Our power was out for four days and my generator failed. I purchased the GP2500i and filled it with oil and gas. It started on the first pull of the cord. I ran it for the next day and a half to power the refrigerator, TV and some lights. It ran for at least 8 hours on a fill up. I never let it run out of gas but I know it was more efficint than my previous generators.

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.

[This review was collected as part of a promotion.] The Generac iQ3800 is a dual-fuel portable inverter generator that can run on either gasoline or propane, offering a 3800-watt starting power (3000-watt running power) and a fully enclosed case for noise reduction. It features an easy-to-use electric start, integrated handle, and never-flat wheels for portability. An intelligent LED display shows power output and fuel consumption, while COsense® technology provides carbon monoxide safety. This will be our best friend for this upcoming hurricane season.

Arrived on time, set up easy and breaking when smooth. I which there was an oil attachment for discharge when changing the oil...As others have stated I agree this price should include a wheel system why pay to another for their adapted kit.?? ME i placed my on a furniture move cart and it work just fine...

First off I won this in a raffle, so there is nothing to complain about. However I would like to point out a few things that I feel could be done better by Generac. First off, there are no break in instructions included with the generator. I assume every small engine needs a break in period so I had to look this up myself and perform it. Secondly, why no wheel kit? Yes it’s kinda light but would a wheel kit be hard to make or sell? Sure would be handy, so I’ll have to make one myself. Third, it was quite difficult to find where to register the warranty. You really have to search to find it.

Due to Covid, I have been living off grid for about a year. I run my generator for 6 hours every 3 days in order to charge my lithium batteries, and it has met all of my expectations. The electric start is great, and I have only used the pull start twice, when it was well below zero. I would definitely buy again. My only concerns are for me, I find the fuel remaining display hard to understand and don't use it. My only other comment is that the spark arrester got supper dirty and clogged up to the point that it made the generator very hard to run. I removed mine and have not had any issues since.

I purchased this to use at an off the grid tiny house and really wanted something quiet. This works perfect for a quiet power source. The only thing I’d like to see addressed is having the oil drain out of the bottom instead of the side. The side drain isn’t very user friendly.

Best generator I have ever purchase, offer me confidence and security that I will never have to buy I generator for a long time, I'm from PR and my family and I don't have electricity since sept 6 2017, due to hurricane Irma and hurricane Maria!! Thanks Generac for so awesome product

Purchased 2 of these portable generators for our RV they are very quite and run great. We like the features on the gas gage and how many hours left till empty are awesome no longer waiting till they run out to see to put in more gas. Takes out the guessing game, also like the feature on how much power your consuming as well.

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.
