Best Generators for Food Truck | 6 Powerful Units Reviewed

Having a food truck is a great way of taking your food products on the road wherever you go.

You can prepare, cook and serve food in a quick, easy and portable way. Running a food truck can also take up a lot of electrical power, as you will need some form of electricity to keep your mini kitchen running. 

For those times when you need access to electricity, you will need a generator. In this sense, you will need a generator that can withstand all of your cooking necessities, whilst also being portable enough to take on the road with you. 

One of the main attractions of having a food truck is that you can serve food anywhere. That means that there may not necessarily be an outlet or means of connecting your truck to gain power and electricity.

If this is the case, then you will not be able to power your food truck’s refrigerator, stove, microwave, coffee machine, air conditioner or any other appliances. 

Having a generator for your food truck is therefore, in most cases, an absolute necessity. However, with the limited space inside your truck, you will need a great, powerful generator that is small and portable enough to be moved around.

Most food trucks need a generator from around 4000-7000 watts depending on the number of appliances and wattage used. These generators will need long lasting power to help food trucks run all day efficiently, and be compact enough to be packed away at the end of the day.

To help you run your business smoothly, we have compiled a list of the best generators for food trucks. This way you can power all of your appliances with ease, and you can get back to focusing on your successful food truck business.

Best Generators for Food Trucks Buying Guide

How to Find the Best Generator for Your Food Truck

You may find that looking for a generator for your food truck is a trying task. You will need one that is powerful and long lasting enough to cover your electricity all day while serving up some delicious food. 

However, the nature of the food truck is that it is portable and able to go anywhere for your customer’s convenience. These are qualities that must be prevalent in your generator too. 

You will need it to be powerful, yet portable and not too large that it takes up lots of space, when your food truck is already cramped enough. You will need to gauge where you can keep your generator for storage, and where it can be placed for use in the day. 


Similarly, you should consider how heavy the generator will be, especially if you work on your truck by yourself, or have no help to carry it in and out of the truck.


You will also need to consider how much power you will need to run your food truck business.

You will have to measure your desired wattage, from all of your electrical appliances that you use to serve food and beverages. Once you have measured the wattage, you must combine this number to find your overall power requirements. 

You should also try to get a generator that can withstand a little more than your total wattage measurements so that you know that it will not overheat or fuse out.

It is also important to remember that the closer your power draw is to the maximum outage of the generator, the more fuel you will use. 


Most modern generators will run on either propane or gasoline, so you should think about which type of fuel you would prefer your generator to use.

Gasoline produces a greater wattage and is much easier to refuel should you run out.

On the other hand, it  can be more expensive, and propene can be easily stored in your truck. 

Noise Level

One of the disadvantages of using a generator is that it produces a lot of noise when in use.

You may benefit from purchasing a generator for your truck that does not have excessive noise levels as it may ward off or irritate potential customers.


When purchasing a generator for your food truck, you should consider its runtime.

A generator that can run for long periods of time without running out of fuel will be highly beneficial for those busy and long days serving food to your customers. 

Conventional or Inverter Generator

You can use either an inverter or a conventional generator for powering your food truck, however it will depend on what you need it for.

If you would prefer a powerful generator that will run many appliances at once with ease, then pick a big conventional generator. 

On the other hand, if you would prefer a smaller unit with less operational noise, then an inverter generator may be best for you.
