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 n...

Not great

Would Not Recommend

I bought it in January 15. I have only been able to start it twice. Neither time when I wanted to use it. I have another one of these that has worked fine for several years. This one is at a warranty repair shop and has been there over a month now.

Quiet yet powerful!!

[This review was collected as part of a promotion.] We originally didn't plan on opening up this generator until our Memorial Day camping trip next weekend but a downed tree on our power lines at home this passed week changed that plan! We were without power for just one day but with the help of our flashlights on our phones, my husband and I were able to put it together. The Generac iq3800 Dual Fuel portable generator comes fully assembled but we had to make sure the battery was connected, add ...

Great new iQ model to the lineup!

Would Recommend

Great new product from Generac. We also have their other iQunit, iQ3500, which we use for camping and other needs but needed something with more functionality and ability to connect to our LP tank which this product solves our need. Super quiet, easy to start and move around with the added wheels vs the prior model.

Ready When We Need It!!

[This review was collected as part of a promotion.] I was lucky enough to receive the Generac Dual Fuel Portable Generator as a gift from Influenster for review, and while we haven’t needed to put it to the test yet (thankfully, no power outages!), I can already tell this is a game-changer for our home. From the moment it arrived, I was impressed. The generator feels incredibly well-built — solid, durable, and thoughtfully designed. The dual fuel capability was one of the first features that ca...

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!

Powerful and practical!

[This review was collected as part of a promotion.] I'm so happy with this generator! It takes up less space than I had anticipated and is easy to store. It weighs just over 100lbs. Living in an area prone to power outages and wildfires, earthquake threats etc, and caring for animals requiring me to access to power at all times, it is really practical for me to have this on hand! It delivers exactly what I need, performs how I want without excessive noise, and doesn't waste fuel, which is a bonu...

Dual fuel generator

[This review was collected as part of a promotion.] With the weather been weird and the power go out quite often at my place. Receiving the generator is a game changer. Even though, it is about 111lb, but the generator come with wheel which it make it easier to carry around. This is a dual fuel, it can run in both either propane or gasoline. Easy to use with electric start, just push the button. It is easy to maintenance and its quieter than the other brand. I would like to recommend it.

Generator

[This review was collected as part of a promotion.] Generac Power Systems iQ3800 Duel Fuel Portable generator is very durable. Has a quite noise level. The push button on/ off doesn’t work. It may be the battery, but pull start works great. Easy to put oil in and maintenance is very easy to do.

Quiet, powerful and reliable - a dual fuel generat

[This review was collected as part of a promotion.] The build is solid, everything looks professional and well thought out. Started up from the first time! What I was particularly pleased with is that it is very quiet, especially compared to other models. It doesn't rattle, doesn't scare the neighbors, doesn't disturb my sleep. You can safely turn on at night. The power is enough for the refrigerator, and for lighting, and for charging appliances at the same time. Works both on gasoline and pro...

Good features and quiet running.

Would Recommend

Love the new generator, with an easy start electric starter. I went thru the process of adding the oil, etc. The generator arrived with a dead battery. I charged the battery , it started and ran quietly and efficently. l started the generator once a week just to keep ths system operational. My only problem is I need to charge the battery every time I go to start the generator. The battery does not hold a charge. The battery arrived needing a charge, and every time I go to start the generator I s...

Can work on both gas and propane

[This review was collected as part of a promotion.] I’ve never had or used a generator before so was super excited to get this; always wanted one. As you can see from our video it’s super easy to use! Just be sure to connect the battery, add oil then either use gas or propane and you’re good to go.

This dual fuel generator is a must for every home.

[This review was collected as part of a promotion.] My power goes out way too often due to trees breaking during storms. I have lost so much food as a result, so this generator will be a game changer. At over 115 pounds, it is heavy, but the compact size and wheels make transport easier. With four different power outlets, it means I can plug in appliances, cell phones and lights during an outage. Running on two types of fuel (gas and propane) gives me flexibility for usage. I like the LED displa...

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!
