Outstanding Value

I was shopping for a generator inverter to cover my basic needs in the event of interruptions or failure of our electrical grid locally as well as nationally, especially in the very uncertain times in which we live. I considered the top of the line units all the way down to the extremely basic. Generac covered all the bases for me. Generac has a long history manufacturing time proven dependable generators of nearly every kind.The GP2200i provides the minimums needed to efficiently run all the appliances I require to get by. Best yet for a top notch machine it does all this without breaking the bank. The only item I feel is lacking is perhaps a built in hour meter.

Great Inverter/generator

Well it took a week or two after getting my new Generac IQ2000 before I could mess with it. I put the oil in and gassed it up, set evertything to "ON". It took several pulls for it to start the first time but it ran great. I love the "Time Remaining" the gas and also love the load graph, really neat features. It is much quieter that I expected. I think it will be perfect for what I bought it for. Thanks Generac!

Soooo quiet!

[This review was collected as part of a promotion.] The iQ3800DF generator by Generac exceeded my expectations by a mile! Out of the box, it come practically assembled. All you have to do is add the supplied oil and gas and it is ready to start up. The dual functionality of gas and propane is one of many excellent features. It has a pull start as well as an electric push start button thanks to the supplied internal battery. My favorite part of this generator is the low sound levels. I could not believe how quite this unit is! If you activate to "ECO" mode, it lowers sound levels another (in my estimation) another 25-30%. Maintenance seems to be easy! There is an easily accessible oil drain to make oil changes a breeze. Overall, this a fantastic generator and I highly recommend a Generac to anyone looking for a quality portable genrator!

Nice unit, but difficult to start

I have older version of this unit (G0071171). It was difficult to start when we first got it , but has gotten worse with time. Now, even when unit is sixty degree range it takes 16 pulls of starter rope to start the generator. It has less than twenty five hours running time on it.

Not Quite Adequate for RV AC

Despite it saying it will power a single rv ac, NOPE‼️ At least not here in Moab Utah. Keeps throwing a engine code on the control panels. Unit stays running but doesn't generate any power. And it doesn't throw the units breakers. My 30yr old Makita 3500 watt powered it just fine, but, it was much louder and thought the quieter unit would do the trick...WRONG‼️

Bought two (2) GP3300I

Purchased on Amazon and they arrived in excellent condition. Set-up was very easy and both units started on the third pull with a fresh tank of gas. I am vey pleased with the noise level of these units and they should serve their purpose during a power outage, camping or tailgating. They are an appropriate size and weight for the power output and the price was ~$800 less than the two (2) Honda units with less running wattage. The only "wish list" item would be a larger fuel capacity, but that holds true for all generators in this category.

Very pleased

Purchased through Amazon, arrived in a timely manner in perfect condition. Unpacked, added oil and ethanol-free gas, it started on the 2nd pull. Very satisfied with how quiet it is, will be using it with a small travel trailer. Let it run for 20 minutes with a light load, then shut down. A few hours later it started first pull and I connected to the trailer and started the A/C. The generator was only about 2 feet from the trailer and I couldn't hear it inside with the A/C running. Let it run for 30 minutes, then shut it down. So far, so good. Had to buy the adapter plug, no big deal.

Iq3500

At this point I have not used IQ3500 for it intended purpose. Therefore I am unable to fully rate the product at this point However I do have one concern. The lack of servicing dealers and the availability of maintenance kits in my area More to come

Great generator - poor welds on wheel brackets

Opened the box to a brand new one thousand dollar generator. Everything looked great. Not a blemish anywhere. Started assembly and all is well. Wheels installed no problem. Handle, added oil, connected battery, gassed up, started and ran beautiful; again no problem. First time moving on wheels; problem. Both wheel brackets broke free from all but one weld. Impossible to move more than six inches without backside wheel pigeon toeing into the muffler. Hurricane Delta was fast approaching to my area of south Louisiana so I wasn’t about to return a good running generator. I would tough-out the inconvenience and deal with it after the storm. I wasn’t about to return the 200 pound unit and spend the time assembly another. The generator turned into a thousand dollar stand-by insurance policy. I’m otherwise happy for making the purchase. I’m not the first one to experience the weld breaks after reading reviews. Serious consideration for a Generac whole house standby generator purchase is now in jeopardy unless my complete satisfaction with warranty claim is made.

Pretty nice gear for the money

Needed a backup and bug out generator. I’ve had to evacuate twice for hurricanes in 3 years. Had a generator, but fuel was an issue after the storm - hard to get. This model is big enough to run my new fridge (very low power) and even do some basic amenities and to charge a phone and other things. I put in the oil and was pleased at the toolkit and funnel provided. Nice touch. Put in a cup of ethanol free gas (89) treated with Sea Foam and that puppy literally started on one pull. Very smooth and quiet. Tested all the plugs - all good. Took the rest of the pint of oil (supplied) after it ran 10 minutes. Very slick design. The out of oil cutoff is brilliant. It has features really designed to make this a brilliant camping/event solution. Would like to see instructions to purge the carb bowl added to the manual, and the registration site is register.generac.com, not what it says on the manual. I have a great little backup that is quiet enough to take camping or to events. Really a sweet little generator.
