What will this 4200 W inverter generator run?
With up to 4.2 kW output, this inverter generator is usually regarded as a home power backup and essential, and it can comfortably run outdoor power tools, coffee machines, or camper appliances. Thanks to its pure sine wave technology, it’s also safe for sensitive electronics like laptops and smartphones.
-
Can I run my house on a 4200-watt generator?
Yes, this 4200W generator can handle many household essentials during an outage, such as lighting, a fridge, fans, computers, and a TV at the same time. However, it may not support the entire house simultaneously—especially if you run high-wattage appliances like electric water heaters or central AC units. Managing load properly will allow it to power key items efficiently.
-
What is the fuel consumption of this generator?
Fuel efficiency depends on the load. Generally, this Gentrax 4.2 kW gasoline inverter generator can last for approx. 6.8 hours at 50% load or 4.5 hours at 100% load when the fuel tank is full with 8.8 L of petrol. Remote start models with eco-mode can extend runtime by reducing fuel use when demand is lower.
-
What appliances can this generator power?
This best-selling Gentrax generator can power appliances that require up to 3.5 kW output for starting and 3 kW output for running.
-
Is this inverter generator good for camping?
Definitely. This portable inverter generator is widely welcomed by campers thanks to its max 4.2 kW capacity and mobility designs featuring 4 wheels and an ergonomic handle, which ensures excellent portability, so you can move it easily across campgrounds. It is a quiet generator, as low as 58 dB at 7 metres, and thanks to a large capacity, it always provides reliable power for camper fridges, lights, and outdoor cooking equipment—making it a top choice as a camper inverter generator.
-
Is the inverter generator beginner-friendly?
Yes—this electric start inverter generator is beginner-friendly. It comes with remote start capability, allowing you to turn it on or off with a button instead of pulling a recoil cord. The remote control design makes it convenient for first-time users, while the clear control panel and automatic overload protection add to the ease and safety of use. Even if you’ve never used a generator before, this remote inverter generator is simple, safe, and intuitive.
-
Can this generator run a 1.6 kW air conditioner?
It can run a 1.6 kW air conditioner as long as the starting power does not exceed 4.2 kW and the running power stays within 3.5 kW.
-
Is there a way to shut off the petrol supply so I can run the carburettor dry?
To shut off the petrol supply, simply switch off the fuel cock.
-
Does the DC protector have to be ON at all times?
The DC protector is switched on by default. It will only pop up if there's an overload in DC. If this happens, you just need to press it back in to reset.
-
Can I use a T-plug adapter to connect a cigarette lighter to my generator?
No. We highly recommend using only the accessories that came with the unit to keep both your generator and other equipment in optimal condition.

What is an inverter generator and why does it matter?
An inverter generator is a type of portable generator that produces electricity in a highly regulated and clean manner by first producing AC (alternating current) electricity, which is then transformed into DC (direct current) power, and then back to AC power with the desired level of voltage and frequency, using inverters. They are known for their fuel efficiency, quieter operation, and clean electrical output, which makes them ideal for powering sensitive electronic devices, such as laptops, smartphones, and medical equipment. They are also typically lighter and more compact than conventional generators, making them easier to transport and store.
What is pure sine wave and why does it matter?
A pure sine wave is a smooth, continuous waveform that oscillates between positive and negative voltage values in a consistently predictable pattern. When it comes to power generating equipment such as inverters and generators, having a pure sine wave output is important because many sensitive electronic devices, such as laptops, TVs, and medical equipment, require clean power to function properly and not be damaged.
What appliances can this generator power?
This best-selling Gentrax generator can power appliances that require up to 3.85kW output for starting and 3.5kW output for running.
What type of oil is best for Gentrax inverter generators?
For Gentrax generators, we recommend using a 10w30 small engine, 4-stroke oil. Here's an example for reference: https://www.supercheapauto.com.au/p/penrite-penrite-small-engine-4-stroke-engine-oil---10w-30-1-litre/346381.html
Can I use this generator in a National Park?
Generally, generators below 65dB are allowed in parks as they are considered quiet generators. Our Gentrax units have an average noise level of 58dB at 7m, which is similar to the sound of a low TV volume. However, it's still best to check with the relevant agency managing the national parks that you want to visit in case of additional requirements.
Does this generator have a digital inverter?
Yes, all Gentrax generators have digital inverter technology, which produces pure sine wave output - a 'clean' energy output that is safe to power sensitive electrical appliances.
