A portable generator is a compact, movable power source that provides electricity when needed. It typically runs on gasoline, propane, or diesel and can power tools, appliances, and lights during outages or outdoor activities. These generators come in various sizes and wattage capacities, making them suitable for different uses, from camping to emergency backup. Many portable generators feature outlets for easy connection to devices and may include safety features like circuit breakers. They are popular among homeowners, contractors, and outdoor enthusiasts for their convenience and reliability, especially in situations where access to electricity is limited or unavailable.
