With this type of generator, you will take care of your electrical needs without needing to sacrifice using one appliance over the other.

Choosing a 50 Amp Generator

There are several features to consider before you make a buying choice. In this section, we will consider some of these features briefly.

Before you make a purchase, consider the amount of power than you will need. Consider the output of the generator and compare that with the requirements of the appliances that you are looking to run.

You should also consider the starting and running watts of the generator. Other important factors include how long the generator will run and the fuel that will power it.

When all these features, and the others that we will discuss, are considered, then you will be certain to make a wise buying choice.


5 Best 50 Amp Generators - Beast of the GeneratorsThere are different types if 50 Amp generators on the market, with the main distinction being the fuel that powers it.

  • Petrol

This type of generator is powered by petrol. It often has a 2 or 4-stroke motor. If it uses a 2-stroke motor, you will need to add some oil to the fuel to act as a lubricant. 4-stroke motors on the other hand do not require the addition of oil.

  • Diesel

A diesel generator offers plenty of advantages, especially for industrial uses. Due to the noise and smell, these are not very common in residential areas. The emissions are also frowned upon by several regulatory bodies. They offer a lot of power, though, which makes it a good choice for anyone that wants it for industrial applications.

  • Propane

Propane generators are very popular and the most common types of generators. They offer plenty of power as well and leave very little emissions. Since they are cheaper to maintain, most people prefer them to other types of generators.

  • Mixed

These are dual-fuel options. They run on propane and gasoline or other combination. Some of the units that we have reviewed on this roundup come with this feature. For example, the Westinghouse WGen9500, Pulsar G12KBN and DuroMax XP12000EH come with this type of function. They start with gasoline then switch to propane. Thus, they have a high starting wattage and longer runtime.

You have to decide which of these types to choose from. If you are using a gasoline or diesel model, you should note that you will have to do more maintenance than on a propane powered generator.

Transfer Switch

If you are using the generator as a backup means of power, then you should consider the transfer switch. It is this switch that will make it safe for the generator to be used when there is a power outage. It makes it easier to power the generator on and will prevent damage to the generator.

In this regard, you have to determine the type of transfer switch your generator should have. There are two types of transfer switches – Automatic and Manual.

These work exactly as their names imply. Apart from the method of switching the generator, the other difference between the two modes is the cost. A generator with an Automatic transfer switch will certainly be more expensive than a manual transfer switch.  Our top pick, the Westinghouse WGen9500, for example, comes with an automatic transfer switch.

Noise Level

The noise level of the generator is an important consideration. It is dependent on the place you plan on using the generator. For example, if you are using the generator in a residential area, noise level would be important to you. You’ll certainly want a model that will not cause too much of a racket.

It might be difficult to find, but the good news is that there are generators that produce a little amount of noise.

Others, on the other hand are noisy. The units that we have considered in this roundup are generally loud with a noise level between 70 and 78 decibels. The DuroMax XP12000EH, for example has a noise level of 76 decibels.


5 Best 50 Amp Generators - Beast of the GeneratorsApart from the initial cost of buying the generator, you also have to consider the cost of maintaining it over time. A generator needs to be regularly checked and maintained, however, some require more maintenance than others.

There are several things that need to be checked frequently, for example, the oil level. Checking it manually can be cumbersome. Thankfully, some units come with screens or displays that will show the oil level of the generator. An example of such a unit is the Pulsar G12KBN. Others on the other hand come with an auto shut-off feature when the oil levels drop below a certain point. This will help to prolong the lifespan of the generator.  An example is the DuroMax XP12000EH.

Fuel Consumption

When choosing a 50 Amp generator, you should certainly consider how economical the unit is in terms of fuel usage. If there is no fuel, there will obviously be no electricity. Thus, you should seek a model that has the correct capacity and economical features that will increase the run time of the model.

From our experience, the generator should have at least five gallon tank capacity. That way, it can go on for some time before you need to refill it. The models that we have reviewed come with different tank capacities. For example, the Champion Power Equipment 100111 has a capacity of more tha 10 gallons and will run for up to 9 hours non-stop at 50% load.

However, in terms of fuel economy, the Westinghouse WGen9500 offers the best on this list. It has relatively small capacity of 6.6 gallons, but can run for up to 12 hours on a 50% load.

So, consider the fuel consumption, tank capacity and the runtime before you make a choice.

Dimensions and Weight

50 Amp generators are powerful, which means that they have sturdy build to carry all of the power. To that end, it is vital that the generator you choose has a reasonable level of portability. To help with that, several units have wheels at the base that let you move them from place to place. If your generator has a large tank, chances are pretty high that it will be quite heavy. Therefore, you should be ready to choose between capacity and portability.

If the generator is meant for work sites, then it is smart to look for a model that has a lower weight. The Pulsar G12KBN is one of the lightest options that you can find that will still give you plenty of power.

When choosing, look for models with wheels and ergonomic handles that will make it easy to transport the generator.

Ease of Use

Buying a generator involves looking at how easy it would be for you to use it. Many come with a control panel that aims to make the generator easier to use. Well, it is important that you consider how easy the generator’s control panel is to understand. Some of the best models have an LCD screen that will tell you the details of the important parameters. An example of this type of generator is the Pulsar G12KBN.

Other might not have an LCD display but offer a gauge.


One of the most important things to consider when buying any electrical appliance is the safety. And this is doubly important when using a generator. Generators use highly flammable fuels, therefore, safety must be prioritized.

The best models on the market have these safety features. Let’s see some of these vital safety features.

  • Surge Protection

This feature ensures that your appliances are safe from any surge in power that can cause damage.

  • Auto Shutdown

This safety feature shuts down the generator when the oil levels drop below a certain point. That way, there is a reduced risk of the motor knocking because of a lack of oil.

  • Spark Arrestor

This excellent feature stops any spark from coming from the motor. This will reduce the chances of fire accidents.


You have to take note of what you want to use the generator for, and if it will have the capacity to power through. The 50 Amp generators come from different brands and have different features, therefore, some are more powerful than others.

For example, the Champion Power Equipment 100111 offers the most power out of the models that we have reviewed.


Generator maintenance is very important. There are several ways to ensure its good, durable performance. You should always ensure the oil levels are at a proper level. You should also cover it when not in use to protect it from the elements.

Some of the 50 Amp generators can be used for small-scale commercial applications. They deliver plenty of power that can run some of your appliances.
