I also have a Honda Eu-1000i and am able to compare the two. This unit costs a lot less, is equally light and well built, comparable to the Honda in quality. I connected a hour meter/tachometer to mine and it started easily. But....its noisey. It idles at 5400 rpm and revs to 6000 rpm during load. the honda putters quietly at 4000 rpm under light loads like charging gadgets or running an electric blanket in the tent. This thing screams and is LOUD. After 1 hour we were tired of the drone... and couldn't put a long enough cord on it got get rid of the racket... so back to walmart it goes. Sorry Generac. try again. This little guy has great potential if they'd slow the idle down during light loads. BTW, it would not operate a tiny 4700 btu window A/C. The honda EU-1000i will start and run the same A/C unit and still stay at quiet idle for hours. Hope this helps.

We are sorry to learn of your dissatisfaction with our iX800 portable inverter generator. Please know that model number 5791, is capable of providing 800 AC rated output running watts and 6.6 amps at 120V; a product capable of providing 25% more wattage, such as the one that you have used for comparison, should be able to power greater loads. If you are interested in a portable inverter generator that runs at a quieter sound output level with higher power output ratings, we would recommend anticipating the release of our new iQ2000 portable inverter generator. If you would like to learn more about this particular product, please contact us directly at 888-GENERAC (436-3722).

I purchased this little unit "solely" for camping lights and it does this perfectly. Understand that it's only 800 watts, if you want to run a refrigerator and all the camping items you want to bring, "DON"T buy this unit, it's too small. This is a fantastic unit for a fan in the tent and a light or two. I haul this unit on my ATV and it's light and very portable. It has already ran over 4+ hours with lights on and not so much as a hick-up. I broke the unit in slow and changed the oil as the manual says and have even gave it a second oil change in 10 hours time. If you want to compare this unit to others that are three times the price, don't bother… For $300+ dollars it is a "VERY NICE" unit for the money. Take care of it, follow the instructions and it will serve you well. Only thing is I use a 50ft extension cord to get it away from the camping area, it is slightly louder than some other small units, "but" for the money and a long cord, "no problem"!

The generator was very easy to use and did everything i needed, but I should have went with the higher wattage generator. I didn't realize how much power some of the appliances took. Overall its a great buy if you just need it for smaller appliances.

I did a lot of research to find a generator that was properly sized to my system and would not use a lot of gas. This seemed to have decent quality and reasonable features. When I opened the box (shipped by UPS) the plastic bag that covered the generator had oil in it, the supplied quart bottle of oil was not breached and did not leak. I opened the side cover and the entire inside of the unit was covered with a thin film of sticky oil, amazing that it could disperse itself around in there so thoroughly. Oil was half covered the outside of the unit and was running down the front plate and out of the receptacles, clearly it had gotten into all of the circuitry. I called the manufacturer technical support and they said they do not ship with much if any oil in them. So the unit I received must have been tried by someone and returned? Luckily the Walmart local store returned this generator no questions asked (oil and gas removed, but I never started it). I did add oil to it before I decided to return it and it did not seem to leak, maybe the leak was in the filler plug? I have since read that people do have trouble with these leaking oil sometimes at the engine case joints. I would have bought another one like this from Walmart at the time of return but the price had gone up $20. And I realized that I just keep hoping for a different kind of world where quality is not something that requires a mortgage to afford. This unit is as much plastic as it can use, like most things these days and it was clear to me upon close inspection that it is not really meant to last more than say 10 years without a major breakage because plastic will not last. So I guess I am going to get a more traditional style generator, I think the Powermate 1200 might do the trick and appears to have a similar fuel usage rating. So this unit would be good for tailgating if someone has extra money to spend on it but it is not really, in my opinion, going to be a super reliable item. I would say it is not the worst quality, probably mid grade but nowadays that means you never know when it will fail. The Honda version that costs about 3 times as much is more of what I would probably want but no way I am paying that much, too much responsibility. Oh my, will we ever have a World with quality in everything we do?

by Some juice is better than no juice

Since I don't have any experience with other brands/models, I'm not sure how useful my review will be, nevertheless: Set up was actually a breeze. I REALLY did read the instruction manual (and I am a MALE!) once as an overview and then for detail as I went through the set up process. It is basically add the oil, add the gasoline, turn 2 knobs, pull the start rope. The machine started right up on first pull. Highly unusual for any small, gasoline-powered engine. Loaded with two lamps and then a paper shredder so as to assess the "power-up" function and it worked just fine. I thought I saw a flicker one time in the lights when I fed the shredder, but could have been the other lights in the home. By the way, I only used one outlet of the two available -- if that makes any difference -- I had a 15 ga 50ft ext cord and at the end of that had a heavy duty 3 way outlet. As I write, I am listening to the engine run as I allow it to run out of fuel for storage. It does seem to chage RPM quite a bit without a change in load. This makes me wonder a bit about the carburation. For what it's worth, that is my review. If you just want an inexpensive back-up for low load use, this will serve you well.

I bought this as a demo unit from Brand New Engines.It essantially is a brand new reconditioned generator. I put in the oil, and seafoam treated premium gas, primed the IX800, one pull and it started. Put a 750 watt load on the gen - and it revved up and powered the lights without problem. The gen does change RPM up and down - this is how an inverter is supposed to work. I have owned at least 5 generators - Kohler, Honda, Tecumseh powered craftsman and a China Honad clone.This works as well, weighs much less and does what it is supposed to do. It's quiet enough. Is it super -duper quiet? No but is is quieter that my 4 ton AC unit. Remember though - this is a gas engine powered item and will have fuel issues if you let old gas sit in it. Seafoam has never let me down!

All The Stuff I Wanted To Know. Bought through Walmart and it was delivered promptly. Have had a number of inverter generators so I was familiar with them. Hondas, Kipor, and a cheapy two strokes. There have been a lot of new lower cost units on the market in the past few years from companys getting into the market trying to pick the right one is tough. Some of them are junk right out of the box and getting them fixed or returned is a big factor. Not a great fan of Walmart but at least I can take it to the counter and say "this does not work, money back please" Needed something small enough to get in a suitcase to bring to Central America and have enough juice to run small things like lights, small hand tools, etc. It came shipped without oil or fuel but it had been tested at the factory so had to leave the gas cap off for a week to get rid of all the test gas fumes. TSA will toss the luggage immediately if there are any gas fumes when they open the bag when leaving the US and they WILL open the bag when they see the generator on the xray. It passed TSA inspection in the suitcase. It weighs 30 lbs so a smaller strong suitcase will work best. Took a chance on this one by power, size and weight. I was not disappointed. Started immediately and ran perfectly. Downloaded all the operating instructions for all the candidates and found this one had a small stroke of engineering genius which was a small pressure pump on the gas cap to pressurize the fuel system for a few seconds to get fuel to the carburetor. Works excellent and saves the pull recoil mechanism from the repeated 15-20 pulls to get started from a dry carburetor after even a little storage time and with US ethanol gas even worse. Are you listening Honda, Yamaha? Came with a great little perfectly fitting funnel for changing the oil which you wont want to loose. Oil change at the first 5 hours is a must, it gets pretty nasty. I have about 50 hours runtime on it without any issues. Sips gas, fairly quiet, and will carry a load well. Big thing: It will not start an inductive load anywhere its maximum rating which means electric motors like drills, pumps, small saws have to be started without load and when up to speed then apply load. Example is a sump pump rated at 625 watts had to be started dry and when up to speed dropped in the water or it would stall the motor. Does not have a big start load capacity. Forget the eco mode when starting motors. Other than that the thing worked great. My first choice would have been a 1000 watt Honda or Yamaha but I had to see if I could get it through TSA and a Central American country Customs without loosing it somewhere in the process. A $1000 loss would have been tougher to swallow than a $300. I was not disappointed in the machine. Ran it dry of gas, sealed it up and i will see what happens in 6 months when I go Back.

Was a skeptic but once i fired it up at the Bama game it was as quiet as the higher priced Hondas. I reccomend you try this one out before you spend the extra dough on the name espeially when you get the same quality and value for the need. I would reccomend this to all can't wait for the power to go out so I can watch the TV and not have to listen to the roar of the generator I ha before I purchased the Generac brand. This unit is lightweight and user friendly just turn the gas on and plug the cord(s) in and you are ready for a quiet and peaceful tailgate at your favorite teams campus.
