    • Solid, heavy, durable, little noisy.
Style: 13,000-Watt Dual Fuel
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. ... show more

    • XP13000HXT Natural Gas-Focused Review
Style: 13,000-Watt Tri Fuel
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. ... show more

    • Very Nice Generator
Style: 13,000-Watt Dual Fuel
I purchased this generator to replace an ailing 17-year-old Aurora 6800-watt diesel generator. I purchased a Diesel model for the same reason most people buy propane or natural gas models; gasoline has a very short shelf life. I did much research, and it seems DuroMax has an excellent reputation for reliability and durability. I picked this model as the Aurora 6800 model couldn't run my heat pump and other things at the same time. Most complaints on the DuroMax models are related to noise and shutting down because of the CO sensor. It is a 20hp motor and is going to be a bit noisy, it is much quieter than my diesel generator. As far as the CO sensor issue many people believe the sensors are too sensitive, many complain of it being triggered even when running out in the open. I have only run mine for the 8-hour break in period so far, 3 continuous hours 1 day and the rest then next day with a 24-amp load and it didn't shut down. The CO sensor issue is not exclusive to DuroMax, almost all manufacturers are having similar complaints. apparently even if the wind blows against the exhaust, it can blow back on the sensor and cause a shutdown. You have to wait 5 minutes before it will start back up if that happens. Hopefully they will improve on this issue, there's always going to be people who will try and run a generator in their house or garage so I see the need, but I also will be very irritated if mine starts shutting down like that. I am happy with my purchase and recommend this model to others, I like it. ... show more
