Dual fuel!

I purchased this from Sam's Club online right when I saw it. I've been looking for something that had a propane option because its alot cleaner burn and it doesn't gunk up when you don't use it often. From receiving it, to unboxing it, everything was packaged and shipped well. They took their time with this one. Putting the wheels and handle on was a breeze. Genmax put everything needed to build and fully operate this amazing machine. Also it came with solid rubber wheels not cheap plastic wheels. Its very light and easy to maneuver. Customer service was great as well. I called to ask more about the generator and they were very helpful and full of knowledge. When you have customer service like that, thats how you know this is a great product. I followed all the instructions given and it started right up. It was very quiet and powerful enough to run my deep freezer and refrigerator for hours as I was performing a remodel in my garage. This is a great product and I highly recommend it.

4000iA Great purchase!

I purchased the GENMAX 4000 iA knowing that I needed to have a powerful, reliable and easy to move unit that could handle operating several things in my house if we ever had a power outage. I am glad that I made this purchase because an ice storm took out our power for 4 days. I set this unit up quickly to run temporary heat and lights, and it handled everything for the entire outage. Super quiet when it was in low idle mode and extremely strong when something demanded power. It ran about 6 Hrs. under heavy load with a full tank of gas. It started back up immediately after refueling with one pull, no problems! The weather was about 12 degrees Fahrenheit, day and night and the GENMAX was perfect! I have owned and operated many generators; this brand is incredible. If you need a small self-enclosed generator, get this product! It’s absolutely worth the money and built incredibly well. Strong, quiet and lightweight! Starting is so easy, which was important to me as well.

Sweet generator

I don’t normally leave reviews but this 10000w tri fuel is a game changer. I can use it to power my house, and it’s small enough to take with me for other projects around my property. Super easy to move around and relatively quiet for an open frame. I also like that it’s an inverter so I don’t have to worry about my devices being damaged. Love the 50A port- makes it easy to connect to my house
