Style: GM1200i
75 hrs in and this thing has been a life saver. I bought it as a just in case for a trip we were taking our camper on to run the A/C and charge the batteries because we didnt know if there would be a power hook-up, since our campers A/C unit only uses ~500 watts the GM1200i was the perfect size. The morning that the generator was set to arrive a plane took out some power lines leaving us without power and to make things better it was the hottest day of the year. The generator showed up about 1PM and I spent the next couple hours doing a break in of it. 1hr zero load, oil change, 1 hr 25-50% load, oil change, and then 1 hour 50-75% load and then an oil change. That was perfect timing as it was getting to the hottest part of the day when we could plug in the camper and use the camper AC and watch some TV to cool down and this generator did perfect. We did have it at about 900w for about 30 min while the camper batteries recharged and we ran the AC and the TV but once the batteries charged we went back down to about 550w and it ran all night until ~4 am when the power was restored. We did also end up needing it on our trip and we ran it at night and for an hour or so and during the day when we had to plug in laptops and such to do a little work and this generator handled it like a champ. It is very quite as we are unable to hear it in the camper even when it is just out side of the door, we even had someone stop by and comment one of the times we were running it during the day and about how quite it was even under 50-60% load. This generator is also really good on gas for the entire week we were out we only used right about 4gal of gas ( 4 of the 8 nights we just used to charge the batteries to run the inverter since it cooled off and we didnt need the AC at night). When we got there we had about 14hrs on it and we left with 74 hrs so that is about 15hrs on a gallon of gas at 25-60% load. The only con I have about this generator is that the plastic access panel for the air filter is very loose and will fall off while running, I put tape over the clips to hold them it just it was be nice if the clips were spread just a little bigger so they would catch better. TDLR: Very quite, does it job very well and it very fuel efficient. I do recommend doing some kind of break in process on it as the first 4 oil changes did have a good amount of glitter in the oil but by the 4th oil change it looked normal. I personally did oil changes every hour for the first 3 hours and then about every 25 hours after that. If you need a small generator to run lighter loads I don't think you can go wrong with this one.

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.

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.
