VEVOR 500W Wind Turbine Generator, 12V Adjustable 3-Blade Wind Power Generator with MPPT Controller, Suitable for Home, Farm, RVs, Boats

2.5m/s start speed is 5.6 MPH. After spending twice the cost of the turbine on the pole and wiring and many hours installing... had solid winds of 10+ MPH with gusts over 20 and it never spun. As others have noted the blade design is poor, the ends are very thin and all but flat. Maybe the 5 blade would start easier? The unit seems solid (I'm a fan of Vevor products and own several), just doesn't work. Don't buy.

Not a big fan of this product. Did not produce any form of power. Even with 15-20 mile an hour wind with gust of 30-40, it didn’t produce. Waited til weather was worse to write a review to se if it would produce power but does not. F-

Its what it says it is correct on the watts and style I find it interesting how no one seems to operate wind turbines correctly if you do not hook this thing up correctly it doesn't spin right it doesn't produce the correct wattage but when wired appropriately and used the correct way this thing is amazing for the price that it is

installed wind turbine, product discription said 4 to 7 mph wind to produce power. turbine wont spin unless 15 to 20 mph. and thats not enough to produce any watts or amps to charge. bad product. wont buy again .
