We purchased this fan for our chicken coop as we thought it would be perfect. What we learned is that there is not an option for a back up battery. If there is no sun or it’s an overcast day the fans will not turn on. With the heat in the coop at night we needed them to run 24/7. I reached out to customer service with an inquiry and I was very impressed with their quick response and options for our needs. I do appreciate this company and their team and will continue to order from them.

The sun hit the panel and the fans hummed away.

The fan works great, I just wished I would have gotten a larger one. It’s really hot in the summer and i could use a larger fan.

Bought it to add ventilation for my second home, particulary when windows need to bekept shut. i.e. to boost airflow through vents on window frame. As in use noticed thet it nees real sun to work, on a vloudy day they hadly move. As full sun is available they get going with full speed and noice over 60db. Mayby not so relexing?

Works but fans are not very strong. Using for chickens & they dont seem to like it as much as the box fan lol. We may just use it as backup exhaust fan somewhere else. Was hoping for better fan power than a gentle breeze

Can describe in one word- JUNK !!!! Wasn’t my money !!!!! Please send return instructions

This fan worked for only 4 days and I have been trying to get a return or refund from Vevor for weeks. They just keep sending me the same email back that I have replied to over and over again.

If I could give zero I would. Unusable. The solar panel and and the fan end had two different connection. They could never be used together. They sent me the wrong pieces. There was no way to fix it. No way to make it work. I posted picture after picture of the problem and customer service did not or would not understand the problem. And refused to make it right. All they had to do was either give me a refund or send the right pieces. They kept threatening to close the case and make me stuck with a broken item that couldn't be fixed. I'm now in the same position with another product that they sent that was missing pieces. Dealing with customer service is a nightmare.

installed in a 20 ft shipping container to help cool it down in the summer heat. It worked good for a few weeks but now it has quit. Will work halfway for a while if unplugged from the solar panel and then reattached. Panel will only show around 14 volts unplugged in the sun. I'm betting that is not enough as my other panels show 18 plus volts.

I am disappointed to report this hasn’t worked well. At first it worked great but the battery depleted the first day and it hasn’t recharged since then despite moving the panel to be completely certain it’s receiving full sun. When it operated, it was weaker than anticipated but it did help remove the stuffy feeling inside. The control box is simple yet mildly confusing to use. I have reached out multiple times for help hoping maybe I just got a bad solar panel. The first time I got no response. The 2nd request I was able to chat with someone who I guess just submitted a ticket on my behalf (again?). It’s been a couple days and still no response. I wouldn’t recommend or purchase again.
