Why do I need a portable generator for my RV?

The days of ‘roughing it’ over a campfire with nothing but stories and songs to keep us entertained are a thing of the past for many campers. With RVs increasingly being fitted with all the mod-cons, and our own thirst for modern technology, we need an energy source to keep our appliances running.
Having a solar energy system installed in your RV is a great way to ensure you can access this power when off-grid. However, when this solar system is unable to sufficiently provide the energy you need (perhaps if you have consistently cloudy days on your camping trip) it is a good idea to invest in a portable generator for your RV.
Portable generators provide electricity by a motor that is powered by fuel (gasoline, diesel or propane). Due to being ‘portable’, they are designed so that you can store them easily in your RV, and then use them when you need the power.
Some portable generators for your RV come with an inbuilt inverter, this is so that your appliances are protected from damaging power surges, caused by harmonic distortion, by producing pure ‘sine wave’ power. A portable generator with an inverter is a good idea if you are planning on charging high-quality electronic devices, such as a laptop and smartphones. This is less of a necessity if you will just be using your portable generator for the essentials such as lighting and your kettle.

How many watts do I need in my portable generator for my RV?

As with all power-giving devices, the best size portable generator for your RV will be dependent on the electronic appliances you want to use. The portable generators on the market are rated in watts (W) and range from 800W at the lower end and 12,000W at the higher end.
If you only require the bare necessities on a short camping trip (such as lighting and boosts of your smartphone) then a 1000W portable generator will sufficiently cater to your onboard RV power needs.
However, if you are wanting to power up an air conditioning system in the summer, or heating in the winter and you are partial to a cold beverage from your inbuilt refrigerator then you will need a portable generator with a higher wattage. A 3000W portable generator will be able to cater to these needs.
It is always a good idea to go for a portable generator with a slightly higher wattage than you expect to need so that you are not caught short and can enjoy your RV trip with all of your electronic essentials.

What do the differences in fuel type mean in portable generators?

You will notice when looking at portable generators for your RV that they are powered by different fuel types. This is an important consideration when selecting the best portable generator for your RV as you need to think about the availability of the fuel type in relation to where you will be using the generator, as well as how long you are likely to need to store the generator fully fuelled up.
The most common (and cheapest) choice of portable generators are those fuelled by gas. These have the convenience of being the same fuel type as your RV, so when it comes to re-filling you only have to think about the one type of fuel for both your RVs gas tank and your portable generators.
If you are likely to be storing your portable generator for a while and want to keep it fully fuelled, then a propane powered generator may be the best choice for you. Out of all of the fuel types, this has the longest sell-by date and won’t go stale like other fuels would. It also has the advantage of making the generator run less noisily than others, so a good choice for those with sensitive ears. The disadvantage is that propane produces less power and isn’t as readily available as other fuel types, so make sure you are confident that you can purchase this fuel easily before you invest in this type of portable generator.
As with gas, a diesel-powered portable generator is a smart choice if your RV runs on this fuel type – it helps to avoid confusion when topping up your tanks. Diesel powered generators are rated highly for their efficiency, yet the downside is that they can be a noisy and less environmentally friendly option.

How long will the portable generator be able to run for in my RV?

Now we have distinguished the different types of fuel types, let’s look at how long you can expect your portable generator to run for. The last thing you want is to run out of power when you are miles from a fuel source so careful consideration of how long you need the portable generator to last for is important. High-quality portable generators should have a running time of around eight hours, so you should aim for a model that promises to deliver this efficiency.
Another thing to look out for are portable generators that are able to react to the electrical devices you are choosing to power; some quality generators are able to reduce their engine speed if you are only requiring power for small devices and therefore uses less fuel than if it was constantly running at full capacity. This means that fuel is not wasted unnecessary and makes for a very efficient system.

Are some portable generators noisier than others?

In short, yes. Generators are well known for their annoying and distracting noise level, however, over the years reducing the noise level of generators has been a key consideration for developers in an attempt to both reduce noise pollution and to keep their customers happy.
So, if you are driven to distraction by a constant relentless buzz or really want to be at one in the serenity of the outdoors, it is a worthwhile consideration to choose a portable generator that promises to keep the noise down. Look out for generators that have a lower decibel rating (measured in dBa), with those rated under sixty dBa having the most tolerable noise level. In addition, portable generators that have an inbuilt inverter are quieter than those without – another virtue of this type of product.
For the power hungry, however, you need to weigh up your noise tolerance levels against your power needs as with more power inevitably comes more noise. If you really need the power and can’t stand the noise, an alternative option is to run two smaller portable generators in parallel.

What about the physical size of the portable generator?

Portable generators come in different shapes and sizes, with some heavier than others. This is an essential consideration as the size of your RV will determine the weight and dimensions of the portable generator it can accommodate. You also need to think about what you yourself can physically carry, and what is realistic to keep your back in a healthy condition!
Inevitably, portable generators that are more powerful will be larger in size and heavier to carry. However, a lot of portable generators come with wheels which help with manoeuvring and handling – look out for this design feature on the heavier models. You also need to think about the impact of the weight of the generator on your fuel consumption. It is, therefore, pivotal that you check the weight of the portable generator before purchasing.

Are portable generator environmentally friendly?

If you are using a portable generator as a back-up should your solar energy system be falling short of the necessary energy, you will no doubt be environmentally conscious and be concerned about how the use of a portable generator for your RV will affect your green credentials.
Being fuelled from a non-renewable energy source, portable generators are, of course, not as green as your solar energy system. However, there are options you can make to keep your carbon footprint down. Look for a portable generator that has a high-efficiency rating, this will mean your fuel consumption will be lower. Propane is the most environmentally friendly fuel choice so you could opt for a generator that uses this fuel type. Also look out for portable generators that have Environmental Protection Agency (EPA) approval.


With the vast array of portable generators for RVs on the market, it is easy to be daunted about where to start with choosing the best option for you. This article has highlighted some of the best products currently out there to make this task that bit easier.
Make sure you think about how much power you are going to need to help you select the correct wattage rating. Fuel source is also an important consideration, and if you are only going to be using your portable generator as a back up should your solar energy supplies fall short then propane would be a good option as this has a long storage life and is also safe to store.
Portable generators come in different shapes and sizes, with some more easily portable than others, so it is important to consider the best fit for your RV. You also need to consider the noise levels of the generator and whether or not it is fitted with an inverter as these are important factors that will contribute to your satisfaction with the product.
