Petrol Generators FAQs

What size petrol generator do I need for camping or the job site?

It depends on what you're running. For camping - a few lights, a fridge, and charging gear - a 3,000-4,000W inverter generator is plenty. On the job site, if you're running power tools or compressors, you're looking at 6,000W-9,000W or more. For heavy-duty or standby use, Gentech's Honda-powered units go up to 20kVA. True Gear stocks a range across all these sizes so you can match the generator to the load.

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

A conventional generator produces power at a fixed RPM - it's loud, uses more fuel, and the power quality isn't as clean. An inverter generator adjusts engine speed to match the load, so it's quieter, more fuel efficient, and produces clean sine wave power that's safe for sensitive electronics like laptops and phones. If you're camping or using it around people, inverter is the way to go. For pure grunt on a work site where noise doesn't matter, a conventional unit can give you more watts for the dollar.

What brands of petrol generator does True Gear stock?

True Gear stocks petrol generators from Gentech, Welling and Crossley, and Westinghouse. Gentech units are Honda-powered, which is a big tick for reliability and parts availability across Australia. Welling and Crossley offer smart silent inverter models at competitive prices. Westinghouse rounds out the range with units like the iGen4750s that include remote start.

How much does a petrol generator cost in Australia?

Prices vary a fair bit depending on size and type. Compact inverter generators start around $1,000-$1,100 for a 3,200W unit. Mid-range inverter models in the 6,000-9,000W bracket sit between $1,800 and $3,400. Honda-powered Gentech units in the 7-8kVA range run $2,400-$3,300, and heavy-duty 20kVA commercial units are around $8,500. True Gear's range covers most budgets, and prices shown include GST.

Do petrol generators come with a warranty in Australia?

Yes. All petrol generators sold through True Gear come with an Australian warranty. Gentech Honda-powered units are backed by Gentech's local warranty, and because they use Honda engines, parts and servicing are available nationwide. Welling and Crossley and Westinghouse units also carry manufacturer warranties. If something goes wrong, you're not chasing an overseas supplier - True Gear is based in Australia and the brands it stocks have local support.
