## Description

Solar Exhaust Fan

Review: I put this fan on a chicken coop. I was expecting it to last at least 8 hours after sunset. I am pleasantly surprised that it has ran continuously, the battery has lasted not only 8 hours into the night but a full 2 days on just the battery running non stop. The lowest I've seen the battery pack discharged was 80% The fan is almost whisper quiet. It moves quite a bit of air for my little chicken coop and it had drastically cut down on both the heat and the smell. The solar panel pairs great to the battery pack and 4 inch fan. When the panel is getting light the fan increases in speed and when it runs off the battery it is a little slower. A 4 inch hole saw worked perfect for installing this into the side of the coop. The fan pauses every now and again... maybe it's the solar controller checking for solar input, this is the only minor hiccup over witnessed. As far as quiet, the chickens never even noticed it. This works great in a chicken coop and worth every penny.
Review: Easy to install & it runs like a champ.

### ⭐⭐⭐⭐⭐ Review
*by M***N on 30 July 2025*

4" is working well in small coop. Today is July 30 2025 Eastern USA in a heat wave 98°. Tomorrow is rain. Last night this ran for at least 12 hrs on battery. I forgot to check the power bank status. My problem is lack of solar. So I have to move the panel around to capture sun. I'm still up in air if this is going to stay a permanent fixture. The hardest install was I don't have a 4"hole saw. I managed but that was my biggest pain. Some users are using this backwards tho. This is an "exhaust" fan, not input fan. I will leave it in for the remainder of season into winter but I'm concerned with the draft it may cause during winter. My coop setup may not be conducive for this to run in winter. Very nice product. User needs to address how they will use. That is not company error. It does pull out air and so far has run long on battery and definately stronger on full solar. I will have to see when this rain sets in as to how it handles. Hopefully the solar panel will handle the rain.
