Known as “The Beast”, the DuroMax XP12000EH is the ultimate generator you can acquire for your food truck, packing a lot of amps and ultra-modern technology that allow it to work continuously from morning to sunset. It is exactly what you need if your business implies using lots of high-wattage appliances and if it is already heading to success, as this machine will allow you to take hundreds of orders and serve them all in time.

Dual Fuel Design

The truck is moving, so you have the chance to check the prices on fuel from one town to another and always get the sweetest deal. The fact that DuroMax XP12000EH allows using two types of fuels is a big advantage here, as you can simply shift from gasoline to propane if the offer is more attractive, or go from propane to gasoline if you are heading to a bigger event where you will need to plug in more appliances simultaneously.

Here are the specifications for each type of fuel:

  • Gasoline – produces more watts and gives the machine a higher start, so this is the type of fuel you want to use if you have invested in high-performance appliances that can cook a lot of food all at once. This unit comes with an 8-gallon gasoline reservoir that can run for about 8.83 hours at 50% load.
  • Propane – is cheaper, and this is one of the reasons people pick it, but the dissimilarity in the power output level is visible. For this model, you should use a 40-lb propane container, which will give you an average of 7.2 hours of use at 50% load.

Switching from propane to gasoline only takes 10 seconds, as you only need to disconnect the line that goes to the tank, press the button to purge the line, and then switch to the gas valve. The same goes for switching from gas to propane, so you can simply attach a propane container if you have one available when running out of gasoline.

Outstanding Power Output

A commercial deep fryer alone requires 1,500W, and if you start counting the fridge, freezer, range, griddles, microwave, coffee brewer, along with the systems that can keep the space sanitary and safe like ventilation or sprinklers, the amount of power you will need can easily go over 8,000 watts. So, yes, if you are serious about your business, you need “The Best”. And here’s what it has to offer:

  • Peak Wattage – this represents the highest amount of wattage the unit can produce before dropping to the rated value. This value cannot be held by the machine during the full operation, as it would quickly lead to overloading, but it must be high so it can power large loads. In this case, the surge power is 12,000W if the unit is used on gasoline and 11,400W if you are operating it with propane.
  • Rated Wattage – this is the value you need to bear in mind when calculating the number of watts you need to keep all your kitchen devices running. This model outputs an impressive 9,500W on gasoline and 9,025W on propane, being one of the strongest you can acquire at the moment.

It packs a 4-cycle air-cooled engine with spark ignition and a displacement of 457cc and uses the MX2 technology, which allows dividing the full power of the machine between 120V and 240V loads or operating it at 120V only while using full power.

5 Outlets Available
  • 1 x 120/240V 50A industrial outlet – use this option to power more demanding appliances like a high-wattage air conditioner or a heating source.
  • 1x 120/240 30A twist lock – still perfect for high-power appliances like a smaller AC, electric water heater, coffee maker, toaster, etc.
  • 1 x 120V 30A twist lock – the twist lock is perfect for essential appliances and systems that need to remain connected all the time, as this design prevents vibrations from disconnecting them.
  • 2 x 120V 20A home outlet – if you want to use the unit to power most systems and appliances in your home, you can use this option.
Heavy-Duty Build

This system is built to withstand intense use, and this is why the materials used for its construction are particularly durable and resistant to dents and rust. With an all-metal construction and all-copper windings, “The Beast” is basically indestructible. Even if it is heavy at 224 lbs., it can be moved around with the help of a set of heavy-duty tires that are designed never to get flat. Moreover, this machine comes with a series of protection mechanisms designed to ensure safety on-site and prolong its lifespan:

  • Low-oil protection function – if you ever forget to add more oil, the machine will shut down automatically to protect the engine.
  • Overload protection – it is advised to estimate the amount of wattage your appliances need so you don’t overload the engine, but if it happens to plug in more than it can handle, this function will turn it off before it overloads.
  • Voltmeter – it is mounted on the machine, offering precise readings of the voltage.
  • CARB compliant – the emissions are within the optimal standards, so this machine can be used safely in residential areas.

This model is backed by the company no matter if it is used for residential or commercial purposes. The difference stands in the time that is allocated for each case. Thus, if you will be using it in a food truck or for another business, you receive a 1-year guarantee. If this engine will be used to power the appliances in a household, the guarantee is 3 years.


  • Designed to handle large loads
  • Easy to switch from gasoline to propane and the other way around
  • 5 outlets included – one 50-amp outlet for heavy-duty use
  • MX2 technology allows switching between 120V and 240V use with ease
  • Defense against overloading and low oil


  • It is quite loud, considering that it generates an average of 74 dB
  • The instruction book is not up to date, and the directions can be confusing for a novice


Managing a large food truck? You need the power this machine can deliver. With peaks of over 10,000W and a rated power of over 9.000W, no matter if operated on propane or gasoline, it is a convenient solution that can keep all the cooking appliances operating optimally while providing the comfort of running an AC at the same time.

Another way to get free power and sustain your business can be through a portable solar power kit, which can help you store energy in batteries so you have a backup for your small appliances in case the main generator fails.

Problem Solution
Generator won’t start If you have tried powering your generator both by pressing the electric start button and using the recoil start system with no success at all, it’s time to go through the following checklist, as the following issues can be the ones causing the generator not to start:

  • Low on fuel – even if the fuel indicator shows that you have half a tank full, this may be just an error. It isn’t that uncommon for the mechanical fuel level gauge to stick and stop showing the real level. In some generators, even low fuel means that the machine won’t start, so do a quick visual check to see if the reservoir isn’t empty.
  • Water in the reservoir – if water is mixed with fuel, this will compromise its ability to burn, so your generator may not start. Always make sure not to fill the reservoir during rains and even in particularly humid days. If you suspect that water has entered the reservoir, empty it and fill it with fresh fuel.
  • Low on oil – most generators have an oil level monitoring system that shuts them off and prevents them from turning on if they don’t have enough oil. Check on your machine if the oil level is optimal, and add more if necessary. If the oil is not in good condition, you may need to change it.
  • Worn-out or damaged spark plug – check if there’s a crack at the porcelain insulator or if an electrode presents signs of damage or burning. A thick carbon build-up on the electrode can also indicate that the spark plug is defective.
  • Clogged filters – engines that use fossil fuel need air for the combustion to take place, and a clogged filter may stay in the way of the airflow. Check your oil and fuel filters and replace them if they are worn out. We advise always keeping a spare set of filters at hand.
  • Faulty battery – if you only use the generator once in a while, this can lead to lead sulfate accumulating on the plates of the battery and damaging it. If your battery is no longer in good condition, it is time to replace it.
Generator still won’t start If you checked and solved all the issues from above, but the engine just wouldn’t start, consider the following problems, which don’t appear as often but are still possible:

  • Defective fuel line – take a good look at the fuel line and check it for possible cracks or clogs that prevent the fuel from reaching the generator. Also, check the fuel filter that may be clogged and prevent the system from functioning optimally. Replace the filter and even the line if damaged.
  • Carburetor needs cleaning – if old, degraded gas is left in the carburetor, this can cause the unit not to start. The solution is to spray carb cleaner into the orifices.
Generator starts but doesn’t continue running Some of the problems that cause the unit not to start can prevent it from running after starting:

  • Clogged carburetor
  • Clogged filters
  • Low fuel
Generator runs rough The main cause, in this case, is that the carburetor is clogged. You can try cleaning out the old fuel deposits with a carb cleaning spray, but if this doesn’t solve the problem, you may need to replace the carburetor
Generator leaks gas Check the carburetor’s gasket. If it is dried out or missing completely, this can lead to gasoline leaking. Another possible cause may have to do with the carburetor float bowl gasket. In both cases, you will need to replace the defective or missing parts.
Battery keeps dying Your voltage regulator may not be functioning properly. This system has the purpose of ensuring that the right amount of voltage is sent to the battery so it gets optimally charged and doesn’t get overloaded. If the voltage regulator doesn’t work properly, the battery may not receive enough voltage, and this can lead to it dying off.
The appliance won’t start Plug it directly into the generator or use extension cords rated for your load. Additionally, make sure the generator can support the appliance you want to use it with.
It worked, and it suddenly stopped Depending on how many appliances you’re using, you might have overloaded it. Plug some of them out, and try again.
The voltage from the AC outlet is too low Make sure the generator runs at the rated speed. Additionally, make sure the slip rings are clean and check the connections between pins on the regulator. If it doesn’t solve the problem, ask for professional help.

Frequently Asked Questions

How big of a generator do I need for a food truck?
Running a basic food truck business usually requires about 3,000W, but if you are looking to equip your truck with everything it needs to bring you the biggest profit, you will probably need over 6,000-7,000 watts.

To size your generator, make a list of the appliances you are going to use, taking into consideration the number of watts they need to start and the number of watts they need to run. For example, a refrigerator will need an average of 1,250 starting watts and about 192 running watts, while a blender usually starts at 650 watts and continues running at 250 watts. After listing all the appliances you would need, add the starting watts on one side and the rated watts on the other to get the values your generator should output. Compare the values with the ones in the unit’s specifications and make sure to get a model that has a higher output than the one you have calculated, seeing how, as the appliances become older, they tend to draw slightly more energy.

What is the quietest generator for a food truck?
Generac 7127 iQ3500 comes with solid steel encasing and excellent insulation that allows it to function quietly, emitting only 44 dB. This small generator is ideal for food truck businesses that function only on basic appliances, seeing how it outputs 3,500W starting watts and 3,000W running watts. Conversely, it has one of the most reliable motors and comers with a good Generac warranty.

Can a portable generator power a house?
Yes. Some of the models we have selected are powerful enough to power the most important systems in a house in case of an emergency. Nevertheless, it isn’t advised to use a generator as a permanent energy source, as this can lead to it wearing out quickly.

What generator is best for a food truck?
If you are looking for a powerful unit that can power all the appliances you need to run your business optimally, we recommend the DuroMax XP12000EH, which is undoubtedly a beast. Packing no less than 5 outlets, of which one is a 240V 50 amp model, and being ready to function both on propane and gasoline, this model can easily adapt to any food truck configuration.

What is the lifespan of a portable generator?
Compared with standby generators, portable options tend to have a shorter lifespan. Thus, they are usually rated to last for 1,000 to 2,000 hours of functioning, which is nonetheless still a lot, considering that, in most cases, you don’t use them continuously but only when you need to use an appliance. Depending on how intense you use them, they can last from 10 to 20 years.

How long will a generator run on a 20-lb. tank of propane?
The duration is different depending on the load and the generator’s power. For an average model, a 20-lb. propane tank usually lasts 5.5 hours.

Is it better to run a generator on propane or gas?
When we take into consideration the amount of fuel that is needed to produce the same power output, it is easy to see that gasoline is the most cost-effective. It burns better and can generate higher levels of energy in a shorter amount of time. Even if propane is a bit cheaper, this doesn’t compensate for its lower power output. Nevertheless, propane is considered a cleaner source of energy, which produces fewer emissions and is easier on the generator’s mechanism, so by choosing it, you may end up replacing your unit less often.

Is it OK to let the generator run out of gas?
No. You should never let your generator operate until it runs out of fuel, as this can cause damages both to the unit and to the appliances that are hooked up to it. If your unit runs out of gas while operating, this can cause the coils to lose their magnetism, which will be drained by the powered appliances. In this case, the unit may not start the next time you need it.

Can you run an inverter generator in the rain?
It is strongly advised not to let your generator get wet or use it under pouring rain, as this can lead not only to irreversible damage but to life-threatening effects. If you need to use your unit in this type of weather, you will need to provide a waterproof shelter and make sure that water doesn’t get in as you start or turn it off.

Can a portable generator freeze?
In general, freezing appears at temperatures under 40F, and the part that is freezing is the fuel. To prevent this from happening, make sure to use large propane or gas tanks and keep them full. The higher the amount of fuel, the harder it is for it to freeze.
