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 can be an issue. They're also more compact and lightweight, which makes them easy to store and transport. If you're looking for the best generator for a caravan, an inverter generator is often the top recommendation thanks to its quiet operation, efficiency, and ability to protect your gear.
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
-
Phone Charger = 5W
-
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, the Yamaha 2000W Silent Inverter Generator, EF2000iS is one of the quietest generators available, with a noise level of 51.5 dBA (1/4 load) / 61 dBA (full load).
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.

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. 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?

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.
Yamaha Vs Gentrax

Recommend right size generator.
Hello Rob, thanks for the informative article. I have a small caravan on order, and it will have Houghton Belaire HB 2400 air conditioner and was wondering if the Yamaha 2200W Inverter Generator Pack, EF2200IS would be the right size. Will probably be only using the AC with a small 12v tv and the Dometic NRX130-RHH fridge at the same time. Thanks for any advice. IanBy: Ian Thomas on 16 July 2024
www.caravanrvcamping.com.au Response
Hi Ian, the Yamaha 2200w will power this air conditioner no problems at all. Remember to be mindful of what are you running at the same time. ie; don't boil the kettle and use the air conditioner at the same time.
Best generator for caravan
Hi can you recommend a generator that will power our 2 berth caravan, it has an electric water pump that doesn’t get enough power from the aux battery.. apart from the pump we power 4 internal lights and have a TV. We would also need to be able to charge our phones up. I was thinking of just plugging the caravan’s Mains lead into the generator - avoiding the aux battery completely. Can you advise pleaseBy: Steve Bevers on 14 July 2024
www.caravanrvcamping.com.au Response
Hi Steve, it sounds like you don't have any large power needs which means you don't need to have a larger generator. Any inverter generator between 1-2kva. If you are wanting to run more things like toaster/kettle or roof top air conditioner you will need to step up into 2.4-3kva. Please feel free to give us a call on 1800 787 278 and we can assist in sending you options that will suit
Inverter Generator Suitable for Starting/Running a
Hi, I am purchasing a new motorhome which is expected to be delivered in August 2024. In the meantime I am looking to buy an inverter generator that is capable of running a Harrier Plus air conditioner and other appliances including a microwave. Are you able to suggest the best brand and power output that will be needed to run this equipment? One unit that I have been considering is the Outbax - Gentrax 3.5kw Max3.2kw (Rated Remote Start Pure Sine Wave) petrol inverter camping generator. What do you think?By: David Ramsden on 27 February 2024
www.caravanrvcamping.com.au Response
Hi David, I will reach out to you via email. For reference the generator you mentioned I feel is too large for your needs and is quite heavy when weight is so important in the caravan. I would check out the Maxwatt 2800W Petrol Inverter Generator with Electric Start, it is 10kg lighter and will easily run the Air Conditioner. Also check out the Cromtech Outback Inverter Generator 2.4kw, another ripper for this application.

Generator sizing - Houghton Belaire 3400 AC
Hi Wonder if you can assist. We have a 19.6ft caravan with a Houghton Belaire 3400 air conditioner, 3000w inverter, and a Honda EU22i generator. However, the Gen will not run the AC even with fridge on Gas and everything else (power wise) turned off. Apparently the problem appears to be part of the Gen power is being used to recharge/top-up the batteries (2 x 200Ah lithium with 510Ah solar panels). All runs OK when plugged into mains 240v. So question - will a larger Gen (eg. Cromtech Outback 4500w) be likely to overcome the inadequacy of the current Gen. Advice/comments would be appreciated.By: Rob Baird on 04 February 2024
www.caravanrvcamping.com.au Response
While the Honda EU22i generator is a very robust and powerful unit, you may need to increase your overall running watts to keep you going. The Cromtech 4500w is a great unit that is very popular for people using more than 2400 watts continuously. Maxwatt is also another brand to look out for as well. These both are backed with a 2 year warranty and offer a great affordable option for powering your caravan off grid. Feel free to reach out to us on 1800 787 278 and discuss your power needs

Generator for aircon
Hi. I have a Harrier Plus HP36H401R1 aircon. Looking for a generator to run this efficiently plus maybe the microwave at the same time. Thanks so much.By: Jill Daly on 16 November 2023
www.caravanrvcamping.com.au Response
Hi Jill, having a generator to run your Air Con while caravanning is a perfect idea. You would be best to aim for a generator over 2.4Kva if you wish to have other appliances running. Keeping in mind when the Air Conditioner drops below it's set temperature and the compressor kicks in or when first turning the Air Con on it is best not to have anything running at the same time.
