Features 【High Efficiency Output】Micro vertical wind turbines are capable of delivering high efficiency electrical output with power ratings of 0.55 watts, output voltages from 0.01 volts to 5.5 volts, and output currents from 0.01 milliamps to 100 milliamps. 【Light Wind Start】The Small motor blades generator starts and generates power even in light winds, making it ideal for low wind conditions. 【Compact and Portable】Small motor wind blades generator is compact and lightweight, easy to carry and display. 【Adaptable】Vertical motor blade generator is able to adapt to wind from any direction compared to the traditional horizontal wind generator 【Multifunctionality】Micro DC motor can not only be used as a demonstration tool, but also can be used to make scientific models, which has multiple uses. 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.
