Electricity on wheels!

[This review was collected as part of a promotion.] We’ve never had a generator before and now we don’t have to worry about our power going out! This is literally electricity on wheels! It was very easy to set up and fairly quiet when it’s running. It runs on either gas or propane. We will be using it on camping trips or if the electricity goes out. It’s very compact and easy to move around. All in all one powerful generator!

Great buy!

Purchased this generator at the last second while on a camping trip. Noise level was next to nothing....had the unit sitting 10 feet from three of having a conversation and didn't notice it was there. Very simple to start and fuel efficiency was excellent.

IQ3500

I usually never purchase a new product for which I can not find other reviews. I purchased this generator for the portability and the compact size. I am 100% glad I bought this model. Started the first time, ran quieter than I expected. I am considering on purchasing a 2nd unit and hook them up parallel with each other.

*Almost* Perfect

We have a trailer RV, and a 13,500 BTU A/C, so needed the 3,000+ startup power. I've been researching generators off & on for ~6 months and finally pulled the trigger on the Generac GP3000I for the following reasons: - Low weight (60 lbs w/o gas) - Low decibels - High power (able to handle our A/C) - Made in Wisco (where I live) I would give it 5 stars, but unfortunately there isn't a perfect generator out there at this level. Ideally the GP3000I would have the following features: - Fuel shutoff switch (so you can run the carb dry, not sure why this isn't a standard feature!) - Wheels (yes, 60 lbs is a lot lighter than comparable brands with this power output (aka Predator etc @ 100 lbs), but some casters would be nice. Lastly, the instructions could be a little more clear about the oil (they ship you 0.6L that fills capacity so you can put it all in, but that isn't readily clear). Otherwise, very happy with how quiet the unit is, low weight, sharp appearance, and it started up on the 2nd pull.

Generac has great features

Being in my late seventies this unit was recommend by my son in law because it would be lighter and quieter. We do a lot of ice fishing and the dealer also recommends this unit to handle all of our needs. It also has sleek features and handles easily.

Hard to start and you can’t get to the spark plug.

Because it’s kind of an idiot proof user interface. You can’t turn the gas off, so I’m sure it floods itself regularly. If you want to check the spark plug you can’t because the sound insulation is cockeyed to the plug so you can’t get a socket on it I might have to take a knife to it, or just buy a Honda.

Bought two (2) GP3300I

Purchased on Amazon and they arrived in excellent condition. Set-up was very easy and both units started on the third pull with a fresh tank of gas. I am vey pleased with the noise level of these units and they should serve their purpose during a power outage, camping or tailgating. They are an appropriate size and weight for the power output and the price was ~$800 less than the two (2) Honda units with less running wattage. The only "wish list" item would be a larger fuel capacity, but that holds true for all generators in this category.

Outstanding Value

I was shopping for a generator inverter to cover my basic needs in the event of interruptions or failure of our electrical grid locally as well as nationally, especially in the very uncertain times in which we live. I considered the top of the line units all the way down to the extremely basic. Generac covered all the bases for me. Generac has a long history manufacturing time proven dependable generators of nearly every kind.The GP2200i provides the minimums needed to efficiently run all the appliances I require to get by. Best yet for a top notch machine it does all this without breaking the bank. The only item I feel is lacking is perhaps a built in hour meter.

Soooo quiet!

[This review was collected as part of a promotion.] The iQ3800DF generator by Generac exceeded my expectations by a mile! Out of the box, it come practically assembled. All you have to do is add the supplied oil and gas and it is ready to start up. The dual functionality of gas and propane is one of many excellent features. It has a pull start as well as an electric push start button thanks to the supplied internal battery. My favorite part of this generator is the low sound levels. I could not believe how quite this unit is! If you activate to "ECO" mode, it lowers sound levels another (in my estimation) another 25-30%. Maintenance seems to be easy! There is an easily accessible oil drain to make oil changes a breeze. Overall, this a fantastic generator and I highly recommend a Generac to anyone looking for a quality portable genrator!
