DuroMax XP4850EH – Best dual fuel Duromax Generator


  • Dual fuel technology
  • Running watts (Gas/LPG): 3850 / 3273
  • Starting watts (Gas/LPG): 4850 / 4123
  • DuroMax MX2 power boost technology
  • Run time at 50% load (Gas/LPG): 12hr / 16hr (5 Gal)
  • Low oil indicator lamp and shut-off sensor
  • 7 HP air-cooled OHV engine

  • Heavy duty frame with four point fully isolated motor mounts

With dual fuel technology, this generator is a dream come true. The generator runs on both gasoline and propane, which could be beneficial especially when one fuel is unavailable, but the other is. Your use of either fuels would be dependent on knowing their pros and cons.

Propane as an alternative fuel is a step towards promoting the use of eco-friendly fuel as propane is a cleaner-burning fuel. However, propane is not best for use in extremely cold weather conditions as its regulator’s tank is susceptible to freezing, which makes gasoline a considerably better alternative.

On the other hand, gasoline produces more energy than propane does but is not eco-friendly as it does not burn cleanly. It emits a higher number of toxins into the atmosphere and leaves carbon deposits in the generator’s engine would could be harmful to the engine on the long run.

DuroMax XP4850EH-6

The XP4850EH has a flexible line which, at a frequency of 60Hz, allows it to connect to tanks of any size. It has a fuel capacity of 4 gallons and an estimated maximum AC output of 4,850 watts, making the generator fit to handle the power needs of most household items including air-conditioners and refrigerators.

As with all DuroMax generators, this has a heavy-duty frame built with cast iron sleeves. As a way of self-preservation, there’s an indicator lamp which lets you know when the oil is low. This feature is vital because oil, as a lubricant helps the generator run smoothly with little or no friction. Therefore, you should always know when to top-up.

There’s a key-start switch which, as the name implies, powers on the generator. This makes turning on the generator effortless. There’s also a circuit breaker which guards the generator and the facility it powers against damages that would have been caused by excess current due to overload or short circuit.

The model runs on an air-cooled DuroMax 7HP, 212cc OHV engine and you could choose between operating the generator at both 120 volts and 240 volts simultaneously, or at 120 volts only with full power.

  • It’s easy to start the generator

  • Reliable engine
  • As a hybrid generator, it gives you the flexibility of using either gasoline or propane
  • The generator is economical and supplies all the power you’ll need to run a household
  • The tyres and handles attached to the frame of the generator makes it easy to move around
  • Sturdy construction
  • A lot of users have complained that it’s difficult to fix the generator when it breaks down
  • Although it’s said to be guaranteed, it’s not the generator set as a whole- just parts of it. This means there are certain parts you’ll have to replace yourself should they need to be replaced even within the guarantee time.

DuroMax XP12000EH – Best DuroMax Generator for Home Backup


  • Dual fuel technology
  • Running watts (Gas/LPG): 9500 / 8075
  • Starting watts (Gas/LPG): 12000 / 10200
  • DuroMax MX2 power boost technology

Just like the previously reviewed generator, this generator also operates on dual fuel technology which gives you the freedom of running your generator on gasoline or liquid propane. The option of using propane helps you save money as research shows that propane is 33% more efficient than gasoline and less expensive.

DuroMax XP12000EH, alias ‘The Beast’, is powered by a 457cc, 18 Horsepower DuroMax OHV Engine which can produce up to 12,000 watts of energy that can comfortably carry the energy load of multiple appliances from as little as bulbs to high amperage power tools. The idle control, surge control, and low oil shutoff jointly contribute in extending the service life of this generator.

To save fuel and reduce noise, the idle control lowers the rotation per minute of the generator when it’s not in use. This generator also has an oil indicator like the previously reviewed DuroMax model, but unlike that model, this one shuts the generator off when it senses low oil level. This goes a long way in preserving the engine of the generator that would have been damaged by friction.
Another feature you’d appreciate is the surge arrest which protects the generator from damages caused by the interrupted flow of electricity (power surge). Without this feature, you’ll probably have to add a generator to your budget list every month.

DuroMax watts

It gets more interesting.The generator has two 120 volts receptacle and its MX2 technology ensures you get the maximum power outage from each of the 120V receptacle. This means you can decide to run the generator on both 120V and 240V simultaneously, or at 120V only with full power.

There’s a power panel attached to the frame of the generator which includes a wide selection of outlets for maximum compatibility. It includes a 12V direct current charging posts for charging external batteries. Other attachments located on the power panel are: one 120V 30A twist lock outlet, 1,240V 30A outlet 1240V 50A outlet and a 2,120V household ground fault circuit interrupter (GFCI) outlet, which is responsible for shutting off electric power when it senses an imbalance between outgoing and incoming current.

Running the generator on propane doubles its fuel life making it an efficient, low-maintenance solution for your home standby needs. With a full fuel tank, the generator can stay on for more than 8 hours.

The DuroMax XP2000EH generator is a super-efficient small generator set, weighing just 47 pounds but capable of generating up to 2000 watts of power! It’s a small but mighty model. It’s weight, handle and structure make it easy to carry around. The generator goes a step further in providing you with quality service with its inverter technology.

Inverter technology offers clean stable power for sensitive electronics and the benefits of high-quality output, higher fuel efficiency, quiet operation and parallel capability. What the last stated benefit (parallel capability) affords you is the luxury of bridging two smaller, lighter generators to do the work of a much larger generator. But to do this, you’ll need to purchase a parallel kit which is sold separately. This can cut on fuel cost that would have been spent on the larger generator.

This generator tows the line of the two previously reviewed models as a dual fuel technology generator. While running on propane, its running and peak watts respectively are 1,520 and 1900. On gasoline, its peak watt is 2000 while its running watt is 1,600.

DuroMax XP2000EH_4

Depending on the load the generator set has to carry, it can run for as long as 6.78 hours on gasoline and 21.46 hours on propane! The gasoline tank capacity of this model is 1.19 gallons, while its suggested that the suggested tank size of propane is 20 gallons.

Propane is usually a better choice of fuel because of its eco-friendly, economic and storage advantages. Gasoline is also a great choice because of its constant availability. However, gasoline not drained off but left in the fuel tank could cause complications to the generator.

To further reduce noise and minimize fuel consumption, the generator uses an idle control to lower its RPMs when not in service/use. You could also say the idle control puts the generator on economical mode.

The generator comes with propane hoses, oil funnel, regulators and a spark plug wrench. It operates on an engine speed of 4500 rpm and uses a 3 HP 80cc, 4 cycle air-cooled spark-ignition engine. Its power panel houses a 2120V household GFCI outlet.

This makes it a suitable generator for indoor and especially outdoor activities. Outdoor activities such as camping and working on job sites.

The engine generates power enough to handle multiple jobs requiring different power volume. That’s why it easily fits as power source for indoor and outdoor appliances. As an RV generator, it shuts down when the fuel tank is ¼ empty. This helps in two ways: it reminds the user to top-up fuel and preserves the engine life of the generator as forcing the generator to run on empty fuel could damage it.

DuroMax XP4400E -2

DuroMax XP4400E has two 120V receptacle, that’s a total of 240 V receptacle. It’s not necessary to run the generator using both at a time, but if you choose to do so you can. DuroMax RV switch helps you alternate between running the generator on both 120V and 240V simultaneously, or at 120V only with full power.

A full fuel tank of 4 gallons can run for 12 hours on half of its maximum rated load, which should be 2,200 watts. To make the generator easier to use and monitor, there are various meters and control buttons by its side. For example, the voltmeter helps you monitor the output range of the generator while its running.

These may be a bit confusing, so let’s explain their functions.

DuroMax XP13000E -4

The GFCI outlet protects electrical wiring and receptacles from overheating and catching fire. It also reduces the chances of electric shock. The concept of a twist-lock outlet is not complicated to figure out. The twist lock gets its name from the way the plug is inserted and twisted to keep it plugged in the generator. This way, the steady vibrations of the generator has no effect on it. The charging posts as its name implies are used for charging external batteries. Each of these outlets work as individual breakers to prevent overloading.

Additional features put in place to protect the generator are surge arrest and low oil shutoff. The former protects your generator from power surges which occur when electricity flow is interrupted, while the latter shuts down the generator when the oil level gets low. There’s an idle control which lowers the speed rotation of the generator when it’s not in use. This way it saves fuel.

Buyer’s Guide

Most people make the mistake of thinking that all that’s needed in investing in a generator set is the financial capacity. While this is a major factor needed, it is not the sole one. If do not want your generator to become a waste of money and space, there are certain factors you need to consider before adding any model to your shopping cart, especially a DuroMax generator.

The next section discusses those factors and they are arranged in no order.
10 Factors to Consider Before Investing in a DuroMax Generator

DuroMax XP13000E -1


You want to know the wattage of the generator, so that you can compare it against the amount of energy your appliances need to operate. It’s important to check this so you do not overload the generator.

Fuel technology

Some DuroMax generators can be powered by both gasoline and propane. Others run on only gasoline. If you need a generator that offers you that flexibility of choosing between fuels, go for the one with dual fuel technology, otherwise go for the regular/ single fuel technology.


The regular fuel type is gasoline, but if you’re not okay with using gasoline you can go for a DuroMax generator that uses propane as an alternative fuel. DuroMax XP12000EH and DuroMax XP4850EH would be wonderful choices to make.

6 Best DuroMax Generators

Fuel tank

The fuel tank capacity contributes to the running time of the generator, as that would determine how much fuel the generator will run on before a top-up.

Size and weight

Storage space should influence the size of the generator you’ll buy. If this doesn’t, mobility should. Smaller models of DuroMax generators, such as the DuroMax XP2000EH are usually easier to translocate and store when not in use.


Common start up options are key start switch and recoil. The key start switch is an easier alternative compared to the recoil. The recoil would require pulling a cord before the generator comes on. Some DuroMax generators use both methods, such as the XP12000EH model.

6 Best DuroMax Generators+2

Noise level

The expected noise level of the generator is rated in decibels. Your environment and neighbourhood should be put into consideration while deciding on which generator to get. If you’ll use the generator in a quiet environment, then amongst other things you should be intentional about getting a relatively noiseless generator.

Additional parts

Some DuroMax generators require additional parts which do not come with the generator before they perform certain functions. For example, the DuroMax XP2000EH earlier reviewed requires you to get a parallel kit. The parallel kit serves as the bridge between two small generators so they can function as a large generator would.

Standards compliance

To ensure the protection of human and environmental health, generators are designed with reduced emission engines, before they are approved for use by Environmental Protection Agency and issued a certificate to that effect.

Some states take this extra-seriously, such as California, so before the generator is approved and certified for use in that state it must meet the criteria of California Air Resources Board.

Most DuroMax generators are EPA and CARB approved and certified. This is often indicated in the product specifications, and when one certification is lacking it’s also specified.


All DuroMax generators have 3 years limited warranty.
