LGMCF Solar Exhaust Fan with 24000mAh Battery Day & Night Work, 25W Solar Powered Fan with Anti-Backflow Valve, Waterproof Ventilation Fan for Shed, Chicken Coop, Greenhouse, Pet House

I bought this for my newly built bike shed after I started noticing mould forming on the roof. I’d already fitted some vents, but they didn’t make much difference. This solar exhaust fan has been a real game changer and has noticeably improved the airflow inside the shed. I honestly didn’t know products like this existed, but it’s turned out to be a great bit of kit. Installation was straightforward, the instructions were easy enough to follow, and it was up and running in no time. The solar panel keeps it working without any extra running costs, and the built-in battery means it continues to help even when the sun isn’t shining. Since fitting it, condensation and dampness have been much less of an issue, and the shed feels far fresher. Overall, I’m really pleased with it and it’s made a genuine difference to my situation. Highly recommended if you’re struggling with ventilation in a shed, greenhouse or similar space.

Screwing this extractor fan onto the side of my garden shed instantly improved the air circulation inside. I mounted the solar panel on the south-facing roof using the included brackets, running the long cable down through a small drilled hole. The fan blades spin up quickly during bright sunlight, pulling the stifling hot air straight out of the building. The internal battery charges up steadily, keeping the fan running quietly well into the late evening. I stood inside the shed during a downpour, observing the external valve flap shut completely tight to stop rain blowing inside. The metal grille on the front prevents wild birds or large insects from entering the blades. Pushing the power button allows me to toggle between different speed settings depending on the temperature outside. It removes the damp, stale smell from my stored equipment without adding a single penny to my electricity bill. The motor produces a low humming sound, bar

This LGMCF solar exhaust fan is a really practical bit of kit if you need better airflow in places like a shed, greenhouse, chicken coop, or pet house without relying on mains power. The built-in battery is one of the best features. A lot of solar fans only really work properly in direct sunlight, but this one can keep running into the evening thanks to the 24000mAh battery, which makes it much more useful day to day. Airflow is decent as well. It helps move warm, stale air out effectively, especially in smaller enclosed spaces where heat can build up quickly during warmer weather. The anti-backflow valve is a good addition too, helping stop air from coming back in when the fan isn’t running. Installation is fairly straightforward if you’re comfortable with basic DIY. Once set up, it’s mostly hassle-free, and not having to deal with wiring or electricity costs is a big advantage. The waterproof build gives a bit of reassurance for outdoor use, and it seems sturdy enough to handle typical weather conditions. It’s not industrial-level heavy duty, but perfectly suitable for home use. Noise levels are reasonable too. You can hear it running, but it’s not overly loud or annoying. If there’s anything worth noting, it’s that performance still depends somewhat on sunlight levels, particularly during dull winter days, though the battery definitely helps compared to standard solar-only fans. Overall, it’s a useful and energy-efficient ventilation solution that works well for smaller outdoor spaces. Great if you want improved airflow without complicated installation or ongoing running costs.

I installed this solar fan in a small shed that gets stuffy during warmer weather, and it’s made a noticeable difference to the airflow inside. The solar panel keeps it running steadily through the day, and the built in battery is useful since it continues working into the evening rather than stopping as soon as the sun goes down. I liked that the fan was fairly quiet while still moving enough air to reduce heat and dampness. The anti backflow design also seems to help keep drafts and rain out when the weather turns. Installation took a bit of planning to get the panel positioned properly for sunlight, but once fitted it has been low maintenance. It probably won’t cool a large space on its own, but for sheds, greenhouses or small animal enclosures it feels like good value and does the job well.

I stuck this LGMCF solar fan on the roof of my rickety six by eight greenhouse after a sticky twelve hour shift, still in my scrubs and craving sleep. A quick drill, two screws, cable clicked into the 25 W panel, done. The clever 180 degree bracket meant I could tilt it away from little Sam’s football line of fire, bonus. By late afternoon the inside temp had dropped from sauna to comfy cuppa territory, and the tomato leaves finally stopped wilting. That chunky 24 000 mAh battery kept the blades turning right through the cloudy Merseyside dusk, I popped out at 10 pm and it was still humming along at a polite 36 dB. Molly the lab never even twitched. And yes, the airflow is punchy, 450 CFM according to the sheet, though I didn’t measure it I could feel a steady breeze on my ankles. But I’d love a longer cable, the supplied lead barely reached the sunniest part of the roof. Almost perfect, just a smidge short.

I’ve been using this solar exhaust fan for a while now, and I’m really happy with how steady it runs. It keeps the air moving even when the sun isn’t out, which makes it much more useful than the usual solar‑only fans. The airflow feels strong and helps clear heat, smells and damp air from small spaces like sheds or greenhouses. The fan feels solid, and the anti‑backflow valve is a nice touch because it stops outside air from pushing back in. The waterproof build also gives me confidence to leave it outside without worrying about rain or steam. Once it’s set up, it just keeps working on its own without needing attention. The battery holds power well, and the fan stays running smoothly through the evening. It’s not loud, and the sound is soft enough that it doesn’t bother me when I’m nearby.

I’m really pleased with this — it’s brilliant for improving airflow in small outdoor spaces. The solar power with battery backup means it works day and night, and it really helps keep areas like sheds or greenhouses cooler and less stuffy. The anti-backflow valve is a nice touch, helping stop air coming back in the wrong way. A practical way to add ventilation without wiring or electricity — great quality and price highly recommended 👌🏻

Umtausch ist kompliziert. Der Akku wurde mit 2 identischen Anschlüssen geliefert. Wenn ein Teil nicht fuktioniert oder wie in meinem Fall schlicht falsch gebaut wurde bleibt nur das komplette Paket zurückschicken. Wer also einen Lüfter braucht der auch gleich betrieben werden muss sollte was anderes kaufen auch wenn die idee gut ist. Der akku ist außerdem Lose im Gehäuse da der minderwertige Klecks heißkleber den recht schweren akku niemals halten kann. Alles in allen gute idee aber schlechte Ausführung. Im Hinblick auf die anderen Rezensionen bezweifel ich aber das der hersteller irgendwie reagiert
