1/2 Pull First Start - Incredibly Quiet

We finally purchase a Generac GP3000i for our RV and household emergency power needs. It is undoubtedly the easiest, most convenient and quietest generator on the market today. I am highly recommending this to any one who is considering purchasing a generator

Great product

I tossed around the ideal of getting a portable generator so I wouldn't have to lug around my other larger ones. I was convinced that the Honda eu2000 was the best and quietest on the market until I started reading about the Generac iq2000 and watching some videos. I just couldn't make myself spend 900.00+ for a Honda. So I purchased the Generac iq2000 last week. It arrived extremely well packaged, with manual, engine oil and funnel. Added the engine oil and some gasoline and it fired right up. This unit is quiet !!! performs well and I love the features it has. Well done Generac !!!

Not impressed

First weekend out with it... first use it wouldn't run write and it spent 2 1/2 weeks waiting on the warranty guy to get approval to work on it and see what the issue was. Just got it back hoping it works this weekend otherwise it's going back to the shop

Great product with poor quality control.

Unit arrived in what appeared to be good condition. Followed instructions to the letter to prep and start. Generator never made any attempt to fire/start. After researching Service/repair supplier(lost two weeks of potential use), then took unit to repair shop (another 10 day delay), only to find that the fuel line was installled with a crimp in it, therefore no gas was reaching carburetor thus it would have never started. Repair was under warrantee, thank goodness. So after a month from arrival, I now have it back(yesterday) and hope to get to try out use. Size, features ( outlets(110 and USB, quietness, and form, fit, function) seem very good. Just need time to exercise use/utility. Disappointing start and significant effort for me to handle, transport, and get repaired but hopefully now in a position to get the utility I needed without more unnecessary delay. General, please review your quality control procedures so this does not happen to some other poor, unsuspecting soul!

Darned Outages

We have been subject to power outages about once a month for hours on end-which pushed me to make power of my own. Here in the South in summertime it gets very humid and without air I have a hard time breathing-well no more. Fired right up on 2nd pull of the recoil and ran as it should right from the start. I installed a wall kit to transfer power indoors without exhaust and rain coming in from an extension cord thru the door. This unit will run a 12000BTU air/heat unit and also other electrical items at the same time without barely a complaint. If I had to rebuy I definitely would.

Some Quality Control Problems

I bought item during a major ice storm in OKLAHOMA CITY in 2020. When I filled it with fuel, I followed the directions and I could not get it to start. I then noticed it was spilling fuel all over my deck. Opening the covers I found that the drain line to the carburetor had been left open at the factory. The local GENERAC dealer refused to even listen since they only worked with hard installed GENERAC units. Furthermore the power out of this unit, isn't clean enough to run the ac motor my furnace. And there's no other way to reach GENERAC other than posting here.

Generac GP2200i Portable Generator

Decided to buy this generator in Aug, 2020 with using it for camping in mind, but due to COVID 19 have postponed camping. In November, 2020 we had a major ice storm in Edmond, OK and were without power for 5 1/2 days. This little generator was a real life saver. It helped us power several items at different times, i.e. refrigerator, coffee maker and television and allowed us to charge our phones, laptops, etc. It is amazing how God plants a thought into your mind and you act on it and everything works out as it should. Thanks, Generac for an excellent product. It started immediately and ran like a champ for the full 5 1/2 days. We will probably get another one for 2021 camping season.

Sucks

I bought one of these generators for a backup for my Ryobi generator and it’s so frustrating!!!!!! It takes forever to get the thing started vs my 10+ year old Ryobi to start. I can start my old Ryobi with 3-5 pulls and it has well over 100 hours on it as it’s over 10 years old! But my generac is much harder to get started and it’s got maybe 10 hours of use on it! I wish I had bought 2 of the Ryobi generators at the same time!!! You say you’re one of the best out there but even Coleman is easier to get started than generacs! I would give it a lower rating but once you finally get it running it does its job. I don’t think I will ever buy another one again unless it’s the cheapest option in a pinch. Good job generic!!

Excellent portable generator

After months of extensive research, I chose the Generac IQ3500 as a home back power source. All of the pre-work paid off. This unit is very well built, runs extremely well, and is unbelievably quiet. Could not be more pleased with this generator. Well done Generac.
