What Is A Caravan Generator?

 A caravan generator is a model of generator that is used to provide you with a reliable source of electricity to power your onboard appliances. This will be the same type of generator that is used for outdoor events, campsites and in the construction industry.

A caravan generator will make your life considerably easier because you won’t have anything stopping you from turning on your favourite appliances as you’ll now have a reliable power source. 

Although most caravan parks will have a power hook up, there can often be usage restrictions and reliability issues. So, it’s always ideal to have your own, especially if you tend to caravan away from caravan parks.

The best caravan generator will have AC outlets so you can easily plug in your traditional appliances such as fridge, microwave, hairdryers etc.

How It Works

Generators tend to all work in the same consistent way which is through the use of inbuilt motor that’s fuelled by propane, diesel, or unleaded gas. The fuel undergoes combustion which generates power to run the motor then.

This is a simplistic explanation of the process, but some models will be more complex than others depending on the brand and overall quality. For example, some models will only have a single motor, whereas others will have multiple, which will affect it’s power output and efficiency.

Popular Types of Caravan Generators

Diesel Generators

Diesel generators are the traditional type of generators that are usually noisier than alternative types of fuel. Still, it has burns much more efficiently, which means that you get more for your money each time you refill.

Gas Generators 

Gas generators are the most common fuel type for a generator, especially for caravan use. Gas can be on the costlier side; however, this will depend on how quickly you consume fuel. Also gas is more readily available, so you’ll find it easier to find a station that has it for sale which can be difficult for other types of fuel especially when you’re outside of cities or towns.

Propane Generators

Propane generators are the up and coming type of caravan generators which means that their availability is also increasing, giving you a greater choice of models. Propane is not only extremely efficient, but it’s also environmentally friendly while also being quiet in operation, giving you a high-quality product.

How To Look After Your Portable Generator

Although buying the best caravan generator is important, you also need to ensure that you look after it to prolong it’s life meaning that you’ll need to replace it less often.

Regular Servicing

Your generator could be developing faults without you realising if it’s happening inside the engine. If you have regular services, then you can spot developing issues such as general wear and tear, which can develop into more serious problems.

The best caravan generators will come supplied with service guides that give you information about how to perform regular service. 

Safe Storage

Even when not in use generators can be damaged due to moisture and other weather conditions. It’s important that when it’s not being used, it’s stored in a dry, cool place. Also, before you store it away, you should gently wipe down its surfaces. 

Additionally, if you’re storing it away for the long winter months, then you should ensure it has a full tank and change its oil so when you return to use it in several months, it will still be in great running condition.


For generators and other types of engines, oil is a vital product that ensures for the smooth running of the engine which not only keeps it running efficiently but also prolongs its life. This is similar to your car engine that also needs to be well lubricated, which also reduces the amount of noise it makes.

Regular Use

To make sure your generator runs smoothly, you need to use it regularly as this also will show you any issues before they develop into more harder to fix problems. Even if your generator is stored away, then you should still run it regularly.

Never Use Old Fuel

It may be tempting to use old fuel that’s been sitting in your engine all winter to save a bit of money, but it’s important always to use fresh fuel because old fuel is less efficient and can also cause damage to some models of the generator. 

Buying A Generator For A Caravan

The factors you need to consider are:

Power Output

One of the main factors is the amount of power that your generator can produce. The main goal is to get the best generator for your needs and power requirements so that you have enough power for your appliances.

For example, if you have a high power consuming appliances such as an air conditioning unit or Heater, then you’ll need to select a generator that has a higher power output to be able to meet your needs.


The overall build of the generator is essential, and each manufacturer will list the dimensions of the unit. Ideally, you should choose one that is not only small in dimensions but also lightweight so you can easily move it from one position to another.

Although size and weight are crucial to understanding, you should also investigate the overall build quality as to how durable it is. It may spend the majority of its time outdoors, so it will need to be able to withstand all types of weather conditions from high-temperature UV rays to heavy wind.

Operating Noise

It’s all well and good to buy the generator with the most powerful output, but you also need to understand how loud it is. This is very important, especially if you plant o have it running while you sleep through the night.

Luckily, manufacturers see noise as a key feature, and there are quiet generators which also lowers the risk of disturbing your neighbours. At the same time, many caravan parks have limits on the amount of noise you can make. An easy way to know how loud a generator will be is by its dB level.

Ease of Installation

Now we all like to think that we’re DIY professionals, but you should consider how easy your desired generator is to set up, not only when you first get it but also every time it’s time to be used with your caravan.

The last thing you want to do is realise that it takes you an hour to set up each time which can be incredibly frustrating especially if you arrive at your caravan site at night or in the rain.

The best caravan generators will be simple to set up, have easy to follow instructions and may also have additional support via phone or email.

Fuel Consumption

Fuel consumption is what will hit your bank balance the most once you’ve paid for your generator, so you must understand how often you’ll need to add fuel to the generator.

This is also important, so if your caravan trip is far from a local petrol station, then you can easily plan how much fuel you’ll need to take with you. Some models also have low power or eco modes which help to conserve fuel. A pure sine wave inverter is a more sustainable power source, whilst solar panels are significantly more eco-friendly.


You need to understand how portable your desired caravan generator will be. A portable generator will mean that you can easily move it from position to position whereas a more permanent solution will need to be attached your caravan at all times. A portable generator will often be smaller in size, meaning that when you pack it away, it will require less storage space. 

A portable generator may also have easy to carry handles which not only makes it easier to carry but also to manoeuvre it into position. 


No matter what product you’re buying, there will be a maximum amount that you’re willing to spend. Because there is a range of generator brands, this means that there’s not only a huge choice but also many different price points which can make the buying decision even more difficult.

You need to decide what features are most important to you and the maximum amount you’re willing to spend. This will also make it easier to choose because this will limit the number of options available to you.


As with all types of products, there is a chance that a fault could develop. This can be limited by choosing a high-quality product, but the risk is still there. For this reason, you should see if your desired generator is supplied with a warranty which will provide you with protection if a defect occurs, which affects its operation.

Warranty lengths will vary depending on the brand of the generator and will generally range from six months to a lifetime. Of course, the longer the warranty, the better the protection giving you more peace of mind that you’re buying a product that the manufacturer believes in.
