How to Pick the Best 50 amp Generator for Your RV

With RVs getting more and more appliances on board you are more likely to have a 50 amp RV than a 30 amp RV nowadays.

Unfortunately, most RV parks still have 30 amp power hookups. This means that for you to run your RV fully you’ll need a generator to power your 50 amp RV.

So, for a 50 amp RV you will need a generator that can give at least 4,000 watts, and a maximum of 6,000 watts. Anything over 6,000 watts is a waste of energy, fuel, and money for a 50 amp RV.

For a more accurate wattage requirement, you will need to add up the wattage of all your appliances in your RV. I have a table in the article below to help with that.

I have researched the market to find the best generators for a 50 amp RV, here are the best ones.

The COsense detector that is built in will sense when the carbon monoxide reaches dangerous levels and shuts down the engine automatically.

This feature is especially useful if you will be running the generator in an enclosed space, even with an open window or door the carbon monoxide can build up.

This feature does have it’s downside though, even when you have set the generator up correctly the wind can blow the exhaust fumes towards the sensor and the engine will shut down. Just bear this in mind if the generator keeps turning off and you don’t know why.

How to Pick the Best 50 amp Generator for your RV – Buying Guide

Most RVs will come with a generator installed, which is great. However, you might find yourself needing to replace it or get a backup generator. 

I’d always recommend having a backup generator just in case, especially if you go boondocking or wild camping.

Follow this buying guide so you pick the best 50 amp generator for your RV. the most important things to consider when buying a generator are:

Generator Wattage

Generator wattage is an important factor to choosing the right generator. You want to make sure that there is enough wattage to power your appliances but not so much that it’s wasted.

To work out the maximum wattage needed for a 50 amp RV you can use the following equation:

Amps x Volts = Watts


50 Amps x 120 Volts = 6,000 watts

This means you will need a generator capable of 6,000 watts maximum, there is no point buying a more expensive generator capable of 7,000 watts because the extra watts will be wasted.

So, for a 50 amp RV a 6,000 watt generator is more than enough to power your appliances, you could even opt for generators with a lesser wattage.

As you can see from this table from RV Tech Library, a lot of appliances require more watts to start up and then run on a lower wattage.

Start up watts is the amount of power an appliance needs to start, and the running watts is the amount of power it draws once it’s on.

ApplianceStart Up (Watts)Running (Watts)
Air Conditioner (each)1400-20001700
Battery ChargerUp to 2,0001000

Crock Pot230230
Satellite Dish and Receiver200200
Heating Pad6060

If you want a more accurate wattage for your RV then you will need to break it down by each appliance. 

Add up the starting watts for each appliance in your RV to determine the wattage requirement of your generator. 

This will still be ample for your needs because you’re not going to be turning on every appliance in your RV at the same time.

It’s also a good exercise to know the running watts of your appliance so you have a better idea of how much energy they are using. Turning appliances off when not in use can save you a lot of fuel.

Noise Level

The noise level of your generator is important, whilst you might not think so at the time of purchasing a noisy generator will quickly get on your nerves, not to mention your RV neighbors.

Luckily a generator for a 50 amp RV is naturally going to be on the quieter side, most generators in this range produce between 55 and 70 decibels when running. Try to aim for the lower end of this scale.

For reference, 70 decibels is the equivalent of a vacuum cleaner or toilet flushing, so it is on the louder end of the scale. On the other end of the scale, 55 decibels is the equivalent of an electric toothbrush or coffee percolator.


Obviously when buying anything for your RV portability and weight are important considerations. 

Unfortunately 50 amp generators are on the heavier side at about 100lbs, make sure that you buy one with never-flat wheels and a collapsible handle. This will make it slightly easier to move but it’s still likely a two person job.

You will need to be able to move the generator easily, as they are not the lightest bit of kit in your RV you could consider two smaller ones. This could save on fuel (and noise) if you find you only need the second one occasionally.

Parallel Capability

Parallel capability is another factor you can consider for your generator, it is where you can link two generators together with a special cable. This gives you the option for more power output if you need it.

For example if you have a 2,000W generator powering your RV but you want to then use the microwave oven or AC then you can hook up a second generator to provide the extra wattage needed.

This is definitely something to consider, especially  if you are planning on adding more appliances to your RV.

You will have to also purchase an inverter generator parallel cable to be able to do this.

Generator Fuel Type

The fuel your generator uses is another factor to consider, you want to select a generator that has a fuel that’s compatible with your needs.

The three main fuel types that all generators use are diesel, propane and gasoline.

Diesel generators could be a good idea if your RV runs on diesel. These are also the highest powered generators.

If your RV runs on gas then a gas powered generator will make sense for you. It’s easy to get hold of and gas generators are usually the most economical.

Propane does have a longer shelf life and is better for the environment than diesel and gasoline, so if you are environmentally conscious then you might want to opt for a propane powered generator.

There are also dual fuel generators available that usually run on gasoline and propane. Dual fuel generators are a good option for boondocking, you’ll be less likely to run out of fuel if you have a backup propane tank. They are more expensive though.

Fuel Efficiency

Fuel isn’t cheap, and can be hard to get hold of if you are camping in the middle of nowhere. You want to make sure that the generator you buy has an economy mode feature.

The economy mode feature means that your generator will use initiative and only output the power that is needed at the time.

This will save you a lot of fuel and money in the long run.

It also makes the generator quieter, as it will lower the engine to match the output. This also extends the life of the generator as it’s not operating at maximum all the time.


As with everything you buy, you should have a budget in mind. Generators are expensive, luckily 50 amp generators are on the cheaper end of the scale, but this can still set you back between $750 and $1,500.

Make sure you know which features are the most important to you and which ones you don’t need and save some money on. 

RV Outlet Plug

Check that the generator has a 50 amp RV outlet. I have bought a generator before, ready to hook up and then realized that I need to purchase an adapter for it. 

Save yourself the frustration by checking there is an RV outlet on the generator, or that you have the adapter.

50 Amp Generator FAQs

What Size Generator For 50 Amp RV?

For a 50 amp RV you will need a generator that is between 4,000W and 6,000W, this should be enough to power all your appliances. You don’t need a generator over 6,000 watts as the extra power will be wasted.

What is a 50 Amp Service?

In an RV a 50 amp service refers to the amount of electrical current that is needed to power essential appliances and devices on your rig.

A 50 amp service means that your RV won’t receive more power than 6,000 watts (50 Amps x 120 Volts = 6,000 watts). A 50 amp service is found in RVs with lower load requirements.

A 50 amp plug is three pronged, it includes a 120 volt wire, a neutral wire and a ground wire.

Can I run a 50 amp RV on a 30 amp generator?

Yes, you can run a 50 amp RV on a 30 amp generator. You will need a 50 amp (female) to 30 amp (male) adapter.

The adapter you will need is usually called the “dogbone” because of its shape. Once you have the adapter just plug it into the power source and plug your RV into the other end.

Is a 4000 watt generator enough for RV?

Yes, a 4,000 watt generator is enough to power most RVs. Most modern RVs are 50 amp and they need generators in the range of 4,000 watts to 6,000 watts.

You will be able to use all of your appliances in the RV using a 4,000 watt generator. Just be aware that starting up appliances tends to use more power than running them, so try not to turn everything on at the same time.
