Duromax XP12000EH – Best For Home

The DuroMax XP12000EH generator is a very portable and functional solution to power your house or camper no matter what the weather is like outside. The generator has several features that ensure its reliability and efficiency of use. It provides medium and large-sized properties with a reliable, continuous power supply of over 11,000 Watts.

The product is composed entirely of metal and has a stainless steel finish for long-term durability. It is particularly corrosion and humidity-resistant, preserving the hardware from humidity and shocks. The Dual Fuel Electric Start Generator, which weighs less than 230lbs, is easily transferred and relocated thanks to its sturdy rubber tires, which reduce sliding and provide stability.

A high number of outlets are housed in the control panel. A 120V/240V 50 amp heavy duty outlet, a 120V/240V 30 amp twist lock, a 120V twist lock, and two 120V 20 amp domestic outlets are among them.

Because the generator has a starting capacity of over 10,000W, it warms up quickly and begins producing sufficient energy straight immediately. According to other Duromax XP12000EH Dual Fuel Portable Generator reviews, it can run for 7.2 hours on propane and 8.83 hours on gas. This amount of time is sufficient to restore power to a residence or trailer that has been shut off from the grid.

Massive Power Output

The issue with most portable generators is that they are often meant to be used on construction sites or in isolated regions where the user just has to power a few modest electrical equipment or appliances. Because their overall power output is far too low, most of them are not intended to be used as a home backup power source.

Larger electric loads can only be handled by high-duty portable generators. However, there aren’t many decent 10000-watt generators available, and they’re typically rather expensive. The Duromax XP12000EH is one of the few generators of its size that both performs well and is reasonably priced.

Its 12,000 beginning watts are more than adequate to power most of your household’s vital equipment without fear of overload. It can also power one of the most demanding electric instruments, a 230 Amp MIG welder.

Dual Fuel

Dual fuel generators are often a better option than single fuel generators. For starters, operating a generator on propane is less expensive than running one on gasoline. This will save you a lot of money on petrol in the long run.

Second, having two fuel options gives you greater freedom and longer runtime because you don’t have to continuously worry about recharging the generator.

On both fuels combined, the Duromax XP12000EH can comfortably run for about 15 hours (depending on the current load). This is a huge benefit during an extended power outage.

Dual Fuel

CARB Compliant

Following the recent California power outages that impacted over 3 million people, it’s not surprising that an increasing number of Californians are eager to invest in a dependable portable generator.

The issue is that many generators (particularly large ones) do not comply with severe California Air Resources Board (CARB) rules. As a result, they are unlawful to use within the state’s borders.

Fortunately, the Duromax XP12000EH meets all CARB requirements. If you live in California, you have the legal right to buy and operate this generator.


The runtime of a generator is used to determine how long it can generate electricity before shutting down due to a lack of fuel. We’re aiming for fuel economic efficiency because gasoline and propane don’t grow on trees.

Runtime is calculated by determining how long the machine will work at 50% capacity (4,750 watts for gas and 4,037.5 watts for propane). The XP12000EH has a runtime rating of 10 hours on a full 8.3-gallon tank while in gasoline mode. In propane mode, a 40-pound tank will provide you with around 20 hours of electricity.


The dry weight of this instrument is around 269 pounds, which is nearly hard to lift on your own for the typical individual. Loading this equipment onto a vehicle or RV might be difficult if you don’t have multiple helpers.

Once on the ground, however, you may move the XP12000EH to anywhere you need power by raising the grips and pushing/tugging. The solid-fill tires will never go flat on you, making it easy to navigate any terrain.

Quiet Operation

This portable generator will create around 72 dB of noise while running at half capacity on either fuel source – roughly the equivalent of a vacuum cleaner. Granted, vacuum cleaners aren’t known for being whisper-silent, but it’s still very quiet, especially when compared to other generators on the market.

Aside from the monotonous hum of the engine, much of the sounds produced by a generator are caused by unsteady legs that clatter against paved surfaces. However, because of the generator’s solid four-point construction (stands and large wheels), it will not sway back and forth and generate moderate tremors when triggered.

Electric Starter

Simply insert the supplied key into the ignition and spin it to start this machine. If there are no fuel or oil issues, the XP12000EH should start straight up. To turn it off, turn the key in the other direction. When the generator is turned on, the starting battery charges automatically.

If the electronic starter fails for any reason (low battery or maintenance difficulties, which are sadly far too prevalent for our comfort), you may start her up by pulling on the recoil rope.


The XP12000EH comes with two standard 120V 12-amp plugs for directly connecting appliances to the generator. In our inlet box, you’ll also find numerous alternative outputs for connecting the generator to an RV.

Depending on your home’s electrical system or the items you need to utilize, you may pick whether to give 120V or 240V electricity.

  • The Duromax XP12000EH has a massive 12,000-watt output with a dual-fuel function that allows you to use it on either gasoline or propane.

  • This generator is suitable for contractors that want a portable generator for the construction site.
  • The simple control panel and copper wrapping in the coils make it a dependable solution for the construction site or powering your house.
  • When running at maximum power, the generator may be rather loud.
  • The generator is also rather hefty and difficult to maneuver.



Duromax Generator Problems

Very Loud

One of the most significant downsides of this Duromax XP12000EH generator is that it works at 74dB, which is a drawback of having a strong generator.


Because it is a bigger generator, it is heavier at 221 lbs. It does, however, include wheels and folding handles for transporting.


Without a question, this heavy-duty generator is one of the most powerful on the market, but it comes at a cost. Despite this, we believe it is a worthwhile purchase given the number of years you will use it and the quantity of power it offers.

This workhorse is excellent for Household Backup and can power most household basics like lights, appliances, and even central A/C systems during any power outage, storm, or emergency event, thanks to its 460cc OHV DuroMax Engine.
