Westinghouse Wgen9500DF is one of the most popular 50 amp generators with dual-fuel capabilities. It is a slightly lighter version than the previous Westinghouse Wgen9500.

It is a very dependable portable power source with enough juice to run the most critical appliances in your home or worksite. It is highly fuel-efficient and powerful.

Westinghouse Wgen9500DF can easily run motor-driven tools, ACs, microwaves, heaters, refrigerators, and other high-power-consuming appliances.

This EPA and CARB-compliant generator can be used at any State in the country. It comes with a 30-year warranty, nationwide support, and incredible customer care.

I love that Westinghouse Wgen9500DF comes with both an electric start and remote control. The remote start will work up to a distance of about 110 yards which is incredible. It is a lifesaver for clumsy-ass guys like me who hate to get up and start the generator in the cold.

Out of the box, we get a measured oil bottle, tools, a user manual, spark plug wrench, a propane regulator, a funnel, remote, and battery float charger.

Westinghouse Wgen9500DF 50 amp generator has an hour meter which is always helpful, a low-oil shutoff feature, and an overload alarm.

There are two 5V USB ports, two 120V 5-20R household plugs, one e transfer switch ready 120V L14-30R, and one RV Ready 120/240V 14–50R plug.

We all know that most 50 amp generators are not quiet, so keeping that in mind, I conducted a noise test from 20 feet away under 50% load, and no load.

At 50% load, I got 79 to 80dB, and at no load, 74 to 76dB. These noise levels are not that bad. In real-time, the sound is not that pungent.

I also conducted the load test and runtime test on gasoline and propane to check their potential.

On gasoline, I ran my fridge, microwave, a small AC, a heater, and some other necessary appliances. The total output power I got was 9390 running watts.

On propane, after cutting a few appliances, I got about 8400 watts.

After that, we ran it on propane at 55% load and it lasted for 7 hours and 5 minutes.

On gasoline, we again ran it at 55% load and it lasted for 12 hours and 6 minutes.

Westinghouse Wgen9500DF is a highly fuel-efficient and powerful 50 amp generator that can easily run most of the appliances in your home, RV, or worksite.

Though it is a bit heavy, noisy, and lacks a carbon monoxide sensor like the Westinghouse Wgen9500DFc version, it is perfect as an emergency backup power source if you don’t want to spend thousands of dollars on a whole house generator.

But, if you want something stationary and permanently installed that starts automatically during power outages, then check our article on the best whole house generators of 2022.

  • Recoil, push-button electric, and remote starter.
  • Highly fuel-efficient and powerful
  • CARB, EPA, and CSA compliant
  • Easy maintenance. Very durable frame
  • Budget-friendly.
  • Perfect for RVs, and as a backup power source
  • A bit heavy and noisy.
  • No carbon monoxide sensor

2. Dewalt DXGNR7000 Outdoor Generator


  • 8750 surge watts, and 7000 running watts.
  • 420cc gasoline-powered quiet engine.
  • 7.5 gal fuel tank
  • Runtime: 11 hours at 50% load
  • Smart runtime meter, wattage meter, and hour meter installed
  • Starting: manual and electric
  • Low oil shutoff. Lifting eye for worksites
  • CARB compliant.
  • Weight 192lbs.
  • Dimensions: 30 x 28.5 x 29 inches
  • Outlets: x1 120/240 14-50R, x2 5-20R 120V GFCI duplex, x1 120/240 L14-30R, automatic idle mode, battery charging outlet.

Equipped with the 420cc gasoline-powered HONDA GX engine, Dewalt DXGNR7000 is a durable 50 amp generator designed by professionals for home and outdoor usage.

Push it to the limit if you want, it can handle high loads without any problem, because it will shut off automatically in case of overload and low oil.

The alternator in the Dewalt DXGNR7000 ensures a minimum harmonic distortion. It generates clean power for sensitive devices such as cellphones, computers, laptops, and DLSR cameras. You can switch between 120 and 240 volts.

Along with the outlets on the control panel, it has a bar-type wattage meter. We never want to overload our generator so it tells whether we are pushing it to the limit, or not.

Beneath that, there is a runtime meter that will tell us how much time is left. There is no manual fuel gauge which is a bummer.

NOTE: Don’t plug in that battery charger for more than 48 hours or you will burn that small battery.

The design of the Dewalt DXGNR700050 amp generator is portable with solid tires and a very grab handle. That handle is A+ from me. It is not awkward to move around.

For the load test, I hooked up four different pieces of equipment to it including a couple of saws and a vacuum. Dewalt DXGNR7000went from idle mode to 3600 RPM in a flash and ran everything at the same time. No bogging at all.

So at 80% of the load, the voltage dropped to 110V, then came back to 127V in a blink of an eye. The recovery is fantastic.

I managed to reach 8000 running watts just for a moment before the overload shutoff.

The noise on this generator is very nice and quiet. It produced about 80dB from 10 feet away.  

It is not as quiet as other 50 amp generators because this unit has the torque to completely get back up to full speed a little bit quicker without any lag.

So the idle mode doesn’t idle down as many other generators do in terms of noise.

So overall there are a lot of good things to say about its performance especially when we talk about recovery time, putting a large amount of load on it all at once and not having this engine lag, or the generator going too low on voltage. It is a big plus for Dewalt DXGNR7000 50 amp generator.

Besides that, Dewalt DXGNR7000 is built solidly with a ton of tiny little details to the design including clean burning of the fuel, but it doesn’t have a fuel gauge which is a downside.

  • From low to high voltage, extremely fast recovery time.
  • Can handle high load
  • Wattage and runtime meter is helpful
  • Superbly built with tiny details
  • Very low harmonic distortion
  • Ideal for RV and worksites
  • No fuel gauge.
  • Can be a bit noisy due to high torque.

3. Generac GP15000E Industrial Generator


  • 22500 starting watts, 15000 running watts
  • 992cc gasoline-powered engine. 16 gallons tank
  • Runtime: 10 hours at 50% load
  • Idle mode, low oil shutoff, and hour meter installed
  • Automatic voltage regulation
  • Highly quality frame
  • Weight: 363lbs.
  • Dimensions: 48.5 x 30.75 x 38.5 inches
  • Outlets: 120V 20A 5-20R Duplex Outlet, 120V 20A 5-20R GFCI Duplex, x2 120V 30A Twist Lock, 125/250V 30A L14-30R Twist Lock, 125/250V 14-50R Outlet,  and x1 12VDC 10A

Generac GP15000E is one of the leading industrial 50 amp generators with the monstrous 992cc OHVI engine generating a whopping 15K watts.

Generac is a highly reputable company largely known for its generators. Their Generac GP15000Eunit provides more than enough power to run an entire house without any trouble.

This machine features an X-Torq governor to maximize the unit’s performance while keeping it running continuously without lagging or bogging.

The idle control mode automatically adjusts the engine speed to provide as much power as required. It is extremely necessary for large generators to save fuel, and reduce noise.

The engine also has a full-pressure lubrication system which can employ an automotive-grade, spin-on oil filter that sifts out dirt, debris, and other unwanted substances.

Generac GP15000E50 amp generator is loaded with outlets and also has a 12V DC battery charger.

Though the design is good with a 1 1/4” hardened steel tube cradle that provides extra strength, those wheels are just crap.

You are gonna have to complain to customer service to improve the quality of the wheels.

In case of power outages, Generac GP15000E provides sufficient power to run your major appliances like ACs, security cameras, and refrigerators all at the same time.

But, in case you will go over the 15000 running watts accidentally, it has a 50 amp breaker that will trip to let you know you are overloading it.

So Generac GP15000E features a muffler to keep the noise levels down, but let’s be honest, a 15000 running watt generator isn’t going to be quiet.

I conducted the noise test from 20 feet away at 50% load, the readings were between 82 to 84Db. It is not super noisy, but not silent as well.

To check its full strength, we gave it a load of the following appliances.

Appliance Quantity  Peak watts Running watts
A standard fridge11200200
Microwave oven110001000
Coffee maker1600600
AC (10,000) BTU144003000
Incandescent lights5300300
Total 835011950

It ran everything without any lag. Later, I pushed it 15800 running watts just for a moment before the overload alarm.

For the runtime test, I ran it at 50% load on a full tank. It lasted for 10 hours and 27 minutes. The efficiency of this unit is superb.

Generac GP15000E is not only powerful and fuel-efficient, but it is highly durable, produces clean electricity, and it is ideal for worksites and homes.

Instead of spending a large sum on a whole house generator, you can opt for Generac GP15000E as an emergency power source.

  • Highly powerful

Champion 7500 is one of the most affordable, powerful, durable, and convenient dual-fuel generators that pumps out 7500 running watts on gasoline, and 6750 running watts on LPG.

Though Champion 7500 is a 50 amp RV generator, it can also be used for residential and commercial purposes.

It has a beautiful open-frame design with tiny details to make it more convenient. It weighs over 200lbs. so it is not a lightweight unit, but it can be managed by wheels and a foldable handle to carry it around.

Initial setup is super easy. It took me only 15 minutes to completely assemble it including the wheel kit.

Along with several different outlets on the control panel including 1x,

120/240V 30A Locking (L14-30R) outlet, 1x 120V 30A Locking (L5-30R), and 4x GFCI 120V 20A Duplex (5-20R)

Champion 7500 features a digital data center that displays frequency, voltage, and runtime.

Like most champion generators, Champion 7500has many safety features including a low oil shutoff, VOLT gaud surge protector, and cold start technology to smoothly start the engine in cold weather.

For the noise test, we took reading from 23 feet away we got about 78 to 80dB. For a 7500 running watt generator, it is not that loud, because we will place it at least 50 to 100 feet away from the camp, worksite, RV, or home. I think the noise is manageable.

I also checked its runtime by running it at 25% load on gasoline. It lasted for 14 hours and 33 minutes on a 6-gallon tank.

Next up was the 20lb LPG tank.  At 50% load, it lasted for 5.5 hours. I was better than what was advertised, but I was expecting more.

Maybe they can improve the fuel efficiency on propane because a lot of guys use LPG cylinders instead of gasoline during camping.

I would say, Champion 7500 is a safe, powerful, fuel-efficient, mildly quiet, and ideal 50 amp generator for house, RV, and camping. It is EPA and CARB certified too.

  • Highly capacity. Fuel efficient
  • Easy to maintain
  • Safe and eco-friendly
  • Longer runtime
  • Several different outlets
  • Affordable
  • Low efficiency on LPG.
  • Heavy.

This unit is the true heavy-duty hybrid generator because it is one of the most powerful, popular, and versatile dual-fuel machines in the generator market.

 DuroMax XP12000EH dual-fuel 50 amp generator is known as the “best heavy-duty generator” due to the 18HP generated by its 457cc overhead valve engine.

It produces 9500 running watts on gasoline, and 9025 running watts on propane which is more than enough power for small homes, outdoor events, worksites, and RVs.

The design of DuroMax XP12000EH is excellent with easy maintenance and a simple starting process, but it is a bit heavy. I move it around easily with those wheels and the handle after I changed them with 10” diameter wheels.

The built-in wheels are terrible. A lot of people replace them, I have talked to their customer service to improve the quality of the wheels.

It starts smoothly without any vibrations and it produces less than 12% harmonic distortion which is not bad for a 9500 running watt generator.

DuroMax XP12000EH is an excellent 50 amp generator due to the capacity of the fuel it can hold. It is not exactly very big in dimensions, but the compact design enables it to store 8.3 gallons of gasoline.

It has five different outlets on the control panel that can be used for household and worksite applications. I use it for my RV though.

I already knew DuroMax XP12000EH is not going to be quiet due to the high power output and big size despite quiet engine technology. I conducted a noise test anyway.

From 5 feet away under no load, I got about 88 to 90dB, and from 30 feet away, I got 75 to 76dB. That is not bad. I was expecting a much louder performance but it surprised me.

I also conducted a runtime test on gasoline and propane at 55% load for both.

  • On gasoline, it lasted for 11.3 hours
  • On propane, it lasted for 20.4 hours

Again, I was very surprised. I was not expecting this much fuel efficiency out of a big-ass generator. DuroMax XP12000EH is a total beast man.

This unit was able to run most of the appliances in my RV including a fridge, AC unit, microwave, TV, an electric place, and other small devices.

The recovery is excellent. From low to high voltage in a flash. It can manage a couple of large power-consuming tools all at once including saws.

Keep in mind that the battery doesn’t always come fully charged, and sometimes the negative is not attached to the battery. It is a common problem with this unit.

So overall DuroMax XP12000EH is a versatile, powerful, and reliable 50 amp dual-fuel generator. It may not be as quiet as a Honda generator, but it isn’t that noisy as well.

  • Duel-fuel. Highly fuel-efficient
  • Very powerful and convenient

WEN DFT1100T has an electric starter along with the manual recoil in case of emergencies. It has an automatic energy controller, and surplus protection.

Gas and propane can be interchanged with a flick of a switch which is cool. It is both EPA and CARB compliant as well.

Like other Wen generators, WEN DFT1100T also creates clean and safe power at 120V AC, 240V AC, or 12V DC to power lights, TVs, sump pump, AC units, refrigerator, power tools, electric heater, and other things.

They gave oil, a wheel kit, a propane connection hose, a spark plug wrench, and a user manual in the package. It took me only 15 to 20 minutes to fully assemble this little beast.

WEN DFT1100T is a pretty heavy machine. Thanks to the wheel kit and handle I was able to move it around freely, but getting it in the back of the truck is a hustle.

Before pouring fuel into it, remember to place it on a flat surface otherwise it will not start because the fuel pickup is on one side.

I took readings after conducting the noise test. From a distance of 20 feet away, the readings were 79 to 81dB. The generator was running was 5700 watts.

WEN DFT1100T recovery time is very good. We pushed it to its limit by running multiple motor-driven appliances at the same time. From low voltage to high voltage, it takes less than a second.

I managed to get 9800 running watts output power on gasoline, and 7814 watts on propane for a moment before the overload alarm.

I also ran it at 50% load on gasoline to check how long it can last. It managed to run for 8.5 hours which is excellent. I checked the hour on is multi-meter.

So overall WEN DFT1100T is a fantastic dual-fuel 50 amp generator with excellent fuel efficiency, high power output, less noise, and strong built.

Things To Consider Before Purchasing The Best 50 amp Generator

There are a lot of 50 amp generators currently on the market. The following factors will help you select the best 50 amp generator for your home, camping, RVs, or worksites at a budget-friendly price.

Power Output:

Most 50 amp generators are designed for backup power sources, and outdoor usage so they come in between 7000 to 15000 running watts.

Power output depends on your usage. First, you need to calculate the wattage of appliances that you want to run:

Watt = Amps x Volts

Also, calculate the starting watts of the motor-driven appliances because they need extra power to overcome inertia to start.

Then, purchase a generator that has a few extra hundred watts than your original need.

If you need 8000 running watts for your home or RV, purchase a 9000 running watt generator.

I would suggest a 9000 or 10000 watts 50 amp generator.

Fuel-Type And Efficiency:

I would suggest a dual-fuel generator if you are an outdoor enthusiast because we never know when we run out of gas.

So having an option of propane is also good. Single fuel is also fine if you are just going to use your generator for residential and commercial purposes.

The fuel-efficiency is the key. At 50% load, your 50amp generator should at least last for 6 to 7 hours because that is the standard. Technology has greatly evolved so why settle for a less fuel-efficient generator.

Fortunately, all the units on our list are super-fuel economical.


All generators make some noise even with the modern quiet technology. For a large 50 amp generator, anything between 78 to 85dB is considered a standard.

Even under the idle mode, 50 amp units will produce some sort of noise. You would have to operate them at least 40 to 50 feet away.

Before purchasing, check the actual decibel levels. We noise tested each generator to get take the real readings.  

A lot of websites are writing fake data. People often complain about the noise after the purchase. So be vigilant and look for the real data.

Size And portability:

Large 50 amp generators are often heavy and hard to pick up. Look for a generator with a wheel and handle to make it portable.

There are a lot of lightweight options available so you don’t necessary to get a heavy-ass unit. I would prefer anything under or a little over 200 pounds. Otherwise, it would be hard to pick it up and put it in the backup of my truck.

Why Should You Buy A 50 Amp Generator?

A 50 amp plug is an absolute necessity for RV guys, campers, and outdoor guys. A 50 amp generator powers most of the appliances we need without connection any extra extension cable.

An average home has either a 100amp or 200 amp circuit breaker. Even the largest portable generators can only cover 25% of the total energy need.

It can run most of the high-power appliances such as refrigerators, AC units, sump pumps, electric heaters, or motor-driven tools.

The best 50 amp generator connects directly to the 50 amp travel trailer, and an RV. These units are mostly recommended for RVs and trailers.

Final Words And Recommendations

I seriously hope you have found your 50 amp generator after reading this article, but if you are still confused, DuroMax XP12000EH, Generac GP15000E, and WEN DFT1100T are my choices if you want my advice.

As an expert in the generator industry, I would suggest getting the best 50 amp generator that is not too heavy and noisy.

Choose a generator that has long runtime to save money.
Check the built quality as well.

Why spend a huge sum on bad material.
