7 Best Portable Generators with 50 Amp Plug

Why do you need a 50 Amp Outlet on a Portable Generator?

A 50 Amp outlet has four openings to connect a 4-prong power cable. It contains two 120V hot wires, one ground, and one neutral wire. Four pronged outlets are needed to connect your RV to the generator or heavy appliances for work and construction sites. Some people believe that if you connect an adapter with a 30 Amp outlet and attach a 50 Amp cable to it, you will get the work done. It is not true; you will just get a maximum of 3600 watts of power. It will not be enough to power your entire RV. You will notice fluctuations and tripping while your appliances are running, and you would have to take offloads for running other appliances. For example, you want to run your stove, and if you are using a 30 to 50 Amp adapter, you would have to turn off your AC regardless of the power output of the generator. However, if you were using a 50 Amp outlet and a large generator, you would have to make no compromise, and your RV experience will be smooth as silk.

Problems Associated with Buying 50 Amp Portable Generators

When you are on the hunt for a generator with a 50 Amp outlet, you must make sure of the following.

  • It must fulfill all your power needs and have some cushion to adjust one or two small loads.

Buying Guide

Let’s look at all the factors that can influence your purchase decision.

Power Needs

When you are on a hunt for a generator, you need to make sure that it will deal with your power needs. One should never buy a too large generator or too small generator as compared to his needs. The best way to calculate the power needs is to list all the appliances and their starting and running wattages. If you are buying a dual fuel generator, you must keep the propane wattage in mind. Let’s look at the following table for a better understanding of wattage calculations.

Portable Generator for Home Appliances

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
Total 11750 5875

In the above situation, you need 5875 watts to keep all the appliances running at one time. The starting wattage for all the appliances at one time is 11750 watts. If you do load management and start all the appliances one by one, you can get the work done with a small to medium generator. If you have more appliances to run, you can add the wattages in the above table and then look for the generator according to your needs.

If you plan to buy a generator for an RV, you can take help from the following table.

Portable Generator for RV Appliances

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
Total 6870 5170

The maximum wattage needed to power all the appliances at one time is 6870 watts and to keep them running is 5170. The thing to understand is that not all the appliances will run at one time. You won’t be using a coffee maker all the time or charge your phone 24/7. You need to make sure that your generator has enough power to meet your demands. You can add or remove the appliances in the above table and then make the final calculation.

Power Outlets and Control Panel

Along with a 50 Amp outlet, your generator must have other outlets to facilitate the connections. Some generators come with a car-style charger outlet, and others have USB outlets. The control panel must be easy to use and loaded with maximum options to control the generator. An ideal control panel must have an LCD for readings, circuit breakers, and LED indicators.

Type of Fuel

50 AMP generators come with gas or dual fuel options. Dual fuel generators are a bit costly but offer your versatility for running your generator. A single fuel generator increases your dependability on one type of fuel. Please note that propane gives cheap running costs as compared to gasoline.

Starting Mechanism

Electronic starting gives you ease of use. Almost all the generators with a 50 AMP plug come with an electric start button and a recoil starting mechanism. Electric units need more maintenance as compared to recoil generators.

Fuel Capacity and Run Time

Look for a generator that can give you your desired run time. The size of the fuel tank directly impacts the backup time. However, you must try to buy a generator that offers economical running costs.

Portability

All the generators on our list are with wheels and pull handles. The maximum portability a large generator can give you is moving from one area of your home to another.  If you plan to use your generator for RV, you must make sure that you have enough space for it. It is best to make designated spaces for generators at the front or back of your RV.

Noise Level

Noise level is not directly related to the working of the generator. A low-noise generator will give you peace of mind and will let your neighbors sleep in peace. You can also try high-quality mufflers to reduce sound emissions.

Safety

Look for features that make your generator experience safe. Low oil shut-off sensor, surge protectors, overload and overheating protection, enhance the performance and life of your generator. Safety covers, grounding, a durable frame, and high-quality materials keep you safe.

Warranty and Certifications

Warranty and certifications increase your satisfaction. CARB and EPA certifications allow you to use your generator in all 50 states. A warranty covers relieve you from the maintenance hassles for 1-3 years.

FAQs

How a 50 Amp generator differs from a 30 Amp?

The functionality of both generators is the same. The difference is the power output. A 30 Amp outlet has one hot wire (120V) and can give a maximum of 3600-watt output (120 x 30). On the other hand, a 50 Amp plug has two hot wires and gives 12000 watts (50 x 240). Large wattage can help your power bigger appliances.

Can I use an adapter to convert the 30 Amp plug to a 50 Amp plug?

Yes. You can use adapters to connect 4 prong plugs in 30 Amp plugs. However, it will not increase the wattage. It will only be good for running a four plug appliance under 3600 watts.

Is there any difference in the maintenance need of a 50 Amp plug generator?

No. The maintenance needs of a 50 Amp generator and other generators are the same. You need to take care of the following.

  • Timely oil change
  • Sparkplug replacement
  • No overloading
  • No overheating
  • Don’t store your generator with gas in the tank and carburetor.
  • Air filter replacement
  • Run periodic tests
  • Follow all the instructions in the user manual.

What steps should I take before starting my generator for the first time?

Make sure you follow all the instructions mentioned in the user guide. Check oil in the engine, check battery connections, and never use old gas or propane for the first time use.

How can I save my generator from being stolen?

For RVs, you can make special generator boxes at the front or back. If you are using your generator at home, you can use generator cables and safety locks.

What is the safe distance for running my generator?

You should run your generator at least 15 feet away from your living space.

Can I use my generator without a transfer switch?

You should never use your generator without a transfer switch at your home. If you have to use power extensions, make sure they are of high-quality and can withstand the power output of the generator.

Final Thoughts

A 50 Amp plug gives you the freedom of running heavy machinery, power RV, and your home. You can select the best one from the above list according to your preferences. All the generators are of high-quality, reliable, durable, low running cost models.
