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.

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!

General Power system

[This review was collected as part of a promotion.] I received the Generac iQ3800 from Influenster. And it’s been an absolute game-changer for backup power and outdoor use. The dual fuel capability (gasoline and propane) offers great flexibility, especially during emergencies when fuel availability can be unpredictable. Maintenance is easy. And it’s quieter than other generators.

just what we needed

Our power company has been putting in a lot of new equipment. Had one 4 day long power outage that cost us our ref. contents and a good reason to buy a portable generator. Works great but only needed to keep food cold. Can do wyfy and tv if needed too

Camping trips here we come !!

[This review was collected as part of a promotion.] Just got the Generac iQ3800DF Inverter Generator and I’m seriously impressed already. Dual fuel (gasoline + propane), super quiet, and easy to move around—exactly what I was looking for. The digital display is a nice bonus too. I can’t wait to put it to the test during our next camping trip or power outage! So far, 5/5!

Very quiet and easy to maintan

[This review was collected as part of a promotion.] I’ve been using the iQ3800 for home backup during storms and weekend RV trips—and it’s been outstanding. It kicks out 3,800 starting watts (3,100 running) on gas or 3,420/2,790 on propane, giving me flexibility when fuel is tight. Despite its power, it stays impressively quiet, so I can run it overnight without bothering the neighbors. Built with a rugged steel frame and protected outlets, it’s held up to bumps and rough handling, and the Eco‑M...

Powers on!

[This review was collected as part of a promotion.] This generator is a a solid choice if you’re someone who loves to go camping or even a good choice for a job site if you need back up power. It’s actually pretty quiet for a generator and I think it’s great that it can also be hooked up to propane.

Do not buy

Do not buy. I purchased brand new and it did not even start. Luckily the place I bought it from was cool and let me return it. That will be the first and last Generac product I ever purchase.
