Portable Generators with 50 Amp Plug Comparison Chart

Terms used in the below table along with their meanings:

  • G stands for Gasoline
  • P stands for Propane

Starting Watts: The maximum watts a generator can produce are known as starting watts. Starting wattage is also known as peak wattage. They are needed to start motor-driven products like a refrigerator, circular, saw, and air conditioner. Once the appliances are started, the starting watts are no longer needed for that particular appliance and can be used for starting other machines/tools/appliances.

Running Watts: The average output of your generator is known as running wattage. They are needed to keep your appliances running. Running watts are also known as rated watts. Running watts are always less than starting watts.

Runtime @ 50% Load (Hours): It defines how much time a full gas tank or a propane cylinder will run with a half load on the generator.

Our Verdict

If you can’t afford costly generators, then A-iPower is an excellent option for you. It is one of the cheapest generators with 9,000 watts running power and a 50-amp plug. It does the job perfectly and will not let you down during hurricanes, floods, or long working hours. Its runtime is also exceptional, and one full tank can last for 8-9 hours with a 50% load.

When we tested this generator, we found that it is very noisy and the installed muffler doesn’t do a nice job. But do we need to worry about its noise during a storm or a hurricane? I don’t think so. Yes. Noise may be a big concern if you plan to attach this generator with an RV or use it for worksites. Please note that the commercial warranty on this machine is 1-year. The commercial warranty is in line with other leading brands such as DuroMax and Westinghouse. However, the residential warranty is only for 2 years.

User Manual

  • Best runtime
  • Lowest fuel consumption rate
  • Switch & go technology for fuel selection
  • Shaky frame
  • High running sound
Our Verdict

Pulsar’s PG10000B16 is best for people who want to keep their generators in one place. Its frame is a bit shaky. So, it is best for people who have a generator shed in their homes. If your RV has a designated generator frame, you can also use it on the go. However, it is best to avoid moving the generator a lot on the wheels.

Further, if you are looking for raw power at a low price and an impressive runtime, buying this generator won’t be bad. This generator gets a 9/10 rating for factors like ease of use and reliability. It is a noisy unit and will be a nuisance for your neighbors. You will need to attach mufflers or place the unit in a generator enclosure to hush it up.

7. CAT RP12000E Portable Generator–  Heaviest Unit 

  • Fuel Type: Gasoline
  • Starting Watts: 15,000 watts
  • Running Watts: 12,000 watts
  • Voltage: 120 volts
  • Runtime (at 50% load): 11.7 hours
  • Tank Capacity: 13.2 gallons

The output has less than 5% THD, making it safe for sensitive tools and appliances.

The tank size is 13.2 gallons, and the machine can run for more than 11 hours at 50% load. The machine has an idle control feature which is rare in conventional portable generators, and it helps enhance the runtime. The power-runtime ratio is impressive and beats all the models reviewed above. The outlets on this model support the output capacity and give the users freedom to run as many appliances as they need.

Other features in this machine are a data center, low oil shutdown, overload protection, and surge voltage protection. It is only EPA approved machine; you can’t use it in California.

  • Easy portability
  • EPA-approved machine
  • Below 5% THD

It comes with a 2-year warranty for residential and commercial users. You can get an extended warranty of 3 years if you register the product within 30 days of the purchase.

We tested this machine under extreme working conditions and found it reliable, durable, and a powerhouse for big and heavy-duty appliances.

Buyer’s Guide

Consider the following factors when purchasing the best portable generator with a 50 amp plug.

Output and Power Needs

All generators with a 50 Amp plug are significant and provide way more power than a small generator/inverter. So if your power needs are around 2000-3000 watts, you must look for a smaller generator. 50 Amp generators are big boys, meant to power heavy appliances. Selecting the right power output is the first thing while looking for a generator. The best way is to make a list of all the devices you want to power at your home. Find out the starting and running wattage of each machine and then calculate the total. Let’s look at examples for RV and home power calculation charts.

For Home

Appliances Starting Wattage Running Wattage
Refrigerator 1200 200
1/2 HP Furnace 2350 875
TV 300 300
Lights 300 300
AC (2) 3600 2400
1/2 HP Well Pump 2000 900
1/2 HP Sump Pump 2000 900
Security System 600 600
Total 12350 6475

The starting wattage of all the appliances is 12,350 watts, and the running wattage is 6,475 watts. In this situation, you would need a generator with a running wattage of a maximum of 7,000 watts. It is best to add some cushion before buying a generator so you can adjust any extra load on your generator. Now you know how to calculate the wattages. You can edit the table according to your needs.

For RV

Appliances Starting Wattage Running Wattage
10000 BTU Air Conditioner 2000 700
Fridge 600 200
Coffee Maker 600 600
Microwave Oven 1000 1000
Cooking Range 1700 1700
TV 120 120
DVD Player 350 350
Laptop and Phone Charger 500 500
Miscellaneous 300 300
Total 7170 5470

Please note that the starting wattage in the example above is 7,170 watts, and the running wattage is 5,470 watts. In such a situation, a generator with 6,000 running watts will serve the purpose for you. You may have different needs than the one listed above. The purpose of these charts is to help you calculate your wattage needs and assist you in buying the best generator.

Power Outlets

Apart from a 50 Amp plug, you also need power outlets to manage other appliances and power extensions. Your generator must have a 3-leg outlet, car charger outlet, USB outlet, and 2-leg output.

Control Panel

Your generator must have a control panel to assist you in operating it. A fully advanced control panel will tell you about the working condition of the generator, total hours used, wattage drew, and other readings. You will also find buttons and controls on the control panel.


Portable generators are better than standby generators in the sense that they are movable.

50 amp portable generators are very large and heavy, but they come with wheels and folding handles for effortless transportation.

The heaviest 50 amp generator on our list is the CAT RP12000E. It weighs 350 pounds, but it includes durable wheels, folding handles, and a lifting eye for easy mobility.

Single Fuel or Dual Fuel

You can either select a single fuel portable generator or a dual fuel portable generator. But dual fuel generators give you the benefits of both gas and propane at the same time. So, it is better to select a dual fuel generator either for homes, construction sites, or camping.

Start System

Most of the 50 amp portable generators feature recoil and electric start options; however, some units also include a remote start. If it is not easy for you to turn on the generator manually, buy a unit featuring a remote start.

Tank Capacity and Runtime

Always find a 50 amp generator with a big fuel tank. Take the example of CAT RP12000E. It has a 13.2-gallon gas tank, but it is not fuel-efficient, so it fails to give high runtime. On the other hand, Westinghouse WGen9500DF has a decent fuel tank of 6.6 gallons that gives 17.5 hours of runtime at quarter load.

So, along with a big-sized fuel tank, make sure your 50 amp generator is fuel-efficient.


If you are a resident of California, make sure you are buying a 50 amp generator approved by CARB (California Air Resources Board).

Noise Level

Look for a generator that has the lowest noise rating. Though it is not directly related to the generator’s performance, it is related to your peace of mind. You don’t want your neighbors to curse you for disturbing their sleep. You can also use mufflers/silencers to reduce the exhaust sound of your generator.


An ideal generator will offer you safety from working hazards such as voltage surge, low oil and fuel, protection from overloading, and overheating. The frame material, grounding, and generator cover make your experience safe.


Don’t ignore a generator with a warranty. It will help you save hundreds of bucks in case your generator starts troubling you after purchasing it. Hence the warranty is vital. It is also important to read the terms and conditions associated with the warranty.
