Here is what you need to know before buying it. The info is based on my testing of the 'Smart wind' turbine by Makemu (Italy). It does actually generate some tens of volts easily, once I even managed to spin it so quickly that my multimeter registered 101.5 V on the MAX setting. Before that I got normal 12 V by rotating the shaft slowly with my fingers, and was kinda pleasantly surprised. However, don't get too excited about the high voltage yet, because there is one BIG CATCH - the supplied M10 three-phase alternator (motor-generator) which presumably is capable of producing 100W of power (max rating I suppose), appeared shy to produce more than 0.185 A (i.e. only 185 miliampers!), irrespective of how fast the shaft is rotated. In fact, I got 150-170 mA again easily at virtually any rate of rotation, but to reach the max registered 185.5 mA I had to work hard (as hard as for 101.5 V)... My further tests with the shaft driven by a drill/screwdriver up to extreme RPMs confirmed my above measurements, especially concerning the current < 190 mA. The moral is, this wind-turbine only looks powerful by the kinda "impressive" voltage figures but is very much powerless in all actuality, because electrical power (Watts) and, for that reason, energy (Watt-hours) is measured as the product of Volts and Ampers (in this case miliampers), i.e. in this case maximum we get is something like 100V*0.2A = 20 W, and this is *at best*. - Well, having my educational background in physics, I have all the reasons to doubt that it can produce max voltage at max current; the physics (electromagnetism and induction laws) simply won't allow this to happen - for a practical test, one can easily check that it's much more difficult to rotate the generator's shaft under any appreciable load demanding current (i.e. not just a voltmeter). Overall, I conclude that this wind-turbine must have been produced as a toy, may-be good for educational purposes (although considering its size I would doubt its usefulness even for that). It is a shame that the manufacturer advertises it as a proper "green energy" solution, claiming that this micro-turbine starts producing "power" in low wind. It only produces mostly useless voltage in any wind conditions, and it's only usable, perhaps, for occasional LED applications (in strong enough winds), where current must be well controlled and kept low. Forget about charging any serious battery or its contributing to a solar-battery array! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07KD68LKX | | Batteries Required? | No | | Batteries included? | No | | Customer Reviews | 4.6 4.6 out of 5 stars (7) | | Date First Available | 22 Nov. 2018 | | Item Package Quantity | 1 | | Item Weight | 998 g | | Item model number | M10_100 | | Manufacturer | MAKEMU' Srl | | Part number | M10_100 | | Product Dimensions | 9 x 8 x 8 cm; 997.9 g | | Wattage | 10 watts | ## Images ![Three-phase alternator Brushless Permanent Magnet Generator Electric Wind Turbine hydroelectric Dinamo 12V 24V 48V - Image 1](https://m.media-amazon.com/images/I/71-+3sCUEXL.jpg) ![Three-phase alternator Brushless Permanent Magnet Generator Electric Wind Turbine hydroelectric Dinamo 12V 24V 48V - Image 2](https://m.media-amazon.com/images/I/91EkUyceo+L.jpg) ![Three-phase alternator Brushless Permanent Magnet Generator Electric Wind Turbine hydroelectric Dinamo 12V 24V 48V - Image 3](https://m.media-amazon.com/images/I/419cWxfuobL.jpg) ![Three-phase alternator Brushless Permanent Magnet Generator Electric Wind Turbine hydroelectric Dinamo 12V 24V 48V - Image 4](https://m.media-amazon.com/images/I/91wdn2n+RNL.jpg) ![Three-phase alternator Brushless Permanent Magnet Generator Electric Wind Turbine hydroelectric Dinamo 12V 24V 48V - Image 5](https://m.media-amazon.com/images/I/91PKZKXKkkL.jpg) ## Questions & Answers **Q: How does it handle the elements? Is it somewhat water protected or would I need to build an enclosure to protect it. Thanks** A: If you look close you will see the sticker on it states 10 watts. I couldn't even get that. It basically produces static not power worthless. I purchased over 50 and have tried to return them all. **Q: so how many dc amps and volts does this put out i dont need watts?** A: It’s 37 V **Q: The picture of the unit says max 36 volt??? Also is this bidirectional or multi-directional?** A: The max is 48 volts. The alternator produces 3-phase or AC power so it will produce the same output in either direction. It comes with a rectifier if you want to cahange the output to DC vvolts. Over all, it is solid built. **Q: What's the shaft diameter size?** A: Shaft Diameter is 9/16" ## Customer Reviews ### ⭐⭐⭐⭐⭐ Well made and easy to use *by A***R on 16 July 2019* Well made and easy to use ### ⭐ This AC alternator cannot produce more than 185 mA, so totally powerless. *by A***B on 1 December 2019* It is the same AC generator that is sold with the so-called 'Smart wind' turbine kit (by the same seller).
