Q: I'm looking at the Generac iX800 but concerned that it won't run my blow dryer (dog shows) Metro Air Force Commander Vari-speed. The blower says it is 4 horse power, & takes 11.5 amps & 900 watts. We'll only run the blower for about 5 minutes at a time for maybe a total of 1 hr. during the morning of a show. We want it to be small, inexpensive, & light weight to carry to the outside grooming spot. Will the Generac work or what do you recommend? Thanks.
by Gail Kingrey from Colorado on July 15, 2012

A: This model will in fact not work for you. You will need to look towards a unit off approximately twice the size. Being that this unit only powers 800 watts, you will not have enough power to even start the dryer. If you seek a small dependable unit, you might look towards the iX1600 or the iX2000. Both would be suitable to meet your needs.

Q: Does this generac 5791 model has 220 voltage outlet? Tnx
by Angelito from California on March 09, 2012

A: None of the inverter generators we offer have 240V output unless you look at the Yamaha EF6300iSDE or the Honda EU6500iSAC models.
by Mike, Product Expert

Q: Do it run quiet I need something that I can take out to a park and it runs very quiet. I just want to no is it noise free.
by Linda from Florida on October 02, 2011

A: Unfortunately, not all generator manufacturers provide their noise levels. Generac does not provide the noise level on this model.

If you are looking for the most quiet Honda has been known to be the most quiet. The Honda EU1000i is rated at 59dBA which is similar to the sound of normal speech.

Q: I was watching how to take care and maintain of generators and I'm confused when he said you can't wash it down with a hose. My concern than is... it's out in the rain...I just went through a flood and I have a 1/2 and 1/4 horsepower sump pump...just want to hook them up.
by Tina Kepp from Pennsylvania on September 24, 2011

A: No portable generators are designed for use in the rain as they are not water tight and electricity and water do not mix well together. If use in the rain is required then a roof must be placed over the unit to protect it while keeping 3 sides exposed for proper air cooling of the unit.

by Mike, Product Expert

Q: Can the generac ix2000 be hooked together with another ix2000 to increase to 4000 watts? There other models like Honda and Kipor that can be.
by Ken Kercher from Wyoming on January 23, 2011

A: The Generac inverter generators cannot be paralleled together. There is no connection on the unit to do this.
by Mike, Product Expert

Q: What is the noise level of the Generac IX2000? Why don't they list this info in the owners manual?
by Fletcher Pastore from Virginia on January 23, 2011

A: Thank you for your inquiry. Unfortunately, Generac, like many other generator manufacturers, do not publish the decibel ratings for their generators. This unit does come equipped with a Low Tone Muffler and the internal components are enclosed for Quiet Operation but I do not have a decibel number to give you. Currently, there are no industry standards or requirements for generator manufacturers to follow when testing their generators for noise. Due to this, manufacturers can test the noise level under any conditions they choose and, therefore, the results are not very reliable as each company will test under conditions that are favorable to their products.

Electric Generators Direct Recommended

The Generac iX800 is ideal for camping and other recreational events.

This generator may not be as quiet as the Honda or Yamaha but will give you enough power to charge a laptop and run a few lights.

If your looking for an inexpensive inverter generator that can run a few small items then this is a good recommendation.

Generac Ix800 Review
My Generac iX800 sucks but I guess you get what you pay for. Its not as it was advertised, it is very loud and it vibrates so bad that it dances across the floor and the rpm surges up and down regardless whether there is a load or no load. I just get the runaround from Generac and cannot find any dealers in Portland that can repair it or return it for warranty, I will probably just sell it on Craigs List at a loss and get a Honda and tell everyone to stay away from these pieces of crap.

Defected Generator
I was very excited about the new generator. However, when we experience the recent snow storm in Connecticut the generator only worked for two days. I was panic and think that I bought a defective generator. I contacted the company through email no-one ever contacted me. I feel that I have been given a product that did not work up to its potential. What can you do to help me? I am disappointed. If another storm comes I will not have a generator. Disappointed Customer!

Generator
I selected & purchased the Generac ix800 because of 1)price, 2)size, 3)weight, and Generac's reputation. However, I am somewhat disappointed with it. Upon opening the box, I discovered a side plate cracked for no apparent reason (took 2 months to get the part from the dealer). When I filled it up with gas, I found it to be extremely difficult as about half full gas will overflow on the generator (takes forever to fill it and not spill gas). I added oil, tightened the oil plug, pumped the... more

90% Of The Honda, For 40% Of The Price
I have a lot of experience with the Honda EU1000i, owned by a previous employer. When it was time for me to buy I didn't want to spend $800 for the Honda and thought I would give this Generac a try. Overall I am pleased with the Generac, I've put about 40 hours on it so far. It starts and runs as well as the Honda, it's very similar in size and weight, and it's nearly as quiet. I think it is 90% equivalent to the Honda, for 40% of the price.

These are the issues that make up the 10%... more

Generac 800
Do your self a big favor........Save your money and buy a Honda. My generac 800 did not even last a day. The circuit board fried and the dealer gave me a 1600 and I paid the difference. Well there was no difference in the quality in this one either, lasted a whopping 2.5 hrs before it broke. Going to take it back to the dealer Monday AM and then buy a Honda. I knew the price was to good to be true.

Leaked Out Of Box
Unit was defective out of box. Significant oil leak from engine even when not running. Took to 2 authorized Generac service shops. Still leaks. Leak is where 2 aluminum machine surfaces come together. Still trying to get resolution. Generac customer service fair at best. Takes considerable time to reach a human being. The unit already looks 2 years old due to the handling by the repair people and I've never used it. Generac has still not offered to replace. They "don't make the... more
