Dual Fuel

As global energy consumption grows at exponential rates, so does the demand for energy solutions that are both more environmentally responsible and more efficient. The DuroMax XP4850EH has a dual fuel system that operates on either standard gasoline or cleaner burning liquid propane which can more than double you generator's run time.

With the XP4850EH, 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. And unlike gasoline, propane can be stored for years without going bad.

Only as Strong as Its Core. The DuroMax XP4850EH unit features a 7 Horsepower, Air Cooled Engine and is designed with a Low-Oil Shutoff Sensor to protect the Motor. It offers the switching capability of running on Propane or Gasoline fuels. Built to offer more power and longer lasting durability, The DuroMax XP4850EH Generator has a Cast-Ironed Sleeved, 196cc Engine rated at 7 HP delivering a peak of 4,400 surge watts / 3,500 Constant. This is a sufficient amount of power that can handle an overhead Air Conditioner in a RV to basic house power.

Safe & Reliable Operation for Any UserDesigned for Safe and Easy Operation, the XP4850EH features a user-friendly, Electric Start, that's as simple as starting your car. It is also equipped with a recoil start in case of the battery being drained. Solid-Fill tires are also standard, they will never run flat, and high leverage handles that make it easy to transport over every terrain. The attached oversized noise reducing Muffler has a built-in Spark Arrestor for safe use in mandated camping areas and jobsites.

A steal

It is well built and arrived in good condition after coming from California to South Carolina. Assembly was very easy although the manual needs come correcting. I will always run mine on propane as I have had experience with hurricanes and emergency generators and finding and storing gasoline before. Propane can be stored indefinitely without deteriorating and you don't have to clean out the tank and carb. after each use. The only thing I feel that is missing is an idle position when the generator is unloaded. I run 2 refrigerators and switch off to an A/C unit if needed but these all cycle on and off and it seems wastful for the genset to be turning 3600 rpm when unloaded. Other than that it started on the first try with propane fuel, handled the loads I put on and never went above 69 db noise level (according to the app on my cell). It is put away and I hope I never have to use it. Just have to remember to charge the battery every few months if I don't want to crank it by hand.

Don't be shy about the quality of this produce

Product arrived in four days via FED EX Ground in great shape. Well boxed for shipping with padding. Easy to assemble, battery was fully charged, added oil, hooked up LP gas and it started right up. Very quiet compared to past units I had. It is nicely finished. I wanted something for storms to run my side by side and a window ac unit and this fits my needs. Like the fact that it used three types of fuel. Customer support was terrific when we checked order/shipping since we had a storm coming at us. Do not overlook this dandy unit.

Easy to assemble. You do need a ratchet wrench. I think this is a great value. I am now ready for a hurricane in Houston. I plan to only run on propane. Very quite. No stinky odor while running. It looks nice. I plan to keep it in my garage and roll it out to my covered patio for use. Quality looks to be very good.

Everything I expected (well not at first)

Product arrived packed well. Started up easily on propane. I have not gas yet. I plugged my travel trailer in and the generator breaker tripped when the A/C compressor kicked on. I emailed the service department, Matthew told me how to correct the problem and my generator does exactly what I expected it to do! Wasn't a problem with the generator, it was a problem with my adapter cord not being compatible, yet he still helped me through it. Great product and great customer service!

I purchased this generator last week and it arrived within the week. It arrived with some small dents to the frame from shipping, but no structural damage to the main components. Not a issue. Today, I ran some function testing to see how well it will perform on the house during a power outage due to summer storms/hurricanes. Following the manual instructions and using a propane setup, the generator fired on the third attempt from the key start. i used the 240v connection, plugged into the transfer switch. I threw on each breaker 1 at a time so I could see/hear the load. No problems at all. This generator does EXACTLY what I intended/wanted. It will supply power to entire home(2000 sq. ft), with exception to the central ac unit. During an outage it will supply more than enough power to run all my essentials at the same time, the refrigerator/freezer, water heater, lights, tv, a portable ac unit and fans without a problem(my stove is gas). Keep in mind that during an outage, I dont need every light on at once, just the essentials to be somewhat comfortable. I have a 10,000 watt gas generator if i want everything in the house running at once. This generator is definitely quieter than most I've run across. I put it in the storage room, closed the door and can barely hear it running. I can't hear it running from inside the house or from the street(60 ft away), which I like alot. Draws less attention. It also burns much cleaner. I can hear my 10,000 watt generator from the end of the street and everyone for several blocks knows it's running. I am quite pleased with the performance of this generator and I am confident it will satisfy my need for power in the event of an emergency. The wheel attachment makes it very easy to move around and portable enough to just throw it in the back of my truck with a couple propane tanks and take it anywhere. Now, i'll have my propane provider run a line from my large tank in the back yard to my storage room so that I will always have sufficient propane on hand to get me thru any outage. And have gasoline as an secondary option

Happy Camper

This was better than advertised. Arrived in only a few days, and packed real well. I have used the unit several times now and on both propane and gas. Fires right up every time. Thanks again.
