Planning to head off-grid or power up your campsite? A reliable generator can make all the difference. In this Complete Buyer’s Guide to Camping & Caravan Generators, we’ll help you find the best generator for your caravan and camping setup—whether you're running a fridge, lights, or air conditioner. From understanding your power needs to choosing the right fuel type and size, this guide will walk you through everything you need to know. If you're searching for the best caravan generator or just want to explore your options for a caravan generator, you're in the right place. Let’s dive in!
Inverter Camping & Caravan Generators
When it comes to camping and caravan power, inverter generators are the most popular choice—and for good reason. These generators produce clean, stable power that's safe for sensitive electronics like laptops, TVs, and mobile devices. Unlike traditional generators, inverter models adjust their engine speed based on power demand, making them more fuel-efficient and much quieter—ideal for campsites or caravan parks where noise is a concern. Most camping inverter generators run on petrol, which is a practical choice because petrol is readily available across Australia and you can easily top up the fuel to keep your generator running longer. However, the downsides include the need to carry and store petrol, and some campers prefer to avoid petrol fumes in close quarters. That said, inverter generators remain a favourite thanks to their quiet operation, portability, and ability to protect your gear—making them one of the best options for powering your caravan off-grid.
What Generator Size Do You Need for Camping?
The right generator size for your camping setup depends entirely on what appliances or devices you plan to run. Each item has a power requirement, known as its load, and some camping appliances draw more power than others—especially those with heating elements or motors like microwaves, air conditioners, and washing machines.
Start by making a list of the appliances you want to use and check their wattage. This will help you understand the total power load your generator needs to handle. Keep in mind that while many devices can be powered one at a time, running several simultaneously will require a larger generator.
As a general guide, a 2000–2400W inverter generator is suitable for most caravan setups. This size can handle essentials like lights, chargers, and a fridge, and still give you enough capacity to run higher-draw appliances individually, such as a microwave or washing machine.
Average Appliance Watts:
-
Battery Charger = 350W (20A Battery Charger), 1050W (60A Battery Charger)
-
Washing Machine = 1200W – 1600W
-
Microwave = 900W - 2200W (try and choose a low wattage caravan model)
-
Laptop = 50W-100W
-
Phone Charger = 5W-20W
-
TV = 200W
How Do Portable Camping Generator Watts Work?
Generators are rated in watts (W) or kilowatts (kW), which tell you how much electrical power they can produce. The higher the wattage, the more appliances your generator can run. But it's important to understand the two different types of wattage ratings:
-
Continuous Output (Running Watts): This is the maximum amount of power the generator can supply on an ongoing basis. It’s the key number to focus on when choosing your generator. Make sure your total appliance load stays under this figure.
-
Peak Output (Starting Watts): This is the short burst of extra power a generator can produce to start appliances with motors or compressors—like air conditioners, washing machines, or power tools. These items often require more power to start than they do to keep running.
TIP: Sometimes a generator will be rated in KVA. Always look to the specifications for the real power output that will be rated in kW or Watts.
What to Consider When Choosing the Best Camping Generator
Choosing the best generator for caravan or camping use means looking beyond just power output. You’ll want something that fits your travel style, keeps your gear running smoothly, and won’t disturb the peace of your surroundings. Here are the key features to look for:
1. Run Time
A generator’s run time determines how long it can operate on a full tank of fuel. When you’re off-grid, the last thing you want is for the power to cut out in the middle of the night—leaving your fridge warm or your devices dead. Look for a generator that can comfortably run for at least 8 hours, especially if you’ll be using it overnight. This helps reduce the need to refuel frequently and keeps your setup running reliably while you relax.
2. Noise Levels
Noise is a big deal when camping—both for your own comfort and for keeping fellow campers happy. Generators can range from whisper-quiet to annoyingly loud, so always check the noise rating (measured in decibels or dBA).
Tip: Look for a noise level below 60 dBA for quiet performance.
However, be cautious when comparing models—some manufacturers test noise levels at just ¼ load (light usage), which makes them appear quieter than they really are at full capacity. Always check both ¼ load and full load noise ratings if available.
Inverter generators are typically the quietest option, especially compact, suitcase-style models. For example, Cromtech Outback Platinum 2400W Inverter Generator is one of the quietest generators available, with a noise level of 52db - 59db.
3. Size and Weight
Portability matters when you’re loading up your caravan or 4WD. A large, heavy generator can be awkward to carry and store, especially when space is already tight. That’s why many campers opt for compact, lightweight inverter generators—they’re easier to move around, store neatly in a boot or storage box, and won’t weigh your setup down.
Small generators in the 2000–2400W range strike the perfect balance between portability and performance, making them a favourite among seasoned travellers.
Running an Air Conditioner
If you are planning to run an air conditioner while staying off the grid away from powered sites, then you will need a generator. A good quality 2400W from our website will support the majority of air conditioners available.

The size of generator you need depends on what appliances you want to run. A 2000W to 2400W inverter generator is suitable for most caravan setups, including fridges, TVs, lights, and smaller appliances. If you plan to run an air conditioner or microwave, consider a generator with at least 2400W–3000W capacity.
2. Can I run a caravan air conditioner on a generator?
Yes, but you’ll need a generator with enough power to handle the startup surge of the air conditioner. A 2400W inverter generator is suitable for most modern caravan air cons with a soft start. Always check your air conditioner's specs and choose a generator with pure sine wave output to ensure compatibility.
3. Are inverter generators better for camping?

Mycoolman 3000
Hi, thanks for the article. Will the Yamaha ef2200is run the mycoolman 3000?By: Adrian on 18 January 2025

Hi Adrian, yes the Yamaha will certainly run the MyCoolman Air Con. You will need to mindful of what else you have running off the same power supply.
Best Gene for Caravan AC
Would a Yamaha EF2400IS run a Caravan AC Dometic Freshjet series7 FJX7457HP and say a caravan tv at the same time. Having awareness on continuous input capabilities. Or would you recommend another compatible unit. Also would the theory of turning off the AC during other short use of other electrical items and then turn back on the AC be feasible. Carvan has 2000w inverter with 2 x 240 amp batteriesBy: Malcolm Irwin on 29 December 2024
www.caravanrvcamping.com.au Response
Hi Malcolm, the Yamaha EF2400Is will run the Dometic Freshjet Series 7 Air Conditioner and a caravan TV at the same time. You will need to turn your air conditioner off if you want to use items that have a high watt draw such as anything with a heating element (kettle, toaster etc) The generator needs to be used within its capabilities to maintain a lengthy and reliable life.
