Style: GM3200i
UPDATE 2: It has now been 2 years and 6 months since the purchase of this generator and it still runs great. It still only has about 80 hours on it, averaging my use to 32 hours per year. This unit is now at an even LOWER price than when I bought it making it a better deal. I make sure to use ehtanol free gas, run it for 30 minutes a month with load and change the oil every 40 hours. I would still purchase again. UPDATE: I bought this generator in April of '22 and it is now November '22. The generator has been great all summer and went on several trips to power our 22' camper. With the hour meter I installed, I've racked up 40 hours of run time and its worked great, running the trailers AC and anything else we've needed. I still recommend this unit for the money. I'm also getting about 4 hours of run time with heavy load. I’m going to compare this to the Honda eu2000 I’ve had experience with and a Wen4500 that I recently bought. -You wont find more generator for less money than this right here- This gen will run 2800 watts continuously (on the upper end) and will surge 3000(or 3200) depending on if you’re looking at the box or the machine. If you’re curious what it will run, look on YouTube. Gavin’s garage has a great video of its capability. This thing is quiet - my Apple Watch shows around 59-61db at 23’ in grass. Mind you this is on eco, but it’s about as loud as a window AC from that distance. It’s touching Honda territory with more wattage. For this price and wattage, you can’t get any better. I’ll be using this at camp grounds to run a 13,500btu camper AC and some other items. This is also a nice backup in case power goes out. My previous gen, an open frame Wen 4500, had all the power I’d need and about 20 more db’s. Most campgrounds don’t like that so this genmax is perfect. As far as portability goes, full of gas it’s about 56lbs and is easily totable with the handle up top. If you’re looking for a strong and quiet generator for any occasion, this should be on the list. Granted, it’s cheap price may mean parts are not as durable compared to a Honda, but most of the internals on these generators are made in bulk and just rebranded. I’ve had zero issues yet. One thing I do wish this gen had was a display with some info. I went ahead and installed a runlead hour meter (8$) on the top. This allows me to see how much runtime the machines had for break in and oil changes. I did a lot of research over a two month period to find the right gen for my needs and this fits the bill in almost every way. If you’re on the fence, buy it! ... show more

  • Excellent value
Style: GM3200i
After spending days researching and reviewing Generator/Inverters to use in our RV, I finally decided on the GenMax 3200. Initially I was leaning on smaller 2500 watt units, i.e. Champion, Generac, etc because I felt it would be enough to run the RV A/C, and because of the light weight of ~40 lbs, but all those units were just 80cc engines, and I knew the unit would have to always run on high speed mode to power the A/C. When I found this unit, I was impressed with the 145cc engine, the extra 500 watts, AND it weighed just 47 lbs. And the price was just $550. So I put it in my shopping cart and left it there for a few days to really think about it. All the reviews were pretty good, and there are some good youtube videos that praised it as well. I finally clicked the "checkout" button on Saturday, and it arrived today, the following Tuesday. Wow! And no damage. So I fill it with oil and a little gas, and after 3 or 4 pulls, it started right up. Hooked it up to the camper and ran the A/C fine, but being just 50 outside, I don't think the compressor ever kicked on, so a real test will have to wait a couple months although I have no doubt it will run the A/C just fine. I plugged in an 1875 watt hair dryer, and that got it's attention, but it simply speeded up it's RPM to accommodate for it. The vibration caused it to slide around a bit on our slick concrete porch at high RPM's. I am impressed with the build quality and so far, the performance. I'd rather buy domestic, but nothing comes close to the value of the Chinese units (as long as it holds up). I have had good luck with other Chinese generators & tools, as they have come a long way in their quality control, so hopefully I will have no regrets. Even the owner's manual is excellent without the typical bad grammer/spelling. Time will tell, but so far I really like this unit. It is the same as the SPERUS 3200 and the MaXpeedingRods 3200. As a plus, this unit will easily fit in the compartment under our RV bed as it 's just about 17" high, so I have about an inch to spare. Of course I will take it outside to use it. ... show more

  • Very Good
Style: GM3200i
At 7000ft it will not start with full choke. I have to turn the knob slightly back towards run, then it starts easily. It seems to prefer having the choke opened slowly once the ready light comes on. It did not come with a bottle of oil, but the included funnel works great. It stutters a bit when cold and/or no load... a better plug might help with this. Eco mode works great and it ramps up with load no problem. Runs smooth and strong with a decent load. The fuel tank is small and at 50% load I'm seeing about 4-6 hours per tank. Once I broke it and changed the oil it quieted down a bit. At low load it's very quiet, at higher loads it gets pretty loud. But if you need ultimate quiet at this power level you'll be spending a lot more. It's pretty heavy, but you can grab the handle with both hands so most people can probably manage it. Think carry-on bag full of rocks. Wheels would have been nice. ... show more

  • Quit working after 3 brief uses
Style: GM3200i
Bought this last year for an RV generator. Started first pull every time, also very quiet. Loved it at first. Unfortunately, after only 3 brief uses it no longer starts (less than an hour total usage). Spend your money on a better brand.

  • Nice Machine
Style: GM3200i
I purchased this back in Aug 22 for our travel trailer and very pleased. I needed something to generate 30a to run the trailer when we dry camp and it’s done the trick. I had one issue with the CO sensor, I call that the dummy switch for anyone stupid enough to run a combustion engine in a closed space. I emailed customer service and explained the issue and we only use it for our trailer outdoors and they responded next day with how to bypass the switch which I did and it’s running perfect again. I did a 3hr break in using racing grade moly oil with zinc and two oil changes during the break in period and installed and hr meter to keep track of run time for oil changes and other services. The generator has close to 100hrs of run time and starts the first pull every time. It’s not as a quite Honda but neither is the larger Honda in equal output size. It will run everything in our trailer and provides a constant 2800watts. We had a Wen 2200, also a great little machine but at 1600watts it would barely run the AC even after I install a soft start on the AC. That helped but you never want to run one of these at max output for any period because it shortens the life of the unit so I up sized and glad I did. I’ll keep the oil changed every 100hrs with synthetic and keep breather cleaned and I’m sure this unit will provide many yrs of service since it has steel cylinder sleeves. You can’t go wrong for the money we are very pleased with the performance. ... show more

  • Not suitable for overnight parking with big RV in hot weather
Style: GM3200i
We purchased this generator with the intention of using it with our 5th wheel RV for overnight parking at a place like Walmart. Based on the Amazon site description which stated "Capable of running for a long time for 8 hours in the case of 1 gallon of fuel, with "economy mode" for maximum fuel efficiency", we did not think this would be a problem. The first time we used the generator for overnight parking, we parked and turned on a single AC unit on the RV (it was about 95deg outside). It ran out of gas after about 75 minutes. We refilled it, made sure the Economy mode was turned on, and made sure nothing was on in the RV except for running the AC. It ran out of gas again after about 90 mins. Soon after that, it got too hot in the RV to sleep so we got up and got back on the road. This generator, contrary to what we understood from the description, does not last even close to 8 hrs, at least not when running a single AC unit in the RV. Unfortunately, the first time we needed it for this type of overnight parking was past the 30 Amazon return window. We then reached out to GENMAX for help. Although the response was not as timely as we would have liked and they did not agree to a return for a full refund, we did eventually come to agreement on a partial refund back to our payment method and agreed to review their advertising information. Based on this, and the fact that, other than realizing that a 1 gallon tank was just not sufficient for our big RV, we have no complaints about the generator. It worked well while it ran. We are amending our rating to a 4 star. ... show more

  • 3 years of dust, rain and snow and still running strong!
Style: GM3200i
I bought this generator back in 2022 and since then I have put it through hell and back. It is hands down the most reliable generator I have ever owned. I live offgrid out in the mountains of New Mexico and have left this generator out in the rain, snow, dust, and mud for the past 2 years and it has been nothing but reliable. Even now, I am writing this review from its power after sitting all summer with gas in the lines. It still started up on the 5th pull. I change the oil every 50 ish hours and has been just a straight work horse all these years. I don't write reviews often, but I can vouch for this generator...it's money well spent ... show more
