With over 680,000 registered recreational vehicles on Australian roads, the dream of exploring remote coastlines and outback landscapes has never been more achievable. Yet while caravanning offers unparalleled freedom, maintaining modern comforts while off-grid presents a genuine challenge. The solution lies in selecting the right inverter generator—a piece of equipment that delivers reliable, quiet electricity without the excessive noise and fuel consumption of traditional models. Unlike conventional generators that run at constant speed regardless of power demand, inverter generators adjust their output intelligently, producing clean electricity suitable for sensitive electronics while respecting the tranquillity of remote campsites. This guide examines the technical considerations and practical features that determine which model will best serve your specific requirements on extended RV trips.
Why an Inverter Generator is Essential for RV Travel
Understanding the fundamental distinction between an inverter generator and a conventional generator clarifies why experienced travellers consistently choose inverter technology. Traditional generators produce electricity through a simple alternator that spins at a constant speed, generating raw AC power with significant fluctuations in voltage and frequency. Outbax inverter generators employ a more sophisticated three-stage process: they generate AC power, convert it to DC, then invert it back to stable AC power through advanced electronics. This process delivers several measurable advantages that directly impact your camping experience, from respecting campground noise regulations to protecting valuable equipment from power surges. The comparison between these technologies reveals why inverter models have become the preferred choice for serious RV enthusiasts.
Quiet Operation for Peaceful Campsites
Inverter generators operate at significantly reduced noise levels, typically between 50-65 decibels—comparable to a normal conversation rather than the industrial roar of traditional models. This quieter operation results from variable speed engines that adjust RPM based on electrical demand, combined with sound-dampening enclosures and advanced muffler systems. Most campgrounds enforce strict noise limits, often prohibiting generators above 65 decibels during evening hours, making a quiet generator essential for compliance. Beyond regulations, reducing noise pollution demonstrates respect for fellow travellers who've chosen remote locations specifically for their peaceful atmosphere. When your generator runs as quietly as a background conversation, you'll avoid the social friction that loud equipment inevitably creates in shared camping spaces.
Clean Power for Your Sensitive Electronics
The term "clean power" refers to pure sine wave output—electricity that maintains consistent voltage and frequency without the harmonic distortion produced by conventional generators. Modern RV trips involve numerous sensitive electronics: laptops for remote work, smartphones requiring frequent charging, televisions for evening entertainment, camera equipment for capturing memories, and potentially medical devices like CPAP machines.
Pure sine wave inverter generators protect these valuable items from damage caused by power fluctuations, which can corrupt data, reduce battery lifespan, and even destroy delicate circuitry. Conventional generators produce modified sine wave or square wave output that may cause electronics to overheat, emit strange buzzing sounds, or simply fail to operate correctly. For travellers carrying several thousand dollars’ worth of electronic equipment, investing in clean power generation isn't optional—it's essential protection.
Superior Fuel Efficiency for Longer Adventures
Advanced inverter generators, like Gentrax, incorporate eco-mode technology that automatically adjusts engine speed based on real-time power demand, delivering 20-40% better fuel efficiency compared to traditional models running at constant speed. This intelligent load-sensing capability means your generator consumes minimal fuel when powering only a few LED lights, then seamlessly increases output when you activate the microwave or coffee maker.
The practical benefits extend beyond environmental considerations: longer run times mean fewer refuelling stops during extended trips through remote areas where service stations are scarce, reduced fuel costs accumulate significantly over a season of travel, and smaller fuel tanks become viable without sacrificing operational duration. When exploring areas hundreds of kilometres from the nearest town, fuel efficiency directly translates to extended range and increased peace of mind.
A Step-By-Step Guide to Calculating Your Power Needs
Accurately determining your power requirements prevents both the frustration of insufficient capacity and the unnecessary expense of oversized equipment. This calculation process requires understanding two distinct measurements and cataloguing your specific appliance demands, but the methodology itself remains straightforward enough for anyone to complete within an hour.
Understanding Starting Watts vs Running Watts
Running watts represent the continuous power an appliance requires during normal operation, while starting watts—also called surge watts—indicate the temporary spike of power needed when electric motors initially start up. Refrigerators, air conditioners, and power tools commonly require 2-3 times their running wattage for the first few seconds of operation as motors overcome initial resistance. Your generator must handle the highest starting wattage of any single appliance, plus the combined running wattage of all other devices operating simultaneously.
Consider this practical example: if your caravan air conditioner requires 3,200 starting watts but only 1,800 running watts, while your refrigerator runs constantly at 150 watts, your generator needs at least 3,350 watts of capacity (3,200 starting + 150 running). Underestimating starting watts represents the most common sizing mistake that leads to generator overload and potential appliance damage.
How to Tally Your Appliance Wattage
Create a comprehensive list of every device you intend to operate simultaneously, then research each item's power specifications—usually found on the manufacturer's label or in the owner's manual. Common RV appliances typically consume the following power: caravan refrigerators (150-400 running watts, 600-1,200 starting watts), microwave ovens (800-1,500 watts), small air conditioners (1,500-2,000 running watts, 2,800-3,500 starting watts), televisions (50-200 watts), laptop computers (50-100 watts), LED lighting (5-15 watts per fixture), and coffee makers (800-1,200 watts).
After listing your specific appliances, identify which combination will run simultaneously during peak usage—typically morning or evening when cooking, charging devices, and running climate control all occur together. Calculate your total requirement using this formula: (Highest Starting Wattage of Any Single Appliance) + (Sum of Running Watts for All Other Simultaneously Operating Devices) = Minimum Generator Capacity Required. Adding a 10-20% safety margin above this calculated minimum provides headroom for unexpected additions or power fluctuations.
Key Features to Look for in a Portable Inverter Generator
Beyond basic wattage capacity, several specific features significantly impact usability and long-term satisfaction. Portable inverter generators vary considerably in design details that affect daily operation, and understanding these distinctions helps identify which models offer genuine value versus unnecessary complexity. Portability fundamentally depends on weight and physical dimensions—while a compact unit like the Aussie Traveller MC1000 weighs under 10 kilograms and features integrated handles for effortless transport, larger models exceeding 30 kilograms become challenging for a single-person setup, particularly for older travellers or those with physical limitations.
Parallel capability represents an increasingly valuable feature that allows connecting two identical smaller units to achieve doubled power output, offering superior flexibility compared to a single large generator. Two 2,000-watt generators operating in parallel deliver 4,000 watts when needed, yet either unit alone suffices for lower-demand situations. Electric start functionality eliminates the physical strain of pull-cord starting, while remote start capability—found on premium models like the Gentrax GTX3500 Inverter Generator—enables activation from inside your caravan on cold mornings or during inclement weather. Finally, verify adequate outlet options including multiple 240V AC sockets, 12V DC outlets for direct battery charging, and USB ports for modern device charging without requiring separate adaptors.
Here’s what one of our customers said about the Gentrax GTX3500:
“Recently purchased one of these gennys. I have a generator switch in my power board and when the genny is hooked up it runs all the lights, power points and fans easily. As well as being able to do some washing. Great little unit at a fair price and fast delivery. Thanks”

These units comfortably handle LED lighting throughout your van, multiple phone and laptop chargers operating simultaneously, portable fans for air circulation, small televisions, and basic kitchen appliances like electric kettles or single-burner cooktops.
Models such as the Gentrax GT1200 typically retail under $500, making them accessible entry points for occasional travellers or those supplementing other power sources like solar panels. The primary advantages extend beyond initial cost—these remain one of the lightest options (often under 15 kilograms), operate at the quietest levels, and achieve the longest run times per litre of fuel. However, they cannot power air conditioners, large microwaves, or multiple high-draw appliances simultaneously, making them unsuitable for families or extended off-grid stays during extreme weather.
Mid-Size Generators (2,200W – 3,500W) for All-Round Comfort
This versatile category represents the most popular choice for serious caravanners, delivering sufficient capacity for most common appliances while maintaining reasonable portability. Mid-sized units power everything available to smaller generators, plus microwaves for convenient meal preparation, coffee makers for morning routines, hair dryers, and crucially, small-to-medium caravan air conditioners that dramatically improve comfort during summer travel.
Models like the Gentrax GTX4200 Pro or VoltX VX3850 Pro typically cost over a thousand dollars, representing worthwhile investments for regular travellers who refuse to compromise on essential comforts. Outbax stocks multiple options within this category, reflecting its position as the optimal balance between capability and practicality for most Australian caravanning scenarios. These generators typically weigh 20-30 kilograms—manageable for two people but potentially challenging for solo operation—and deliver 8-12 hours of runtime at moderate loads.
Here’s what one of our customers said:
“The generator is excellent. Starts easily, is very quiet, and runs for 5 hours or so on a tank of fuel. Importantly, its easy to handle. Re the service and delivery from Outbax, the unit arrived within a couple of days of ordering. We were fortunate to buy it "on sale" and so were very happy with the price. We use it as a backup to supply outages, and it's excellent for this purpose.”
Large Generators (3,500W+) for Powering Everything
High-capacity generators like the Gentrax GTX6600 Inverter Generator eliminate all compromise, enabling simultaneous operation of large rooftop air conditioners, multiple kitchen appliances, entertainment systems, and additional accessories without concern for overload.
