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

MY FAVORITE PRESSURE WASHER

In all honesty I was afraid to buy a gas pressure washer- I wanted electric just for some home diy projects like my garage floor. The price on this was unbeatable and so I bit the bullet and bought it. This works perfect and it’s super easy to set up and maneuver. I can’t say I’ll ever go back to a electric pressure washer as I really feel this unit will last the rest of my life time. It’s strong and I called their support cuz I broke my wand and it cracked. I had a replacement at my door step 4 days later. Great company, better product. Kudos to genmax

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.
