Best Portable Natural Gas Generators Buyer's Guide

Now that we have shown you the best portable generators on offer that can be fuelled with natural gas, it is time to choose which one will be right for you. But how do you narrow down your selection?

Each product is a great option and will do the job, but we have put together some advice on how to identify which generator will be best for your individual needs. 

There are several things you will want to consider when choosing your generator. The first, is whether the dual fuel feature is important to you. The products we have looked at can all be powered by propane or gasoline.

If you think it is likely that you will be using both kinds of fuel, then it might be beneficial to choose a generator with a function that lets you easily switch between the two fuel types. 

Some generators even let you switch whilst the generator is in use. This could be very handy if you suddenly realize you are running out of one type of fuel but you are halfway through a job, or you are powering important appliances that you don’t want to turn off. 

Another thing you will want to look at when choosing between generators is the size of the fuel tank.

The bigger the fuel tank, the longer the generator will be able to run for. However, it will also make the unit heavier and larger, and more cumbersome to move around. It is also more expensive to run a larger fuel tank. 

If you are mainly using your generator as a backup power source for your home, then running time is probably more important than portability. However, if you want to use the generator to power a job site or to take with you on the road then you will want to be able to move it around easily.

Different generators have various types of handles, so look for one that will be comfortable and sturdy to wheel across uneven terrain. Solid-fill tyres are ideal as they will not puncture and deflate. The structure is also important, as metal roll bars will give the unit extra protection. 

If you plan on leaving the generator outside overnight and for long periods of time, then consider getting one with a weather resistant control panel to protect the outlets. Some outlets also have rubber coverings for extra safety which is a good feature. 

Some generators have additional functionality when you buy add-on products, like the ability to automatically connect to certain power circuits in your household in the event of power loss.

This often needs to be configured by an electrician, but is a useful feature if you live in an area where adverse weather events cause you to lose power.  

The final thing to think about is that additional things come included with the generator. Some generators come with tool kits, oil funnels, adapters, cables, battery chargers, and more.

These can be very useful items which you would otherwise have to purchase separately, so it is worth considering the additional items when choosing a generator. 

Frequently Asked Questions 

Which Is Better - Propane Or Gasoline? 

The type of fuel you use comes down to personal preference. Propane is less expensive and offers cleaner burning.

Propane is better for the environment than gasoline, and it can be stored indefinitely. It also reduces the amount of maintenance you need to do on your engine.

However, gasoline usually provides higher wattage and is generally a more efficient source of fuel, producing more BTUs per gallon. It is also easier to get hold of, especially when you are on the road. 

What Can Portable Generators Be Used For? 

There are many possible uses for portable generators. Some people use portable generators as a backup power source for their homes in the event of power loss, such as an outage or an adverse weather event.

They can be used to power medical equipment, which is useful if you are running a mobile clinic or if you have medical equipment in your home. You can use them as a source of power for an outhouse or garage, turning into a more usable workspace or workshop.

Some people use portable generators to power a job site and run their power tools. Portable generators are also very popular with campers and people who own RVs. As they are easy to wheel across uneven terrain, they are perfect for bringing power to more remote areas. 

How Do You Turn On A Portable Generator? 

Some basic generators only have a traditional recoil start up. Others are more advanced and have an electric push start ignition which is much more convenient.

The top of the range generators include a key fob which allows you to start and stop the generator from over 200 feet away. 

Are Portable Generators Noisy?

Some portable generators include a noise cancelling or reducing feature which makes them quieter to run.
