  • ☀️ Powerful Solar Fan for Outdoor Comfort Great for Hot Days!
Size: 18 inches
I’ve been very happy with this solar-powered wall mount fan. It’s a great addition to my patio because I can enjoy a cool breeze without worrying about running an extension cord or using extra electricity. The metal construction feels strong and durable, and the adjustable tilt makes it easy to direct the airflow where I need it. The fan has multiple speeds, and the battery backup is convenient when the sun goes down or the light changes. I also like the thermostat feature because it helps keep the fan running when the temperature rises. It’s quiet, easy to install, and works well. ... show more

  • So far not reliable
Size: 18 inches
I loved this fan so much I bought 2 more. And then ive had issues with tue fan ever since. Day one it turned right on started to work immediately. I I stalled the panels on the shed roof and it worked that first day then the second day the box was not lit up. I thought perhaps the battery died and I needed to move the panels. I messed with this thing for 2 hours in the middle of the day in the heat and got really frustrated gave up and decided I would take it down next morning and return it. Well the next morning I could see the box had lights lit up and low and behold it indeed did turn on. It ran all day although the battery never got above 33% charge it didnt go down either it stayed at 33% all day. I left it on since I left little early and needed the fan to keep working till at least 8pm. It was still running when I got back so I was happy. I stopped the fan thinking if it was not running the battery could charge more the next morning when the sun came up and it was not gonna be as hot the next morning. Once again the box had no power not lit up. Once again I climb up on the roof and move tue panels again and messed with it almost 1 hour it didnt not turn on and the battery box never lit up. So for 2 days it didnt work once again I climb back up start to take the panels down to return the system when I hear the beeb and the box lit up. So I leave the system and it ran all day. We'll that was 2 days ago and im completed fed up with trying to get this thing to turn on, I have no more patience. Since I bought 2 more im gonna try them out and see if its just something with this unit. I want to love this and I did love it that first day but I absolutely have to have something that will actually work. I only need it to run the hottest parts of the day, im considering trying to wire a fan directly to a large panel but that is intimidating, which is why i was so excited about this unit. However I cant keep messing with it every day. So I really hope the other 2 I got will work and its just this one. So im taking this one down tomorrow and update review IF the other fans actually work! Otherwise this will stay at a 1star. ... show more

  • Smart outdoor energy-saving fan
Size: 18 inches
Amazing!!! This solar-powered fan automatically turns on and off, allowing you to enjoy worry-free relaxation while maintaining the perfect outdoor temperature for continuous comfort. Built with a sturdy metal frame, it's durable and features multiple speed settings. The backup battery is especially convenient when sunlight is limited. I particularly appreciate the thermostat function, which helps keep the fan running as temperatures rise. It operates quietly, is easy to install, and performs reliably. I've found that when set to the lowest speed with auto-on/off mode, it works almost perfectly as expected. I'm very satisfied with this solar fan—it saves a significant amount of electricity during summer months. ... show more

  • Excellent Airflow Without Needing an Outlet
Size: 18 inches
This fan has been an excellent addition to our patio. It moves a surprising amount of air, making even hot afternoons much more comfortable. I really appreciate that it's solar-powered, so there's no need to have an electrical outlet nearby or deal with extension cords. The battery stores enough solar energy to keep the fan running efficiently for hours. Despite its powerful airflow, it's impressively quiet, allowing everyone to comfortably carry on conversations while enjoying the breeze. If you're looking for an effective outdoor fan with the convenience of solar power, this one is definitely worth considering. ... show more

  • Not sure why it’s shutting down
Size: 18 inches
I was super impressed with the fan ease of installation etc… but for the past three days the thermostat/controller shut off itself - the battery is fully charged and has been getting sun constantly I’ve checked the wires and connections no visible problem - I’ve only had it set up for 4-5 days but I didn’t know I would have to check it daily to be sure it’s on ... show more

  • Strong airflow and long lasting
Size: 18 inches
Great solar fan. Works very well, has strong air flow, and stays on a long time. The only problem is that it completely shuts down over night and has to be manually turned back on after the battery recharges. It would be better if the fan came back on once recharged.

  • Buyer Beware these are not automatic as implied
Size: 18 inches
I am so angry with this misleading company. I bought three of these. Paid to have them installed in horse sheds. They work great, decent wind, not strong, but pleasant. However, Once they run their cycle they shut off. They will not restart when recharged, regardless of temperature. If you want them to run again, you have to turn them on. They are not automatic. Eco mode is meaningless marketing talk. I paid a handyman to install them with panels on the roofs. I have wasted well over 1000 on this project. Here is explanation from the company: Dear Customer, Thank you for your message. To clarify: once the battery is fully depleted and the fan shuts down, manual restart is required after sufficient charge is restored. The fan will not restart automatically. Regarding your three units: since one controller can manage multiple fans within a 33ft radius, if all three controllers are installed within 33ft of each other, we recommend designating one as the master to control all three fans. Please refer to the attached diagram for master setup instructions. Best regards, ecoCalm Team . ... show more

  • Powerful solar fan!
Size: 18 inches
I bought this to use for my balcony during the day because it faces west and gets extremely hot in the pm. There were a few different ones I could chose from, but this one with its 18” fan and dual panels double sided solar panels work best for my application. I was shocked at how much air this fan puts out. It’s ridiculously powerful even comparing to a plug-in fan. Huge battery pack that allows for this fan to operate well into the evening. I don’t need this at night, instead only during the afternoon when the sun hits the hardest and this fits the bill and perfectly matches my application. I can use this the entire afternoon and still have 75% battery into the evening. I’m so in love with this fan that I would be in the hot sun just to feel its powerful airflow. lol. All in all this is a quality fan at a reasonable price. ... show more
