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.

I purchased two 3000i generators as emergency backup power for my home and my daughter's home. I wanted to run emergency power for two refrigerators, one freezer and outlets in my office for tv, computer, usb charging and minimal led lighting. I hired an electrician to install a sub-panel and inlet for the generator to handle the 4 circuits I wanted to use. I checked the power needs for all the appliances. Since it weighs 60lbs I bought a cart for it and it is very easy to move from the garage to the outdoor sub-panel. All I have to do when the power goes out is to turn off a 50 amp breaker in the main and sub panels, turn on a 30 amp breaker in the sub-panel, plug in the generator and turn on each of the four circuits one at a time to make sure there is no overload. We tested the generator over a period of an hour with all four circuits on. It worked great and surged only slightly when one or more of the appliances cycled. The cost for parts and labor from the electrician was about $1000.00. I strongly recommend a professional installation. You can have serious problems if not installed correctly. It is comforting to know that our families food supply is protected and our communications equipment will function during a blackout. To accomplish all this the generator would only need to run 4 hours a day when the monitors on the appliances show a need to cycle. At a 50% load that is only 1 gallon of fuel per day. Communications equip. would be used in that 4 hour window. I found the build quality excellent. The only change I would make is to make the oil access door bigger and smooth the edges of the opening. It is difficult to get a big hand in and remove the oil fill/check plug. It started first pull and ran very smooth and quiet.

We are the owners of J&G's Place 2B, a bed and breakfast in Ripon, WI. A massive storm hit Ripon and surrounding areas on July 28, 2021 and shortly after midnight we lost power during the middle of EAA Airventure, when Oshkosh hosts the world's largest airshow for a week. This is also the busiest week of the year for our business. A requirement for a bed & breakfast license is that you MUST HAVE HOT WATER, otherwise you are to close immediately. We were looking at a couple of thousand of dollars of lost revenue if we could not stay open. I got out our Generac 3500IO for the first time, a bit worried about making it work. It took all of ten minutes to set up (put in oil and gas and run our extension cords) and it was easy to use (started on the first pull) and kept our business humming and our guests happy for the two days it took the electrical crews to restore service. It already comes with the oil you need for the oil reservoir. Took about half of the included bottle to get it to the right level. It was nice not having to hunt down a bottle of oil. Ran all night and more on one tank of gas, so it is efficient. Especially impressed with how quietly it runs. One thing I would love to see: is there a wheel & handle kit available for this model, and a rain canopy/cover I could buy so it is easier to transport and also be able to use it in the rain? Thank you, Generac, for saving our business. Best, -Jason & Giselle PS: Using two extension cords plugged into the two outlets on the generator, we ran two refrigerators, a chest freezer, a natural gas hot water heater, two lamps, and 2 CPAP units, and had some Watts to spare, plus we charged phones and tablets through the 2 USB ports on the back of the generator. We buy the most energy efficient appliances available, which means we were able to get by with a much smaller and less expensive portable generator that will fit in the back seat of a Toyota Corolla when it is boxed up, which perfectly describes the 3500IO. We recommend it highly!

Seems like a great product but the motor started surging after the first hour of usage. I suppose there is a plugged orfice of some sort in the carburetor but I don’t really want to take it off and clean it. The fuel filter should have taken care of this issue. ??

I bought this generator to run my cab-over camper on various trips throughout the year. I had a 2K watt previously and it just wasn't enough to handle the microwave and other accessories, so I upgraded to the Generac 3K watt and at first was impressed at how quiet it was and how it seemed to handle all my accessories fairly easy ripening through the 30amp RV outlet, but then...on a recent trip I decided to camp in a tent shelter and use the generator to run a 1500 watt space heater to keep warm at night, but unfortunately it was not able to run the heater without going into fault mode. So I went to town and bought a second heater and had the same issue. I tried powering it through the 30 amp outlet with an adapter and had the same problem. Unfortunately I have no idea how a 3K watt generator can't handle a 1500 watt space heater, but this generac cannot unfortunately. Pretty disappointing to say the least. I run non-ethinol fuel and make sure the oil level is good, so I'm just not sure if the governor is set too low so it can't reach a true 3000 watts or what the issue is? Back to the drawing board I guess. Would I recommend this generator now? Probably not. At first, absolutely.

I bought this to power a small rv with a small a/c unit. It is strong enough to handle it; however, I am having to purchase an adapter to go from the L5 outlet to the TT30r. $800 is a lot to me, but this is my third generac product and all have worked well. It is quiet. I just wish that I had known that it would not work out of the box without purchasing something else. I called customer support and told them what I needed and they did not inform me of that either. Not a negative review but a head's up for future buyers.

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.

I choose it for my Rv. I took it on an12,000 mile Alaskan trip which included frost heave and dirt roads. The only issue is it quit cranking off the electric start. It does crank easy off the pull start. I had to use the pull start most of the trip. It was new when I left. It’s super quiet! If others are running around I couldn’t hear mine at all even though theirs were a good distance away. Generac meads to sell it with a cover or sell a fitted cover. I had a problem with dust getting in the receptacles as a couple are for electronics charging.

I usually never purchase a new product for which I can not find other reviews. I purchased this generator for the portability and the compact size. I am 100% glad I bought this model. Started the first time, ran quieter than I expected. I am considering on purchasing a 2nd unit and hook them up parallel with each other.

[This review was collected as part of a promotion.] The build is solid, everything looks professional and well thought out. Started up from the first time! What I was particularly pleased with is that it is very quiet, especially compared to other models. It doesn't rattle, doesn't scare the neighbors, doesn't disturb my sleep. You can safely turn on at night. The power is enough for the refrigerator, and for lighting, and for charging appliances at the same time. Works both on gasoline and propane - convenient when one of the options runs out. The digital panel is simple and straightforward, you can see everything: how many watts are being used, how much time is left - a complete sense of control. And yes, its weight (122 pounds) can be felt, but on wheels it rolls easily like a suitcase, not dragging with effort. In general Generac iQ3800 is peace of mind in any situation: blackout, going out with family, working remotely - it will not let you down. Beautiful, powerful, smart - I recommend it 100%. Yes, the Generac iQ3800 DF generator does support both gasoline and liquefied propane operation. This is confirmed by the model's official specifications - Dual Fuel: Runs on gasoline or liquid propane, providing flexibility in the choice of energy source.  - Run time: up to 13 hours on gasoline and up to 16 hours on a 20-pound propane tank at 50% load.  - Power: 3,000 watts in run mode and up to 3,800 watts when running on gasoline; 2,700 watts in run mode and up to 3,400 watts when running on propane.
