Power cut at home? Heading off-grid? Or need reliable power where extension leads fear to tread? Our petrol generators have you covered. Explore portable options at Generators Australia for home backup, camping and job sites, without making it a bigger job than it needs to be.

Petrol Generators for Home, Camping and the Job Site
Petrol generators are a practical choice when you need portable power that's easy to access and quick to get running. Whether you're preparing for a blackout, heading away in the caravan or powering tools on site, there are options to suit different loads and applications.
Home Backup Power You Can Start in Seconds
Petrol generators for home backup can keep essential appliances and equipment running when mains power goes down. Before choosing one, add up the running and starting wattage of everything you want to power. This will help you avoid buying a generator that's too small - or paying for capacity you don't need.
Camping, Caravan and Trade Power On the Go
A portable petrol generator is well suited to camping, caravanning and job sites where access to mains power is limited. For camping, look for a compact, fuel-efficient and quiet petrol generator, particularly if you'll be staying near other campers.
Tradies may prefer higher-output models capable of handling power tools and demanding equipment.

Choosing the Right Size and Type
Not sure where to start? Focus on three things: how much power you need, where you'll use the generator and how often you'll need to move it.
Small Petrol Generators for Light Loads
A small petrol generator can be ideal for lights, chargers, camping equipment and smaller appliances. They're generally easier to transport and store, making them a versatile option when high power output isn't required.
If you're searching for a cheap petrol generator, compare more than the purchase price. Runtime, reliability, warranty support and fuel efficiency can all affect long-term value.
Petrol vs Diesel: Which Suits You Best?
When comparing a petrol vs diesel generator, think about how often and how heavily you'll use it. Petrol generators are commonly chosen for portable, recreational and occasional backup applications. Diesel generators can be better suited to frequent, extended or higher-load operation.
The right choice depends on your required output, runtime, budget and intended use.
Petrol Generator Brands We Stock
Looking for the best petrol generators? Rather than focusing on one model for every situation, compare top-rated brands based on the features that matter to you. Consider power output, runtime, portability, noise levels, warranty coverage and after-sales support.
Inverter vs Conventional Petrol Generators
Inverter generators are a popular option for camping, caravanning and sensitive electronics. They're typically quieter and can adjust engine speed to suit the load.
Conventional petrol generators are often a practical choice when you need higher output for tools, equipment or home backup. Compare your expected load and usage before deciding which type fits best.
