The Owner's Insights on the Westinghouse iGen3750S Inverter Generator
Twenty-seven kilos, 3,000 watts continuous, and a wireless remote. That's the combination that makes this one work for a caravan or a camp: light enough to lift on your own, powerful enough to run what you actually brought, and you start it from inside.
It's a true inverter with pure sine wave output, so your laptop, your chargers and anything with a control board are safe on it. There are LED lights on the control panel too, which sounds like a gimmick until you're plugging something in at 9pm.
One thing to be clear about: Westinghouse quote up to 8.8 hours run time at quarter load off the 6.3 litre tank. That's the honest number. Run it near 3,000W and you'll be refuelling well inside that.
Why You'll Love the Westinghouse iGen3750S Inverter Generator
- 3,000W running, 3,750W starting. A caravan, a camp or a blackout at home.
- Pure sine wave output. Safe for laptops, chargers and control boards.
- Only 27kg. You lift this one on your own.
- Wireless remote start. Fire it up from inside the van.
- 8.8 hours at quarter load. Westinghouse's own honest figure.
- LED lights on the panel. Plug things in after dark without a torch.
- 240V AC and 12V DC outlets. Household gear and a battery charger.
- 2-year domestic warranty. Backed by Westinghouse Australia.
Why You Should Consider a Westinghouse Inverter Generator

Twenty-seven kilos is the spec that matters
Most inverter generators making 3,000 watts weigh 40 to 50kg, which is a two-person lift or a wheel kit. This one is 27kg, so you pick it up with one hand on your frame and put it where you want it. If it lives in the boot of your car, your camper trailer or your boat, that difference decides whether it comes with you or stays in the shed. It's also why it costs you more than an open frame unit of the same output.
What the run time figure really is
Westinghouse quote up to 8.8 hours at quarter load off the 6.3 litre tank, and that's the number to plan against. Quarter load is your fridge, some lights and charging, which is a normal camp evening. Push it toward 3,000W with a kettle or an air conditioner and fuel use climbs steeply, so expect a few hours rather than eight. That's not a criticism of the machine, it's just how petrol works: small tank, high output, choose one.
Why a pure sine wave inverter matters at a camp
A conventional generator makes power at whatever the engine is doing and lets the alternator sort it out. An inverter converts it to DC and rebuilds a clean 240V waveform from scratch. That's what makes it safe for a laptop, a modern TV, a CPAP machine or a camera charger, which are exactly the things you take camping. On a conventional generator those are the things that quietly die on you early.
The wireless remote and the panel lights
Two small features that get used constantly. The remote means you start it from inside your van when it's raining, or from the back door during a blackout. The LED panel lighting means you can find the outlets and read the display at night without holding a torch in your teeth. Neither is on the spec sheet of a cheap generator, and you notice both every single time.
Is 3,000W enough for you?
Be honest about the list. Three thousand watts continuous covers a fridge, lights, phone and laptop charging, a TV and a small kettle if nothing else is running. Where it stops is a caravan air conditioner alongside everything else, an induction cooktop or a power tool. If any of those are on your list, step up: the HY6000i at 5,500W is the next real jump.

Not Sure Which Inverter Generator Suits You?
The iGen3750S suits you if you want clean quiet power you can carry on your own, for a caravan, a camp or a blackout, with a remote so you're not standing over it. It's the wrong pick if you run an air conditioner or power tools, where 3,000W runs out, or if you need long run times at load, where a bigger tank is the answer. It carries a 2-year domestic warranty. Try the Generator Finder, or call the store on 03 7056 6732.
