Generators in the Power Supply category are devices that convert mechanical energy into electrical energy, providing power when access to the electrical grid is unavailable or insufficient. They are crucial for a wide range of applications, including emergency power supply during outages, power provision in remote areas, and supplemental energy during peak demand periods. Generators come in various sizes and types, such as portable units for small-scale needs and large industrial generators for heavy-duty applications. They typically operate on fuels like gasoline, diesel, natural gas, or propane, and are essential in ensuring continuous operation and reliability across sectors like healthcare, construction, and events, where uninterrupted power is critical.
