The demand for energy solutions that are environmentally responsible and efficient is high. The Durum XP4400EH has a dual fuel system that operates on either standard gasoline or cleaner burning liquid propane, which can more than double your generator's run time. With the XP4400EH, operating on propane will not gum up or foul your generator's carburetor, and will give you quick, reliable starts every time. It only takes a few seconds to switch over from regular gas to propane, and with the flexible line, you can easily hook up any size propane tank including the one from your barbeque grill. Unlike gasoline, propane can be stored for years without going bad.

Rated 4.0 out of 5.0 by Good Generator- Manual Needs Work I bought this as a backup for my home electrical system. I liked the idea of having the dual power so that I didn't have to rely on one type of fuel. The generator works great, but the directions need work. For example, the white negative battery cable is not connected to the battery when shipped and the it's hard to see that it's not connected because of where the battery and wires are located, but the instructions make no mention that the cable needs to be connected. It took me a while to figure out that it wasn't because that the battery was dead that the electric start wasn't working. The directions also show a picture of a regulator that you would normally see on a gas grill. I spent some time looking for the regulator and thought that they didn't include it, until I saw that the regulator was built-in to the generator. Once you get past the deficiencies with the directions, it's a very nice machine. Starts up right away and it is relatively quiet. The electric start and wheel kit are very good features. No problem running my gas burner, water heater, frig, freezer and tv, with some lights on at the same time. December 10, 2014
Rated 5.0 out of 5.0 by Great little generator IF you get one unbroken! Great little generator. Easy to assemble (because I had to do it twice). Runs great on propane. Easy start. Only drawback is that either the shippers or warehouse must have been playing football with these things. First one I got had a broken motor mount and a crushed air cleaner. I returned it to my local Home Depot with no problem. Called customer service and they were great! Sent another one out within a week at a 10% discount. Put it together today and the frame is bent up. I straightened it out as best I could and it sets level and runs great, so I am keeping it. I don't ever plan on using gasoline except in emergency so it should last for years! March 16, 2015
Rated 4.0 out of 5.0 by Not perfect, but a nice little fuel efficient generator. Good value, portable, convenient, and reliable (so far). I bought this because it is dual fuel and seems to be one of the better generators in terms of run time per gallon/lb of fuel. So far I am not disappointed. Had it for going on a year now and find it is very handy. It gets used to power an electric chain saw during the summer, and is backup power for the house the rest of the time. I am wiring a transfer panel for the house in a few days, so haven't had a chance to try a full load, but don't doubt it can deliver the specified watts. A partially half full 20# propane tank (BBQ size) has lasted for a few hours of use and still has significant fuel leftover. This fall It powered a couple of portable heaters (each on half power) during an overnight power outage. After around 10-hours of using a full 40# tank I can tell that some fuel is missing (compared to a spare full tank) but I think more than half remains. I have mostly run on propane, but the one time I ran on gasoline the governor seemed to have trouble keeping the engine at a steady rate. With propane it runs smoothly with appropriate responses to loading, but with gasoline it seems to have a cadence alternating between racing and normal (RRRRrrrrRRRRrrrr...). It powered okay, but I suspect the voltage wasn't so steady. Since I intend gasoline only as a last resort backup fuel, this hopefully won't be a major issue. I will try again to see if it happens again. Maybe it didn't like the fuel? Operation is a little noisy (as are most generators), but not excessively so. I plan to build a little sound barrier to park the generator behind. It is much quieter than the log splitter I used this summer, and certainly quieter than a gas lawn mower. Most of the noise comes from the engine rather than the exhaust, so a better muffler would not help much. I think some basic sound deadening material near the sides it would be enough improvement. We can hear it from the house, but mostly in the room nearest the generator. Everywhere else it was just a muffled background noise from outside. The fold down handles would be better if a little longer and as a single loop handle. The solid tires work as advertised. It is nice not to worry about airing them up. The electric start is very nice, no pulling the rope. So far starting has been 100% reliable. Read the instructions for choking, as it is not needed for propane unless doing a warm start (even at that I don't think it is needed). Choking is necessary for gasoline. Changing oil is mostly painless. There is room for a smallish shallow pan under the unit. The drain plug is on the side of the engine near the filler/dip stick. It drains onto the frame a little, but not all over, so a little wiping is all that will be needed. Putting an inch or two of spacer under the far tire speeds up drain time. Filling with oil requires a long funnel. There is no clock to log hours of run time, so one must be aware of run time so the mandatory 50-hour oil change can take place on schedule. I think it is good with any kind of 10-40 automotive oil. I am using Castrol synthetic blend. Also, these things burn a bit of oil, so be sure to check it every 10-hours or so. December 8, 2014
Rated 5.0 out of 5.0 by Generator Came complete with all parts and was easy to put together. Fired up on first try on unleaded and ran for a hour with small load. Then tested on propane with no issue. Just recently lost power for 30hrs or so ran it for about 15hrs powering fridge, freezer, tv and a few lights with no issues. Went through one BBQ tank cylinder. Happy with purchase and would buy again. October 28, 2014
Rated 4.0 out of 5.0 by Better than expected. So far so good. * LONG oil filler in the wheel kit so no issue like some have mentioned. Propane : Start at 1/2 choke then full choke. Noise : It isn't quiet, but isn't bat either. The directions are OK, but reading the reviews almost helps more. ( Like where to find the negative wire for the battery ) Also, they REALLY don't want you to fill the oil until you remove a block and bracket. I bet there are 10 different warnings about that. The battery on this unit was charged enough to turn it over pretty well. Read the manual, there is good info in it regarding operation. Don't assume you know everything. December 9, 2014
Rated 1.0 out of 5.0 by Buyer beware Product had multiple issues upon opening the shipping box. October 23, 2014
Rated 1.0 out of 5.0 by BYPASS THIS..NO WARRANTY AS YOU KNOW IT BEWARE there are NO repair facilities ---thus their warranty is useless when it breaks. They have no system of repair shops. You are totally on your own. They will if really really pressed send parts BUT they charge big shipping fees. really a hassle to deal with them. They are in laverne calif. They will not cover shipping of parts, will not cover labor..only the parts---IF you RE LUCKY January 1, 2014
Rated 5.0 out of 5.0 by Particularly like the autostart and dual fuel features of this generator. Assembly was easy and generator started easily. Bought this generator so I could run it on propane and store generator in my basment without creating a fire hazard. Autostart features is also nice to have especially for cold weather usage. Generator started easily on battery and powered my gas furnace, gas water heater, dehumidifier and freezer with plenty of power to spare. Quality is good and generator runs fairly quietly.
