What Is a 50 Amp Generator and Why Should I Buy One?

A 50 Amp generator is basically a generator with a receptacle that allows you to draw 50 Amp of current. It is specifically designed to cater to the power demands of larger appliances and systems, making it an excellent choice for powering RVs, travel trailers, and other heavy-duty applications.

In essence, a 50 Amp hookup has 2 independent hotlines providing 50 amps each, for a total of 100 amps or 12,000 watts (50*2*120). This is over 3 times the amount of power that you’d get from a 30 amp outlet – 3,600 watts (30*1*120).

The ability to output so much power is what makes these generators ideal for large RVs and other situations requiring more power. With a portable 50 amp generator, you will be able to run multiple appliances simultaneously, including air conditioners, microwaves, refrigerators, and more. So, if you need to power appliances or tools that require more than 3,600 watts of power, then you will need a portable generator with a 50 amp outlet.

How to Choose the Right Size 50 Amp Portable Generator?

The first thing to decide is whether you really need all that 12,000 watts a 50 amp portable generator can output. Think of all the appliances that would need power and how many of them you would like to run at the same time.

Let’s say you have an RV with a 15,000 BTU air conditioner (3,500 starting watts, 1,500 running watts), a 1,000-watt microwave, a 900-watt coffee maker, and a 600-watt refrigerator. Your total starting wattage would be 3,500 watts + 1,000 watts = 4,500 watts, and your total running wattage would be 1,500 watts + 900 watts + 600 watts = 3,000 watts.

In this example, you would need a 50 amp portable generator with a minimum power output of 4,500 watts to handle the starting wattage or a generator with at least 3,000 watts to handle the running wattage.

In general, a 6,000-rated watt generator or above should be sufficient to power most 50 amp RVs under normal circumstances.

However, if you are a large power consumer or have a larger 50 amp RV equipped with multiple air conditioning units, you should consider a 50 amp RV generator, such as DuroMax XP12000EH, that produces 8,000 to 10,000 rated watts of power to handle the increased power draw.

Having a generator with higher wattage ensures you always have enough power on tap to run your RV, regardless of the number of appliances or AC units operating simultaneously.

Other important considerations when buying a portable generator include runtime and fuel type (gasoline, propane, or dual). Plus, don’t forget to consider the convenience and safety features that each brand and model offers.

Factors to Consider When Choosing a 50 Amp Generator: A Detailed Buyer’s Guide

When it comes to choosing the best 50 amp generator for your needs, there are several essential factors to consider. A generator is a significant investment, and selecting the right one will ensure that you have reliable power for all your outdoor adventures. Here’s a detailed buyer’s guide to help you make an informed decision:

  • Power Output: The power output, measured in watts, is one of the most critical factors when choosing a generator. A 240v 50 amp generator can typically produce up to 12,000 watts of power, which is more than enough to run multiple appliances simultaneously, including air conditioners, refrigerators, microwaves, and more. To determine the required power output, make a list of all the appliances and devices you plan to power at the same time. Add up their starting and running wattages to find the minimum power output you need.
  • Fuel Type and Efficiency: Generators can run on various fuels, with gasoline and propane being the most common. Some models are dual-fuel generators, allowing you to switch between gasoline and propane based on availability and convenience. Consider the availability of fuel in your area and the runtime provided by the generator on a full tank.

    Fuel efficiency is also important, as it impacts running costs and environmental impact. Look for generators with efficient engines that can deliver longer runtimes on less fuel. A more fuel-efficient generator will save you money on fuel expenses and reduce the need for frequent refueling during extended trips.

  • Run Time: The run time of the generator refers to the duration it can operate on a full tank of fuel at a specified load. Consider the run time, especially if you plan to use the generator for extended periods without access to refueling. A longer run time will ensure that you have continuous power for your camping or RV trips without interruptions.
  • Available Outlets: Check the types and number of outlets provided by the generator. Look for models with multiple outlets, including 120V household outlets, 240V twist-lock outlets, and USB ports. Having a variety of outlet options allows you to connect various devices and appliances simultaneously, improving the generator’s overall versatility.
  • Noise Level: Noise can be a significant concern, especially if you plan to use the generator in quiet camping areas or residential neighborhoods. Check the decibel (dB) rating of the generator to understand how loud it will be during operation. Many modern generators come with noise-reducing features and technologies to offer quieter operation. Look for a generator with lower noise levels to ensure a more peaceful and enjoyable outdoor experience.
  • Portability: If you’ll be moving your generator frequently, consider its weight and physical dimensions. A portable generator with built-in handles or wheels will be easier to transport from one location to another. Keep in mind that larger generators tend to be heavier and more cumbersome to move, so strike a balance between power output and portability based on your specific needs.
  • Safety Features: Safety should be a top priority when selecting a generator. Look for models that come with essential safety features such as low-oil shutoff, which automatically turns off the generator if the oil level is too low, preventing engine damage. Overload protection is another critical safety feature that shuts down the generator if it is overloaded, safeguarding both the generator and your connected appliances.
  • RV Ready Features: If you’ll be using the generator primarily for your RV or travel trailer, look for RV-ready features that simplify the connection process. A 50 amp RV plug on the generator will make it easier to connect to your RV’s power system securely and efficiently. Some generators also come with additional RV-specific features, such as dedicated RV outlets or compatibility with RV power management systems.
  • Brand Reputation and Warranty: Consider the reputation of the generator brand and the warranty provided. Established and reputable brands often offer better customer support, reliable products, and better warranty coverage. A longer warranty period gives you peace of mind and assurance in case of any manufacturing defects or issues with the generator.
  • Additional Features: Some generators come with extra features that enhance convenience and usability. For example, an electric start feature allows you to start the generator with the push of a button, which is easier than using a pull cord. An automatic voltage regulator (AVR) ensures stable and consistent power output, protecting your sensitive electronics from voltage fluctuations.
  • Price and Budget: Set a budget for your generator purchase and compare various models within that range. While it’s tempting to go for the cheapest option, remember that a generator is a long-term investment, and choosing a higher-quality model may offer better performance, durability, and overall value in the long run.

By considering these factors, you can select the best portable generator with 50 amp outlet that meets your specific power needs, offers reliable performance, and enhances your outdoor experiences.

Frequently Asked Questions

How many watts is a 50 Amp generator?

A generator with 50 Amp receptacle has the potential to output 12,000 watts (50 amps by 240v). However, not all models are capable of outputting this amount of power continuously. For instance, while Champion 201067 has a 50 amp outlet, it can only output a peak of 9,000 watts. On the other hand, the Duromax XP12000EH outputs 12,000 watts of starting power before dropping to 9,500 running watts.

What is the best 50 amp portable generator?

Our reviews suggest that the Westinghouse WGen9500DF is a top contender for the best 50 amp portable generator. It offers a combination of impressive power output, dual-fuel capability, and reliable performance. However, there are other viable options worth considering as well. Make sure to explore the other generators from our list to find the one that best suits your specific needs, as individual requirements may vary.

What is the difference between 30 amp and 50 amp generator?

The main difference is the type of outlets. The one has a 30 amp outlet, and the other – 50 amp outlet. The difference between these receptacles is that a 30 amp outlet has 3 prongs including only one 120v hot wire. On the other hand, a 50 amp outlet has 4 prongs and features two 120v hot wires that supply 2 separate 50 amp, 120v feeds.

Precisely, a 30 amp generator can output a maximum of 3,600 watts at 120v (30 amp x 120v). On the other hand, a portable generator with 50 amp outlet can deliver 12,000 watts at the same voltage (50 amp x 2 x 120v). More details on how to convert amps to watts here.

Is a 50 amp generator better than a 30 amp generator?

Whether a 50 amp generator is better than a 30 amp generator depends on your specific power needs. A 50 amp generator offers higher power output and can handle more significant electrical loads, making it suitable for larger RVs and applications that require more power. If you have a smaller RV or don’t require as much power, a 30 amp generator may be sufficient for your needs.

Is it possible to plug a 30 amp RV into a 50 amp plug safely?

Yes, it’s very much possible. But keep in mind that these 2 plugs have different configurations. A 30 amp receptacle has a 3-prong design while a 50 amp outlet has 4 prongs. Thus, you’ll need a 30 amp female to 50 amp male adaptor (a.k.a dog bone) to make the connection possible.

Does Honda make a 50 amp generator?

They had one- the 5500 watts EU6500is- but it has been discontinued.

What generator has a 50 amp RV plug?

Many reputable generator brands offer models with a 50 amp RV plug. Some popular options include models from Champion, Westinghouse, DuroMax, and Generac. When searching for a portable generator for a 50 amp RV, look for models explicitly designed for RV use or those labeled as “RV-ready”, such as DuroMax XP12000EH.

How many amps will a 12,000-watt generator run?

To determine the number of amps a 12,000-watt generator can run, divide the wattage by the voltage. In most cases, generators produce 120 volts in the United States. So, 12,000 watts divided by 120 volts equals 100 amps. Therefore, a 12,000-watt generator can handle a load of approximately 100 amps at 120 volts.
