GENMAX DIY Open Frame Dual Fuel Inverter Generator, 4000W ultra-quiet 145cc engine,with Parallel and Series Capability with CO Alert, Ideal for Construction Job & Home backup power EPA Compliant

Hurricane Beryl hit 3 days ago, and I have been running this bad boy nonstop and I have been pushing it to the max. So far I have been able to run a window ac unit, a refrigerator freezer combo, a deep freezer, a 65” tv a T-Mobile home internet, three lamps, 4 phone chargers, levoit wind maker fan and a bunch of other things. Very fuel efficient and also runs great. Very noise friendly and easy to operate. I do experience a bunch of power glitches with the internet, but that’s only because I am pushing this machine to its MAX and then some. So for me, I have no complaints. I am so happy I bought this product and I will support it no matter what!!!

Out of the box I followed the setup instructions using full synthetic oil. Fired right up strong, ran for 5 seconds and shut itself down. I tried again multiple times and couldn’t get it to continue running. Always started strong though, didn’t sputter it would just shut down. Finally I was dissatisfied and contacted Amazon. Long story short they told me to dispose of the unit and they refunded my money. I ordered a similar sized Champion and am very satisfied.I tinkered with this unit afterwards and got it to run for a break In period by disconnecting the low oil sensor. After break in I changed the oil using full synthetic both times and did about a 20 minute test feeding my house, it worked great.A couple weeks later the power went out so I set up to feed this to my house, and it was back to Strong starting, and shutting itself down after 5-10 seconds.I put this one back in the garage and ran the champion instead for 2 days, Flawlessly. I still haven’t figured out what’s wrong with this one, but I’ve gotten 0 productive hours out of this unit.Amazon did right by me for refunding my money. But the hassle is totally not worth it. Do yourself a favor and order the champion the first time.

Bought this generator to use for my business (electrical contractor). Didn’t want to break the bank since they typically get trashed on construction sites and end up needing to be replaced semi regularly.I was very impressed with this generator the first time I took it out. The electric start cranked it right over and I was ready to go. The generator performed great, running a demo hammer and charging some cordless batteries while I had it, it was great on fuel compared to many other equally sized generators. Running it about 1/2 it burned about 1/4 tank of fuel.The noise level of the generator is what I would expect. It’s not an ultra quiet generator, but it’s not so loud you need 100’ cord to work by it. I was able to set it up a few feet away and operate my demo hammer driving ground rods. The demo hammer was much louder than the generator was.The pull cord for auxiliary start is a great feature in the event the battery fails.For the money, this generator is a great value. It’s priced close to the HF alternatives, but it gets drop shipped directly to my house to add oil, fuel, and head out.My only complaint is that I wish it had another set of 120V outlets, though it’s typical for a 6000w generator.

Showed up on time and very well packaged. Setup took about 15-20 minutes and it started right up and ran well. As far as noise goes, it's not quiet but I didn't expect it to be, at this price point. It is noticeably quieter than my 10 year old, much smaller generator. If you need power during an outage, everyone else is running a generator too. I'll reasses after our first power outage and repost if I feel differently about it.

The media could not be loaded. Edit August 21 2024Parts came. They sent new inverter panel and spark plug igniter. Took about 15 minutes to change out. All plug and play. Works perfect. My experience is they stand beyond there product.Edit August16 2024Been emailing customer service and they told me today my replacement parts should ship this week. Will update again when I have more info to share.Edit July 3 2024,Unable to start. Can’t get a spark. This is second time I ever used it. I reached out to customer service. Hopefully they respond. Generator less than year old. Can’t recommend right now. Will update review when I get this resolved.This generator replaces an older generator. This is the perfect size of power vs portability. Easy set up. Good basic generator that has what you need to power your house in an emergency with none of the extra electronics you really don’t need. For those that say it may be noisy, it’s a gas motor it will be noisy. That’s just reality. It’s outside and your inside so no big deal. I definitely would purchase again. It exceeded my expectations.

I love my generator, it is easy to use. It is a heavy, but the handles help out a lot. The push the start is awesome!

It runs and functions but it backfires from time to time, especially on initial start. I only had this for about a week and it started happening my second day of use. They were able to refund me for the item and refunded me my assurance coverage as well. Have to wait about 2 days before I can order another generator because I paid through affirm which kind of sucks, but looking on the bright side they told me to keep this one so if I get the generator repaired I'll have a good back up.

I ordered this generator yesterday and recieved it today, very good. I filled the crank case of the engine to the full mark with fresh oil, added gasoline and started it up. The problem is it will only run for 2 to 3 seeconds making this a non-usable generator. Whe n is stops ther is no CO light on of a low loi light on, it just stops. I have sent an email to the repair facility in California and left a phone message but, being it is Sunday there is no reply. So at this point I am very dissapointed. Hopefullu with can get it going soon and I can ammend this review.Unhappy in Michigan.Amazon refunded all of the cost, told me to despose or do what I want with the faulty generator.
