Why the 3300W
Quiet. Powerful. Portable.
Everything you need from a generator, for the caravan, the campsite, the job site and the next blackout.
Quiet operation
Quiet for everyone
Nobody wants to be the noisy neighbour at the caravan park or during a blackout at home. Running from just 54 dB(A) at 7 metres, the 3300W keeps noise to a minimum. Its inverter technology adjusts the engine speed when less power is needed, helping reduce noise and fuel consumption.
Real power
Power for the whole van.
Hot nights, cold drinks and morning coffees all need power. With 3000W of continuous running power, the 3300W can handle caravan air conditioners and everyday appliances like fridges, microwaves and coffee machines.
It's also a great option for home backup, keeping household essentials running when the power goes out.

Good to know
Questions people ask
Will it run my caravan air conditioner?
Yes! It will run caravan air conditioners, with 3300W of running power. That leaves room to run other appliances/charges at the same time.
How long does it run on a tank?
With a 7L fuel tank, the 3300W delivers 6+ hours of runtime, with the potential to run even longer on lighter loads. Its fuel-saving inverter technology adjusts engine speed to match power demand, helping reduce fuel consumption when you're using less power.
Is it quiet enough for caravan parks?
It runs from 54 dB(A) at 7 metres, which suits caravan parks and campsites. Always check your park's rules for generator hours.
Is it easy to move?
Absolutely! Weighing just 23kg, the 3300W is compact enough to take caravanning, camping or move around the property when you need backup power. Its built-in carry handle makes it easy to transport without the bulk of a larger generator.
Is it easy to start?
Absolutely! With electric push-button starting, getting up and running is simple. Just add oil and fuel, connect the included battery and follow the easy steps in your Quickstart Guide. There's also a recoil pull-start option as a backup.
What's in the box?
The generator, a battery, the manual and a quickstart guide.
Can I use it to power my home in a blackout?
Yes! With 3000W of continuous running power, the 3300W can keep household essentials running, including your fridge, freezer, lights, internet and phone chargers.
Use suitable heavy-duty extension leads and appropriately rated power boards to connect appliances, without exceeding the generator's capacity. Always operate the generator outdoors, well away from doors, windows and vents. Never connect it directly to your home's wiring.
Can I connect it to my home's power through a changeover switch?
Yes! With a professionally installed generator changeover switch, you can connect your 3300W to your home's electrical system using a suitable lead and dedicated inlet. This allows you to power selected household circuits through your existing power points and switches during a blackout, without running extension leads throughout the house.
A licensed electrician must install the system and confirm compatibility with your generator.
