There’s a reason why most homeowners opt for a portable generator despite its bulging underbelly – a much lower power output – portable generators are adaptable. Generators in this category are mostly pliable.

The makeshift setup process for portable generators is less intrusive and straightforward.

Also, you don’t have to spend a whopping sum to get the generator up and running.

Everyone would love to have standby generators as they offer more power, better performance, and improved functionality.

But they tend to come with their unsolicited baggage – a complicated setup process.

If there were a middle ground between both divides, the DuroMax xp 12000eh would be found in that category.

This unit is offering the best of both worlds – the portability of portable generators and the power of the standby category.

If it’s so unique, what makes it any different from the DuroMax xp10000eh and the DuroMax xp13000eh?

Does the DuroMax xp12000eh triumph over the Pulsar and WGen9500 generators? Let’s see the Duromax xp12000eh review.

Unlike the typical standby generator, the Duromax xp12000eh has a pair of solid fill wheels and practical handles so that it can be moved around without much fuss.

Don’t attempt lifting it on your own, as its weight will surprise you. Considering its numerous heavy-duty components, you shouldn’t expect it to be lightweight.

Its overwhelming portability makes this unit an excellent fit for anyone with several demands for a generator in different locations.

Dual Fuel Capability

Having a maximum power output of 12000 watts on a portable unit isn’t a familiar sight in the generator scene, but the xp12000eh is a different breed.

Since this generator uses two different fuel options – liquid propane and gasoline – it delivers to your home the efficiency of propane and the power of gasoline.

The multiple fuel sources of the Duromax 12000 watt generator improve its flexibility while saving you money on its running cost.

This makes it ideal for homes struggling with power outages due to a hurricane or similar natural unpleasantness.

Starting Mechanism

Starting a generator might be a burden for a lot of people, but households can depend on the electric start option on the 12000 watt dual fuel generator for quick use of the unit.

There’s also the recoil option if the electric start fails to deliver.


Due to the use of two different fuels, the runtime of the Duromax 12000 watt portable generator varies slightly with each fuel source.

When running on gasoline, the generator can keep your home powered for about 8 hours in one stretch. This will depend on the quantity of gas added to the 8.3-gallon tank and the load on the generator.

If you decide to use liquid propane fuel, this 12000 running watt unit keeps running for around 7 hours.

Were you stunned by the liquid propane runtime? Don’t be! The fuel source might be more efficient, but it tends to burn faster than gasoline.

However, its overall running cost is much more affordable compared to that of gasoline.

Use both fuel sources consecutively, and you have nearly a full day of constant power, which is bound to be something pleasant in an upsetting power outage.

Another outcome of the different power sources is the inconsistent running power.

If the generator is driven by gasoline, you get a running power of 9500 watts. Propane fuel delivers 9025 watts running power.

Those are huge figures for a primarily portable generator. Imagine all the appliances you could run with those numbers.

Noise level

With the use of generators, noise generated remains an issue regardless of how far a unit is from your property. The xp12000eh is no different.

Its 74 dB decibel rating suggests this could be a rather loud generator.

Considering its hefty capacity of 18 HP and 457 cc engine, it’s surprising that the noise level isn’t higher. Perhaps the rather conspicuous muffler plays a part in the lower noise level.


With generators, maintenance is something you shouldn’t joke with; else you could be spending huge sums just to fix avoidable faults or something worse like a fire hazard.

Using the 12000 watt unit, worries about the oil level and its impact on your generator don’t arise as the generator through its low oil sensor, shuts down the engine, preventing expensive damage.

And it’s easy to do this due to the convenient placement of the oil tank and the provided oil funnel.

You don’t have to open the fuel tank to confirm the quantity of gasoline left neither should you carry the propane tank to judge what’s left. The fuel indicator keeps you informed of the gasoline level.

If there’s the need to change or repair any of the generator’s components, you can use any of the tools provided.

From the spark plug wrench to the spanners and screwdrivers, Dyers are in for a jolly time with this unit.

Multi-functional capacity

On the side of this best rated generator for home use are four power outlets with different voltage calibrations for secure connection of tools and appliances.

This makes the Duromax xp12000eh an excellent option for use on job sites. You can just get the generator started and plug in your devices into the relevant outlet.

50 amp Generator

The xp12000eh has a distinct 50-amp power outlet so that certain power-intensive appliances can be connected to the generator directly.

You can also plug your RV directly to the generator, which explains the choice of this model by RV owners.

Job site workhorse

To reinforce just how compatible this unit is with job site functions, you can use the MX2 switch to bolster power output precisely for that heavy-duty tool, so you can get on with your work wherever the location.

Handy add-ons

To ensure you are fully conscious of the volt consumption of your appliances, there’s a voltmeter on the side of the generator.

If a change in output is not needed, the idle control keeps the generator running smoothly, which is great for places where the unit needs to be on standby.

Warranty Coverage

The Duromax xp12000eh comes with a 3-year warranty offer so that you can have repairs or replacements at no extra cost to you. But you’ll still have to report to Duromax before sending the generator back to the factory.

How can the Duromax xp12000eh Help Your Household?

If you’re not sure if this unit would meet your needs, compile the list of items used in your home. Once you have totalled the wattage requirement, compare it with the running power output of the xp12000eh, and you’ll be amazed.

This unit can support appliances like refrigerators, television sets, heaters, water pumps, tools, and others. You just have to take note of the watt demands of the device before using it on the generator.

The Pulsar 12000 Watt portable

Possesses a 16 HP, 457 cc engine capacity, which is compatible with its multiple fuel dependence – has a power output of 12000 watts peak with a running output of between 8,550 watts and 9,500 watts, depending on the fuel source.

Dual Fuel capacity – works on either gasoline or LPG, and you can switch fuel sources while the unit is running.

Switch and Go technology – equipped with Pulsar proprietary technology that lets you switch fuel sources by flipping a button without turning off the unit.

10-inch wheels and handles –increased mobility with its large wheels and concealable handles.

Digital meter – keeps you informed on the runtime numbers.

Westinghouse WGen9500DF

16 HP, 457 cc Engine – capable of running on multiple fuels – gasoline and propane with a power output of 12,500 watts peak and a rated output of 8,550 watts and 9,500 watts on propane and gas respectively.

Low oil shutdown – puts off the engine when its oil content gets to a damaging level low level

Dual fuel technology – allows the generator to run on two different fuel sources, just by flipping a switch

Electric start – lets you turn on the generator by touching a button. It features a separate engine shut-off switch.

6.6-gallon fuel tank – holds as much gasoline needed for hours of generator use

From the vantage point of an onlooker, all three generators could be confused for siblings. They have related attributes, from their dual fuel capabilities to the similar engine capacity.

The true picture begins to take shape when you look at their fuel efficiency. The Pulsar and Westinghouse models have a longer runtime.

Though the 12000 watt unit has a bigger tank size than their 6.6-gallon gasoline tank, these units are about to deliver runtime of as much as 17 hours of runtime on manageable loads.

I could run my appliances in a storm for a whole day, just by switching over to a filled propane tank.

Another discernible feature fitted on both models is the ease of flipping fuel sources.

Just by turning a switch, the Pulsar and Westinghouse generators can use a different fuel without you having to shut down their engine.

Having used such generators, it can be quite convenient to just switch fuel sources without turning off the engine. This isn’t the case with the Duromax 12000 watt portable generator.

The Pulsar and Westinghouse also have other performance enhancements not seen in the Duromax model.

I find the rubber covers around electric outlets on the Westinghouse unit to be something worth mentioning. Having had close calls with dangerous situations while using the generator, any safety measures on a unit is appreciated.

While the Duromax unit is offering an electric start, the Westinghouse model takes it a notch further with its remote start fob. I find such to be aesthetically pleasing, that’s for sure.

Initially, it felt like an even content, but that changed as a blow-for-blow assessment highlighted the inadequacies of the Duromax xp12000eh.
