In less than an hour!
By from Marietta, GA, USA on May 08, 2016
I bought the Generator at Lowe''s and in less than hour it was being put to the test on the job site. The Lowe''s associate made the purchase and selection easy. The Generator out performed all expectations of the contractor I delivered it to. He was able to plug his hammer drill into the Generator and bore into the concrete slab without hesitation. Have used it several times since that first day. It''s now the go-to Generator for the remodel in progress.

Poor quality, don''t buy
By from Ware Shoals, SC on Apr 25, 2016
Run! Don''t buy Generac! That would be a good starting point. I expected better support and quality from Generac. The first generator I purchased was defective. I assembled the unit and added oil only to find that the case of the motor was leaking oil. After frustration in finding a local service provider to repair the generator, Lowe''s sent the generator for repair. Without adding too much info about my frustration as well as headache in getting the generator repaired, I ended up with a new generator. I assembled the new one and went to start it up and noticed the hour meter was already at nearly 2800 hrs. REALLY! Never again will I buy Generac products.

Deceptive Capacity
By from Pa on Apr 21, 2016
While it is true that the unit can deliver 3300 watts, it can only do so at 240V. If you intend to use it for 120V loads only, you are limited to half that - about 1680 watts. The 14A breaker was necessary to protect the generator from excessive 240V loads, but penalizes the capacity on the 120V side at the same time. It would have been nice if it had a transfer switch and two different size breakers (14A for the 240V side and 25A for the 120V side). At a minimum, Generac should advertise this as a 3300W/240V, 1700W/120V genset. If you need 3000+ watts and intend to use only 120V loads - look for another generator.

Do not purchase
By from Greensburg, PA 15601, USA on Apr 21, 2016
For anyone wanting to buy this generator, I highly recommend you do your homework! It is rated as a 3300 watt generator w/ a 30 Amp plug for an RV. Here is the problem, it has a 14 amp breaker on all the outlets! This means that it is truly only rated at about 1680 watts of safe use. I called their customer support and the girl who answered had no clue how to figure watts to amps and didn''t even know they sold this model, it is a Lowes exclusive. After doing some checking and calling me back (which I was surprised she did) she told me that just because the unit comes with 20 amp plugs and a 30 amp adapter for RV use that doesn''t mean that''s what generator can provide???? Why do they even sell the unit with these plugs if you can''t use them, she could not answer that. I HIGHLY RECOMMEND NOT BUYING THIS UNIT. ****On a side not, Lowes was GREAT about letting me return the unit and get another one. I had the receipt but not the box. ***

Manufacturer''s defect; broken within 90 days
By from Bowdoinham, ME, USA on Mar 31, 2016
We were VERY dependent on our new generator, having just moved to Maine and forced to live in an RV without electricity until we found a home. This model actually broke apart within 90 days of purchase, but we were denied a refund or exchange at this store. We had to take it to a repair shop, where they determined it was a manufacturer''s defect and they fixed it at no charge. WHILE it was being repaired, though, we had to purchase a replacement generator, since it took 3 1/2 weeks. We bought our replacement generator at HOME DEPOT. And we did NOT get a Generac.

Know your max single device draw before purchase.
By from Cedar Park, TX on Feb 21, 2016
This generator will deliver 3300 watts continuous, but note that this must be split between two 14A circuit breakers. in other words, no single device can draw more than 1650W. Homes typically have 20A circuit breakers and so can handle higher loads. The two 120V outlets on the left are one circuit, and the two on the right are the other. The combined watt draw on each set of two outlets cannot exceed 1650W. Also note that the RV adapter which is included can only draw power from one circuit (since the two circuits are out of phase) and so you cannot deliver 3300W of power to your RV through this adapter, only half. If you wish to utilize the power in the other circuit, you will need to harvest it using a standard 120V extension cord. My unit is wired such that the RV adapter draws from the right most set of 120V outlets. In general I am happy with this generator, but if I lived in an area with higher power outage risk I think I would get one with higher capacity. This one should be able to power the blower in my gas furnace as well as a fridge and a few other small loads without hogging too much fuel. My next project is to make an enclosure to silence the beast. It is quite loud. Hope this helps.

With blizzard warnings and loosing power frequently I decided to buy this generator. I got it home assembled ot according to the instructions and tried to start it. After several tries I realized gas was dripping from the carberator, I shut off the fuel valve and it stopped, when re-opened it started dripping again. Needless to say this is going back!!!!!

Priced Right
By from Raleigh, NC, USA on Jan 15, 2016
Was easy to assemble parts. Instructions easy to follow. Previous generator I had was hard to start. Once this one was assembled, I put gas in the tank and it started on the first pull. Very impressed.
