The DuroMax XP4850EH Propane Generator is a powerful, gas and propane powered unit that will provide reliable power whenever you need it. It features the DuroMax Dual Fuel Technology that is now capable of nearly doubling the lifetime of your generator by being able to run on cleaner burning propane from a BBQ tank or main line. There are many advantages to running a Generator on Propane, including being easy to store, longer lasting and more readily available during disasters. Switching over from gas to propane is easy and is done so with a simple flip of a fuel switch. By using Propane, it will also give you quicker, more steady starts every time. It provides a constant 3,850 watts of power and a peak of 4,850 watts. This will adequately handle most household items needed in a emergency or power outage including refrigerator, lights and other basic necessities.

Also very important - gasoline degrtades faster then most people are aware of. We dont notice in our cars because that gas is USED. Unused gas can degrade in less then 6 months - a lot less. If you intend to keep it full of gas - nothing wrong with that - always add Sta-bil or some other gasoline stabilizer. Add it before fueling up - adding stabil to old gas does nothing and does not prolong the life of the gas. Stabil can increase the life of the gas up to a year (if you double the dose up to two years but that would be too long for me). Test the gen once a month without fail. As soon as the battery hiccups change it out...can expect one or two years from a batt . The reserve pull start is a great idea, don't forget though, to have about 20-30 feet of the proper size cord on hand to change it when it breaks, and the tools to do so...a 10 mm or 12 mm socket, long extension and socket wrench are PROBABLY about what you need.
Maybe a good idea to build its enclosure too. Small critters might try and find a home inside it and might even eat the wiring - not a good surprise either! If you make it a "doghouse" be aware, The gen must have air flow too, it will either have to be wheeled out of its "dog house" or arrangements made to open the walls, Another tip, might be a good idea to install an hour meter. For casual /emergency use you can probably get by without it and go by time as to when to change the oil. Use synth oil and change it once a year, or two.
I specifically purchased this generator to run on propane, but having the gasoline backup is a nice option. I'm very happy with the generator quality and performance, and I fully recommend the purchase. See below for my detailed review.
The generator comes completely assembled, except for the included wheel kit and handles that you need to assemble (and removal of a shipping block mounted under the motor). The kit also includes a couple tools (wrenches, spark plug wrench, screwdriver and funnel with clear tube). The generator has the propane regulator and connecting hose (about 3 ft long) incorporated into the engine, so the hookup is exactly like attaching LP tank to a BBQ grill.
Wheel kit and handles were pretty simple to install- no issues, all hardware was included. One note on assembly- the generator is shipped with the negative battery terminal wire disconnected to prevent the battery from draining, but nothing in the assembly instructions explain you need to reconnect this cable. The negative battery cable is tucked up under the gas tank, so you'll need to dress the wire down to the battery and attach- also simple once you know. I actually called DuraMax technical support because I thought the cable was missing. To their credit, I wasn't on hold that long, and the tech support answered my question quickly and was pleasant- so my experience was good. My battery was nearly fully charged, but I charged it anyway with a battery tender float charger before I attempted start the engine.
The generator ships without engine oil (and not included). You need to fill the motor with 20 oz of oil (I used 10w30 motor oil per the manual). Adding oil is a bit tricky because the oil fill is located on the lower side of the engine, but the funnel they included worked perfect, and has a clear plastic tube (about 12 inches long) that fits nicely into the filler opening.
Starting and running performance
I connected a standard 20lbs LP tank, primed the motor as instructed and it started and ran smoothly. I verified the 120VAC and 240VAC with a multimeter- all was perfect. I also connected a Connteck Y Adapter cable to the 240VAC (takes 240VAC twist lock into two 120VAC, 30A). I plugged in a 500W halogen lamp and let the generator run for about 1 hour, switching between 240VAC and 120VAC receptacles, flipping breaker on/off to verify load. All looks great. One note on the 12V DC output. This is for charging 12V DC batteries. The output actually measures about 20V DC, so if you're planning to run a 12V DC appliance, you could have trouble.
The conversation was a simple matter of installing a copper tube directly through the air filter into the carburetor. We did initially try feeding NG through the propane line but the propane tubing is not of sufficient diameter to delivery enough NG for generator to maintain a load. It took us longer to extend the NG line and quick connect set up than it took to convert the Gen from dual to tri fuel.
We are very please with the product and price. Next project, running lines to back feed through the electrical system so we can run a few important appliances with out the hassle of extension cords.
