Compact in design, the Generac iX800 gas-powered portable inverter generator (model 5791) is designed for life on the road. Its durable, lightweight design with built-in handle offers portable power for camping, tailgating, and recreational use. The iX800 features inverter technology that reduces the size, weight, and noise of the generator and allows for the engine to run at varying speeds, significantly reducing the noise and fuel consumption levels. And its special electronic microprocessor can also provide safe, stable power for sensitive electronic devices such as computers. 
800 watts of clean power to safely power sensitive electronics (see larger image).

Generac finally replaced my leaking unit. Hours of work on my part. The new unit idles quite different. On normal mode it idles significantly lower and flucuates up and down. In the economy mode, it simply idles even lower. The first unit seemed to idle normal (who knows) or high. In economy mode it flucuated up and down as stated in the manual. The electrical outlets are different. The first unit had commercial 120v outlets - one plug vertical, one horizontal. I spent $50 for a commercial extension cord. The new unit has regular (parallel) plugs. Therefore I'll need to buy an adaptor. Unbelievable. If there are any more problems I simply will pay someone who knows what they are doing (Generac's service people do not) or throw the unit out. Stay away from this unit. And stay away from Generac.
June, 2010 - 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 motors". A great excuse. I will contact Amazon corporate office if necessary to tell them not to sell this company's products and file in small claims court if necessary against Generac. Please consider other manufacturers' if you are looking for a small generator. I may be contacted at nfre at comcast dot net for photos of leak. Thank you.not what I had hoped for By Ken H
I bought the generator to use on my boat to occasounally keep the batteries up when camped away from the marina. I was very disappointed in the loud noise level. It is advertised and also marked on the box as "ultra quiet"; well it is as loud as a lawn mower under load, and I wouldn't want to listen to that noise for hours at a time, nor subject that to fellow boaters nearby. I had expected maybe something that wouldn't be a nuissance and may be nearly as quiet as a Honda. No way, this is unacceptable to have to listen to.Real junk, no warranty coverage By Russgary
I bought this generator to use for charging a battery bank on an RV. I never got it to run for even 10 minutes, when I took it to the factory authorized repair depot they said it had water in the gas, they told Me this before working on it? The tank I fill My equipment with is used on 7 engines none of which had problems. The so called repair I had to pay for and accomplisehed nothing, I still cannot use the generator, and the factory refuses to warranty it. I have two other generators a 6 kw and a 1 kw both constant speed type one of which cost 99 dollars and puts this one to shame. Very poor showing and no warranty beware.
