Why Choose a Petrol Inverter Generator?

A petrol inverter generator is all about convenience and control. Unlike traditional models, these inverters convert DC to AC power with precision – keeping your electronics safe while reducing fuel burn.

If you're charging a laptop, phone, or running sensitive tools, a petrol inverter generator gives you pure sine wave power – the same stable current you'd get at home. That means no flickering lights, no overheating, and no worries about damaging your devices.

Heading off-grid or working in noise-sensitive areas? These generators are known for their quiet, efficient running. They automatically adjust engine speed based on load, saving fuel and keeping things peaceful – perfect for long weekends, job sites, or emergencies.

Petrol Inverter Generators FAQs

What size petrol inverter generator do I need?

It depends on what you're running. A 2000-2500W unit handles a fridge, lights, and phone charging - good for camping or a small worksite. Step up to 3500-5000W if you're running power tools, a compressor, or air con. Go 8kVA+ for heavy trade use or a whole-site backup. True Gear stocks petrol inverter generators from 2.5kVA right up to 13.75kVA, so there's an option for pretty much any job.

What's the difference between a petrol inverter generator and a regular generator?

A standard generator runs at a fixed RPM regardless of load, which means more fuel burn and rougher power output. An inverter generator adjusts its engine speed to match the load, so it's quieter, more fuel-efficient, and produces clean sine wave power. That clean power is safe for sensitive electronics like laptops, phones, and modern tools with variable-speed motors - things that a conventional generator can damage over time.

Are petrol inverter generators safe to use for camping and caravanning?

Yes - they're one of the most popular choices for campers and caravan owners. The clean power output means you can safely run your CPAP, laptop, or 12V charger without risk. Models like the Welling & Crossley Smart Silent range and Champion inverters are designed to run quietly enough that you won't annoy your campsite neighbours. Just keep the generator outside and well away from any enclosed space - petrol engines produce carbon monoxide, so never run one inside a tent, camper trailer, or caravan.

What brands of petrol inverter generator does True Gear stock?

True Gear stocks inverter generators from Welling & Crossley, Westinghouse, Champion, Hyundai, Briggs & Stratton, and Macfarlane Generators. Prices range from around $999 for a compact 2.5kVA unit up to $3,659 for a heavy-duty 13.75kVA model. All brands sold through True Gear come with Australian warranty support.

How quiet is a petrol inverter generator?

Most modern petrol inverter generators run between 52-65 dB at 7 metres - roughly the same volume as a normal conversation. At lower loads they're quieter still, since the engine throttles back automatically. Models marketed as 'silent' or 'smart silent' - like the Welling & Crossley Smart Silent range - sit at the quieter end. For comparison, a standard open-frame generator typically runs at 70-80 dB, which is noticeably louder.
