Customer Questions & Answers

It went dead and won't crank back up what should I do.

Asked by: DW
Check the oil level, sounds like the low oil shutoff engaged.

Is there a list of appliance, tools etcetera this will run?

Asked by: ray
Yes, Google it under Appliance Wattage Usage, and it comes right up. The most wattage, is used by heating and cooling appliances. Lights, tv, fans, computers, etc, don't use much wattage. During Katrina, I was able to power a few lights, 32" tv, fan, and pc computer, with a similar, less quality generator from Harbor Freight, so the IX800 Generac should do better

Would this be capable of running a pitching machine for 1 hour

Asked by: Lurch8
Depends on the power requirement of the pitching machine. If it is a standard 15amp machine then you shouldn't have any problems.

I am new to the world of generators; what can I run with my generac ix 800; I know it won't run a pot of coffee

Asked by: Anonymous
Yes, GL.. it actually WILL run a pot of coffee.. and then some. Unless you are trying to power commercial 1000 Watt unit which requires a 220 outlet anyway. C'mon, get with the program.

800-Watt Gasoline Powered Portable Generator is rated 3.5 out of 5 by 19.
Rated 2 out of 5 by from Works but not great ECO mode barely changes anything on my new one, my old one just like this worked better for about 3 weeks then it stopped making electric all together so i exchanged it. Although it was replaced with the same type of generator they run different the old one ran smooth the new vibrates heavily while on either mode loaded or not. I would not recommend this generator and will be returning this one to get my money back.

Rated 5 out of 5 by from great little generator i have used Generac generators for years where i work. 4000 watt gens. They worked great for years of service. So i knew Generac made good,larger generators.Smaller,compact ones are just as good.Have used it camping,ice fishing a few times this winter.Powered my camper lights,small tv and inverter with noooo problem.

Rated 4 out of 5 by from Good little unit This is all the power I needed to keep my camper batteries charged. It's a little loud when not running in eco mode, tolerable though. Fuel seems to last forever in eco.

Rated 2 out of 5 by from I had to fix a brand new generator Picked it up at the HD in perfect condition. We opened the box in the parking lot to check for damage. A very strong odor of gasoline came out of the box. I thought the item might be used but not the case it was new. I pulled the spark plug to check condition. The plug is OK but the gap is incorrect. I set the gap to .030. Added oil and started up after 3 pulls. The voltage output is good @ 122.4 -122.7 volts. The engine is not running correctly, it is surging without a load. let run for awhile still surging. Shut down and let cool. Pulled the air box off and sprayed carb with Gumout carb cleaner, closed choke and let it soak for 20 minutes. Sprayed more carb cleaner and closed choke. put the airbox back on. Restarted and after a few minutes it ran nice. Voltage remained the same. Operated TV (220w) for about an hour no static, very clean power. Ran a string trimmer (500w) on Econ, RPM takes a dive and then recovers to operate the trimmer with plenty of Power. After 4 hrs I changed the oil. I notice plastic shavings in side the supplied funnel. How sad, they shipped it from China with gas in the Carb. How hard is it to gap the plug correctly. What else is screwed up. Definitely no QC. I am holding my breath because we need this to run our pellet stove during the winter.

Rated 1 out of 5 by from Worst purchase ever! I finally had it with this generator. Tossed it it trash. Would not start easy. In ECO mode it would quit. Worthless
Date published: 2015-06-25
Rated 1 out of 5 by from Started Up, Then Quit After unpacking, I went to fill it up with oil. The oil cap is recessed and very difficult to reach. Even my wife's smaller fingers had great difficulty reaching the oil reservoir cap. You are filling oil in the blind and must stop frequently to see if the reservoir is full. The spark plug looks equally difficult to change. The starter rope is hard to pull, and I have seen much larger generators require less strength pulling the starter cord. If you have to drain the oil, the owner's manual instructs you to purchase pvc tubing that fits the oil reservoir opening, then tilt the generator. Draining the gas would be another great problem with reaching the drain plug. Generator started up finally, ran less than ten minutes, showed an overload (nothing was connected), sputtered and died. I could not restart it. I am very disappointed and do not recommend this unit. At least I had no problem returning it to a local Home Depot.

Rated 2 out of 5 by from limited use Fired this generator up at home and ran a tank of fuel through it.It ran fine.Took it up north (where it was to be used )and couldn't keep it running.If it won't run at 6,000 or higher,it is of little use to me.

Rated 5 out of 5 by from Excellent portable generator! 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!
