As avid adventurers, we deeply understand the needs of camping, caravanning and 4WD enthusiasts. The portable generators you find at Outbax have been chosen to offer our customers the highest-performing power products for the lowest possible prices. 

In 2009, when we went looking for a generator for sale that ticked all the boxes – price, quality, fuel efficiency, and portability – we struggled to find anything suitable. This is how our range of Gentrax generators was born. And then, we decided we must share these excellent power generators with the rest of Australia. And, over the last ten years, that’s exactly what we’ve done.

If you’re looking for a generator for sale but are unsure what will meet your power, efficiency, reliability and convenience demands, you can refer to our generator buying guide, designed to help you determine your power needs and how to best meet them. This guide can also help you assess your wattage requirements with tips on maximising the available power output. For example, suppose during a camping trip, you’ve several appliances to run on a petrol generator, including an air conditioner, a refrigerator, and a microwave. In that case, you’re probably looking at a portable generator with about 3000W power output.

Several diesel and petrol power generators can give you that power output. Still, it is essential to examine the efficiency and cost implications of these generators. Another vital aspect is that most appliances have different starting and running wattages. This can impact your choice of power output. If you have multiple appliances with high starting wattages, consider staggering them rather than turning them all simultaneously. Similarly, you can switch off your television while you’re cooking or switch off the lights while watching TV to increase your energy output without increasing your energy needs for a petrol or diesel engine.

Not only does this save you money on running costs and upfront purchase costs, but it will also save you effort and space. A portable generator should be lightweight and powerful, but larger power output generators are usually much heavier and more unwieldy than low-capacity generators. Consider, for example, our extremely powerful 6000W Gentrax that weighs 89 kgs against our bestselling 3500W Gentrax that weighs merely 28kgs. Similarly, using a petrol or diesel generator will require space to store fuel. The less fuel you need to run your generator, the more room you have to pack everything else for your adventure. Efficiency!

If you’re searching for a generator for sale for use at home in the event of a power outage, then we have plenty of options for you. The size of your generator may not be as much of a concern if it’s going to be used predominantly as a backup power supply at home; however, the running noise might be. Check out our silent generator range that produces about as much noise as a quiet conversation and can be run comfortably throughout the day and night without causing massive disruptions to yourself or your neighbours. These generators are designed in a sound-reducing casing which considerably limits the noise. They also contain a sizeable fuel tank and can offer up to six hours of uninterrupted power or even longer when used in economy mode. 

Our range of portable power stations is the next generation in portable generators, offering users access to reliable and continuous power. The power stations work by storing power in powerful batteries and comfortably run 12V appliances and smart devices using USB charging cords. They are also suitable for use with electrical appliances like televisions, laptop computers and electric cookers. They are incredibly lightweight and designed with comfortable carry handles, which makes moving them from site to site simple and easy.

Browse through our selection of solar panels and accessories, including fixedfolding and flexible solar panels and caravan panels that are permanently affixed to your recreational vehicle. Consider using our mini panels and solar blankets for super lightweight options that save you space. These can be stored easily in a backpack and help maximise your available space in your 4WD.

Our complete range of caravanning, camping and 4WD accessories are carefully chosen to offer our customers high-quality products that work as they should and are offered at the lowest possible price. We also offer a range of power sources like lithium batteries as well.

If you’re not entirely sure what kind of generator for sale is going to offer you the most benefit, please get in touch with our friendly team of experts. You can call us on the phone, use the live chat function on our site, or send us your queries via email. As camping and portable power enthusiasts, we know our stuff. We can take you through every generator for sale on our website and explain which products are ideal for your requirements and how you could get the most from your generator in your budget.

What is an Inverter Generator?

Our range of portable generators has consistently ranked among the best portable generators money can buy. An inverter generator uses a small petrol or diesel engine to deliver AC power as conventional generators do. Just that inverter generators convert high-frequency AC voltage to DC power and then inverts it back into a stable AC current. Why is this important? Because it offers uninterrupted power flow to your appliances, making them significantly safer and more efficient than conventional generators. Also, inverter generators are designed to be incredibly lightweight – they are easy to move and hence super portable.

Other advantages of an inverter generator include noise reduction and environmental impact. Because they are significantly more fuel-efficient, by using them instead of conventional generators, you are doing your bit for the planet and enjoying the significant noise reduction.
As part of our commitment to our customers, we’re offering free shipping to metropolitan areas throughout Australia when you purchase a generator from our website. You also enjoy fast shipping with a confirmed dispatch within 24 hours of placing your order with us. Get the best generators available for the lowest possible price at Outbax. Order today.
