Can a 12-volt generator be converted into wind power generator?

Yes. According to the speed it can provide, the generator should be modified so that it can provide at least 12V or 6V electricity at this low speed. Regardless of power, this is completely achievable. Vehicles can only generate electricity when there is wind. The first is when driving, and the second is when there is strong wind. Using wind power to generate electricity while driving not only increases the driving resistance of the car, but also wastes fuel consumption. It is far inferior to using the car directly. It is more inconvenient to use a generator to generate electricity. The second type is driven by strong wind to generate electricity.
