How Much Gas Does A 5000 Watt Generator Use?

For the sake of convenience, most portable generators will run on gasoline. In one day / 24 hours, a good 5,000-watt generator will use approximately 18 gallons of gas. When used for an extended period, this makes it incredibly unrealistic and costly. There are a variety of effective gas generators that can be utilized at home. A 1-2 gallon gasoline tank may often last 8 to 10 hours. As a result, long-term use is both impracticable and costly.

How long will a 5000-watt generator run?

On 18 gallons of gas, a portable generator with 5,000 watts of power can run for around 24 hours. This is not the most cost-effective or long-term solution.

How Much Does A 5000 Watt Generator Cost?

Generators exist in a variety of styles, sizes, and pricing points. The most expensive 5,000-watt generators can cost up to $3,000 for a model from a reputable and well-known manufacturer. The budget model on our list of the seven best 5kW generators is available for as little as $400.

How Much Does A 5000 Watt Generator Cost

Peak Watts Vs Running Watts

If you possess a generator, you’ll need startup wattage to get it going. Most units provide this power very briefly, hence the terms ‘peak watts’ or ‘surge watts.’ The power current begins to flow when the electric motor is turned on.

The magnetic fields then attract each other, causing the motor to turn. The current decreases as the speed increases thus allowing the motor to attain full speed. The current is approximately 5 times higher during the short startup period than when the motor is running at full speed.

A circuit breaker prevents power overload as the current grows. The generator could catch fire if it didn’t have it.

Nonetheless, it allows higher quantities of current to flow in a shorter period. The circuit breaker will trip if the current continues too high.

Peak watts

This is the wattage required to power the generator for a few seconds before it reaches full power. The starter watts ensure that the motor spins at the correct RPM and provide the most accurate estimate. If the initial wattage is too high, the generator may overwork or stall due to electrical overload.

Running watts

This is the amount of power required to keep the refrigerator running. It specifies the number of appliances that a generator can power. This wattage will be provided continually by your generator.

Best 5000 Watt Portable Generator – Buyer’s Guide

Fuel Options

All generators are typically powered by either gasoline or diesel. Petrol-powered generators are the more popular of the two options on the market today since they are less expensive and have more design options than diesel engines.

Diesel-powered generators, on the other hand, offer their own set of advantages and disadvantages. They are more fuel-efficient than their competitors and are typically used to power larger equipment or locations.

Both accessible solutions have their own set of strengths. Just make sure to select the one that best meets your needs.

Engine and Power Output

When it comes to power production, you only need to know two things about a generator: starting watts and running watts. During startup, generators often consume up to 2-3x the running wattage. So, if your heater requires 1500W to run, it will need 3000-3500W to start up. Before purchasing a portable generator, consider both types of wattage.

Power Outlets

Before purchasing a generator, establish what type of outlets you will require. Smaller generators typically include two 120V (AC) outlets and two or three USB connectors. Larger wattage generators (beginning at 4000) will feature 240V plugs and more than 120V outlets.

Before purchasing a generator, establish what type of outlets you will require. Smaller generators typically include two 120V (AC) outlets and two or three USB connectors. Larger wattage generators (beginning at 4000) will feature 240V plugs and more than 120V outlets.

Check to see if the outlets offer GFCI protection before deciding on a specific type. This will protect your safety and the safety of other electronic items in your home.

Fuel Tank Size and Runtime

It is not a surprise that a generator with a larger fuel tank will run for a longer period. Most generators today have tanks that will provide at least 7-9 hours of service at 50% load. If you don’t use a larger amount of the available power, the runtime can even be prolonged.

A large fuel tank may be beneficial, but keep in mind that it will reduce the generator’s portability. A generator with a larger tank is typically heavier and less portable. So, determine the tank size you require for your generator based on these facts.

Best 5000 Watt Portable Generator – Buyer’s Guide

Operational Sound

There are many generators on the market with incredibly low noise levels. However, all of them will fall short in the game of watts. When running, all generators with wattages of more than 4000 generate audible noise. Another thing to keep in mind when it comes to noise is that diesel-powered generators are noisier than gasoline-powered generators.


If you enjoy pulling recoil cords to start engines, avoid buying ones with an electronic start. This will save you some money. The starting method does not affect the device’s performance; rather, it is a matter of personal preference.

Whatever you choose, make sure to charge the battery before using it. Lithium-ion batteries are used in modern generators. As a result, leaving the generator plugged in between uses should not be an issue.

Paralleling Capabilities

Paralleling is just connecting two generators of the same size and (in most instances) brand to increase power by doubling. By connecting two generators in parallel, you may combine the wattage of the two units and get more wattage into your electronic equipment. All you need is a parallel cable to connect two generators.

This unique function, however, is not available on all generators. Models with paralleling capability will be more expensive than usual. Remember that you’ll need another device identical to yours to even test this function. So, before you spend the extra money, consider whether you truly need paralleling features in your generator.


Modern generators include a variety of safety mechanisms that safeguard both you and the device. When shopping for a portable generator, look for the following features:

  • CO Shutoff

When referring to this feature, manufacturers may use words such as “CO Guard” or “CO Protect.” This function, whatever it’s called, employs CO sensors to detect the level of Carbon Monoxide and quickly shuts off the device if the amount of the gas exceeds a specified level. Instead of succumbing to marketing tactics, check to see if the device you’re considering purchasing has ANSI/UL2201 certifications for assurance.

  • Low-Fuel Shutoff

If the oil level in the tank goes below a certain level, this feature shuts down the generator. Even though this is a more frequent characteristic than the previous one, you should still examine it before purchasing a certain device.


You’d undoubtedly want your generator to run smoothly for many years to come. Choose units with a guarantee that meets your needs. Most manufacturers provide at least 2-4 years of warranty on their equipment.
