DuroMax XP12000HX 12,000-Watt Dual Fuel Portable Generator - Gas & Propane, Electric Start, Whole Home Power Backup, Transfer Switch Ready, RV & Emergency Ready

So I owe this generator a review. 2 years late but better later than never.I only ever ran this on propane. it's never seen gas in its life.It starts strong. it runs smoothly. a little loud but it's a large open frame so comes with the territory.Moving it is okay its heavy again not a negative.I have it set up to run off of one of my 100 LB propane tank. It back feeds into the house through a 50 amp service. (please don't attempt unless you have experience doing this or consult with a local electrician) it effortlessly handles whole house AC. water heater and electric stove I switch off high demand appliances as needed but leave the small stuff on all the time.It starts good 90% of the time on electrical start reason I give it that rating is once in a while it backfires after sitting a while when trying to start on propane sometimes it has to try a couple times to start. Again this is not a red flag just feel like it should be said.Something else I noticed is the choke is electric. so you set it to choke before you hit set start button, and after its running it automatically moves the choke to run honestly did not know it did that when I bought it.For what is is definitely a solid choice. Last time I ran it I ran non stop for about 15 hours. then the main power came back on lol.

So received the generator with all the equipment as advertised, 15’ 3/4” natural gas line with brass quick disconnects, propane line and reg with dis connect, a complete set of plugs for the 120v-20amp, 240v-30amp, 240v-50amp. I was really surprised. Put the parts together and found I was missing the feet so I emailed the customer service next day during working hours and they responded within 20 minutes. Asked me my gen model, then told me to register the generator for future if any issues arise. Bam theee days later I had the two feet. Now installed she started up right away, first on gasoline, then after 20 minutes or so I switched over to natural gas and no problem she started right up. Note to all turn off natural gas valve when you go back to gas. I’ve ran the generator for over two hours so far just breaking it in. I emailed customer service asking if there was any recommendations on maintenance. They responded within 15 minutes stating after break in change the oil then since it’s a backup generator for my house they recommended run it for 15 minutes every month and hookup up a battery maintainer, even sent a Amazon link in the email for a suggestion. Very nice, I responded already had hooked up the pigtail on the battery for my maintainer and bought a metal gen house for permanent storage and weather protection. Must say customer service was great, generator runs great so far. Think it will go along time for me. Must have been a Wednesday build because I have had no issues to date. CS Email during working hours seems to be the perfect time to communicate. Noise is semi loud but it’s a 500 cc motor, battery was fully charged when received. I tried to charge it once I opened the packages but after 7 minutes charger was sold green so it was at 80% already. Heavy but the handles and wheels makes it easy to move, I would say with the discount $1999.00 was a great value. Knob to switch fields is very stiff so will turn it every month when I run it just to work it in some. It’s a good bang for your buck today. Will give more feed back after 10 plus hours.

This item works well. We got it because we loose power all the time when it's windy due to the power company turning off power for days due to increased risk of fire. This generater makes life so much more barable for the kids as well as keeps our food cold. It's easy to move so we can just move it out back when the power goes out. It's easy to start. It is a bit noisy but no worse than any other gas powered generators. It can run multiple appliances and electronics at one time. Greatful for this generator.

Okay, you are clearly eyeing the HXT version of this generator to run natural gas…or at least have that option, right? Otherwise, you can spend significantly less and get the dual fuel version.If you are like me, you would like something that runs off natural gas, similar to a whole-house solution…but without spending the $15K of that whole-house solution. This unit offers a good compromise. It is not as powerful as a whole-house generator, and it requires a bit of effort to get it up and running each time you need it, but it is far less expensive.My goal was to run the smaller of my two AC units, the associated furnace fan, and most other appliances (e.g., refrigerators) when we next lose power in the Houston area for whatever reason.I was comparing this option against the considerably less expensive Champion 100416 tri-fuel generator, which also looks well-designed.The problem with the Champion unit for my purposes is that, while the wattage is good enough, it only has a 30-amp outlet, which is likely not enough to start even my smaller AC/furnace fan. This DuroMax has a 50-amp outlet which definitely will do the job. Also, the digital gauge is a nice-to-have feature that will prove useful in assessing the load.However, the challenge with a bigger generator is that you do need a natural gas line with a hefty volume of BTUs…the manual says it consumes 225,000 btus per hour at full load. Initially I had the thought to hook it up to my existing 1/2-inch natural gas line on the back patio, which was originally installed to support a grill. However, most grills only need 50,000-100,000 BTUs per hour, and that 1/2-inch line runs a long way from the meter (thus lowering the volume), so that connection seemed likely to be inadequate.Instead, I decided to install a connection off of a 3/4-inch line that supplies my pool heater. The pool heater requires 400,000 BTUs per hour, so I knew that that natural gas line would provide enough BTUs, and the existing regulator was the appropriate size, too (6.0 - 9.0 inch water column according to the manual, which you can find on the DuroMax website).Anyway, I mention the above because I am a very average DIYer, and I had to think through these considerations carefully.Other lessons learned…You are going to need about a quart of 10W-30 SAE motor oil. I don’t know exactly how much because I combined two partial bottles. The point is that it does not come with the oil, so order some if you do not already have it.I also would recommend a trickle charger in case you do not fire up the generator very often. Trickle chargers are cheap and will keep the battery in healthy condition.It helps to have your own tools when taking off the shipping brace, putting on the wheels, et cetera. For example, having a socket wrench made some steps easier. I felt like the supplied tools were a bit lacking.The biggest challenge I faced was that the natural gas hose came with what appeared to be a 3/4-inch to 1/2-inch reducer attached on one end, and goodness gracious was mine on there tightly! It is nice that it has that reducer for those who plan to screw it onto a 1/2-inch gas line, but I didn’t need it, so I had to take it off…which should have been quick and easy…but was not. It took my (admittedly inconsiderable) strength as a 48-year-old guy with a 24-inch pipe wrench and a 12-inch crescent wrench (a.k.a., adjustable wrench) to break it free.Once I had it hooked up to my natural gas supply and the switches in the right positions, I pushed the start button. While the battery did its bit, it failed to crank. It would automatically stop trying after a couple of seconds, then it would automatically retry after a few more seconds. It did this 4-5 times before it finally caught and began to run. Was this because it took a little time to fill the hose and “prime?” I am not sure. I just mention it in hopes offering comfort if your unit does not start on the first attempt either.That’s as far as I’ve gotten at the time of this writing because I still need to have the interlock kit and 50-amp receptacle outlet installed on the house. If I learn more that I deem valuable, I will provide an update.Hope this helps!*********Update: I did get the interlock kit and 50-amp receptacle outlet installed, and I am happy to report that this setup did the job of running my smaller AC unit, two refrigerators, and all the small stuff in the house (lights, two computers, Internet modem/router, ceiling fans, et cetera). With all of that going, it showed 3 out of 5 bars...so approximately 60% load. Time will tell how well it holds up, but for now I remain pleased with this generator. Well done, DuroMax.
