Did not work waste of money

. Have no idea what the extra electronic diodes are for. Requested a refund.. you must pay for return shipping and print a return label. Save your money.. a complete sham! Also was quite difficult to assemble because pieces and holes did not fit well.

It’s pretty much a prop toy. Can’t get it to produce 12v, so don’t think that’s what you’re getting.
Other than that, it’s ok. The generator housing is 3D printed and the blades feel almost like PVC. You’d be better off making one if you’re looking for functionality.

VAWT which is what this is, as a technology does not have a good track record. you can research this at NREL website. The dialog for a selling point is to use this as a decoration, or for class tells you a lot about the product.
one comment was about the parts and in the video you notice that what is being done is to build an electrical one-way gate. as the power flows from the turbine, the 3 phase power has to be directed to flow one direction. by building the diode rectifier bridge, which is what the long fingernail is pointing out.
if you were to hook this strait up to a battery it could be an issue. that is why you need a charge controller. even for a small game feeder battery, i would think a strait hookup would be disastrous.
i am going to buy one to play with and will post a long, detailed review and try to present some real data such as start up wind speed, and voltage/amp (watts) that will help.
for those of you that want to understand the truth of wind power, the HAWT models have a history of longer service life but do require maintenance which includes the house hold 20 year guarantee models. VAWT types suffer from vibration which increases at the blade size does. m/s = 2.23 mph. to know the power of the wind, use the cube of the speed, and wind turbines (and towers and other things) are designed to withstand the cubed wind speed in a 3 second wind gust. so an 8 mph wind is 8 times weaker in mechanical force that a 16 mph wind although the wind speed is only 2 times stronger.
i hope this helps and i will post a review as soon as i do some testing.

It’s specification were accurate and it’s price is low enough and better yet the design is simple enough that I’ve not been afraid to experiment with it or experiment with modifications to it.
So far I’ve mounted it on a 46 oz juice can and using set screws to make it easy to move it around the farm placing it on several wooden post of various heights and locations.
It was clear in the specifications it takes a significant amount of wind to get any useful charging out of it, but the ?PVC? blades that come with it are a simple enough design I feel confident that it will be easy to make longer versions out of local PVC water pipe that should let it work with slower wind speeds.
One warning the design is obviously focused on hitting the cheaper shipping range so it has several lightweight parts, not that I blame the designers for designing it this close given current shipping cost they managed to keep the shipping cost down to reasonable range for something where size and weight make a big difference.
if you plan on modify the design with say larger blades as I plan to it would also be a good idea to strengthen the central support in some way.
All told the roughly $50 I paid was well worth it to find out the problems and gotchas of this type of wind generator before buying or building a larger more expensive version.
