A generator with a 4000-watt capacity is a portable power source capable of operating various household appliances and tools. For instance, it could simultaneously run a refrigerator (700 watts), a microwave (1000 watts), and several lights (100-200 watts each). However, starting watts, which are higher than running watts, must be considered.
Having a reliable power source offers significant advantages, especially during power outages or in locations without access to the electrical grid. This type of generator provides backup power for essential devices, ensuring comfort and safety. Historically, generators have played a crucial role in disaster relief and construction sites, providing electricity where it is otherwise unavailable.
