How to choose the best generator for a food truck (buying guide)

best generator for food truck

Having all the best models in hand doesn’t mean you can pick any out of the list. Some criteria matter your shopping decision.

Let’s take a look at what to need to buy the right generator for your truck.

Type of fuel source

While most generators accept only gasoline, modern generators can operate on a duel-fuel engine.

For food trucks, gasoline-powered and duel-fuel generators are better options because you can refill the tank with gas when you do that for the truck’s tank. Besides, gasoline produces greater wattage than propane.

But not all the goods come to gasoline. This fuel source is more expensive but longer in runtime.

On the other hand, propane can be refilled without having to cool down the generator. It is also possible to hook up with a second propane tank to take up the place when the first tank is exhausted. That guarantees you no downtime to your power supply.


You don’t want to keep refilling the generator once in a few hours, do you?

That is why runtime is significant for a food truck.

A long-running generator saves you a lot of time taking care of your customers instead of running back and forth to refill the tank

That said, gasoline-powered machines are not optimal because their fuel reservoirs are limited in size.

But the fuel efficiency also matters when it comes to runtime. More fuel-efficient engines boast the engine’s longevity for the same amount of fuel.


Working on a food truck, you will have to move the generator outside when operating. It’s easy to understand why you need a portable generator.

Size is a factor that impacts a generator’s portability. It will be difficult to move a big unit around alone. Also, you want to make sure it fits your trailer.

Many generators come with handles and wheels to leverage its weight. And if you are serious of portability, you should seek machines feature heavy-duty carry housing.


Don’t skip this last factor because you will need it in the long run since your generator is a business investment.

Honda, Champion, and Wen are manufacturers that provide a 3-year warranty to most of their products. It can be more expensive, but you will see how useful long-warranty is as you put the machine to daily use.

Who makes the best generator for a food truck?

best generator brands


Champion defines their brand to be a market leader in power generation equipment. Products of Champion are not only high in efficiency but also superior and innovative in quality and design.


Established since 1846, Westinghouse envisaged being a top-lined producer of smart appliances for energy solutions. Up to now, their modest power items have utilized the newest technology and received tons of warm feedback from consumers.


The representative of Asia has made its step in the energy industry since 1952 with milestones of product lines. Although well-known in the automobile industry, Honda has been successful in applying their engines for generators which are no less competitive than any global brand.


Do food trucks need generators?

A: Such appliances like refrigerator, air conditioner, oven loaded on a food truck, need the power to operate. But you cannot supply them electricity with the tiny engine of the truck. That is why food trailers definitely need generators.

How many Generators do I need for a Food Truck?

A: The size of the food truck may not matter, but the setup scale of it: the more appliances you need to run, the more powerful the generator you need. In many cases, your trailer may require more than one generator to compensate your business’s high demand.

In particular, if you food truck makes use of well water, you’re going to need power to operate the pumper. It requires wattage from 3,800 units.

A food trailer with more than one appliance to run may go with a 10,000W generator. It should power up 5 light bulbs of 70W, an electric stove, one refrigerator, a microwave, a toaster, a washing machine, and most of the basic items in your kitchen.

But keep in mind that as many as electric stuff on the run, they will consume the material faster. So, consider turning off those appliances that you don’t need.

Can you put Gas in a Generator while it’s Running?

A: NEVER. Because it’s dangerous to refuel an engine that is heating.

We already mentioned that gasoline generators should be turned off and cooled down before it can receive more power source. Living with now power for 15 minutes won’t kill anyone, but a gas fire or explosion certainly could.

How Do I Ground My Generator?

A: When you connect an electrical circuit to a reference ground, it means grounding.

In this case, you will need to connect the frame of the generator to a grounding rod.

This connection from your generator’s frame to the grounding rod grounds will make the generator operate more safely.

What you need:

  • Wire strippers
  • Copper ground wire
  • Copper grounding rod, 4 foot
  • Hammer
  • Wrench
  • Pliers

Step 1: Drive the copper ground rod into the ground using a hammer at 8 feet for a proper ground for the least.

Step 2: Use pliers to strip the copper wire and wrap it around the copper ground rod.

Step 3: Loosen a grounding bolt on your generator to wrap the stripped wire around it. Then, tighten down the wire stripe.

Wrapping up

Isn’t it great to see your mobile kitchen running on properly?

A generator is a worthwhile investment than anything. Not only you can use it  your food trailer but also anywhere that needs power.

Out of the suggestions above, we reckon the Champion 7500 Duel Portable Generator fits most of the demand for a nice-looking, powerful, extended warranty, and portable generator. It may cost you a bit more, but with every penny you spent, you get it right back and more in every use for your food vehicle.
