Things to Consider

In this section, we will cover everything you need to know to make sure you get the best generator for a food truck to serve your customers. We also took the time to answer some FAQ that you might have as well.

How much power do you need for a food truck?

БезымянныйThe amount of power that you are going to need to successfully run your food truck off of a generator is going to come down to how much equipment you intend to run off of it. It is always a better idea to have too much power production potential than not enough. Every generator on the market’s output is measured in watts, which is the measure of potential power that it can produce. The unfortunate thing is that most appliances such as grills, griddles, and freezers/fridges, do not tell you their wattage requirements. Instead, they will only tell you the voltage, which is the electrical energy, and the amps, or the electrical current that the appliance requires.

Thankfully, the wattage is pretty easy to figure out. All you need to do is take the voltage and multiply it by the amps, and you will have the wattage. For instance, if a refrigerator is plugged into a 120V outlet and requires 10 amps of current, then these two figures need to be multiplied. This will give you the wattage of your fridge, which is 1200 watts.

Once you have calculated the wattage of everything you want to run off of your generator, then you will have a better understanding of how much power output you need.

It is always a good idea to get more than you need, since then you can rest assured that you are covered even if you decide to add more appliances later on.

Generator features to consider before making a purchase

As you can imagine, there are several important factors that you need to consider to make sure you have the best generator for a food truck. In this section, we will go through everything you need to take into account to get the model that will best fit your needs.

Generac_Outage_Kit_2What fuel options to prefer: gasoline, propane, or both?

When it comes to a fuel source for your generator, you have several different options to choose from. You can select a generator that runs on gasoline, propane or one that has the ability to run on both. Gasoline is a bit more expensive to utilize, but it has the ability to give you more power than propane. On the other hand, propane is cheaper to use but won’t give you as much power.

There are models that give you the ability to use both fuel types, such as the DuroMax XP12000EH, actually the best one among Duromax generators. These hybrid models allow you to select the fuel you use based on your power needs, which is a good way to make sure you have enough power when you need it but also allows you to save money when you don’t need as much power.

Reliable and powerful engine

In order to create the amount of power that a food truck requires, you are going to need a pretty powerful engine. The power that an engine can put out depends highly on how quickly and how far the pistons can move within an engine. This is expressed in cc. The higher the number of cc in an engine, the faster the pistons can move, and the further they can go in each cycle, which in turn creates more power.

The higher the cc of an engine, the more fuel it is going to require. Larger engines are also much louder than small engines.

No matter how powerful an engine is on a generator, you want to make sure that it is easy to start. The last thing you want to have to deal with is hard to start the engine when you are trying to cook your food for your customers, considering this, it is advisable also to look at the NorthStar models which mostly have the electric start and are powerful enough for a food truck or at A-iPower models.

Runtime and fuel tank capacity

The fuel tank capacity of your generator, along with the fuel type you select, is going to determine how long the generator is able to run. The larger the tank, the longer you will be able to run your machine. You should carefully consider how long you will need your generator to run so that you can be sure to get the model that will keep going as long as you need it.

Outlets and powering options

6 Most Efficient Generators for a Food Truck – Power Your Business

When it comes to the number of outlets and the different types of outlets on a generator, more is definitely better. You need to be certain to get a generator that comes with enough outlets for all of your equipment. You will also need to be sure that the outlets are the proper voltage for your gear, or you won’t be able to utilize them at all. USB plugs are also a big plus, since more and more electronics are beginning to use them.


Noise level is always measured in dB or decibels.  The higher the amount of dB that a generator puts out, the louder it is going to be. Since you are going to be running your generator right next door to your food trailer, you certainly don’t want anything that is terribly loud. The highest noise level that would be appropriate for a food truck would be 76 dB. Anything louder is sure to annoy your customers. The quietest model available is the Westinghouse iGen4500DF, which only puts out 52 dB, and that is one of the reasons why it is considered to be one of the best Westinghouse generators.

Size, weight, and portability

Generally speaking, the more powerful a generator is, the bigger and heavier it is going to be. If your food truck is cramped, then you won’t be able to fit a larger generator, so make sure you measure your space carefully. The size and weight of the generator shouldn’t be all that big of a deal when it comes to portability, since all of the models in our listing have wheels and a handle to easily put the generator into place.

Commercial warranty

Since you are going to be using this generator for a commercial purpose, you need to read the warranty information very carefully, as some warranties last longer for residential users in comparison to commercial uses. The Honda EU7000iS is one of the only models with a warranty that is the same for both commercial and residential users.

Tips and Tricks

p_83bc342e-2115-4cf5-9a60-875b42366adc_1200x1200When it comes to taking care of your generator, it is important to think of its maintenance in the same way that you think of a car’s engine. You should regularly change the oil to make sure that all of the parts are properly lubricated so that they don’t break down.

Though you might think that installing a generator into your food truck is a simple thing to do, it is probably a good idea to get it done professionally. That way, you can rest assured that it was done properly and that all of the components work correctly.

Something else that you need to keep in mind is that generators are not weatherproof. If the weather seems like it is going to be rainy, you will need to keep your generator covered in such a way that the generator won’t get wet, but will still allow the exhaust to go out properly.


When it comes to getting the best generator for a food truck, you are going to get what you pay for. The more you pay for your generator, the better it is going to be, and the better it will work for you. If you want more outlets, more power, better fuel efficiency, or longer run time, then you are going to have to pay more for it. Another big factor in the price of any generator is the type of generator it is. There are two distinct types of generators. You can either select a standard or inverter generator.

Inverter generators are usually more fuel efficient, quieter, and more portable than a standard style generator. They are also much more expensive, so this is something you will want to keep in mind before you make your final determination. While they will cost a lot more up front, an inverter style generator, like the Honda EU7000iS, might be well worth it.


Both gasoline and propane are good fuel choices for a generator, though they do differ in what they can offer as far as the performance of your generator is concerned. While gasoline is able to produce a larger power output, propane is generally more fuel efficient. This efficiency helps to make propane a much more budget-friendly option than gasoline.

The dB range for food truck generators is relatively wide. The quietest models, such as the Westinghouse iGen4500DF, operate in the 50 dB range. Larger and more powerful models, like the DuroMax XP12000EH, put out a little more than 70 dB. All other models fall somewhere in between these two levels.

You have two options when it comes to transporting your generator. You can either store it inside of your food trail during transportation, or you can get a small trailer to pull it behind. Obviously, putting it inside your vehicle is the most convenient route, but you might not have enough space to fit it easily. You will then need to get a small trailer to tow it behind your vehicle. If that is the case, be sure to check to see if your vehicle has all the necessary components to hook up a trailer safely.

The oil that you use in your generator will depend on the weather. If it is above 32 degrees, then you can use SAE 30. If the temperature is below freezing, however, then you will need to use 10W-30. You could also just use Synthetic 5W-30, as this can be used at all temperatures. No matter what oil you decide to use, you will need to change it after every 100 hours of operation to keep your generator running smoothly.


Our choice for the very best generator for a food truck has got to be the Honda EU7000is. This inverter style generator is extremely fuel efficient and has an outstandingly quiet operation. It is also powerful enough for use with multiple large appliances, making it ideal for large or small food trailers.

One of the best ways to guarantee that you will be able to operate your generator all day long, regardless of how many customers you have, is to get one with a large tank. The Honda EB10000 has a huge tank, giving it a very long run time, which is perfect for a busy day of cooking.

If you are going to be moving your food trailer around to multiple locations, then you will want to get a highly portable model that is easy to move around. The Generac GP6500 is compact, has oversized wheels, and a strong handlebar, which makes it very easy to move into position.
