Choosing the right generator starts with knowing what you need to power. Small portable generators are useful for camping, tailgating, tools, and basic emergency backup. Larger generators can support refrigerators, sump pumps, furnace blowers, RV air conditioners, and selected home circuits during outages.

The most important numbers are starting watts and running watts. Starting watts help appliances with motors turn on, while running watts show what the generator can power continuously. Always add up your devices before buying.

Fuel type also matters. Gas generators are common and powerful, dual fuel generators run on gasoline or propane, and tri-fuel generators can also use natural gas. Inverter generators are quieter and better for sensitive electronics, while open-frame generators usually offer more power for the money.

Look for the right outlets, electric start, CO shutoff, runtime, noise level, and portability. For home backup, use a transfer switch or interlock installed by a qualified electrician. Always run gas generators outdoors, far from windows, doors, vents, and garages.
