50 Amp Generator Buying Guide

There are a lot of things to consider when you’re in the market to buy a 50 Amp generator. In this buying guide, we discuss some of the most important things to look out for.

Fuel Type

Fuel types vary from generator to generator, with some running on gas, others propane, and the rest on diesel. On the market, you’ll also find a new group of generators that run on dual-fuel, which basically means a combination of any of the fuels mentioned above. 

Don’t forget to take note of the size of the fuel tank on your chosen generator, as this will give you a good idea of how long you’ll be able to go between refilling. A larger tank is always a better option.

Diesel

The 50 Amp diesel generator has become the most popular choice amongst buyers. The reasons for this are threefold. Firstly, diesel is one of the safest fuel choices, as it is the least flammable. 

Secondly, diesel is widely available across the US, and you should never be too far away from somewhere to restock. Thirdly, diesel is the cheapest of the fuels to buy and run. That’s why so many people choose diesel generator for home use

Propane

Propane-fueled generators are another popular option when it comes to buying a 50 Amp generator. This fuel’s main advantage is that it’s incredibly easy to store, and has a very long shelf life. 

Generally speaking, propane-fueled generators run a lot quieter compared to others, which is perfect if a generator’s noise level is something that concerns you.

Unfortunately, propane is one of the most expensive fuels out there, so remember to take this into consideration when buying your 50 Amp generator too. 

Dual Fuel

Although the initial buying cost is a little higher, a dual-fueled generator has a huge number of benefits to take into account. Not only are these types of generators considered to run more efficiently, outputting a higher power to fuel ratio, but their versatility allows owners to pick and choose between fuels. 

So, if you ever find yourself in a sticky situation where you can’t get your hands on propane, you can opt for gasoline instead. 

30 Amp vs 50 Amp Generator

30 Amp and 50 Amp generators have one primary difference, and that is the type of outlet. While a 30 Amp generator has a 30 Amp outlet with three prongs and a 120V hot wire, a 50 Amp generator has a 50 Amp generator outlet with four prongs and two 120V hot wires.

In simple terms, this means a 50 Amp generator is much more powerful, generating enough wattage to power larger machinery such as power tools and RV appliances. 

Outputting significantly less power, a 30 Amp generator is much more suitable to power much smaller appliances such as microwaves, televisions, or a coffee maker.

Amps Or Watts

Generally speaking, the amount of watts a generator produces is directly proportional to its amps. For example, a 50 Amp generator equates to around 12,000 starting watts of power. 

Of course, this is only an average, and not all generators will be able to produce this output continuously. 

To work out the wattage of a generator you can multiply the Amps by the volts.

Starting Watts vs Running Watts

All generators have two types of wattage: starting watts and running watts. 

This is because some applications require a larger amount of power to start up compared to when they’re running. 

The amount of energy needed to power up a device is known as starting wattage, or in some cases, surge wattage. Any power used after the device has been started is known as the running wattage. 

When choosing the right generator for you, you should pay attention to both of these wattages, and choose one that will power all of the devices that need to be run at the same time. 

Noise Level

There’s no such thing as a silent generator, but there is such a thing as a 50 Amp quiet generator. 

Quiet generators hover somewhere between 55 and 70 decibels, making them perfect for those who want to head for a remote camping trip, or don’t want to anger the neighbors.

The noise level of a generator is typically affected by its size and fuel type. As a general rule of thumb, smaller generators are much quieter than larger ones, and gasoline-fueled and propane-fueled engines are much quieter than diesel engines. 

Portability

Whether you’re hoping to buy an RV generator to power the appliances on your camping trip, or give your tools a surge of power at work, a 50 Amp portable generator is a handy thing to have at your disposal.

There are endless models of portable generators on the market, equipped with easy-to-pull handles, moveable wheels, and even fold-in sections to make transporting the generator a little easier. Looking for these portable features will be of great use to those hoping to travel with theirs. 

If you are hoping to transport your generator around on a regular basis, you’ll also want to consider its weight. 50 Amp generators tend to have larger, bulkier engines that weigh a lot more than smaller models. Unfortunately, this does make them less portable than smaller, lesser-amp generators.

Accessories

Lots of generators come with additional accessories that aim to make their usability even more user-friendly, such as a 50 Amp generator plug or an outlet. If the generator you’ve chosen to buy doesn’t come with added extras, keep a lookout to see if you can buy accessories as addons. 

50 Amp Generator Cord

A 50 Amp generator outlet cord can come in handy if you’re hoping to power several appliances at once. Instead of using an extension lead, a heavy-duty cord set will provide at least four household outlets on one end, allowing you to power many appliances at the same time.

Frequently Asked Questions

Q: What Sze Generator For 50 Amp RV?
A:

The answer to what size generator for 50 amp RV depends entirely on how many different appliances you’re planning to use. Typically, the more devices you want to power, the higher the amp value needs to be.

While most people would recommend anywhere between a 4,000 watt generator and 8,000 watt generator for 50 Amp RV, you should also consider what works best for your RV.

To do this, make a list of all of the items that you’ll need to power in your RV at the same time. This should include everything from your air conditioning unit to your microwave, your refrigerator to your hairdryer.

In the operating manual of each item, you’ll find the starting watt and running watt requirements. Find the running watts of each appliance and add all of them together. This figure will be the minimum wattage that your generator needs to produce.

To be safe, add another 2,000 watts to your minimum.
