Engine capacity and wattage

Just how big is the XP15000EH? In terms of size, it’s really a large one: 33 inches high, 35 inches long, and 24 inches wide. It’s also on the heavy side, weighing at a whopping 349 pounds. That’s no surprise, though, as it houses a huge, 713-cc, 23-horsepower engine capable of running on both gasoline and propane.

How much power can this engine produce? If fueled with gasoline, you can expect it to generate up to 12,000 watts running and 15,000 watts starting. It will run continuously on gasoline for around nine hours. On the other hand, if you use propane for fuel, it can provide you with 11,400 watts running and 14,250 watts surge for about eight and a half hours.

That amount of power is certainly more than enough to keep your lights and all the appliances you consider essential turned on. You can safely plug in your refrigerator and freezer, your washer/dryer unit, your TV set, your central air conditioning, your water heater, and even your electric oven at the same time. The genset has a surge protector that will shield it from tripping. Thus, if you have this machine, you probably won’t feel like you’re experiencing a power outage.

The XP15000EH is easy to start, too. Just like starting a car, you only need to turn the key provided or pull the crank behind the engine. The engine will keep running smoothly as long as you break it in properly with an oil change. DuroMax recommends SAE 10W-30 engine oil for all its genset models because it has the right viscosity for their design.

The one thing we don’t like about this engine, though, is the noise. At 84 decibels, this noise is just like what you’d hear if you’re sitting in traffic during rush hour. Unless you put it in a space that’s insulated against noise, it’s likely to bother your close neighbors.

Fuel consumptionduromax xp15000eh portable generator review

The XP15000EH is built with DuroMax’s very own dual-fuel technology. What this means is this machine can run on both gasoline and propane. So, you have the flexibility to choose which type of fuel to use, depending on your preference or what’s available.

On gasoline, this machine can power up your house for around nine hours. Its tank can carry up to 8.3 gallons of gasoline. On propane, this genset has about eight and a half hours of running time. Though you can connect this model to any tank size, DuroMax recommends that you use 60-gallon propane tanks.

The DuroMax XP15000EH is CARB- and EPA-compliant, so you can use it anywhere in all 50 states. Nonetheless, you need to take care if you’re going to use this product in a location that’s high in altitude. In such areas, this genset develops the tendency to use up more fuel more quickly and release more emissions. To correct this tendency, you can ask your dealer to fit your machine with a modified carburetor. This modified carburetor will also help maintain your generator’s compliance.


This portable generator xp15000eh is more than ready to help you do some heavy lifting. It has seven outlets that let you plug in a wide variety of tools and appliances: four 120V 20A GFCIs, one 120V 30A twist lock, one 120/240V 30A twist lock, and one 120/240V 50A heavy duty. You may find the 50A outlet particularly useful if you’re an RVer. With this outlet, you can use this Genset to supply your RV with electricity if electric hookups aren’t available at the campground you’re parked at.

Ideal usage

The XP15000EH is primarily a backup generator—one to help you keep your household’s appliances and electronics running normally even in the event of a power outage. Your lights can stay on all night if you wish. You can cook on your electric stove or oven. You can stay cool in summer with your air conditioning on, or keep warm in winter with your heater. And you can watch TV, use the internet, charge your mobile devices, and do whatever else you need to do with electricity even when the power grid is down.

If you’re looking for a power generator to supply your worksite, you’ll get plenty from the XP15000EH model. You can readily plugin your power tools, even the heavy-loading ones. And you can even use them at the same time as long as you pay attention to the generator’s wattage limits.
