the bad =I ordered this months ago and two weeks after the order, not hearing anything, emailed Overstock only to find out they did not have any. Guess they were never going to say anything. They refunded my money. Unfortunately, I had passed up buying elsewhere and now could not get one. In the end I was given 10% off after 5/6 emails with cutomer service uppers. Not a bad deal, but could have used it during the time I did not have it, and worst of all I could not understand how an "online" business could not track stock better. It came in about a week, UPS ground. Arrived on a wet day and had to sit outside. That proved not to be a prob though. However, somewhere along the line the box had picked up a crushed/ripped corner and there was different tape holding it closed; not a good sign. I assembled the unit as per instructions - just wheels, handles and removing some bracing. Hooked the battery to a charger for an hour, added oil and attached the line to my BBQ propane tank. It fired up on the second crank and ran smooth and quiet. Plugged in a shop vac and it worked fine. I was pretty pleased. A closer look though revealed that apparently the unit had been dropped on its end = the crushed box. Since it just has some soft 1/2" foam surrounding it the frame also had a serious dent to one end and the motor plate was dented. Not biggies - but, the air filter housing was also pushed back, collapsing the steel housing around where it fits to the carb and cracking the inner and outer plastic housing and bending the steel support on the bottom. Luckily no damage to the carb. I did my best to straighten out the housing, but either everything was shifted somewhat, or poorly designed, because there is no way to simply unhook the filter casing and remove to get to the filters for cleaning. It is right up against the steel frame. Since I am not going to use this except for emergency use it should not be a big prob - wont require many cleanings. Better packaging could prevent this though - and of course the idiots who handle this stuff. It is not something that can be easily repacked to send back, so I will keep it. I have emailed manuf to see if they will send the two parts that were broken, but I can't get them on in one piece anyway. Overall quality is Ok...typical import, nuts and bolts not real tight, cheap metal quality etc. But, for light use it fits the bill and the price was right. I chose this model due its ability to run on clean propane - leaves no residue in the carb or tank like gas, but can still run on gas if needed. I saw a Generac the other day in a store, they have an all propane model, quality is way ahead of this = much more solid visibly heavier parts, better powder coating on the frame. But, if you are going to use rarely/emergent than this should do the trick and this is a better price than direct from Duromax.

Ordered this Generator from Overstock and was delivered instantly. Unfortunately it was a bit damaged, pretty obviously during transport. Contacted Overstock and asked for replacement parts as the impacted parts could be easily replaced. Overstock bent backwards and went above & beyond with their customer service. Instead of sending the few cheap replacement parts they apologized and sent an entire new generator which also arrived quickly. The Overstock CSRs were very polite and helpful sorting things out via chat and email. It didn’t need a single phone call.
Some minimal assembly is needed to put the wheel kit on the generator - instructions and the tools provided are sufficient to get this done.
I ordered this to be prepared for the next “Sandy”. I gave it a dry run, hooking up my the heating system of a single 1 family house and the fridge. The generator took these 2 without a blink, no increase in RPMs 3500Watts are plenty. Tried it on a propane tank. It started instantly with the electric starter making it easy to use. Just following the instruction for the first time start, anyone should be able to handle it.
While Overstock is the seller, the phone number for potential troubleshooting that’s listed in the manual leads to Maxtools which gives some extra peace of mind, that this product is backed by a company who answers the phone and has knowledgeable people regarding the product. In the back of the manual is a spare parts list.
As for the price, you could get the same Watts for a bit less money, but the electric starter, included wheel kit, and the fact that this is a hybrid and runs on gasoline or propane is in my eyes well worth every penny.
I would buy it again in a heartbeat through Overstock, especially after the excellent custome service experience.
Had a hard time getting it to start the first time using propane. Turns out I had to increase air intake b removing the air cleaner. As soon as I did, it started right up. once it warms up, you can put the air cleaner back on. I like this because of the propane. Gas turns bad in a few months, but propane is propane for ever. Typically, people go to use a generator, and the gas has turned so it needs to be drained and cleaned. The propane prevents that because propane does not break down. keep the until clean, and dry and it should start every time. I am able to place this in the bed of my truck and use my RV propane bottles to run the unit. I've had many people ask about this generator because of the propane. I don't intend to use gas except for a last resort.
Purchased this after Sandy last year, as I had burned out my previous generator. This worked very well...but a few issues to look out for. 1 - I had this set up and ready to go but never tried it out before the recent ice storms that knocked out power across this region for a few days. My electronic start didn't work. Now I have to figure out if the battery is dead or if there is another issue. Good news, always started by the 3rd pull on the propane (and I am female and no powerhouse by any means). 2 - Because it was so cold, the propane tanks iced over and the generator had issues running through the full tank. During the day, I could get about 8 hours use on the 20lb propane tank, probably running about 50% load, but at night when it was very cold, i was getting 4 hours at best before the genny had issues sucking fuel out of the tank. I would assume spring, summer or fall use would be much better. Out of desperation day one I had to 'exchange' 2 tanks that certainly had a decent amount gas left in them, because I couldn't figure out what was going on. I figured it out by the 2nd day when we finally got power, and was able to get the tanks topped off rather than wasting money on an exchange. Next go around I'm going to need to figure out how to keep the tanks warm so the gas is better able to get to the genny in the cold.
The description says that it's a quiet run I'm trying to find out if its like the Honda generators we take the generator to Talladega for the NASCAR race and you have to turn generator off at 1100 if this is a quiet run I can run it all night longmariap01 on Aug 18, 2014Please enter a valid question.Answer This Question
Hello mariap01, this is a quiet-running machine, very similar to those offered by Honda. Have a great day!overstockcustomercare1 on Aug 27, 2014
Hello naturetopower, this does not have remote start. Have a great day! overstockcustomercare1 on Apr 22, 2014
Will product run on natural gas, or will I need to hook up a separate adapter. If that's the case, I'll just get the basic unit and buy my own 3- way adapter kit.clondike on Aug 6, 2013Please enter a valid question.Answer This Question

Received the Duromax 4400EH last night. All looks good but cannot locate "Owners Manual". Can you tell where it is hidden or must I download one off the internet.

Transfer switch to connect the generator to the main breaker panel house. Recommend this highly - it is far better than running cords all over the place, or back-feeding the main panel, which is illegal and very dangerous for linesman working on the utility company's lines.overstockcustomercare1 on Jan 11, 2013
