Best 50 AMP Generator Buying Guide

Why Buy a 50 Amp Generator?

You may be tempted to opt for a smaller, more compact generator to save on price like I was. Sure, it’s suitable for things like emergencies and smaller electronics.

The fact remains, however, that a compact generator simply will not be enough to power all of your key electrical items if you get caught in an emergency situation where you need power.

It’s vital to get a generator that will have a higher wattage than the starting and running watts of all the appliances that you need to operate.

This is essential as it means that you will be more than capable of running all of the appliances properly. A 50 amp generator is pretty much vital if you want to run a number of appliances at once.

In the event that you don’t plan to run them all at once, a 50 amp generator is still the best choice as a portable generator may only be capable of giving your around 25% of your overall energy needs.

Okay, so why exactly do you need a portable generator at all? There are a number of reasons why a portable generator is a good investment.

For starters, if you own an electric car then you can actually use a generator as a little charging station. Generators also allow you to have a power source when you’re doing things like DIY projects that require power tools – no batteries or extension cords required.

They can even keep electric pumps powered up in an emergency situation.

In addition to this, they’re a great choice for camping trips if you want to stay connected to electricity and keep your creature comforts.

Things to Consider

When it’s time to buy your 50 amp generator, you really shouldn’t just buy the very first thing that you see. In fact, there are a number of key considerations that you should make before you make your purchase.

Here are a few of the things that you should keep in mind.

Parallel Capabilities of 50amp generators

In some situations, your generator may not be able to give you all of the power that you need to keep your electronics running. In these situations, you should keep an eye out for generators that have parallel capabilities.

This essentially means that if you want a little bit of extra power, you can buy two of the same generators and combine them together in parallel. Not all generators have this functionality.

Sure, the vast majority of generators will give you just enough power to operate your microwave, A/C, refrigerator, fans and more, but at some point you could be stuck in a situation where you need to power much more than this.

If you don’t have enough power, your appliances may not perform well, or you can actually damage the generator. Certainly not ideal.

Most generator manufacturers will suggest that you don’t run numerous appliances at once on just one generator, so if there are a number of appliances that you need to power up at once, then look for a generator with parallel capabilities.


The portability of your generator is largely determined by its weight. Unfortunately, the vast majority of 50 amp generators on the market are exceptionally heavy because they have pretty big engines.

This often means that they aren’t quite as portable as many smaller options.

If you are worried about weight then of course there are options on the market that are lighter. In fact, there are also some options out there that come with wheels so instead of lifting them you can wheel them from one place to another.

On occasion you may need to lift your generator, but wheels can help with this. Nevertheless, before you invest in a generator you should clarify whether the weight is going to be suitable for what you need. 

Noise of a 50amp generator

It goes without saying that every generator is going to create at least a little bit of noise, but this amount of noise can differ from generator to generator.

The vast majority of recent generators actually use something called Quiet Technology which reduces the amount of noise that they are capable of creating. If you’re looking to buy a quiet portable generator with 50 amp RV outlet– the Durostar is probably your best bet.

They can still make noise even with this generator, so while it won’t be completely silent it probably won’t make as much noise as some other options out there.

On average, most 50 amp generators will create around 55 – 70 decibels of noise. This can be a little bit annoying if you’re in a crowded RV park or your generator is in your house.

However, if the generator is working at around 25 to 50% of its capacity then it’s in Eco Mode. This will mean that it will produce a lot less sound than usual.

If you are operating the generator at its total capacity then it’s going to make far more noise than what the manufacturer’s specifications actually suggest. So, in short, noise output is a key consideration to make when you’re selecting your generator.

The last thing you want is for your neighbors to be complaining that you’ve kept them up all night with your noisy generator. You should look for a generator that produces an amount of noise that you can deal with, and try to keep it somewhere discreet when you’re using it to reduce irritation to yourself and your family. 

Fuel Type for a 50 AMP generator

There are some generators that can only run on a certain fuel. For instance, some of them will use propane, or diesel, though gas and propane are usually the most common.

In addition to this, there are a lot of generators that are capable of running on one or two different fuels. Diesel generators are usually pretty difficult to come by.

It’s important to note that some fuels can wildly differ in terms of cost, so you will need to think about the long term affordability of the fuel type that you opt for.

In addition, you should be trying to get a generator that will use the same sort of fuel asyour RV.

This will means that you can buy fuel for both types, making it much more convenient to transfer fuel types if you need to.

You will generally find that propane generators have an extra benefit in that they last longer than gas or diesel generators. With that being said, you will need to think about whether you are going to have a propane refilling station available to you. 


You will find that the vast majority of portable generators come equipped with a warranty that will span a number of years.

If you only intend to use the generator in case of emergencies or for the odd camping trip once a year, then you can opt for pretty much any brand and not worry so much about warranties.

If you intend to use the generator on a construction site and numerous people are going to be using it, then you should be looking for a commercial generator that comes with a longer warranty.

Outlets and Power

To begin with, you’re going to have to work out the amount of power that you’re going to need for whatever you’re doing. Most generators will come with starting watts and running watts, so you will need to figure these out first.

Running watts are what the generator can supply on a consistent basis, whereas the starting watts are what the generator can provide straight away once it’s booted up.

Certain appliances will need high starting watts to get powered up right off the bat.

In addition to this, you should think about the kinds of outlets that you require. The vast majority of generators will come equipped with 120V AC outlets, and may have a small amount of USB ports.

If your generator is larger -around 4000 watts – then it could come with a 240 Volt and a 120 Volt AC outlet, in addition to some USB ports.

In addition to this, if you plan on using the generator mostly outdoors then you should look for a model that has GFCI protected outlets.

Best 50 AMP Generator for your RV


Is it possible to run a generator that’s low on fuel?

Sure, it’s possible, but it’s really not a good idea. If you intend to do this then you will have to shut it down every now and again to make sure that it can cool properly.

Whatever the case, you will need to refuel it after a while. There are some generator models that come up with backup power options and low oil auto shut off, but it’s important not to rely on these features if you want to be able to use your generator for many years to come.

Is gasoline or propane the best power source?

It largely depends on personal preference. 

However, propane usually makes less mess, it’s more economical in the long run and it runs smoother so it’s generally considered to be the better option of the two.

Should I Plug My 50 Amp Into a 30 Amp Service?

Many campgrounds or RV lots come equipped with power sources, most are rated at 30 amps so great for you with a smaller RV!
If you have a 50 amp RV, what are your choices?
If you are in a real pinch, you could use a dogbone electrical adapter. But this is really not a good choice since your 50 amp RV will be trying to pull a higher load than the 30 amp source is able to provide.

The wattage of the 30 amp service is 3600 (30 amp times 120 volts). (check out the best 30 amp rv generators) Compare this to a fully loaded 50 amp RV that may have total peak wattage of 12000 for all appliances. Can you see where this is going?

Most circuit breakers on the 30 amp service work with a tolerance of around 20%. This means that if you start to pull anything over 4320 watts (3600 x 120%) you will trip the breaker.
There may be others also connected to the same service, so in reality you have less than 4320 watts to play with.

If you find yourself using a dogbone adapter, you could always be very careful what appliances you run at the same time, but I would only consider that as a last resort.
