This latest GenTrax 3.5kW is a must-have for holiday lovers. 

Lightweight and portable

This latest design in the Gentrax inverter generator was created with one thing in mind – portability. Weighing just 38 kgs, this 3.5kW generator is designed specifically for Australian campers who don't have that extra room to spare for camping trips. The wheels and the ergonomic handle design add tremendously to the compact design too.

Quiet but powerful

Gentrax has launched this compact inverter generator with the same noise-reduction features, enabling the sound level to go down as low as 58db @ 7m. It makes this device work with the silence of a purr but the energy capacity of a lion – you can power your portable refrigerators, stoves, and lights at the campsite comfortably.

One generator. Several Uses

You can rely on the Gentrax 3.5kW to run your power tools, electronics, lighting and more. This generator generates Pure Sine Wave output, which is excellent for sensitive equipment like laptops and phones. This machine is also a dream come true for handypersons for backup electricity whilst on the job. 

Smart and efficient

Equipped with a digital throttle control, this machine adjusts its output according to the requirements. An automatic throttle also saves fuel and prolongs the lifespan of the motor.

Considering its small size, one wouldn't expect this generator to be able to carry a 7.5L fuel tank. But combined with its state-of-the-art fuel-saving technology, this machine can run for up to 7 hours on a single tank! It's that efficient! And it even comes with an economy switch that can be used to cut down fuel usage and further extend your maximum running time.

Easy to start. Super easy to operate

This 4-stroke machine comes with an easy recoil start which only takes a single pull to start up. And it also has a remote start feature, which means you can turn it on from some distance. 

Why Gentrax?

Gentrax doesn't simply buy engines from one company and combine them with an inverter from another. Their products are engineered from scratch, which is why they can achieve the results that other manufacturers can't.

There's no reason why you shouldn't buy from the most reliable manufacturer because you'll get your money's worth and the best experience ever – guaranteed!

The generator size you need depends on the total wattage draw of the appliance you are running, as well as the max draw. Our generator Buying Guide cuts out the guesswork by explaining what you need to consider. Check out our Generator Buying Guide.
