Generators for RV campers: what are they?

An RV generator is a smaller variation of the popular portable generator commonly used as household electric appliances during power cut-outs or for outdoor events and as emergency Back-Ups.

RV generators are specifically designed to provide power to all your appliances and accessories in your motor home; you just have to pop an RV generator in your gear compartment!

Advantages and Disadvantages of having an RV Generator


Recreational Vehicles are not just simple camping gears, instead, modern RVs are installed with all the luxury appliances and electronic gadgets that sometimes even our houses don't offer. To name a few, in your RV van you can:

  • Be full air-conditioned,
  • Watch Television,
  • Cook food, make tea,
  • Connect your laptop and PC?s for important and necessary work,
  • Listen to your famous podcasts, (and while driving this becomes essential,)
  • Your little ones can play all kinds of virtual games,
  • And many more.

And for all these leisure activities you need power, in other words, Electricity. If you plug in all these appliances to your RV battery, I doubt your RV will be able to travel even a few kilometers.

You must be wondering why RV?s unit batteries can?t handle it all. Well, an RV?s battery mostly powers some basic cooking gears and overall truck?s lighting appliances.

That?s all, and for everything else, you will need other power sources (Most RVs don?t even recommend using other leisure appliances, on RV?s battery).

Just imagine yourself camping at a faraway place (which is very hot or cold), where you are left with raw, uncooked food, and adding to your misery you have to submit an urgent report about your work progress.

You will have to rush to a nearby RV campsite, which must have outlets of power, and there you have a stand in a queue waiting for your turn to charge RV?s battery!

Isn?t it better to leave all this inconvenience and create your own electricity?


Although there are some other sides or cons of owning a battery too, and I will not leave you unaware of them.

  • The batteries come at a cost and you have to pay a price for portable RV batteries. (RV Generators are a bit expensive than portable generators)
  • You will need to carry three or more gallons of gas to run the system.

Quick Tip - If possible buy a propane fuel system and not a diesel-powered system because they are not so common and secondly they increase the overall cost.

  • Most RV generators are portable generators, which make them an easy target for thieves and robbers.

Quick Tip - Keep your generators protected by covering them in a rolling bag and chain them in your vans.

Overall there are more pros than cons, and with all the cons, there is some available solution.

Choosing the right generator for travel trailer camping

A wide variety of RV generators is available in the market, but before you start purchasing look for these two significant aspects.

SIZE (Watts) Before purchasing a generator, consider the best fit (according to the size) - for your RV. The size of RV Generators depends on the size of your vehicle.

Related: Best RV Solar Kit, an eco-friendly way of enjoying energy!

Here is a simple math trick to determine the best size for your vehicle.

Count the number of appliances that run on 120 volts, and find out how many amps they require, (both this information will be available on the back of your appliances).

Now calculate the number of Watts by this simple formula:

Watts = Amps x Volts

This simple exercise will provide you the - minimum wattage you require when you start looking for an RV generator.

Remember - Always buy a higher Watt generator than your minimum requirement, because generators do not provide the full value of Watts as promised.

Note - Air conditioners will have a higher starting voltage in comparison to their running voltage. So calculate starting wattage for air conditioner, and running wattage for all other appliances.

FUEL  ? The second important aspect to consider is Fuel.

You have three options for fuel - Diesel, Gas, Propane.

Diesel powered Generators are costly and uncommon. Even carrying them is risky.

Gas --powered Generators are very economical, and carrying them reduces the weight as well as other flammable hazards.

Propane is the greenest fuel due to its cleaner emissions. So if you are passionate about environment go for Propane-powered Generators. They are quieter too is compared to both the above fuels.

However consider this fact too - propane reduces the generator?s power by approximately 10%, and secondly, you need to carry an oversize tank for fuel storage.

Diesel vs Propane vs Gas Generators For RVs, Campers, and Travel Trailers

Deciding what kind of generator could be best for your needs can be a little confusing sometimes. If you have any questions or doubts, we?re here to break down the properties of diesel, propane, and gas generators for you.

Choosing the right fuel depends on how you want the generator to work.

If you want your generator to work in a quiet environment, be eco-friendly, have an unlimited fuel source, and you have access to natural gas, you can choose to use a natural gas generator.

Another distinct feature of natural gas, when compared to diesel and propane, is that it leaves no residue. This means that your generator will always be clean.

The drawback of natural gas is that its power output is lower than the power output produced by diesel and propane generators. The costs to set up natural gas is also relatively higher. The natural life expectancy of a natural gas generator is also shorter as well. 

Propane generators are quite similar to natural gas generators. They are easily available, meaning you can get easy access to them whenever you need them. Propane generators also produce little-to-no noise while functioning.

The lower emission of residue can be a good factor to consider when looking at how effective it works as well.

The disadvantage of using propane is also similar to natural gas. It’s expensive to set up, which means it’s more expensive than diesel. Compared to diesel, it’s less efficient and doesn’t have as long of a life expectancy.

Diesel is the most common form of fuel for vehicles. Being the least expensive and the most effective, diesel generators are in great demand, which is not surprising. You face less problems with it compared to propane and gas.

When it comes to noise, diesel generators generate the loudest noise. Another drawback is that they emit pollutants at a huge rate.

Diesel generators cannot be used to their full capacity and the diesel leakage could damage various parts of the generator, making it ineffective to use sometimes.

While it can be a little challenging to choose the right generator for your needs, the process can be simplified by studying your wants and needs. Gas and propane are more expensive, but they are also less efficient than diesel. The oil leakage and congestion of grease combined with the loud noises can be a massive drawback. So, the perfect generator is yours to decide.

Understanding How an RV Generator works

Once you have selected the best fit, it is highly recommended that you know the basics of your machine. You will never want to carry along a mechanic on your family outing.

And in far remote places it becomes difficult to find one, so it is always handy to know a bit about your purchase.

There are four functional parts of any Generator.

  1. Motor
  2. Fuel system
  3. Motor Starter
  4. an electric power generator


To keep the motor run smoothly you need to see that it?s properly lubricated with oil as mechanical parts rub against each other causing friction and heat.

Also, check that the motor is not overheated.

Fuel System

A fuel system is where the fuel is stored. This part does not need much service but occasionally you need to clean it and some of its parts, like the fuel filter and the carburetor.

If the fuel system gets dirty or gets blocked then the motor will work slow.

Motor Starter

The motor of a Generator goes through the firing of several cylinders for its start. Once started, it will run on its own.

Check for the wires (which connect the motor and the cylinders) so that none of them are short and are properly connected.

Secondly, listen to the sound when you start the motor. If it makes a weird sound, then there is some problem with your starter.

Power Generator

This is the part that actually converts chemical fuel and mechanical energy into electricity.

The design is the same as other generators. A solenoid rotates in a magnetic field, producing electricity.

Generally, there are many fewer chances of shutting down of this part, but if it does you should let a trained generator mechanic to handle the problem.

Maintaining your RV Generator

Generators are electronic devices, and they need little care. Proper maintenance tips – assure generators long life, and cuts off other unnecessary expenses. Here are some of the vital maintenance tips:

  • Keep the Generator clean.
  • Protect it against dust
  • Turn off non-utility appliances when traveling in extreme weather conditions. If the temperature rises above 85 degrees Fahrenheit (29.4 Celsius) the generator will also lose 1% of its power (for every 10 degrees Fahrenheit (5.5 Celsius) rise).
  • While traveling in high altitudes make sure to carry along more fuel, because for every 1000 ft (above 1500ft) your generator will lose 3.5% of its power.
  • Check the exhaust for any leaks prior to your journey. Remember fumes can cause burns and fires.
  • Switch off the machine when not in use especially at night. It will save fuel.
  • Service your generator regularly, and do not forget the servicing dates, (as per the manual) otherwise the manufacturer?s warranty may become invalid.
  • If you buy a new generator run it for a few hours. The operator manual will tell you how long you should test-run it.

Today these machines have become very common. And because of them, RV trips are also becoming the number one choice for family outings.

In-fact RV Generators are the reason that so many people are now happily enjoying the RV lifestyle and why so many “RV camps” are appearing in scenic and popular tourist locations.

If you get a reliable generator of the right size and power for your needs you will have carefree trips without any worries.

Above I have listed some of the best Generators for your RVs and some built in RV generator. If you like one of them, then without wasting any time hurry up and buy your own RV Generator and fly off to a nice place for an enjoyable vacation.

Enjoy and have fun!
