Why go for a 50 Amp Portable Generator?
A 50 amp portable generator is a generator that offers you a 50 amp outlet. The next question that comes to our mind is why we need a 50 amp outlet. A 50 amp outlet is required to connect heavy loads to your generators such as an RV, powerful appliances at home or work, and construction sites.
How a 50 amp plug differs from a 30 amp plug?
A 50 amp plug is used to connect a 4-prong power cable. It has two 120V hot wires, one neutral and one ground wire. It is used in RVs and heavy appliances where the load requirement is more than 3600 watts.
Can’t we get the work done with a 30-to-50 amp adapter?
Many people suggest that you can use a 30-to-50 amp adapter to connect RV or heavy appliances. It is not the right option, and you will not get the necessary power for your RV. Even if you link your RV to the generator with the help of an adapter, you will have to switch off one appliance to use another. You may need to turn off the AC unit in RV to run the stove or microwave oven. On the contrary, if you have an appropriately sized generator with a 50 amp plug, you will not need to make any compromises during your RV trips or for running your heavy tools and appliances.
Things to take care of while buying a 50 Amp Portable Generator
Before you begin looking for the best generator with a 50 Amp plug, it is better to know what you are looking for and avoid mistakes while buying. First of all, it must meet your power needs so that you don’t have to make any compromises. It must have an affordable running cost, must be durable and user-friendly.

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 chart.
|Appliances||Starting Wattage||Running Wattage|
|1/2 HP Furnace||2350||875|
|1/2 HP Well Pump||2000||900|
|1/2 HP Sump Pump||2000||900|
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.
|Appliances||Starting Wattage||Running Wattage|
|10000 BTU Air Conditioner||2000||700|
|Laptop and Phone Charger||500||500|
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.
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.
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.
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).
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.
The last thing to consider is price. Don’t overspend too much but be generous while you are buying a generator. A generator is a long term investment. The safety of your family, appliances, and generator depends on it. Hence, don’t compromise on quality by saving a couple of hundred bucks.
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.
