Perfect little bit powerful generator

[This review was collected as part of a promotion.] Such a great and reliable/ durable generator. This one powers our refrigerator and is so handy to have during hurricane season giving us peace of mind in case we loose power.

Love the battery start feature and built-in Charge

We have not had a chance to use the new generator for fortunately, but winter is coming. We feel so sure that we picked the best generator on the market and our very secure in the knowledge that it will take care of us when we need it.

Great Tri fuel generator

I bought this to run my whole house in case of another hurricane and we should lose our electricity. I have natural gas and it works just fine starting my HVAC and all other electric items when hooked to my gas line.

Best in field for reliability.

Bought my Generac generator last Fall but have not had to use it yet as no outage of power so far. Had a stand-by unit before and loved it's reliability but chose this unit with manual transfer system for whole house coverage.

Dependable and easy to use

Bought it for power outages and works great. Just ran it 24 hours continuously with no issues. Easy on gas at low to medium loads. Haven't run it long for big loads.

Work well as expected!

Genarator was purchased last fall to perpared for a possible power outage. Used it for the first time when we lost power for 26 hours after an ice storm. It worked flawlessly to power the well pump, heater and some miscellanenous lights and outlets.
