Understanding Portable Generators

A portable generator is a mobile power source that converts fuel into electricity, making it an essential tool for outdoor events, job sites, and emergency backup power. They vary widely in size, power output, and features. Some models are designed specifically for sensitive electronics, offering clean inverter power, while others provide heavy-duty power for construction tools and industrial equipment.

Fuel options usually include gasoline, diesel, or propane, and many generators are equipped with multiple power outlets to support several devices simultaneously. When selecting a portable generator, it’s important to consider:

• Power output (running and starting watts)

• Fuel tank capacity and run time

• Portability features like wheels and handles

• Safety features such as CO sensors and low oil shutoff

• Noise level and suitability for sensitive electronics
