A portable generator with a 50 amp plug can give up to 12000 watts of output. But not all 50 amp generators can produce this excellent output power.
A generator with a 50 amp outlet will allow you to power your major home appliances, RV appliances, or power tools. It includes four prongs featuring two 120 Volt hot wires instead of one. These hot wires supply two separate 50 amps, 120 Volts feeds.

If you are willing to buy a 50 amp portable generator, check the following seven best generators.
1. DuroMax XP12000EH Portable Generator – Best Dual Fuel 50 amp Portable Generator
Portability: DuroMax XP12000EH is one of the best 50 amp generators. It is a portable machine that can run on gasoline or propane. Its weight is 221 pounds, and it is 22 inches wide, 30 inches in length, and 26 inches in height. But still, you can easily move it around because of its ever-lasting wheels and folding handles.
Power Outlets: The power panel of DuroMax XP12000EH includes a 120/240 Volt 50 Ampere (14-50R) outlet. With this outlet, you can run your main power RV appliances or major home appliances or tools.
Other than this, there are two GFCI 120 Volt 20 Ampere (5-20R) outlets, a 120 Volt 30 Ampere (L5-30R) outlet, and one 120/240 Volt 30 Ampere (L14-30R) outlet along with a 12 Volt 8 Ampere DC outlet is there to charge your batteries.
GFCI-protected outlets are different from regular power outlets. When they sense any disturbance in the current, they immediately break down the circuit to prevent electrical shocks.
With the L14-30R outlet, you can link your generator to your home’s breaker box, and the L5-30R outlet can be used to connect the unit with your RV via an L5-30P to TT-30R adaptor.
Engine and Output Power: It delivers higher output power on gas than propane.
Its 457cc, 18HP, 4 stroke OHV engine gives 12000 starting and 9500 running watts on gas. But when using propane gas, it delivers 10200 peak watts and 8075 rated watts.
MX2 Technology: For heavy loads, the MX2 Technology doubles the 120-Volt amperage. There is an integrated voltage selector switch that allows you to either get the utmost power from each of the 120 Volt receptacles or operate the unit at both 120 Volts and 240 Volts together.
Starting Option: Anyone can start this generator easily as it comes with an electric start system. Also, there is a recoil backup available.
Fuel Tank Size and Runtime: This 50 amp portable generator can run non-stop for up to 9 hours at 50% load on an 8.3-gallon gas tank. It has a built-in fuel gauge to check the level of gas anytime. But a 20-pound propane tank gives you around 4 hours of continuous operation at 50% load.
Idle Control: When there is no load, the idle control feature reduces the engine speed to save fuel. This helps get good runtime.
Fuel Consumption: DuroMax XP12000EH consumes 1.18 gallons of propane per hour but only consumes 0.92 gallons of gasoline per hour.
Operational Sound: The operational sound of this 50 amp generator is 74 dBA.
Voltmeter: The voltmeter is there to show the operating voltage.
Recharge Indicator: It indicates that the battery is recharging.
Oil Alert Lamp: When the oil levels are insufficient, the oil alert lamp senses it and shuts down the engine automatically.
Safety Features: The safety of your generator and connected appliances or tools is in the hands of low oil shutoff and overload protection features.
A low oil shutoff sensor stops the running engine when it senses that the oil level is low.
On the other side, overload protection breaks down the circuit to prevent overheating caused by overloading.
Emissions: Both the EPA (Environmental Protection Agency) and CARB (California Air Resources Board) certifications make this generator environmentally friendly.
Warranty: A 3-year limited warranty
2. Westinghouse WGen9500DF Portable Generator – Most Fuel Efficient
Portability: Westinghouse WGen9500DF is another excellent 50 amp generator. It operates on both propane and gas and has an open frame design. It comes along with 10” wheels and folding handles for easy and safe transportation.
The weight of this generator is 220 pounds, which is equal to the weight of DuroMax XP12000EH. But, it is 27.2 inches in length, 26.5 inches wide, and 26 inches in height.
Power Outlets: It includes a 120/240 Volt 50 Ampere (14-50R) outlet to power your heavy-duty appliances or tools. Also, WGen9500DF features four 120 Volt 20 Ampere (5-20R) household GFCI outlets, one transfer switch ready 120/240 Volt 30 Ampere (L14-30R) outlet, and one smart switch ready outlet.
Power your small or mid-sized household appliances via 5-20R outlets and use the L14-30R to connect this Westinghouse generator with your home’s manual transfer switch. And the best among all is the smart switch ready outlet that provides automatic power to your house during power outages.
All these power outlets mentioned above have rubber protection.
Engine and Output Power: A 457cc Westinghouse 4-stroke OHV engine featuring cast iron sleeve can give 120/240 Volt output and deliver 12500 peak watts and 9500 rated watts on gas. But its output power decreases when using propane, 11200 peak watts, and 8500 rated watts.
Starting Option: It comes with all three starting options: Push-button electric start, Remote start with a key fob, and a Recoil (pull start) mechanism. You can either select manual start options or go for a remote start as per your convenience.
Fuel Tank Size and Runtime: Users will get up to 17.5 hours of continuous operation at quarter load on a 6.6-gallon gas tank, made up of steel. But a 20-pound propane tank can only give you an 11-hour runtime at quarter load.
To extend the runtime of the generator on propane, you can use a big-sized propane tank.
Fuel Consumption: It consumes gas up to 0.38 gallons per hour and propane up to 0.43 gallons per hour.
Operational Sound: 73 dBA is its operational sound.
VFT Meter: With the VFT data center, you can check the operating frequency, voltage, and total run hours of the generator. These displays help users know the generator’s activity and track maintenance intervals.
Safety Features: This 50 amp generator includes low oil shutdown and overload protection.
Emissions: Its engine emissions are safe for the environment as the generator is approved by both CARB and EPA.
Warranty: A 3-year limited residential warranty and a 1-year limited commercial warranty

Consider the following factors when purchasing the best portable generator with a 50 amp plug.
Just to make sure your generator has a 50 amp plug, check its power outlets.
It is always a wise move to buy a generator larger than your power needs. Homeowners should always look for generators that can provide higher output power. You can’t expect a small generator to run most of your electrical appliances or devices during a long blackout. So, to run most of your essential household appliances and get some more comfort, a 50 amp generator is a must.
If you own an RV with a 50 amp service, you can easily connect it with your 50 amp generator. This will help you power much of the appliances and electronic equipment in your recreational vehicle.
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.
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 an 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).
Ease of Maintenance
Make sure your heavy-duty generator is easy to maintain. It must be easy to fill and drain the oil or fuel. Also, your generator must have a VFT data center to schedule routine maintenance easily.
