  • Overall, the DuroMax XP12000EH’s performance is reliable and efficient, making it a solid choice for a variety of power needs.

Power Output

The DuroMax XP12000EH provides impressive power output. It’s capable of producing 12,000 starting watts and 9,500 running watts on gasoline, and 11,400 starting watts and 9,025 running watts on propane. This makes it one of the most powerful portable generators on the market.

The generator’s power output is more than sufficient for most heavy-duty applications, including running large appliances, heavy tools, and even entire households during power outages. Users have praised its ability to handle multiple high-demand appliances simultaneously without any issues.

To give you a better idea of what this generator can power, let’s look at a table of common appliances and tools, along with their running and starting watts:

Item Running Watts Starting Watts
Refrigerator 200 W 1200 W
1/2 HP Furnace Fan 800 W 2350 W
Television (LED) 70 W 120 W
Laptop 50 W 75 W
10,000 BTU Air Conditioner 1500 W 3000 W
Electric Grill 1650 W 1650 W
Circular Saw 1400 W 2300 W
1 HP Air Compressor 1600 W 4500 W
Coffee Maker 1000 W 1000 W
Hair Dryer 1500 W 1500 W

The dual fuel capability is a significant advantage, providing flexibility and ensuring you’re never without power. Switching between gasoline and propane is seamless and doesn’t affect the generator’s performance.

One thing to note is that while the power output is impressive, it does come with increased fuel consumption. However, most users find this trade-off acceptable given the amount of power it provides.

In conclusion, the DuroMax XP12000EH generator offers a high power output, making it a reliable choice for those needing a powerful, versatile generator for various heavy-duty applications.

Run Time and Fuel Efficiency

The generator’s fuel capacity is 8.3 gallons when running on gasoline. This substantial capacity contributes to its extended run times, reducing the frequency of refueling and providing convenience for the user.

Comparison of the Run Time of DuroMax XP12000EH vs other dual fuel generators in the same class.

When it comes to run times, the XP12000EH performs admirably. On a full tank of gasoline, it can run for 8 hours at 50% load and an impressive 19 hours at 25% load. These figures place the XP12000EH above the average run times for generators in its class, which are 9 hours at 50% load and 17 hours at 25% load.

Comparison of the Fuel Efficiency of DuroMax XP12000EH vs other dual fuel generators in the same class.

However, the XP12000EH’s fuel efficiency is slightly below average. At 25% load, it consumes about 0.44 gallons per hour (GPH), which is just below the average of 0.45 GPH. At 50% load, its fuel consumption increases to 1.04 GPH, surpassing the average of 0.85 GPH. This higher fuel consumption is a trade-off for the generator’s high power output and is something to consider if fuel efficiency is a priority.

In conclusion, the DuroMax XP12000EH offers decent run times but its fuel efficiency is slightly below average, and it lacks specific fuel-saving features. This is why we are giving it a rating of 7.5 out of 10 in this category.

Noise Level

The DuroMax XP12000EH is not a quiet whisper in the woods, but it’s not a roaring beast either. The manufacturer advertises a noise level of 74 dBA, which is on par with the average noise level for generators in its class.

In real-world testing, the noise level was found to be slightly higher than advertised. The noise level was measured to be 89 to 90 dB at a distance of 5 feet under no load, and 75 to 77 dB at a distance of 30 feet under no load. This is a bit louder than the advertised 74 dBA, but it’s important to note that these measurements were taken under no load. The noise level may increase under load, but this is typical for most generators.
