It’s not often that you encounter such a well-made 50A generator for such a low price, so if you need to make your budget stretch, I’d jump on this offer immediately.

If you choose to look elsewhere for a cheap generator, be careful. You may find very cheap generators, but they could come from untrustworthy manufacturers.

I’ve made sure that all of the generators on this list come from trustworthy companies that use quality materials and design their engines well.

Always research the manufacturer before you purchase a generator.

If you buy a generator from a trusted manufacturer, you should be good to go.

Price isn’t an issue. What’s the best 50-amp generator in terms of power?

When it comes to power, I have to recommend the most powerful portable generator I’ve ever seen.

The Generac 5735 GP17500E is by far the most powerful generator on this list.

With an amazing 26,250 starting and 17,500 running watts, this generator can power anything.

While it’s the most powerful on the list, it’s also the most expensive, coming in at a cost of about $2,899.

While it is an expensive generator, know that it’s worth every penny.

It’s an amazing machine that’s guaranteed to power your entire home, RV, tools, and machinery reliably.

I want my 50-amp generator to last for a long time. What do you recommend?

If you want a high-quality generator that will last you a lifetime, I recommend the Pulsar G12KBN.

This generator is equipped with several great features.

The most important among them are the low-fuel shutoff mechanism, air-cooled engine, dual starting options, and dual fuel technology.

The low-fuel shutoff technology automatically turns the engine off when fuel levels drop below a certain level.

The number one cause of internal engine wear is running the engine when the fuel is low or empty. The low-fuel shutoff prevents this damage from occurring.

It’s also equipped with an hour meter and voltage regulator.

The hour meter makes it easy for you to manually monitor how long the engine has been running to make its maintenance even easier.

The air-cooled engine is another great longevity feature.

This efficient design sucks cool air from the environment into the engine. It’s much more energy efficient than traditional fan-cooling, and it’s more effective at keeping the engine from overheating.

Generally, if you want a generator to last for a long time, these are the two main traits to look for.

Air-cooling and low-fuel shutoff are great longevity features in generators.

If you decide to go elsewhere in your search for a long-lasting generator, make sure that they have these two features.

If not, make sure the generator you pick at least has a fuel gauge or hour meter to ensure that you don’t run the generator on an empty fuel tank.

How do I know if I’m overpaying for my 50-amp generator?

Generator prices can vary wildly, especially when browsing those with higher-end output.

For this list, you can use the 1/10th rule when determining whether or not a price is fair.

Take a look at the running wattage of any given generator. Let’s use the DuroMax XP10000E as an example.

The running wattage of this generator is 8,000W. Compare this figure to its price of about $799. I consider this to be a very fair price, as it’s very close to 1/10th of the generator’s running wattage, which is 800.

This albeit becomes a tricky matter once special features are introduced.

When a generator has unique features like dual fuel technology, reduced emissions, quiet engines, or cold start technology, expect the price to rise above the 1/10th threshold.

Use your best judgement to deem whether or not a generator deserves its price tag.

Weigh how much you need those special features with how much you’re willing to spend on them.

If you apply your best judgement and the 1/10th rule, it should be easy to find the best-priced generator for you.

How do I know which 50-amp generator is right for me?

To answer this question, you have to ask yourself a few more.

Consider why you’re reading this article in the first place.

Why are you looking for a generator?

What specifically about 50A generators made you search for them?

a) Do you want a 50A generator that’s convenient to use?

If you need a generator that’s convenient, I recommend the WEN DF1100T.

This generator is equipped with several convenience features including an electric start switch, dual fuel technology, and an easy-to-use mobility feature.

b) Do you want a high-quality 50A generator?

If you want a high-quality generator, look into the Pulsar G12KBN.

This generator is well-designed with dual fuel technology, air-cooled engine, and low-oil shutoff.

These great features and high-quality parts make this generator especially well-designed.

c) Is reliability your main concern?

If reliability is what you need, I recommend the DuroStar DS10000E.

This generator is well-equipped to deal with any and all of your power requirements.

With a durable steel frame, all-copper winding, and both an electric and manual recoil start, you can rely on this generator to power you in any situation.

d) Are you worried about power outages?

If so, the Pulsar PG10000B16 is the best option for you.

This generator is designed to supply power to your whole home or your RV.

It features dual fuel technology, two starting methods, and a durable steel frame.

If you need power in an emergency, this is the generator for you.

e) Do you need your generator to run over long time periods?

When it comes to runtime, no generator comes close to the Firman P08003.

With an amazing 12 hours of runtime, you can rely on this great generator to power your electronics overnight.

Not only does this generator have an incredible runtime and power output, it has a unique key fob included that allows you to start the generator from as far as 168 Ft. away.

f) Are you concerned with electrical safety?

If this is the case, you should invest in the A-iPower SUA12000E.

This amazing generator ensures your safety with GFCI protected outlets that can be enclosed by water-tight plastic flaps.

Additionally, the cords connecting the engine and the power cluster are concealed and neatly tucked inside of a watertight plastic compartment.

You’ll never have to worry about frayed wires or damaged outlets with this generator.

The takeaway from this is to reconsider what kind of generator you wanted coming into this endeavor.

Once you have your desired trait, take another looks at my picks and pay attention to the “Best For:” line.

Why should I get a 50-amp generator anyway?

There are several reasons why you may need a generator in the future, especially in today’s electronic age with many unpredictable situations.

I’ll assume most of you are looking for generators to use on the jobsite or your RV or even at your home or campsite.

50A generators are most commonly used to power heavy machinery, large appliances, tools, and recreational vehicles.

If you own and need to operate either of these things, you’ll need a 50A generator.

Depending on your specific circumstances, look back at my picks and find the generator with the traits you need.

Generators have more applications than RVs and construction sites, however.

One vital function that generators serve is as a backup power source for your home during a power outage.

While we’re under quarantine, and most of us rely on the internet to work remotely and entertain ourselves, electricity is more vital now than ever.

Imagine you’re doing work or streaming a movie until out of nowhere, your home goes dark. It’s only a matter of time until your food in the fridge gets warm and you start getting bored without television and streaming services to keep you occupied.

This is where a generator comes in handy. With any one of the 50A generators I recommended, you can easily power your entire home or power yourself on the go in an RV.

Additionally, you can use generators to start vehicles if their battery dies.

Imagine your car, truck, tractor, or any other vehicle battery dies and there’s no other vehicle around you can use to jumpstart your battery.

If you have a generator, you can easily and safely jumpstart your vehicle’s battery.

This comes in handy especially during emergencies where you need to evacuate your home.

You can also take your generator with you in case you need to start your battery on the go.

Lastly, generators can be used for recreational purposes. You can power your camping trip and other outdoor activities very effectively with a generator.

The more numerous and powerful devices you need to power outdoors, the stronger generator you will need.

If you just need a generator to power small devices, and you want something smaller that you can carry by yourself, I recommend looking into Portable Battery Generators.

These are much less powerful than the ones on this list, but they’re easy to transport.

Best 50 Amp Generator — Conclusion

If you’ve read this far, well done! Now, you should definitely be able to find the best 50-amp generator for your needs and budget.

The generator market can be a very confusing place, as generators tend to vary in shape, size, price, and output.

Congratulations on making sense of this volatile market and narrowing your search down to 50A generators.

I hope you’ve found your perfect generator on my list.

If not, keep the following tips in mind.

Divide the running wattage of a generator by 10 and compare this number to the price. If the price greatly exceeds this number and it doesn’t have many special features, it may be over-priced.

Always buy generators from reliable merchants and manufacturers.

Don’t get reeled in by low prices, as generators are complex machines and must be manufactured correctly and with the best parts.

Lastly, don’t lose sight of why you need a 50A generator in the first place.

If you keep your initial wants and needs in mind, it should be easy to find the best 50-amp generator for you.
