Portable generators are standalone power sources that can be carried or rolled where needed to supply primary or back-up power when electricity is unavailable or insufficient. They burn gasoline, propane gas, or another fuel to generate electrical energy for running equipment during power outages or in remote settings. Inverter generators have an electronic alternator that manages power flow to deliver higher quality power and better fuel efficiency than conventional generators. They also require less maintenance and are lighter and smaller for easier transport and storage.
