Great little generator. Quieter than I expected. I had a Champion propane generator before this with the same decibel rating and this unit is noticeably quieter. The Champion generator struggled to run well on propane. The battery start on this unit is awesome. Even with its first start, it cranked up and ran in about 3 seconds. The propane hose is far superior than the standard BBQ grill hose that came with the Champion unit, it is longer and has a larger diameter passage for the propane. Setup was easy. The propane hose and a nice oil filling funnel/hose are buried inside the unit for transportation. I didn't see anything in the instructions about the oil funnel. The unit does not come with the required 20 ounces of oil, so go get some synthetic 10W30 before it arrives. I added an hours meter that connects to the spark plug so I can know when to change the oil. I bought two of these, one for my home and one for my cabin. I do not plan to use gasoline in either of them, ever, as gasoline is so hard on carburetors. I plumbed the one at my cabin to run off my 120 gallon pig. I included a picture of the MEC connector used to make the switch from the copper line to the quick connect. It is invaluable. Just a note, the regulator in this picture is not the good one that comes with the unit, it's the crappy standard BBQ one that comes with the Champion unit. The guy from the propane company recommended Duromax generators for connecting to a propane pig. I can see why. He has the 13,000 watt unit at his house. I can run everything at my cabin on 3,500 watts. It comes with the male and female 120/240 plugs so you can build your own extension cord to whatever length and gauge you want.Read full review

when I ordered the duro max 4400 I got it for 329. two days after I got it and found out it would verily run my air conditioner and would trip the breaker if I used the four prong reducer to three prong plug in four 30 amp but would run it with for a while on the 20 amp plug in. two days after I found it out I see the next size generator on sale for 299.

Assembly was easy and start-up was quick. Instructions were semi-clear, but sufficiently illustrated to make the job easy. Operating on LP, voltage output is steady and clean. Only issue from my perspective is that it is noisier than expected. The advertised noise figure for the "muffler" is probably correct, but the mechanical noise is louder than the exhaust noise, so could be a problem in some campsites. I suspect this will quiet down after some run-time since this is running right out of the box. Will update post later after some actual use. Over all - giving a pleased rating - would be five stars except for the clanging and rattle of the mechanical operating sounds.

Pulled it out of the box, then the smell of Chinese Factory hit. Next put on the wheels, handles, put in the oil, hooked it up to a propane tank, turned the key and she fired right up. It's not an inverter genny so it's a screamah' , but works well for the money. I have it as my back up for the Mutant, Zombie, Biker Apocalypse.... can't store gasoline in any large quantity. Propane stores forever. Update: I've been running for a few months now. (It is no longer my back-up). Since I'm off-grid with a solar set-up, living in the interior of Alaska and since the Sun doesn't really shine a lot during Dark Winter, the generator is getting run about 6 hours a day to keep my battery bank topped off. The 240V breaker is pretty sensitive and will trip off with motors requiring surge (like a Fridge) when my battery bank is charging. I've turned down the Battery Charger to about 70 amps DC, but even that causes the breaker to trip more than I would expect. Also consumption is kinda higher than expected. I've only run propane so can't speak to gasoline, but I'm averaging about 0.30 gallons propane an hour. a 100 lb tank filled with about 24 gallons of propane will last between 70 - 75 hours of run time or between 10 - 15 days. Depending on weather and charge rates. Another note, even brand new it consumes Oil. We have to make sure and check the oil everyday and usually have to fill the reservoir about once a week. Overall for the price........ well, you get what you pay for. For a little over $350 u.s. I can't really complain. At that price you an get two or three for same thing made by Yamaha or Honda. Also buy some ear-muffs....... Good lord is she loud!! Read full review

Seems to be a good generator: Have run the unit 3 times only so here are my thoughts. The oil filler plug/check level is very low to the ground which makes it hard to check properly. The provided funnel makes it easier to add oil but nothing for the checking. The battery disconnected cable is not mentioned in the instructions that I saw, at least on my read anyway. I have only used the unit with propane but so far so good. Seems to crank fairly quickly. It is quite noisy however.
