I bought this generator 2 years ago. I selected it as its an inverter generator with nearly 8000 continuous running watts and a 50 amp plug (don’t buy any generator that does not have this plug type). I wanted a generator that would run my whole house including one 3 ton air conditioner. 2 years later it was put to the test twice in 45 days. A couple of hints and tips on setting this generator up for whole home use. I have a large home and I have a device that tracks my average and max electricity watts used. The device is a Emporia Home Energy Monitor Smart Home Energy Monitor. With my pool equipment turned off my home uses ~6000k avg with one 3 ton air conditioner on. So the continuous watts on this generator has my use case covered (why spend $20k on generac?). To hook this up to my home I did the following and you can look up how to complete each step on youtube. 1. I installed a new 50 amp breaker in my main panel 2. I ran a heavy gauge wire from that new breaker to 50 Amp Generator Power Inlet Box on the outside of my house Amazon.com: Rophor 50 Amp Generator Power Inlet Box, NEMA SS2-50P for 3 Prong Generator Cord, 125/250 Volt, 12500 Watts, Weatherproof, Outdoor Use, ETL Listed : Patio, Lawn & Garden 3. I installed an interlock kit (a bunch of videos on youtube will explain what an interlock kit is and its use. Basically its for safety and easy to install) 4. On my AC that I plan to use during a power outages I installed a Micro – Air Easystart (again search youtube and learn why you need this. But without it your generator will likely not be able to turn on any large AC due to something called the “initial inrush” of electricity when an AC starts up.) 5. Finally, I bought a 50 Amp NEMA 14-50p Generator Cord Basically this DIY setup allows me to plug my generator directly into the new 50 amp breaker in my main panel and power everything in my break box (again I turn off my pool pumps and one run one AC when using the generator but everything else is on) In May 2024 my house power went out for 109 hours straight due to a storm. I ran this generator for all 109 hours continuously. No breaks and I did not shut it down once even when refilling it. This unit holds approximately 7 gallons of gas which for me lasted 10 hrs before refilling. My average watts used was ~6000 continuous so it was under heavy load the whole time. It never had any issues at all. My biggest issue was toting 5 gallon gas cans around (I have 7 five gallon cans). I changed the oil and washed the air filter after using it. In July 2024, luck would have it a hurricane hit, and I lost power for 90 straight hours. I turned it on during the end of hurricane and ran it for 90 hours straight with the AC on the whole time. Not one hiccup. It’s a beast and if you live in hurricane territory in the US and don’t want to pay Generac an amount equal to a new small car then I recommend this.

*UPDATED 6 Months Later* I am so pleased with this little generator. Since my original review of using this generator for running compressor and power tools, I finally had the opportunity to run it for the purpose I bought it for; running a small air conditioner at my no-power hunting camp. The generator performed exactly as expected, and was able to run the small 5,000 BTU air conditioner as well as some lights and providing me an AC outlet in my hunt camp camper for my phone charger for 6+ hours in 90 degree temperatures on the one gallon of gas. The generator is light enough for me to transport wherever I need it, so I have used it to run power tools on other "in the woods" projects to run my saw and nailer, electric landscaping tools and other plug-in equipment at my hunting stands. My latest experiment involved trying to run the electric systems on my 17" popup camper on this generator. With the 13,500 BTU rooftop air conditioner, as well as the Absorption-type fridge, and the main lights (2x LED banks) the generator was able to run everything. Once the AC ran through its start up cycle (large, temporary draw) and went to steady draw of about 1300 watts to run, I was able to run everything in eco mode, and did not overload the generator. I am incredibly pleased with the output of this generator and the small fuel consumption, small footprint, and relatively quiet operation. I would definitely purchase this again if I had need to replace this unit, or if I had increased power consumption. *ORIGINAL REVIEW* I purchased this generator on a Lightning Deal. It was a little bigger than what I wanted. I needed a small generator to run a 5000 BTU window AC on a camper I use at hunt camp. I was looking at the smaller Genmax generator (1200) but saw this one at basically the same price. This last weekend I had the opportunity to put it through its paces helping a friend build a cabin on a remote property he has. This generator was able to run a compressor (to run a framing nailer) as well as a chop saw for cutting dimensional lumber for framing, and a circular saw for cutting zip board. We even had an extra outlet we used to charge power tool batteries. The generator would struggle just a little bit if the air compressor and the chop saw ran at the same time, but it would catch up quickly and push on through. We ran the generator continuously for 6 hours on the single tank of gas. While its primary purpose will be to run the AC unit, I am now confident that I will be able to also run lights and perhaps even some appliances at the hunt camp trailer. The generator was quiet enough to be able to have a conversation standing next to it without really raising your voice. In fact, it was quieter than either the air compressor or the chop saw when they were running. All in all, I am very happy with its performance over the weekend, and I'm sure it will be more than adequate for what it was originally purchased for.

My Genmax 1200i was delivered yesterday. The packaging was in good condition. The generator was securely packed. Everything was in the box that was listed. I added oil and gas. It started I believe on the 3rd pull. Ran great with the eco on and off. Plugged in some test devices. It shut off after about an hr. Checked the oil- good. Checked the gas- good. Made sure the gas was turned on, I'm old, I forget lol. Started right up. Would run 15 min - 2 hrs and shut off. Contacted Amazon for product support. They referred me to the manufacturer after some stupid unrelated questions from their customer service. Contacted the manufacturer. Waiting........... I will update when or if anyone gets back to me. Right now I suggest you not buy a generator from Amazon. They don't care. Update: Still no response from manufacturer. I have not been able to talk to a live person, only leave messages. Update: It's been 4 days I didn't hear from the manufacturer. Called Amazon again 1st person transferred me, 2nd hung up after telling me nothing they could do. I called back, transferred. I was given a different number for the manufacturer. I finally got a real person. They are going to send me a new CO sensor. Nothing as of today. I guess I'm on my own. Received nothing. 3/26/2024 I suggest no one buy a generator from Amazon. They don't allow returns on any generator. You have a 50/50 chance of getting a generator that works. I can't afford them odds. I'm still able to charge my batteries, sometimes for 10 minutes sometimes I get an hr+. That's unacceptable. Will not run! This has been a piece of sh*t since day 1.
