Wattage, starting power, environmental features, efficiency, outlets and price are all important. Here's a quick look at some of our top picks for natural gas generators:

A Look at the Best Natural Gas Generators

1. Mech Marvels 4000 Watt Dual Fuel Portable Power Generator

This powerful dual fuel generator from Mech Marvels can power most household appliances and even power tools. It has a recoil starter, meaning that it is easy to get up and running, and it will run for 10 hours on 50 percent load with a full gasoline tank or a full 20lb LPG cylinder. This makes it a good choice for a backup generator/emergency power source for a home. It's also ideal for use in RVs where you want to be able to run some appliances during the day.

The generator comes with DC wire connectors allowing users to charge 12V batteries as needed. It also includes a 5' propane fuel hose and regulator, so you have everything that you need to make use of the generator. At 95lbs, it is quite bulky, but it is far more powerful than smaller solar generators and can power many more appliances. Since it's likely to either be used static around a home or for tailgating/in an RV, the weight of the generator is unlikely to be an issue. The rugged construction and high burst power makes this a dependable choice at an appealing price point.

This model is a good choice for tailgate parties, use in a small RV, or as a generator for your garage or workshop. It is, admittedly, a little too bulky to be classed as portable, but it is not so heavy as to be impossible to move. It is well-made with a durable metal cage and a casing that should protect it from rust and corrosion. The price point is appealing, being within most people's reach while still offering the performance and build quality that one would like to see from what is an expensive purchase. If you're looking for a generator that you can depend on, and you don't need an output in the 8 to 10k power range, this could be a good choice for you.

Highlights

Watts: 3300W

Starting Watts: 4000W

This generator is best used on work sites or around the home, or for a trailer that tends to send a lot of time at a fixed site. It will allow you to run all of your home comforts without issue and should last for many years with basic care. It can run on gas or LPG, and a full tank of gas should offer 17.5 hours of power, which is one of the more impressive run times for generators on this list.

6. WEN 56180 1800-Watt Portable Generator, CARB Compliant

If you are looking for a portable generator that has a decent amount of power to run appliances on a camping trip, for your RV, for tailgating, or for an outdoor photoshoot or event, this could be the answer.

Why Choose Natural Gas Generators?

Natural gas generators tend to be cheap to run compared to other generators. Natural gas is cheap, readily available, and easy to work with. The technology for natural gas generators is mature compared to some alternatives, and it is something that most households have access to. These factors combine to make natural gas generators more efficient, more affordable, and generally easier to work with.

Compared to solar and battery power banks, natural gas generators tend to be capable of putting out more power too. While there are some high-powered solar generators, they are bulky and comparatively expensive. There are also fewer people who have skills in maintaining them. Natural gas generators, by comparison, are easy to find in the 10KW and above range, and easy to maintain, so once you have one you should find that it will run for many years.

What to Look for in a Natural Gas Generator

If you are shopping for a generator, you should, first of all, think about what you want to use it for. Are you planning on running it as a backup generator? Are you looking for a generator for an RV or for a camping trip? Your plans will impact on the type of generator that you should choose.

Some important factors include:

Fuel Efficiency

 It helps if you can find a generator that has a good running time, especially compared to the size of the tank. Look for a low-emission, highly efficient generator. Take a moment to work out the cost of running the generator in terms of gas per hour. Most modern generators should be very efficient, especially compared to ones that are a few decades old, but there are still variations between modes. It may help if you buy a generator that is a bit more powerful than you need so that you aren't running it at maximum capacity for prolonged periods.

Power Output:

The power output for a gas generator is listed as starting wattage and running wattage. Some appliances - especially things with a motor or a pump - require more power to start than they do to run once they are going. This is why you might sometimes see people turning appliances on in a specific order when using a generator. Your freezer may only require a couple of hundred watts to run, but could pull over 1,000 when it starts up! Make a list of the appliances that you want to run, and calculate the starting wattage and the running wattage so that you have an idea of the initial 'burst' power you need and the long-term running power. Buy a generator that is more powerful than your maximum expected need, so that you have some headroom, and so that you aren't running the generator close to capacity.

Size/weight:

If you are buying a backup generator for your home, then you won't mind too much how heavy or bulky it is, since once it is installed you can forget about it. If you're buying something for use outdoors, or even in an RV, then you may find that you have to move it around more often, and the size, weight, and even quality of the wheels starts to matter. Make sure that you are able to move the generator yourself, and that the build quality is up to the task. If your generator is going to be used on dirty outdoor sites in rough conditions, you should choose one that is resistant to dust and corrosion, and that has a good protective cage around it.

Outlets:

Some generators connect to your electrical supply and will take over the supply when an outage is detected. Other generators are designed to be used as a standalone supply and have a selection of power outlets including household 3-pin connectors, 120V heavy-duty outlets, and 12V DC connectors or USB connectors for portable devices. Consider what you are likely to want to plug into the generator, and make sure that there are enough outlets for this. While you could run extensions from the generator, this is not always a good idea. Remember that standard extension leads aren't designed to be used outside.

Price:

Natural gas generators tend to be affordable compared to other power sources, but that doesn't mean that they are inexpensive. The price can vary from a few hundred dollars to a few thousand. To an extent, how much you pay will be constrained by the wattage of the generator. You are unlikely to find an 8,000W generator for a couple of hundred dollars for example. If you're on a budget, read the specifications of the generators carefully. Remember that you do get what you pay for and that trusted brands with safety features such as spark arrestors and low-oil cutoffs will are worth spending a little extra on if you can find room in your budget.

Warranty

One final consideration is the warranty that is offered. If you are considering purchasing a generator for your home because you have an urgent need for continuous power - for example to power medical equipment, then you will want to have a generator that you can have faith in. Look for a company that offers 24-hour support, has a good reputation, and a long warranty. This will give you some peace of mind.

Fuel Choices

Many of the generators in our list are dual fuel generators that can work on natural gas or LPG. Natural gas is usually more efficient, and less expensive overall. This is why it is so commonly found in homes. If you're hoping to bring your home up to the latest environmental standards then a gas generator is a good choice. It does not produce the odor that propane does, which means that you're more likely to be comfortable having the generator close to your home or RV. Natural gas generators also tend to be quieter while in use, too.

LPG does have benefits for people who want portable fuel for use on the road, but for use on static sites, such as in the home, natural gas wins out in terms of affordability, convenience, cleanliness, and cost.

The generators listed above are all reliable, high-quality generators that serve a variety of different purposes. From small systems for use in RVs or to power the tools that you use in your garage, to systems that will detect power outages and keep the supply running in your home, there are generators for most use-cases.
