The Power to
Live. Work. Play.

Portable generators are a welcome addition to many activities at home, at work, and away. In an emergency, portable generators can provide critical backup power. They make camping and tailgating more comfortable. And contractors appreciate the flexibility portable power brings to the jobsite.

The Power to Live

Many get their first introduction to portable generators when they need emergency power. During a power outage, Generac portable generators make sure the most important items—lights, refrigerators and freezers, sump pumps, even space heaters and window air conditioners—are up and running, minimizing any disruption to your lifestyle.

Portable Generators for Backup Power

The Power to Work

Utility power isn’t always available where and when you need to tackle home improvement projects. Take a Generac portable generator to that far corner of your property instead of running lengthy extension cords. Or rely upon portable power if you need to turn off utility power for extensive home improvement work.

Portable Generators for Work

The Power to Play

Roughing it is only fun until you can’t make a cup of coffee or charge your cell phone. Bring a Generac portable generator to your next tailgate party or camping trip and you’ll have all the comforts of home wherever you are. Power kitchen appliances. Charge personal electronics. Watch TV or listen to music. Generac portable generators ensure the good times roll.

Portable Generators for Recreation

Rated 5 out of 5 by Gunnerg5 from GENERAC IO3500 I purchased this generator a few days ago to use with my travel trailer and it did not disappoint. The A/C unit in my trailer is louder than the generator. I can not hear the generator when the A/C is running. It powers everything in my trailer. Great product.

Rated 5 out of 5 by Roelsroyce from Perfect Size for Portability Thought this was a little pricey for the size but needed something to run a sump pump & a refrigerator in power outages. This is sized perfect for my wife to maneuver in a power outage & I am not available.
