Of course, the electricity generated by a 220V generator can be used to charge electric vehicles with a 220V charger, but it is a bit wasteful because the electrical cost of the generator is very high.
General chargers for electric vehicles are calculated based on 2-3A charging current, but it is around 150W. Your 200W generator is enough to charge, and there is no need to have such a big generator.
Small gasoline and diesel generator: The combustion of gasoline and diesel drives the engine, and the engine drives the generator to generate electricity.
Small wind turbine: The wind drives the blades and transmission parts to drive the generator to produce electricity.
Solar power generation: uses the photovoltaic principle to generate direct current, which is converted to alternating current via an inverter.
Small hydraulic generatorlique: Hydraulic power drives the turbine to drive the generator to produce electricity.
Small thermal power generator: Combustion of biogas turns water into steam, which drives the steam turbine to drive the generator to produce electricity.
