10 Best Generators for Food Truck – Reviews & Buying Guide

We reviewed today’s most popular portable generators commonly used in the industry and shared our experience so you can easily make your choice.

Top 10 Best Generators for Food Truck

01 DuroMax XP5500E Portable Generator (Editor’s Choice)

DuroMax XP5500E Gas Powered Portable Generator

Why it Stands Out To Us

The DuroMax XP5500E is your best bet if you’re eager to take your business to the next level with a highly productive food truck. Compared to the price, its impressive features are a delight for first-time restaurateurs on a budget.

You will find that this generator can run for many hours, with no complications, as it is super reliable and easy to service.

Since it is an inverter generator, not a conventional one, it makes far less noise.  This model has a powerful 225cc engine with specialized surge power protection. It is all metal, has a motor with copper windings and a specialized GFCI protection outlet.

Our Experience with the DuroMax XP5500E Generator

  • We have chosen the generator as the ‘Best Choice’ because it is incredible for its price and runs flawlessly!
  • We have used this generator to run all our appliances except 220-volt appliances; this included our fridge, lights, microwave, cooker, coffee maker, and other smaller devices. It can run for 72 hours at a time without a problem.
  • Having an electric automatic start button is very handy! So it is easy to start and runs effortlessly.
  • The DuroMax XP5500E not only burns fuel but propane as well. This 20lb propane cylinder can manage 11 hours of constant running.

What We Didn’t Like

  • Other than its sturdy metal frame, this model has poor quality neoprene tires, which went completely out of shape, making moving the generator difficult.
  • We found the user manual exceptionally vague and unsuitable for a novice. The illustrations in the book are useless as they are too small and have a low contract, making the pictures challenging to see.

What Could Be Improved and Why

  • The manufacturer could improve the instruction manual to make it easier for novices to use it properly.
  • They should consider using better quality wheels that don’t lose their shape, which will improve the mobility of the generator.

This model is highly powered and would be an excellent generator for a food truck company that runs many appliances and is a high volume food business.

Our Experience with the Westinghouse WGen9500DF

  • We found the WGen9500DF generator well built and high-powered. It runs all our appliances effortlessly—for example, air-con, heater,  refrigerator, freezer, microwave, cooker, and other smaller devices.

What Could Be Improved and Why

  • Since there are no visible oil level markings, it is challenging to top up the unit with crankshaft oil.
  • The dipstick has no making, so it isn’t easy to gauge the oil’s level or at what level the oil should be.


  • Dimensions: 27.2×26.1×26.5 inches
  • Weight: 220.00 lbs
  • Battery: One
  • Fuel Tank: 6.6 gallons

03 Generac 6864 Diesel Powered Portable Generator (Top Diesel Unit)

Generac 6864 Diesel Powered Portable Generator

Why it Stands Out To Us

If you are a client needing a diesel generator to run your food truck, the Generac 6864 diesel-powered portable generator is one of its kind.  This unit has the same amount of power as a 10K generator, which is very affordable.

Not only is it known to be high-powered, but it is sturdy and robust.  The unit runs at 5000 watts, so it is powered to effortlessly run all appliances on your food truck.

What We Didn’t Like

  • This unit did not come with a battery. A battery is required to operate the cut-off fuel system.  We found that the battery was strong enough to start the generator using the pull-start, which is a definite
  • Since it has no wheels and is heavy, we would advise you to buy a wheel kit so that you can maneuver it around.
  • We have found it relatively expensive to run, and it makes a lot more noise than most generators.

What Could Be Improved and Why

  • A battery could be part of the deal, for convenience’s sake.

04 Champion 6250-Watt Open Frame Inverter (Top Inverter Unit)

Champion 6250-Watt Open Frame Inverter

Why it Stands Out To Us

This top inverter generator is excellent for a large food truck with many high-powered appliances.

Although this unit makes a fair amount of noise, it is quieter than most generators.

What is advantageous is the economy setting, which can be used during quieter moments.

Food truck owners, who move around constantly, moving from one venue to the next, would greatly benefit from using this generator.

Our Experience with the Champion 6250-Watt Open Frame Inverter

  • We found this generator and an excellent option for our food truck, which is constantly on the move. This top inverter unit is lightweight and easy to carry.

  • This unit does not have an electric start button. Some people find it challenging to start up using the pull starter, especially women.
  • The quick-start manual is not comprehensive enough, and it is essential to read the proper manual when buying this model.

What Could Be Improved and Why

  • We recommend that Champion improve their quick-start manual so that new customers do not miss out on essential start-ups and set up steps when they first use their generator. There is no mention of removing the shipping restraining hardware in the quick-start manual, or the breaking-in period, before actual use.
  • Another improvement would be to install an electric start to this model.

Why it Stands Out To Us

This unit is extremely quiet!  It runs efficiently with hardly any noise.  This model will benefit food truck owners who camp at public venues, and a low noise factor is needed.

What We Didn’t Like

Best Generator for Food Truck: A Buyers Guide

Generator for Food Truck Buying Guide

How quietly it runs:

  • When buying a Food Truck generator, you need to consider a unit that runs quietly. If you are operating in an area with other food trucks or residents, for example, at a public venue, the quieter the generator, the better.
  • A quiet generator will operate in the 50 dB range to about the 70 dB range. Inverter generators are quieter than conventional generators.  The reason why an inverter generator is quieter is that it uses technology that uses clean electricity.

Best type for generator:

When choosing the best type of generator for your food truck, there are different factors to consider:

  • As your food truck operates on a daily basis, it is best to consider buying a good quality unit, which is highly efficient and affordable to run.
  • You also need to consider what type of gas the unit uses and whether it offers two types of energy. For example, whether the unit can run on propane and fuel if it runs on diesel or gas.
  • One significant factor to consider is the generator’s overall power. You don’t want your unit to be insufficient and not able to power all your appliances.

Size of the generator:

The size of your generator is an essential factor to consider.  The size of the generator will depend on how many applicants you have. Listed below are the applicants you may use and the average watts of each applicant and starting power of reactive load appliances:

  • Mini Refrigerator: 400 to 1250 Watts / 1250 (Starting Watts), 192 (Running Watts)
  • Small freezer: 550 (Starting Watts), 350 (Running Watts)
  • Blender: 500 to 850 Watts / 650 (Starting Watts), 250 (Running Watts)
  • Light bulb: 13 to 100 Watts / 6 bulbs:  350 (Running and Starting Watts)

Toaster:  250 Watts (Starting and Running Watts)

  • Fan: 11 to 165 Watts
  • Microwave: 750 to 1100 Watts
  • Coffee maker: 850 to 1200 Watts

We recommend that you buy a generator that supports between 4000 to 7000 watts.  As a food truck owner, you should take into consideration the age of your appliances.  An old fridge will draw more watts.


  • We recommend that you use a licensed electrician to meet all the local codes when you install your new generator. Never connect the generator directly to your kitchen appliances; you will need a transfer switch installed.
  • Make sure your generator is properly grounded to prevent electric shock. You can use a ground fault circuit interrupter.
  • You will need to inspect the generator regularly. It is crucial not never to overload the generator, and remember to turn off all appliances in the Food Truck before turning off the generator.
  • Another safety recommendation is always to turn off the unit and let your generator cool down before refueling.

Fuel Efficiency & Running Cost:

  • Running costs of the generator is something you must consider. Food truck generators run using diesel, gas or they may be solar-powered.  Others may run on two types of energy, for example, gas and solar power.  Generators that use between 4000 and 7000 watts use approximately 5 to 7 gallons of gasoline fuel.  Gasoline is cheaper than diesel, and running the generator will be more affordable if solar is combined.
  • A food truck generator usually runs for between 7 and 10 hours at one time. On average, a food truck generator will consume about 1 to 2 gallons of fuel per hour.

Price Range:

The price range of generators, which support a food truck that draws a minimum of 4000 watts and a maximum of 7000 watts, is between $350 to $1000.

What Size Generator would I need for a Food Truck?

  • When buying a generator for your food truck, you need to consider the generator size and how much electricity is required to power all the necessary appliances.
  • No matter you use your food truck at festivals, events, or just for catering, or they are situated in one designated place or used at different venues, you still cannot rely on the venue host to supply electricity. So every food truck owner needs to have a good-sized generator.
  • It is generally a good idea to buy a generator, which has more power than all your appliances combined; this will ensure that the unit will cope with the daily operation of the food truck.
  • Another point to consider is the type of load every electric appliance uses. For example, A refrigerator uses a reactive load.  This means that the current is not in phase with the voltage, resulting in a higher power needed to start the appliance when turning on the electricity.  Other appliances which use reactive load are air conditioners, freezers, fans, and pumps.
  • The size of the generator is an essential factor to consider. How much electricity is needed must be accurately calculated so that the food truck owner has sufficient energy to operate.  Other factors need consideration:  its safety, portability, how quietly it runs, fuel efficiency, and price range.


1. How do I set up the generator to power my food truck?

Firstly, if your generator is new, you will need to look in your service manual and run your generator in.  Once run-in, you will not fill it with fresh oil before using it.

Secondly, you will need to plug your electrical cable from your generator into your food truck plug outlet.  This cannot be done the wrong way as both sides have different types of plug fittings.

Thirdly, turn on the fuel and start the generator using the electric start or pull start.

NB:  When installing electrical boxes in your food truck, it is advisable to contact a certified electrician to do the job.

2. How far should I place my generator from my food truck?

Always install your generator 20 feet away from doors or windows, and never install it in your food truck.  This is because it emits poisonous gases when running.

3. How to reduce the noise created by Portable Generators?

Position your generator away from people and other food trucks.  If the ground is soft, this will help to reduce the noise.  You can also use four plywood  sheets of and a non-flammable material sheet, for example, drywall since it’s fire-resistance. Every piece must be around four feet wide and three feet tall.

Place the drywall on that side of your generator where the exhaust is located. Prop each piece of plywood, at an angle, around the generator. Placing the plywood at an angle, there will be room for airflow while deflecting sound waves into the world.
