Third Genrac Product and still like them.
By from Brownsville, TX, USA on Nov 11, 2015
It may be a bit too soon to give such a good review. I just purchased my GP 3300, I got my Veteran''s discount and 12 months interest free financing, I could not pass on it. Assembly was a breeze, I added the included motor oil and gasoline. The engine fired right up, I ran it unloaded for about 10 minutes, then I plugged in a 500 watt lamp, the generator never flinched. Later in the afternoon, I ran my electric chainsaw, again, no problem, at least not for the first 5 minutes....the engine started surging and died. I had only put in some gas after the initial assembly. I added some more gas, wouldn''t start, I checked everything, all good, EXCEPT, the engine was tilted at a higher level than the power plant, starving for gas. I put in more gas, it ran like a champ. I think I will like my new generator.

Specifications are an outright lie
By from Mobile, AL, USA on Nov 10, 2015
Never mind the double speak on the 14AMP breaker issue. Generac claims this product produces 3300 RUNNING WATTS of power, that is a lie. 3300 Watts = 27.5amps at 120 volts. Anyone who purchased this product based upon their claim of 3300 running watts should demand a refund for false advertising. Simple math folks, look it up.... these people are taking you for fools with their canned response to the complaints of poor performance/lack of power.

Needed a generator quickly for my Camper Trailer
By from Missoula on Oct 22, 2015
Came in box new,opened box,oil leaked from oil jug provided into plastic bag then all over box but still had enough oil to fill generator.Assembled with ease,added oil,added fuel.Went to pull start it and slipped on leaves,surprisingly the half pull I did with me slipping on wet leaves it fired right up,stumbled and stalled,three times later ran perfect.Shut off,fired right back up first pull.Plugged into RV,seems to power electronics with ease however I am skeptical on the wattage output.Ran microwave (1000 watt) it ran but generator bogged down which shouldn''t have occurred with nothing else on in the camper.I hope this power my ac unit when needed or it would be a waste of money for me.Other then this concern all o.k. So far.Was able to lift in and out of my truck bed on my own.

Great product
By from Tennessee, USA on Oct 21, 2015
The generator was very easy to ensemble. Starts up ever time on first pull. Runs all my power tools and machinery with no problem. I would recommend this product for any one in the construction industry.

I don''t have any complaints. Setup was fast and simple. The handle and wheels make it easy to take it places and move around.

Failed after 40 minutes run time
By from NJ on Sep 15, 2015
Gasoline came out of the crankcase, Generac said its my fault for storing gas in the unit? I shut the gas off, IT DOES NOT NEED TO BE DRAINED. Gas ate through the carburetor.

Bought it because it had a 30 amp RV adapter. It will not run the A/C. It provides only 14 amps out of the 30 RV connector. Trips as soon as you turn the A/C on. I was not running any other electrical load. I was mislead by the advertisement.
