XP11000iH 11,000-Watt Dual Fuel Portable Digital Inverter Generator - Gas & Propane, Remote Electric Start, Transfer Switch Ready, RV & Emergency Ready

I've had this generator for several years now, its worked well for camping and our hunting shack. I've even used it to power the furnace and some outlets during a prolonged power outage. For its size it did a fantistic job! I'd highly recommond.

Extremely powerful, yet extremely quiet. Bought this to replace a Northstar 13,000-watt generator that was giving a few issues under heavy load (I suspect a failing breaker, easy fix), but also was extremely loud and fuel-hungry. This one is shockingly quiet, and even under heavy load it's probably half as loud as the old one. So far it also seems to be much more efficient since the inverter allows it to idle down and save fuel. Definitely need to turn off the idle down feature when running a welder off of it, otherwise the initial spark will surge a bit until the RPM's increase. but otherwise, I see no reason to ever turn it off. Did NOT come with oil, which was surprising but not unwelcome. I likely wouldn't have used it anyways as I only run Rotella T6 in all OPE.

I purchased the generator for my house in the event of a loss of power. It arrived well packaged and with instructions for a break in period. I followed all the instructions to a tee. The unit started fairly easy but was obviously struggling to maintain an RPM to generate power. Upon looking at the oil an excessive amount of metal was found in the oil. A claim was filed with them for a refund which they denied. Thet said SOME metal was to be found in the oil at break in. I have over 40 years experience with internal combustion engines, rebuilding, building new and repairing. I understand a small amount or material is to be found in the oil at break-in. The unit had been run at the factory so the metal left from manufacturing should have been cycled through the filter and caught by the filter then. something is self-destructing internally in this engine. They will not stand behind the product. Amazon will not stand behind their so-called A to Z guarantee. I have exhausted my claim and appeal opportunities for this and am now just stuck with it. Could I repair it myself sure. but after spending over 5000 dollars of hard-earned money why should I have to do that for a brand-new piece of equipment. All I can say is buyer beware! move to some other vendor for a better generator. I feel the price that is involved here is preventing a satisfactory outcome. I hope it is not the keep denying until they just get tired of trying scenario. If something changes in this process, I will update this review to reflect the results. Update: Amazon will not stand behind their warranty. I have provided pictures and professional opinions to no avail. The third party reseller will not respond. This item because it is an expensive unit has caused them to look for any loop hole to deny a refund. This is a shameful example of blatant disregard for the customer. DO NOT I REPEAT DO NOT PURCHASE THIS OR ANY OTHER UNIT FORM THIS RESELLER IR FROM AMAZON THE WILL NOT WARRANTY THE PRODUCT. Your 1 or 2 dollar items will assumably be handled with out issue but more oricy items are met with stiff unyielding defiant disregard for the customer. I. Now have a 5000 dollar boat anchor

Well packaged, good instructions, oil fill location obviously not well planned. You will have oil all over your garage floor even with their funnel. Started right up on gas, I’m running it now. Four hours in on 8 hours of break in. The delivery driver left it at my front door. Good thing I was home as it’s likely 250 pounds. My 82 year old wife could not have moved it and the theft of the generator would have been highly probable. You will need a hand cart! This gen set is quiet for one so large. I doubt the 61 decibels claim but it is tolerable in the daytime. Might not be acceptable at night as thieves would be prowling in a power outage. Great value for the Price.

I own 2 of these generators. I was so happy when I received my first one when storms hit. We were living in our RV while remodeling our home. We were out of power for 4 days and our 90lb propane tank would last 24 hrs. The next time the power went out it would not run. I replaced the regulator, no luck, had to run it on gas. I bought another one when they went on sale at Amazon to use for the house. The box was damaged and I probably should have sent it back. I unpacked it and the only damage I could see was the air filter housing was bent up. I called customer service and they sent me a new one. This unit was purchased in October 2023. We had 3 hrs on this one, connected to our 300 gal propane tank. It ran fine for the 3 hrs. and then shut down.I called customer service again and was told it was probably the CO sensor. So I replaced it and no luck. I've checked the oil level numerous times and replaced the regulator on this one too. No luck. We have been having power outages numerous times this year and so I decided to just go with gas again. It still won't stay running. Trust me, I have used the other one enough, and read the owners manual many times over. I know all the settings for either propane or gas use. I'm so frustrated at this point as we have more storms headed our way. We can always go to the RV as long as I have plenty of gas on hand. 5 gallons will last 8 hrs. I did a lot of research before settling on the Duromax, which has 4.5 stars, but now I have big time buyers remorse. So disappointed, one will run only on gas, and the other newer one won't run on anything.
