't hurt. UPDATE: after several hot summer weeks, I believe the solar fan is helpful but not impressive in lowering the interior temperature of my parked car. It also helps to "crack" a window on the opposite side to help create some air flow direction. I am doing a better job of managing my car's heat this summer than last year. Added rain gutters helped a lot. Nothing beats parking in the shade.

This required DIRECT sunlight on it to run the fans at all. Any overcast and they will not run. Not really worth the money unless you have the skills to install a larger solar cell on the roof or a window and wire them to that.

When you let it on so when the sun comes up, you need to be there to turn it on. I start before the sun is up and wanted it to come on when the sun came up. Doesn't help much when I get back to the truck it is off. And it is daylight and the fans are off.

The item was fairly easy to install. The fan is just not powerful enough to cool any portion of the car.

With three fans, I expected it to move some air, but the exhaust port is so small that it simply back-pressures and makes noise. The switching is confusing and poorly done. There are three on-off switches, each controlling a fan, and a single push button toggle where you can switch the unit to "Off", charging the battery, or operating the fan, but I can't seem operate the fan while charging the battery or use the battery to run the fan. There's apparently some weird pattern of clicking the single toggle to do this, but I can't make sense out of the Chinese instructions that were translated to English by a Russian. Don't waste your time here. Move along.

For it’s size, do as expected.

Works as advertised but the solar panel hinges are VERY fragile. Hint...
