7 Best Portable Generators | Australia 2021 Buying Guide

In today’s modern age we all depend on electricity as our main power source, so getting the best portable generators to ensure you have electricity at all times is the common-sense thing to do.

They can power all your camping trips and RV adventures, as well as allowing you to work in places where electricity isn’t available.

In this article, we’ll explore different portable and dual fuel generators currently on the market, giving you comprehensive reviews and our top pick to help you make the right choice for your needs and budget.

We’ll also take a look at frequently asked questions about petrol generators, inverter generators and dual fuel generators, as well as how to use and maintain them.

So, without further ado, let’s get into it!


What is a Dual Fuel Generator?

Benefits of a Dual Fuel Generator

Petrol generators and inverter generators are pretty straightforward, but there’s some confusion about what dual fuel generators are and how they work, so let’s start there.

Essentially, a dual fuel generator is an electronic household device that uses two types of fuel to generate electricity.

The “dual” part of the name suggests that two different types of fuels are used instead of one – petrol and propane. 

Once one fuel source runs out, the generator will keep on working by switching to the other fuel.

However, the best part about this technology is that the generator mostly uses a combination of the two. This ensures more efficient operation and less fuel consumption, which makes it suitable for those looking to use electric tools in their garden.

Once this electricity is generated, you can just plug in any device you need into the generator through the power outlets.

Although all this sounds pretty simple, there are a few other factors to consider so you can get the best generator for your needs.

Durability and Reliability

The best thing about having a dual fuel generator is the ability to use all your tools and appliances even in a power outage.

Whether it’s an air compressor for DIY projects or a power tool for an emergency, you can rely on the generator to provide you with power for anything you need. 

In addition, they’re built with highly durable and reliable parts, which means that they’ll last a long time.


Even though they cost more upfront than regular generators, they are much cheaper to operate. By using a mixture of two types of fuels, the generator optimizes its fuel consumption, which means you get more electricity for less fuel.


Almost all dual fuel generators are portable generators, which means you can use them both at home and on-the-go. They usually come with high-quality wheels for easy transportation and foldable handles for more compact storage.

You'll never know when you'll need a portable dual fuel generator.

Environment Friendly

Burning gasoline and propane together instead of just petrol means that dual fuel generators are more eco-friendly. Additionally, their efficient operation ensures less carbon emission per watt.

Easy maintenance

The engine of a dual fuel generator is easy to use and maintain. It automatically switches between the fuel types, so you don’t need to do too much.

Benefits of a Petrol Generator


Petrol generators are usually the cheapest models on the market, so they are ideal if you are looking for a portable generator that is very affordable.

 They are also usually a bit lighter too, which matters when you’re hauling it to different sites!

Running Costs

Petrol is cheaper than other fuel types, which makes it very cost-effective to run your generator. Diesel is often said to be more fuel-efficient, but recent breakthroughs in petrol technology has helped these engines compete effectively with diesel counterparts.

Safety Features

Today’s petrol generators have plenty of safety features to make them safe for home use, which helps address the potential risks of the spark ignition system they use.


Petrol engines run more quietly than diesel ones, so they are less likely to disturb residents and neighbours when they are running.

This is an important consideration if your home is fairly close to your neighbours, or if you have to keep your generator close by.


Maintenance is fairly low on petrol generators, although they do run hotter than their counterparts, which can increase wear and tear over time.

Benefits of an Inverter Generator

An inverter generator is not at all like petrol, diesel or dual fuel generators. Instead, it is a battery pack unit that charges off your mains supply or solar power, giving you the ability to run electrical equipment off the high-capacity batteries as needed.

What is a Dual Fuel Generator


These are so quiet! Other than the hum of a small computer fan, you won’t hear a thing, which makes them ideal for home or office use, or for using on camping trips where you want total peace and quiet.

Electricity Quality

If you are running computers, smartphones and other sensitive electronic equipment, you want an inverter generator because these offer very high-quality, clean electricity.

The electricity produced by fossil fuel generators can wear components out over time.

Energy Efficiency

Energy efficiency is determined by the quality of the batteries in your inverter. The best portable inverters have high-capacity, high tech batteries that can store a significant amount of power.

Of course, all batteries have a limited capacity and will require recharging, so you can’t keep them running indefinitely the way you can with a dual fuel or petrol generator.

You can extend the running time by charging the inverter as you use it using solar panels.


These generators are usually the lightest of all generator types, which is a key consideration when you’re looking for something you can transport easily.


These generators charge off your electricity supply, either from your mains or solar panels, so it’s easy to make them exceptionally eco-friendly. Some solar generators even come with their own solar panels for charging!

In addition, they don’t produce any emissions and fumes, so you don’t have to worry about the environment or your nose while you’re running them.

How to Choose the Best Portable Generators

Each portable generator set has different features and specifications, so look out for these things when looking for the best portable generators:

How to Choose the Best Dual Fuel Generators

1. Fuel capacity

The fuel capacity determines how much fuel the generator can store.

The higher the capacity, the fewer refills you’ll need to make, which means you can enjoy uninterrupted electricity for longer. 

2. Power output

Measured in watts, the power output of a generator is a very important thing you need to consider. For starters, you need to know that there are two different outputs: peak and rated.

The peak output is the maximum output which the generator can produce, while the rated output indicates the general power output. Choosing the power output mostly depends on how you plan using the generator. 

For regular camping or RV trips, a lower output should do the trick, but if you wish to use it for your home in blackouts, you’ll need one with more power in order to run all your appliances, lighting, and gardening tools.

3. Safety Features

Safety is extremely important in all household devices, especially in ones that use fuel. The best portable generators should have a few safety features that make them safe enough to use in your home.

These include protection from overheating or overloading, and an automatic shut-down when the fuel is low.

4. Generator Noise Level

Generators produce noise as a result of the internal engine combustion, and this noise can’t be eliminated. However, it can be minimized. Every generator has its own noise level, so choose one according to your needs.

If you plan on using it around your garden, it’s best to find one that’s not overly loud to prevent you from disturbing your neighbours.

How to Maintain Your Portable Generator

Inverters and solar generators require little or no maintenance, although the batteries will have to be replaced at some point according to the manufacturer recommendations. For diesel and petrol generators, you need to:

  • Add and change the oil regularly
  • Drain the fuel tank or add fuel preservative when the generator is not in use. Fuel can decay in as little as 6 months, causing moisture and rust issues.
  • Clean and replace the air filters as needed.
  • Run your generator once a month for 30 minutes to keep it lubricated and operational
  • Keep it clean and clean well before storing in a dry space out of the sun and heat, protected by a cover.
  • Test the generator before you use it for camping, home or work use.
  • Get a professional service once a year.
