Amazing generator!

[This review was collected as part of a promotion.] This generator is solid. It’s excellent quality, is made by a brand that I trust, and you can tell by the quality of the materials, that this is built to last. I did receive this complementary, however, it has no bearing on my review. I am very pleased with this product, it really is great and well constructed. Grateful for camping and practically any use. I highly recommend it. 5 stars!

This review is for a GP3300i

I haven’t used it very much, just a couple times at home. We bought it for camping with our travel trailer. It is very quiet and responds quickly under load. So far so good. When camping season starts in Michigan we will be using it a lot more. I think it will work great for our application.

Quiet and smooth

Like so many others, we are experiencing fairly frequent outages. Most are quite brief but recently we had one that lasted all day. If it hadn’t been warmer weather we might have had a problem. So.,.. we took the plunge and bought a generator. Since we live on a townhouse and don’t own it, I decided to buy something with enough capacity for the essentials. I also wanted to be able to run as cord to the neighbours to keep them in heat as weIl. It also had to be quiet and reliable. Portability was important. I found everything I wanted in this model. I’m presently making a storage box to keep it outside do I don’t have to carry it up from the basement although it’s doable. I would recommend this product. As a matter of fact, I recommended Generac to my mother and sister in law. They got a larger one since they had the space and wanted something to run more things in the house. Noise level also wasn’t as big a factor for them.

Runs good, good value, but hard to start- found workaround

I bought the GP2500i new a the beginning of December 2021 to provide some backup power if the electricity went out. I wasn't looking for a home backup- just to charge cellphones, led lights, run a single 1500W heater, power the fridge or freezer now and then to keep things from spoiling. From the unit's initial start-up, it took 5+ pulls to get it started. Successive starts were the same. 8-10 pulls to get it to start. Fresh fuel, 90+ Octane, no difference. From other reviewers on other websites, this seems to be a problem with this unit. However, I saw a post from a reviewer on another website with the same problem and he suggested 5-6 slow pulls with the unit set on Run, flip to Choke and then quick tugs to start. I tried his suggestion and it worked- 6 slow pulls followed by 3 actual quick pulls and it started and ran with no problems. I then ran it 20 min with 3/4 load. Stopped it for 5 mins to add fuel and it restarted on Run with 1 pull. This is with 60 day old, 91 octane gas treated for ethanol and storage protection. I would give the unit 5 stars if it started better. Other than that, it's a a great value for the money for the usable wattage it has. I hope this information is helpful.

Nice unit, but difficult to start

I have older version of this unit (G0071171). It was difficult to start when we first got it , but has gotten worse with time. Now, even when unit is sixty degree range it takes 16 pulls of starter rope to start the generator. It has less than twenty five hours running time on it.

Does what's it's designed to do - make power.

I purchased my Generac 3300I generator on 6/20/24 from Menards. I have used it on several occasions - camping, power outages, projects, etc. and now have 79.1 total engine hours (installed an hour meter when purchased). I have had perfect service, no issues whatsoever, and it has powered everything I needed to power. All I have done is to use Seafoam in the fuel, service the air cleaner and change the oil as recommended. I am a happy camper.

Excellent portable generator

After months of extensive research, I chose the Generac IQ3500 as a home back power source. All of the pre-work paid off. This unit is very well built, runs extremely well, and is unbelievably quiet. Could not be more pleased with this generator. Well done Generac.

Bought today Replacement generator

I bought this generator this morning, to replace my generator that was giving me some problems. Its so much quieter than the generator i replaced. It is lighter. It is also very stylish and pleasing to the eyes. The quality is outstanding. It is easy to start. Its also easy to add fluids. I love this generator! Im so excited to have such a quality product. I live off grid 100 percent of the time. I need reliable, dependable, and easy to operate products. Thank you Generac!

Part of My Readiness Plan

As a resident of earthquake country, and a member of our local Community Emergency Response Team (CERT), I needed to complete my preparedness kit by adding a home generator. Unlike other users who have reviewed this model, I am not a camper, I don't regularly need portable power for tools, nor do we have an unreliable power grid. However, I don know what will happen when we have a large earthquake and that power will be unavailable for days, perhaps even weeks, following such an event. As a CERT member, we practice for such situations all the time and I have seen plenty of portable generators in use during these exercises. I'm impressed by the cost/benefit ratio of Generac and trust that the IQ series will be just what I need for my home. I regularly run it as part of its maintenance schedule, place an electrical load on it, and am very satisfied with its performance. As I live in a townhome complex, my neighbors appreciate that it runs quietly.

Quiet, Feature Loaded, Efficient Portable Generator

The Generac Portable 2200i is the quietest running and feature packed portable generator I have ever used. The sturdy built framework with a built-in handle makes portability a task easily accomplished. Whether your need is for home backup or for on-the-road convenience, the Generac 2200i fulfills the requirements. The unit is beautifully colored in orange and black and compels one's pride to surface when showing it to friends or family. As well as doing the normal things a generator does this baby also comes with a 12v DC battery charger to make sure you aren't left stranded because of a dead vehicle battery. This can be real handy camping in the boon-docks. An included feature is a USB charging port for all your small electronic devices, ensuring your wireless communication even where there is no electrical power source available. Never miss a call, text, or email. Even go shopping from a remote area with a fresh charge to your phone, laptop, or ipad. Do all this in the Economy Mode and use less fuel and greater noise reduction. The Generator Status Lights let you know at a glance that power is active, low-oil warning ( and shut down), and overload alerts if you're attempting too much for the unit. In case you need more available watts (power) the Parallel Ready ports connect two inverters together for twice the power. All this is possible by just turning the simple to use Start Dial and cranking up the generator. Sit back and enjoy the evening while the OHV Engine does the rest, while assuring long life of the generator. With a two year Limited Warranty what more could a person want for a price that can't be beat? A very helpful Owner's Manual and Tool Kit is included with each Generac 2200i Portable Generator, making maintaining the generator a task easily accomplished. I highly recommend this excellent generator for your consideration of purchase. It is a winner all the way around!
