Depending on the model, generator prices can vary dramatically. The Green-Power America GPD5000W offers starting watts for a much lower cost than other models. Despite only getting 3,850 running watts, most home devices should be able to be powered.

With this cheaper model, you don’t get 240V connectivity; however, you do get 12V and 120V outlets, including a 120V twist-lock outlet. At 109 pounds, this machine weighs significantly less than several of its competitors, even though it is a bit larger at 26″ x 24″ x 22″. You’ll find 2 fold-down handles that make it easy to pull wherever you need it.

WEN 56475 Portable Generator - Best 5000 Watt Generator
All 50 states are CARB and EPA compliant
With keyless entry and start
Work at low oil
Via automatic voltage regulation

With 3,750 running watts and 4,750 starting watts, the WEN 56475 portable generator is affordable but a little underpowered. The majority of your appliances will still work, except for those that require 240V electricity. At half load, this machine offers only 10 hours of runtime, despite its lower power output.

Even so, there’s plenty to enjoy here. WEN 56475 Portable Generator meets CARB and EPA compliance in all 50 states, including California. With its keyless, electric push-button start that gets it going quickly, it’s easier to start than many models.

As for connectivity, you’ll find 2 standard 120V outlets, a twist-lock 120V outlet, as well as a 30-amp RV outlet. By regulating voltage automatically, your devices are protected against voltage spikes, and by shutting down when the oil level is low, your generator won’t run.

9. DuroMax XP5500EH Fuel Portable Generator – Best 5000 Watt Generator for RV

DuroMax XP5500EH Fuel Portable Generator - Best 5000 Watt Generator
Hybrid design using dual fuels
With 69 decibels of operating noise
Simultaneously operates on 120V and 240V
Small dimensions

Powered by either propane or gasoline, the DuroMax XP5500EH is dual-fuel capable. The propane hose is not included, and switching between fuel sources is more complicated with this machine than with others. Although it’s a nice feature to have when you need it.

A 120V and 240V outlet can be used simultaneously on this machine. There is no 30-amp RV outlet, which seems like a major oversight since RVs often use generators like this for power when boondocking. In comparison to other models, this generator only makes 69 decibels of noise when running.

The DuroMax XP5500EH Fuel Portable Generator at 127 pounds, the machine is a hefty one, though it is far from the heaviest. Although it is fairly compact, the dimensions are 24 inches by 17 inches by 17 inches. The fuel tank holds just under four gallons and provides a starting power of 5,500 watts and a running power of 4,500 watts.


12 hours of use
With 6250 starting watts and 5000 running watts
Up to 50% quieter than competitors
Safe for sensitive electronics

Running volume of 69 decibels
Includes 12V, 120V, and 240V outlets
Gas or propane dual-fuel design
Receptacles are covered

It is one of the quieter generators we tested, with an operating volume of 69 decibels. Despite only having two 120V outlets, it offers decent connectivity with 12V, 120V, and 240V outlets. 

The Durostar DS5500EH has a starting power of 5,500 watts and a running power of 4,500 watts, but it’s quite a bit bulkier than similar machines we’ve seen. It measures 25″ by 22″ by 22″, making it substantially wider and taller than comparable models.

A nice feature is that this generator runs on either gas or propane. You will have to source a propane hose separately since the propane hose is not included. This machine has an electric “rocker start,” but the battery died after a few months, rendering it essentially useless.


120V and 240V outlets are available
There are four 120V outlets
Rated at 6,875 watts


The 5,000W generator has a larger footprint than other 5,000W generators
It has only two 120V outlets

Buyer’s Guide

It can be difficult to narrow down all the choices and be sure that you are choosing the best generator unless you have spent hours comparing the specifications of similar generators. This buyer’s guide is perfect for you if you’re still on the fence about which model to choose.

Choose for the Right Generator

While all of these machines have the same general purpose of powering appliances and electronics when there is no electricity, the differences between them make each one more or less suited to different situations. The last thing you want is to purchase a generator for a specific need, only to find that it won’t work as you expected.

In order to prevent this from happening, we’ll discuss the most important factors to consider when purchasing a 5,000-watt generator. Then, find the machine that most closely matches the parameters that are most important for your specific needs.

Starting Watts vs Watts Running

A generator’s power output is measured in watts. The motors on different generators may be different sizes and offer different levels of horsepower, but the important measurement is watts, as this is what you will be able to power.

Models are named according to their running watts, while others are named according to their peak wattage. These measurements may sound similar, but they’re quite different.

A generator’s peak wattage or starting wattage is the maximum power it can generate for a short period of time. They can’t maintain this level of output for long, but they can spike it for a short time. Appliances, power tools, and other electronics often require double the amount of power to get started than to run.

Because of this, a generator’s running wattage is smaller. A generator’s running watts are its maximum power output over a long period of time. You will mainly rely on this number. However, if you do not have enough starting watts to run a large device, the running watts you do have won’t make much difference.

What is Versatility?

Generators serve as backup devices in the event of the loss of electricity. They can therefore be used in many different ways. For example, they can be run on a variety of fuels. What if there is no gas available? Is it possible that the few gallons kept on hand will not last long enough if the power is out for longer than expected?

Several generators solve this problem by allowing the use of multiple fuels. In most cases, this means they run on gas or liquid propane, which most people already have on hand. You can pick it up at many local gas stations, hardware stores, and even grocery stores if you don’t have it.

In fact, some of our favorite dual-fuel generators even allow seamless switching between fuel sources, so you don’t even have to turn off the machine.

When you run a dual-fuel machine on propane, however, you may find that it offers lower power.

Size and Weight of Generator

You might not consider the weight and size of your generator if it will be used as a backup for your home. You will prioritize these traits more if the generator is used for a construction crew or if it is carried around by your RV.

Even among generators of similar power, there are some major size differences. Despite having a relatively similar power output, some models are several inches larger in each direction and can weigh nearly twice as much as others.

Look for a more compact and lightweight option if size and weight are important to you.

Fuel Efficiency Details

Even if you have several gallons of fuel stored away, do you know how long an emergency will last? In addition, if you use a generator to power a job site, then fuel economy can significantly reduce your overall operating costs.

Fuel efficiency is measured in runtime hours. You should also consider tank capacity. Running a 4-gallon generator for 12 hours is great, but it’s not the same if you’re running a 7-gallon generator for 12 hours.


It is possible to buy a 5,000-watt generator for a good price. Sadly, that’s what makes it so hard to decide which one to buy! Fortunately, we have been able to test them side by side for a fair comparison. As we’ve discussed each of these models in our reviews, we’ll quickly summarize our recommendations once again to keep them fresh in your mind.

Our favorite overall was the Pulsar PG5250B. Due to its Switch & Go Fuel technology, you can switch between gas and propane as fuel sources without shutting down the machine, and a propane hose is included.

In case of an emergency, the Green-Power America GPD5000W provides 12V and 120V outlets at a very affordable price. It weighs only 109 pounds, making it much lighter than competing models, yet it offers 11 hours of runtime on four gallons of gas.

Are you in need of more power? The Generac 5939 portable generator offers 6875 starting watts and a robust 389cc engine. As well as 120V and 240V covered receptacles, you’ll get folding handles and wheels that never flatten.
