Traditional vs Inverter: Why choose an inverter generator?

Now, why should you choose an inverter generator? The answer is simple: safety and convenience. Here are some of its advantages that people know and love:

  • Clean and stable power output, making them safe for powering sensitive electronics and appliances
  • Noise reduction features for quiet and efficient operation, perfect for outdoor enthusiasts and campers
  • Eco-friendly operation, minimising emissions and environmental impact
  • Lightweight and portable design for easy transport and use in various settings

Clean and Safe Power Output

Unlike traditional electric generators, inverter generators convert high-frequency AC voltage to DC power and then invert it back into stable AC via their trim petrol or diesel engine.

This provides a cleaner and more consistent power supply, making it much safer and more efficient for powering sensitive electronics like mobile phones and laptops. So, whether running your reconditioner, charging your laptop, or powering your refrigerator, you can trust an inverter generator to perform well without interruptions.

Conveniently Quiet

An inverter generator is much quieter than traditional generators, producing as much noise as a calm conversation. It can be run comfortably throughout the day and night without causing massive disruptions to yourself or your neighbours. It usually comes in a sound-reducing casing, which considerably limits the noise.

With its noise reduction features, it's excellent as a camping generator. Now, nature-loving adventures can enjoy sleeping under the stars without a problem. It's the best choice if you want to avoid disturbing your fellow campers.

For You and the Environment

Opting for the more environmentally friendly option is not only beneficial for you but also for the planet we call home.

An inverter generator offers several environmental benefits compared to conventional ones, making it a more eco-friendly choice. It's designed to adjust its engine speed based on power demand, which results in greater fuel efficiency. This, in turn, lessens fuel consumption even if it were to produce the same amount of power as a conventional generator, thereby reducing your carbon footprint.

Due to their advanced engine technology, inverter generators also typically produce cleaner emissions. They have much longer lifespans and require less maintenance, which reduces waste and frequent replacements.

Given our planet's current state, it's important to be conscious of our choices. Every decision counts, and opting for more eco-friendly alternatives like inverter generators is a conscious move to reduce your environmental impact and a step towards a greener future.

Portable Power Anytime, Anywhere

Another feature that adventurers love about inverter generators is their portability.

They are designed with convenience in mind. Generally lightweight, compact, and easy to transport anywhere, they are the ideal power source for camping, caravanning, and as an emergency backup. Portable generators offer more convenience than your regular generators on the market.

At Outbax, we understand the importance of portable power, especially for camping and outdoor adventures. That's why we offer various generators tailored to your specific needs. Whether you're looking for a portable generator for camping trips or a powerful backup solution for your home, we've got you covered.

Things to Consider Before Buying an Inverter Generator

Selecting an inverter generator can be overwhelming with all the choices currently available in the market. Here are some points you may consider before making a big purchase:

Power Output

Your inverter generator will be your handy companion for your activities, so you must know how much power you need, which appliances you want to run, and how long you will run them.

To do this, calculate the total wattage of all the appliances and devices you plan to power simultaneously. Suppose you've several appliances to run during a camping trip, including an air conditioner, a refrigerator, and a microwave. In that case, you're probably looking at a portable generator with about 3000W power output, and it must not be below this total wattage to prevent overloading.

You should also consider the generator's rated (continuous) wattage and max (surge) wattage. Keep in mind that some appliances, like air conditioners, may have a surge wattage requirement that is higher than their continuous operating wattage when starting up. It's essential to Use one with sufficient peak wattage to accommodate these spikes in power demand.


Size also matters when buying an inverter generator. Where will you place it? Will you be taking it on camping trips? You must ensure that it fits your storage area and activities.

For instance, if you mainly use it for short camping trips, a portable generator is a more suitable option for extra convenience. The smaller the size, the easier it is to fit in car trunks and carry around wherever your adventure may take you, as they're generally lightweight and powerful.

However, if you need more power and weight is not an issue, the larger power output generators tend to be much heavier and unwieldy compared to lower-capacity generators. Take, for example, our extremely powerful 6000W Gentrax, which weighs 89 kg, against our bestselling 3500W Gentrax, which weighs merely 28 kg.

Some inverter generators also have portability features, such as handles and wheels, for easier transport. If portability is your priority, look for those features.

Noise Level

Inverter generators are known to be a quieter option than traditional ones, but the noise level can still vary among different brands and models. To find out how quiet they are, check the decibel (dB) level provided by the manufacturers. Use this information to compare the noise levels of one generator to another.

Consider the location where you'll be using the generator. Will noise be a concern? For residential areas or campgrounds with noise restrictions, choosing one with noise reduction capabilities is better to avoid disturbing your neighbours or fellow campers.

Brand Reputation and Warranty

Buying an inverter generator can be a significant investment, so it's essential to ensure you get only the best one for your needs. To do this, you may research the reputation of the generator manufacturer. Factors like reliability, customer service, and build quality say a lot about your future experience with their products.

You may also read reviews from other customers to learn about their first-hand experiences with the generator you're eyeing so you know what to expect. Another way to ensure you get the best generator is to check warranty terms, including duration and coverage. This ensures that you are protected against any defects and malfunctions.


Price is an important object when choosing an inverter generator. Set your budget and compare prices among different models while considering the features and specifications that are most important to you.

Furthermore, you must also consider the generator's long-term value, including things like fuel efficiency, durability, and warranty coverage, rather than just the upfront cost. Since inverter generators are more fuel-efficient than traditional ones, they can save you money on running costs in the long run, making them more affordable.

Outbax offers only the most reliable and durable inverter generators for every budget range. We also offer flexible payment terms for a breezy shopping experience.

This buying guide can help you take a more comprehensive approach to choosing the Outbax generator that's right for your needs.

Inverter Generator FAQs

Can inverter generators be used indoors?

No, they should never be used in enclosed structures. You shouldn't run your dog in a garage even with the door open, and you shouldn't run it under your eaves.

Instead, place it on firm-level ground away from buildings or other structures and ensure the exhaust is not obstructed. Manufacturers have warned over the years about the dangers of carbon monoxide poisoning, and yet accidents like this still occur.

For your safety, always make sure that there is sufficient ventilation and exhaust when running your unit.

What is an Inverted Generator?

First things first—it's not an inverted generator! Searching "what is an inverted generator” might give you the same results, but if you're shopping in physical stores, you might want to know the correct name for this to avoid confusion. This is a standard error among shoppers, particularly those who have never used an inverter generator beforehand.

Inverter generators stand out mainly because they are the upgraded version of traditional generators. They're portable and more fuel-efficient, making them a great choice for a variety of applications. Given the daily convenience they bring, it's no surprise they have become a staple among Aussie campers and homeowners over the years.

How to start an inverter generator?

The most common way to start a generator is via the pull option. After fuel has been added, pull it up. It is normal if it does not begin immediately after the first or second pull. Just keep trying until the engine starts.

Some of our inverter generators have other ways to start besides pulling, such as via key or remote control.

Can you leave an inverter generator in the rain?

It would be best never to leave or operate the generator in wet (rain) or snow conditions. You may use a tent to keep the generator safe and dry during use. It also adds an extra layer of protection for your generator.

How to care for and maintain an inverter generator?

Cover the generator and store it in a dry, well-ventilated area when not in use. Habitually clean its exterior and apply a rust inhibitor. Constant checks also help ensure it stays in optimal condition for reliable performance with every use.
