GENMAX Portable Inverter Generator, 3500W Super Quiet Gas or Propane Powered Engine with Parallel Capability, Remote/Electric Start, Ideal for Camping Travel Outdoor.EPA Compliant (GM3500iAED)

This generator is perfect for my needs! I was looking at the larger 240 volt inverter generators on the market to power my house during extended power outages. I decided this GENMAX GM9000iED has the most features for the best price compared to any of the other similar generators in this category. For example, if you compare this GENMAX 9000 iED generator to the Predator 9500 watt inverter generator offered by Harbor Freight:The GENMAX has a full digital multi meter showing power usage, the Predator only has an hour meter.The GENMAX has remote start, the Predator does not.The GENMAX has an engine oil filter screen, the Predator does not. (as far as I know, none of the GENAMX competitors have any form of engine oil filtration)The GENMAX is dual fuel compatible (gasoline and propane), the Predator is only setup to burn gasoline.The GENMAX has a 50 amp receptacle built in so no adapters are needed when plugging into large RVs, The Predator does not have this. (And I don’t believe any of the other 9000 watt inverter generators on the market have it, either… at least at the time of this review)When you compare the full asking price of the GENMAX vs the full asking price of the Predator, they are the same price. (at the time of this writing, Sept 2022) The GENMAX has a bunch more features for the exact same price as the Predator. I realize either one of these generators can be on sale at any given time but for conversation sake I am comparing full price vs full price to make it fair and even.I purchased my generator through Amazon and the home delivery company who delivered my generator did a great job. Because the generator is heavier than what the typical Amazon Prime delivery truck can handle, they ship the generator as “freight” to a local home delivery company in your area. That delivery company called me on a Friday afternoon. (My deliver was scheduled for the following Wednesday) The lady who called wanted to setup a time for the delivery. She asked if they could deliver it on the following Monday, but that didn’t work for me. We eventually settled on that Tuesday, which was one day earlier than was originally scheduled through Amazon when I originally placed the order. On that next Monday the home delivery company sent me an automated text to remind me of the Tuesday delivery, and to give me a timeframe when the truck would be at my house. On Tuesday my phone beeped with a text from the truck driver letting me know he would be at my house in 20 minutes. (This was right in the middle of the window of time they gave me the day before) Exactly 20 minutes after that text, the truck rolled up on the street in front of my house. Two guys unloaded the generator off the truck and rolled it up my driveway on a furniture moving cart and rolled it right into my open garage stall. The outer shipping carton (cardboard box) on the generator had a small puncture in the side from the tip of a forklift fork. I asked the delivery guys to stick around for a few minutes so I could insect the item before signing for it and officially accepting the delivery. They gladly waiting for me to unbox the generator and look for damage. I quickly discovered these generators are shipped in TWO thick cardboard cartons (not just one) and my inner cardboard carton was flawless and so was the generator itself. I signed for the delivery and the two guys said thank you and drove off onto their next delivery. It was a very easy and painless process. I would say between Amazon, and my local home delivery company, they have this oversized/overweight home delivery/scheduling perfected. It went very smoothly!I took both side panels off the generator and filled the engine with oil on one side, and connected the electric start battery on the other side, I then reinstalled both side panels and lastly I poured about a gallon of non-ethanol gas in to the gas tank and the generator was ready to start. On brand new engines I like to slowly pull the rope cord to move oil throughout the engine before hitting the electric start button, which is exactly what I did. Once I pulled the rope 3 or 4 times, I turned on the main power switch and hit the big round start button. I started right up and ran perfectly! I am still in the process of breaking in the generator so I haven’t completely loaded it down yet but I have been varying the load with two small electric heaters, and I’ve also been varying the engine speed by turning the low idle switch on or off every 5 or 10 minutes.I have also made sure that it will run pretty much anything in my house. I recently installed a power “inlet box” on my house along with a generator interlock device on my main panel. (Everything inspected and passed) My house is not very big and every light bulb is LED. I flipped the light switch on in every room along with my TV and refrigerator running, internet modem, router, desktop computer, driveway flood light etc…. and it was still able to kick my central AC unit on…. And I don’t even have an easy start kit installed. VERY impressive!The generator runs like a Swiss watch and is very quiet, especially for its size. I have it positioned in such a spot where I cannot hear it running in my house. This thing is the best product that I’ve purchased in a long time. I absolutely love knowing that I have a large enough generator to run pretty much my entire house during extended power outages, and it’s quiet enough that I won’t have to lose my mind listening to it run 24 hours a day during outages, AND it’s an inverter generator so it constantly puts out exactly 60 hertz at roughly 120 volts. Even with my home AC running along with a bunch of lights and appliances, this generator was still running at exactly 60 hertz and the voltage maintained right around 120. Perfect!I believe this is the best inverter generator with the most features that you can buy right now.If you’re looking for a generator like this for either camping or home backup, this is the one!

This is a good generator at a decent price point. It offers 3500W max, remote start and dual fuel... all for under $1000. It arrived quickly and performed as advertised. After a 30 minute break-in run and associated oil change, I ran it for brief periods to check that it would serve our needs with our travel trailer and it worked well. I drained the fuel, disconnected the battery, and put it away for the winter.We didn't use it during the camping season, but I needed it for an event in October, so I took it out of storage, refueled and reconnected the battery, and it started up, no problem. Then I did something stupid...UPDATE: I bought another of these generators and found that the manufacturer had redesigned the wiring harness for the battery making it impossible to connect the harness incorrectly, thus preventing my stupid mistake, which I will now - for posterity’s sake - describe:I disconnected the battery and then reconnected it a couple of days later when I needed to use it. Somehow, in an obviously delirious state, I connected the battery to the wrong connector (still not sure how I did that, but I am getting older) and it fried the circuit board electronics. I didn't realize it at first, and the generator wouldn't start. Then I saw the telltale white acrid smoke and I knew something was wrong. At first I blamed the machine, but once I discovered my error, I reconnected it properly and the generator started promptly. The electrical output tested properly and everything seemed to be functioning to spec except that the digital readout was no longer working.I'm not sure that I will continue to use this generator; I'm not sure how critical the digital readout is for overall safety and governance. However, I would buy again. But this time I will mark the two proper connectors so I don't do another bonehead mistake.

If I could give it less than 1 star I would. Used this generator twice before it shut down and would not run again. Per GENMAX support, I swapped a sensor - no luck. Then I took it to a mechanic that GENMAX directed me to only to wait months to hear back that the computer is bad and it is not worth repairing. All of this has taken over 6 months now. After all this, GENMAX tried to tell me I was out of the warranty period and they couldn't help. NOT TRUE, I purchased the machine less than a year again and there is a 1 year warranty.Now they are asking me to get a letter from "their mechanic" stating the issue and that it is not worth the cost to repair. Shouldn't they speak to their own mechanic to get the details they want?Anyway, as with everything else they have asked me to do I have complied and sent them the letter from the mechanic. Let's hope they finally step up and do the right thing and send me a refund or worst case send me a new machine.Come on GENMAX, it's been nearly a year and this hasn't been resolved. Stand by your products and do what is right!! I'll post again when I get the next response. Hopefully it's good news!!
