Description This vertical wind generator can work no matter from which direction the wind comes. Compared with traditional horizontal wind generator, the vertical generator can work with light wind, but it may generate little less amount of electricity when there is strong wind. Features - Color: Yellow.- Material: ABS.- Size: 7.00X6.00X6.00cm/2.75X2.36X2.36 inch.- Output voltage: 0.01-5.5V.- Output current: 0.01-100mA.- Rated rotate speeds: 100-6000RPM.- Complete product: It needs youself to assemble the wind turbine generator model kits,you can enjoy the fun of DIY.- Mini size:Small and very good for demonstration,can be used as a wind power teaching experiment. Great to cultivate students and kids hands-on ability.- Good teaching tool of wind power generating. Can also be used to make science model.- Low energy consumption: Power generation LED light, low power consumption of LED required, under a fan is enough to get the power to light the LED.- It is just for testing and teaching use ,no actual use . In order to improve the display effect ,the turbine need to be powered by the fan or blow dryer on it at just the right angle instead of the natural wind .Packing list: 1 x motor4 x fan blades
