DIY Teaching Model Kit Micro Wind Generator Turbine Power with Bulb

Specificationworking principle:The wind blows the paddle on the generator shaft to rotate, when a certain speed is reached, the motor starts to generate electricity, and the higher the speed, the greater the power generation voltage. It generally needs the wind force of the hair dryer to drive the higher voltage and the natural wind can not be brought up.Micro generator1. When the wind is strong, the motor voltage does not carry LED lights and other loads, and the no-load voltage can reach about 20V.2. The motor with USB socket can be directly plugged into the supporting USB light for use. Other low-power USB devices are not guaranteed to be driven. As for charging mobile phones and charging treasures, it will not work because they do not have a voltage regulator module.3. If it is equipped with a regulated 5V module, the charging current is about 3OMA under the peak wind power of the household fan. If the smartphone battery is powered off at 4000MA, the theoretical charging time is 6 days. There are no products of more than 100 yuan on the market. It is almost impossible to charge mobile phones and charging treasures normally. Even if it seems that the current can be charged, it is meaningless.Length: 18cmInner hole: 2 mm (fastening)Material: ABS plasticWeight: About 4.8 gramsInstallation: Positive and negative paddles, which can be fixed on the motor shaft with a shaft diameter of 2 mmUsageIt can light up when running against the wind, or it can be installed on the bicycle to emit light while ridingIt comes with a USB light bulb with a USB cable of 1 m and 5 watts, which can be directly plugged into the power bank and it will light up for emergency lighting at any time.
