The Westinghouse WGen9500 is our number one pick on this roundup – for several reasons. It comes with several impressive features and combines cost, design and performance to give one of the best 50 Amp generators that you can spend money on right now.

It is a dual-powered generator that can run on either gasoline or propane. From our testing, it starts on gasoline and switches to propane during use. The ability to switch fuel means that it runs for a longer time than your typical generator. In addition to the runtime delivered because of the generator’s ability to switch fuel, there is also a 6.6 gallon tank. This tank gives you plenty of power and fuel that extends the generator’s runtime to up to 12 hours at a go.

The design of the unit will ensure that it lasts for a long time. All the parts are made from high-quality materials and the frame is made of steel. Therefore, the Westinghouse WGen9500 will survive rough use without sustaining damage. Additionally, the steel frame has large wheels with excellent traction. Generators usually generate a lot of noise, and noise is to be expected from this model. However, the addition of rubber brushings on the front will absorb vibration and help to reduce the noise production.

Under the hood, there is a powerful 457cc 4-stroke motor that will deliver powerful energy output.

Starting the generator is a breeze since you have an electric start and a key fob. Therefore, you can start it in either way.

Power delivery is one of the best things about this model. It comes with a peak wattage of 12,500 watts when it runs in gasoline. When it runs propane, the power output dips to 11,200 watts. Either way, it offers some serious overall power. Due to this ability, it will help to power most of the appliances in your home in cases of blackout.

Outlets are also excellent on this model. It is fitted with a pair of GFCI 120V 5-20R standard outlets, a pair of 5V USB ports, and a handy transfer switch. Therefore, there are enough outlets to power your RV or home. For the best runtime and durability, all the outlets have a rubber cover. This will prevent any issues from water damage and make everything safer to use. There is an automatic shutdown feature too that will switch off the generator whenever it approaches low oil levels.

Starting the generator is pretty easy, but using it is made even easier because of the intuitive control panel. This panel includes the VFT Data CENTER Program. Because of this panel, you will get important reminders and updates as soon as they are required. Therefore, you can notice if there are any maintenance steps to be taken before these become big issues.

The Westinghouse WGen9500 offers you lovely design, a 3-year warranty and powerful performance that you will certainly love.

Why is it special? The Westinghouse WGen9500 comes with high power output that will power most of your devices. It offers plenty of safety features as well. The large tank capacity and dual-fuel usage also makes for an impressive generator.

It is built out of high quality, durable parts. These will ensure that the vibration doesn’t adversely affect the parts of the generator. This model is also heavy, just like our number choice. However, the manufacturer has provided large tires that will help you to move it. If you are using it for your RV or on a job site, this portability surely comes in handy.

Despite the presence of wheels, though, it should be noted that it still remains a heavy unit. It weighs 260 pounds, which, means it’s not something you just move at a moments’ notice.

Aside from the heavy weight, there are several benefits of using this model. For one, it is pretty easy to use. There is a control panel that has all the instruction legible and easy to read. Therefore, you can use it with ease whether in the home or for work.

Just as our top pick, this model comes with some safety features. For example, it offers you a low-oil shut off mechanism that will turn off the engine when the oil reaches dangerous levels. This will prevent damage and make it work for a longer time.

What makes it stand out? The DuroMax XP12000EH comes with a durable, all-metal build that ensures that you will use it for a long time. It also comes with safety features that will ensure longer use. The powerful motor produces enough power to carry your appliances

Which disadvantages must you keep in mind? Just like the Westinghouse, the DuroMax XP12000EH is heavy. We also noticed that the support from the manufacturer is rather limited.

  • Noise level: 76 dB
  • Warranty: 1-year limited
  • Dimensions: 28.5 x 21 x 22 inches
  • Weight: 209 lbs

Buying a 50 Amp generator can be an expensive endeavor. There are several models on the market that are rather expensive and will cost a pretty penny. If you are looking for a low-cost model, though, then you’ll certainly enjoy the Pulsar G12KBN. This generator is a 50 Amp generator with plenty of impressive benefits that still manages to come at a relatively low price.

Just like the two units that we have reviewed above, this budget option comes with dual-fuel technology. Therefore, it gives you excellent versatility and power. It starts on gasoline, and with this fuel, it will give an output of 9500 watts and a peak wattage of 12000 watts. This certainly will handle your pressing needs. When you switch to propane, the generator has a rated wattage of 8550 watts and peak wattage of 10800 watts. Therefore, whether you run it on propane or gasoline, you have enough power for most of your requirements. Additionally, it is a dual-fuel unit. That means that it works on either gasoline or propane. The gasoline is an excellent fuel because it helps you to start the generator even when the weather is pretty cold. Propane might not give you the ability to start in the winter, but since it burns slower, it improves the runtime of the generator. In other words, the gasoline starts the generator while the propane will keep it running. Therefore, it offers more economical performance and will increase the runtime

In spite of the plenty power, it has a relatively quiet performance. During our testing, we registered a noise level of 76 decibels. While this is still loud, it offers good performance in general.  Switching it on is quite a breeze as well since you can use an electric starter or a pull-start mechanism.

Runtime is an important consideration when choosing a generator. Thankfully, the 8 gallon tank capacity gives enough fuel to give an runtime of about 12 hours at half load. However, if you run on propane, it will work for about five hours.

Outlets are awesome here because you have quite a lot of them. You will find a DC outlet , an L14-30R receptacle, and more.

Although this is reportedly portable, the portability is in relation to the others that we have reviewed so far. Although it is lighter than the others we have considered, the 209 pound weight is still heavy. Fortunately, the wheel kit comes in really handy and makes it easier to move the generator around.

Away from the dimensions, the Pulsar G12KBN has other nice features that make it easier to use and maintain. The control panel is conveniently placed and will show the important parameters. These parameters range from the voltage to the frequency and runtime. Although there isn’t an auto-shutoff feature, there is a light indicator to show when the oil levels are dangerously low.

The Pulsar G12KBN is CARB-compliant and has a spark arrestor. These features make it safe to use and friendly on the environment.

Why is it special? Overall, the Pulsar G12KBN is designed for home owners that want a portable and powerful generator as a backup in times of power outages. It comes with plenty of useful outlets, delivers a more than decent amount of power and runtime.

What are the flaws? It is a loud unit which is a bummer. It also lacks a remote start features

DuroMax XP10000E Best 10,000-Watt Generator

  • Type: conventional
  • Starting system: electric
  • Peaked/rated watts: 10000/8000
  • Engine: 439cc DuroMax OHV 4-stroke
  • Fuel type: gasoline
  • Fuel tank: 8.3 gal
  • Runtime: 10.4 hours (50%)
  • Outlets: (2) 120V GFCI, (1) 120V 30A, (1) 240V 30A, (1) 240V 50A
  • Noise level: 72 dB
  • Warranty: 3-year limited (residential), 1-year (commercial)
  • Dimensions: 30 x 29 x 26 inches
  • Weight: 218 lbs

The DuroMax XP10000E Gas Powered Portable Generator is not the cheapest model out there, but if you need something to reliably give you a huge level of power and heavy loads then it could be the ideal model for you. A lot of people are using this sort of generator for things like power outages in their home, and the 439cc OHV DuroMax Engine means that it can handle really demanding home appliances including things like air conditioners.

Much of the power comes from the MX2 technology which gives two 120-volt receptacles, so it is a bit like running generators in parallel. You can run at both 120 V and 240 at the same time, or just use one 120 V output with full power.

The generator is EPA and CARB approved for use in all 50 of the United States. So, you can rest assured that this is built with plenty of quality.

The generator can run at 8000 watts continuous, and at about 50% capacity you should expect to get 10.4 hours of run time out of a tank, which is pretty impressive. The peak of 10,000 watts is almost up there with the most powerful models on this list. Even if you are having to run the power for the whole house, you can rest assured that it isn’t going to give up on you in a hurry or leave you having to refill all the time.

Sturdy and sizable wheels make it relatively easy to transport, but at over 200 lb you do need a bit of strength to take it long distances, or if you need to take it in a vehicle, for instance. It has the capacity for over 8 gallons of fuel, so it makes sense that this is hardly as light as a feather.

There’s a one-year warranty for commercial users, which may be a little frustrating when you realise that the warranty is three times that amount for those who are using the generator in a residential setting.

What makes it stand out?

  • We like that this is such a sturdy and reliable model, even for the most demanding uses. Plenty of people are using this generator for situations like powering their whole house when something goes wrong, and for the majority of people there are no issues, even when powering energy-thirsty air conditioning units. There are plenty of outputs and this is a flexible, versatile generator.

Which disadvantages must you keep in mind?

  • Well, though the weight is to be expected, keep in mind that this is a pretty heavy model which can make it tricky to take from one place to another. It’s fine if you’re keeping it in the basement in case of a power cut, but getting this to a camping trip is another story. The design could also leave the exterior a little prone to rust.

Generac 7676 GP8000EMost Quiet Generator

  • Type: conventional
  • Starting system: electric
  • Peaked/rated watts: 10000/8000
  • Engine: 420 cc Generac OHV
  • Fuel type: gasoline
  • Fuel tank: 7.9 gal
  • Runtime: 11 hours (50%)
  • Outlets: (2) Duplex 120V 20A (5-20R) GFCI, (1) 120/240V 30A (L14-30R)
  • Noise level: 70 dB
  • Warranty: 3-year limited (residential), 1-year (commercial)
  • Dimensions: 27.2 x 27 x 26.5 inches
  • Weight: 198 lbs

This is another option for those who are satisfied with 8,000 watts of continuous power, and it does a really good job of providing this power for a long time, with 11 hours of runtime, compared to some of the competing models that only offer 8-10 hours at a similar capacity.

The weight is also slightly lower than some of the other 10,000 watt models. While 198 lbs is still pretty hefty, it isn’t beyond the realms of possibility to take this out and about on trips with you to give yourself huge levels of power when on the go.

Like a lot of the products on the list, a 3-year warranty is only extended to those who are using the product in a residential setting, if you are in a commercial setting then you might not be able to enjoy this same level of protection as there’s only one year of warranty from the manufacturer.

Many of the top generators are trying to outdo the competition by adding some smart features, and the Generac 7676 has an added feature to “do more with less”. It has 30% more starting capacity, a feature they call “power rush” so in spite of not having to increase the fuel capacity or other functions you can still enjoy this little power boost.

This generator is very rugged in its design, so built to handle even tough environments. There are covers over the outlets to protect them from the elements and the wheels are useful for transport but also guaranteed to never go flat due to their design. There’s a clever “fold-down” handle, easy to whip out and use when you need to move the generator from one spot to the next.

There are some safety features, too, including regular maintenance alerts to warn you when you may need to get the generator seen to or serviced, and added protection in case of low oil, which makes the generator cut out before any damage is done.

There are plenty of outlets to choose between, including multiple Duplex 120V 20A (5-20R) GFCI, (1) 120/240V 30A (L14-30R). It’s easy to hook up your appliances.

What makes it stand out?

  • The run time of this model of generator is just a little bit higher than some of its competitors, giving it the edge in that regard without adding to the actual bulk of the generator so it is still relatively portable, even though we wouldn’t fancy carrying it too far! The Power Rush Advanced technology also makes this model a little “smarter” and more efficient than some of the competing models.

Which disadvantages must you keep in mind?

  • A couple of the components, including the choke lever, could be a little higher in quality in an ideal scenario, but these are minor snagging points. It’s a little bit noisy, but this is to be expected in such a hefty model. In general, it is hard to find anything wrong with the product.

WEN DF1100TBest Dual-Fuel Generator

  • Type: conventional
  • Starting system: electric
  • Peaked/rated watts: 11000/8300
  • Engine: 457cc 4-stroke OHV
  • Fuel type: gasoline, propane
  • Fuel tank: 6.6 gal
  • Runtime: 8.5 hours (50%)
  • Outlets: (4)120V GFCI 5-20R, (1) 120V 30A L5-30R, (1) 120V/240V 50A NEMA 14-50R, (1) 12V DC
  • Noise level: not specified
  • Warranty: 2-year limited
  • Dimensions: 27.3 x 20.6 x 21.9 inches
  • Weight: 214 lbs

“Turn it up to 11” – in this case, we mean 11,000 watts of power, slightly higher than most of the models that seem to settle for 10,000, meaning there’s that little extra bit of surge power. If you are happy running at a standard 8,300 watts most of the time but occasionally need a little bit of extra as the appliances get more demanding then this could be a brilliant choice for you.

WEN is an exceptional name in the world of generators, the company started in the 1950s and it has gone from strength to strength since then. As you would expect, this is one of the most sturdy, yet high-technology models on the market today.

This has a Dual Fuel design which means you can choose your preferred method of power. It is up to you whether you use gasoline or LPG, as there is an LPG hose allowing you to hook it up straight into a propane tank. While there are extra safety precautions to be taken with this, it is great to be able to keep the generator running and not really have to worry about refilling as regularly. If you do choose to run it off the tank, you can use up to 6.6 gallons of gasoline, which provide you with up to 8.5 hours of runtime on half load. This is a little bit lower than some of the other models out there that manage to provide longer with similar capacities.

In terms of the connections, you aren’t short of options, there’s a set of four 120V GFCI outlets (5-20R), a 120V 30A twist lock outlet (L5-30R), a 120V/240V 50A outlet (NEMA 14-50R), there is even a 12V DC cigarette-lighter-style plug so if you have device chargers that would otherwise fit in your cigarette lighter you can connect them here.

There is a two-year warranty that is not limited to people who use it in any commercial setting.  WEN products are undeniably impressive and because the brand are so big, you can rely on their support.  There are service technicians all over the country and even a friendly customer support phone line you can rely on if you have any troubles.

There is a digital display on this model, and an automatic voltage regulator, so these extra safety precautions can come in really handy.

Why is it special?

  • We like the support that you get with this brand, WEN has the infrastructure to support their products, with a 70-year history and plenty of technicians. On top of this, the fact that you can connect it straight to a propane tank is definitely appealing for many uses, as you won’t have to continually refuel. This is easy to do, but make sure you’ve taken the safety precautions.

What are the flaws?

  • A longer run time would be useful, especially if running off the tank, which only gives around 8.5 hours at 50% capacity. If you start to load it more than that, you’ll find the refuel creeps up quicker.

8 Best 50 Amp Generators - Beast of the GeneratorsThere are different types if 50 Amp generators on the market, with the main distinction being the fuel that powers it.

  • Petrol

This type of generator is powered by petrol. It often has a 2 or 4-stroke motor. If it uses a 2-stroke motor, you will need to add some oil to the fuel to act as a lubricant. 4-stroke motors on the other hand do not require the addition of oil.

  • Diesel

A diesel generator offers plenty of advantages, especially for industrial uses. Due to the noise and smell, these are not very common in residential areas. The emissions are also frowned upon by several regulatory bodies. They offer a lot of power, though, which makes it a good choice for anyone that wants it for industrial applications.

  • Propane

Propane generators are very popular and the most common types of generators. They offer plenty of power as well and leave very little emissions. Since they are cheaper to maintain, most people prefer them to other types of generators.

  • Mixed

These are dual-fuel options. They run on propane and gasoline or other combination. Some of the units that we have reviewed on this roundup come with this feature. For example, the Westinghouse WGen9500, Pulsar G12KBN and DuroMax XP12000EH come with this type of function. They start with gasoline then switch to propane. Thus, they have a high starting wattage and longer runtime.

You have to decide which of these types to choose from. If you are using a gasoline or diesel model, you should note that you will have to do more maintenance than on a propane powered generator.

Transfer Switch

If you are using the generator as a backup means of power, then you should consider the transfer switch. It is this switch that will make it safe for the generator to be used when there is a power outage. It makes it easier to power the generator on and will prevent damage to the generator.

In this regard, you have to determine the type of transfer switch your generator should have. There are two types of transfer switches – Automatic and Manual.

These work exactly as their names imply. Apart from the method of switching the generator, the other difference between the two modes is the cost. A generator with an Automatic transfer switch will certainly be more expensive than a manual transfer switch.  Our top pick, the Westinghouse WGen9500, for example, comes with an automatic transfer switch.

Noise Level

The noise level of the generator is an important consideration. It is dependent on the place you plan on using the generator. For example, if you are using the generator in a residential area, noise level would be important to you. You’ll certainly want a model that will not cause too much of a racket.

It might be difficult to find, but the good news is that there are generators that produce a little amount of noise.

Others, on the other hand are noisy. The units that we have considered in this roundup are generally loud with a noise level between 70 and 78 decibels. The DuroMax XP12000EH, for example has a noise level of 76 decibels.


8 Best 50 Amp Generators - Beast of the GeneratorsApart from the initial cost of buying the generator, you also have to consider the cost of maintaining it over time. A generator needs to be regularly checked and maintained, however, some require more maintenance than others.

There are several things that need to be checked frequently, for example, the oil level. Checking it manually can be cumbersome. Thankfully, some units come with screens or displays that will show the oil level of the generator. An example of such a unit is the Pulsar G12KBN. Others on the other hand come with an auto shut-off feature when the oil levels drop below a certain point. This will help to prolong the lifespan of the generator.  An example is the DuroMax XP12000EH.

Fuel Consumption

When choosing a 50 Amp generator, you should certainly consider how economical the unit is in terms of fuel usage. If there is no fuel, there will obviously be no electricity. Thus, you should seek a model that has the correct capacity and economical features that will increase the run time of the model.

From our experience, the generator should have at least five gallon tank capacity. That way, it can go on for some time before you need to refill it. The models that we have reviewed come with different tank capacities. For example, the Champion Power Equipment 100111 has a capacity of more tha 10 gallons and will run for up to 9 hours non-stop at 50% load.

However, in terms of fuel economy, the Westinghouse WGen9500 offers the best on this list. It has relatively small capacity of 6.6 gallons, but can run for up to 12 hours on a 50% load.

So, consider the fuel consumption, tank capacity and the runtime before you make a choice.

Dimensions and Weight

50 Amp generators are powerful, which means that they have sturdy build to carry all of the power. To that end, it is vital that the generator you choose has a reasonable level of portability. To help with that, several units have wheels at the base that let you move them from place to place. If your generator has a large tank, chances are pretty high that it will be quite heavy. Therefore, you should be ready to choose between capacity and portability.

If the generator is meant for work sites, then it is smart to look for a model that has a lower weight. The Pulsar G12KBN is one of the lightest options that you can find that will still give you plenty of power.

When choosing, look for models with wheels and ergonomic handles that will make it easy to transport the generator.

Ease of Use

Buying a generator involves looking at how easy it would be for you to use it. Many come with a control panel that aims to make the generator easier to use. Well, it is important that you consider how easy the generator’s control panel is to understand. Some of the best models have an LCD screen that will tell you the details of the important parameters. An example of this type of generator is the Pulsar G12KBN.

Other might not have an LCD display but offer a gauge.


One of the most important things to consider when buying any electrical appliance is the safety. And this is doubly important when using a generator. Generators use highly flammable fuels, therefore, safety must be prioritized.

The best models on the market have these safety features. Let’s see some of these vital safety features.

  • Surge Protection

This feature ensures that your appliances are safe from any surge in power that can cause damage.

  • Auto Shutdown

This safety feature shuts down the generator when the oil levels drop below a certain point. That way, there is a reduced risk of the motor knocking because of a lack of oil.

  • Spark Arrestor

This excellent feature stops any spark from coming from the motor. This will reduce the chances of fire accidents.


You have to take note of what you want to use the generator for, and if it will have the capacity to power through. The 50 Amp generators come from different brands and have different features, therefore, some are more powerful than others.

For example, the Champion Power Equipment 100111 offers the most power out of the models that we have reviewed.


Generator maintenance is very important. There are several ways to ensure its good, durable performance. You should always ensure the oil levels are at a proper level. You should also cover it when not in use to protect it from the elements.

Some of the 50 Amp generators can be used for small-scale commercial applications. They deliver plenty of power that can run some of your appliances.

Yes, you can. You can even connect different brands together. However, the process is easier and safer if the generators to be connected are parallel-capable. You must also ensure that the generators are inverter types.

This type of generator can give you up to 12000 W. However, check out the manufacturer’s specifications to be sure of the output.
