I bought this unit after my Champion generator took a dump on me. Just wanted to say this unit has been nothing short of Amazing! It has the necessary outlets and not the typical over complicated amount, as well as extremely portable! Good Job Genmax!

Free shipping and arrived in only 2 days. Got it out of the box and running in about 15 minutes. GENMAX thought of everything, tools, oil, and accessories were all included. The best part is the propane option no need to go get gas just grabbed the propane from the BBQ and got to work. First I hooked up my air compressor to test it out. The engine is so quiet compared to other generators. Loading in my truck was a breeze, it's so light and compact. Grabbed my welder and it powered it no problem. So nice to be able to weld in the backyard without needing 5 extension cords. You'll have a hard time beating this Genmax.

I read reviews on other Genmax models and decided to purchase this one. I recently used the generator to power up my jack hammer. I had to break up some old concrete at one of my rental properties. I had no issues. I did have to call tech support regarding the oil fill up. The phone tech was friendly and nice. I am very happy with my purchase.

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

I ordered the GenMax model GM5500XiD from Sam's Club. After doing some extensive research of similar models in this class/category, I chose GenMax. My primary reason for purchasing this particular generator was to have something in case of power outages, which are becoming more frequent. This is especially true for the hotter weather we are experiencing during the Summers in Southern California, followed by the fire season in the fall. This puts enormous pressure on the local power grid and we end up with our electricity being turned off, due to rolling blackouts or power outages in general. My family and friends also enjoy going camping about twice a year (Summer and Winter) and we attend numerous tailgate parties as we are huge sports fans. What I love about this particular model is that it allows you to run it on both propane and gas, which gives me the option to use either/or. There is also a button that allows you to transfer between Propane and Gas. For your accessories there is a 1AC 120V 30A outlet, a parallel Input, USB-A/C and an AC 120V 20A X2. The parallel input allows you to connect to multiple generators. That is a BIG plus for me. At 5500 watts, this generator fulfils all my requirements (refrigerators, portable AC, lights, all my small electronics, phones, laptops, etc.). The inverter also allows me to run sensitive devices without worrying about them getting damaged. The other feature that stands out is that this generator is very quiet. Even when I took it to a sporting event, tailgate party, and plugged in my television yesterday, I was able to have a conversation with my friends without having to yell. This unit only weighs about 55lbs and comes with wheels, so it is very easy to move from one location to another. It comes with oil, a 2 in 1 screwdriver, oil funnel and a spark plug socket wrench. All you need to do is open the box, remove, add the oil to the generator and you are in business. It's that easy! This generator is well designed and the construction is solid with no-flat wheels. For my purpose and needs, this is the ideal generator. The price point was perfect for my budget, is quiet and moves from one location to another with such ease.

By far the best open frame inverter technology generator on the market! Genmax is doing something right since these guys always seem to be ahead of the game with these new bells and whistles. This thing looks and feels sturdy too compared to other competitors. I have used many other manufacturer brands and by far Genmax is the way to go. The unit had arrived perfect and came with a bunch of accessories which was impressive. I was able to power up my skill-saw for some wood that I needed to chop up where no power was present. This generator powered up this 15 amp appliance with ease. You can’t beat the price and with 33 amps available at 120V. The best part is their support center is actually very knowledgeable for those who need help, and they carry all parts in stock! Sold!!!

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.

I’m really impressed with this product. It was easy to open from the box. Rubber wheels and handle were easy to put on. I like that I can use either gas or propane. It runs quietly and starts right away. I was able to use it for long time in my backyard while testing its use. I highly recommend this product.

This is great bang for buck buy, I don’t see anything else on the market that gives you more for your dollar than this pressure washer. I’ve had it for about 3 months now, broke the nozzle after a little bit , got a hold of the aupprt and they sent me all 5 nozzles again. No complaints

Generator was missing parts upon delivery. Genmax customer service was substantially lacking in both polite interaction and accommodation. Ultimately, I elected to have the entire generator exchanged through Sam's online and the original generator picked up for return. I can't imagine that this option was a cost benefit to either company (neither Sam's nor Genmax--and it's reputation). For those wondering, I never actually fired up the generator, so I am unable to speak to the effectiveness/functionality of the generator itself--apologies. The moment you add fuel/oil to a unit, Sam's and their delivery services get difficult about accepting (or how they accept) the returns, thereafter. I do give Sam's 5-stars for zero grief on processing the exchange--Thank You!
