Size of Generator

When it comes to generators, size does matter. The size of the generator you need will depend on a few factors, such as the type of RV you have, the number of appliances you plan to run, and the length of time you need to run them.

For example, a small travel trailer might only require a 2000-watt generator, while a larger RV could need up to a 10000-watt generator.

The good news is that there are many different sizes and types of generators on the market, so you should be able to find one that meets your needs. However, before you purchase a generator, it is important to understand how much power you will need.

How to Size a Generator

When sizing a generator, the first thing you need to do is determine the wattage of the appliances and devices you plan to run. This can be done by looking at the appliance’s nameplate or the owner’s manual.

Once you have the wattage of all the appliances and devices, add them up to determine the total wattage you need. For example, if you have a fridge that uses 500 watts, a TV that uses 200 watts, and a microwave that uses 1000 watts, your total wattage would be 1700 watts.

However, this is not the only factor you need to consider when sizing a generator. You also need to take into account the “surge wattage” or “peak wattage” of your appliances.

The surge wattage is the amount of power an appliance needs to start up. For example, a fridge might use 1000 watts to start up, but only 500 watts to run. This is why it is important to consider the surge wattage when sizing a generator, as you will need a generator that can handle the initial surge.

Additionally, some appliances, such as air conditioners, need more power when they are first turned on. This is called the “peak wattage”.

Once you have considered the surge and peak wattages of your appliances, you should add at least 25% to your total wattage. This will give you a bit of a buffer and ensure that your generator can handle everything you need it to.

How Much Power Do You Really Need In A Travel Trailer?

If you have ever been in an RV with a generator running, you know that they can be quite noisy. But just how much power do you need to run a travel trailer?

The answer may surprise you.

Most people believe that they need a large generator in order to power their travel trailer. However, this is not necessarily the case.

In fact, you may be able to get away with a smaller generator than you think. So, what size generator for travel trailers is right for you?

It really depends on a few factors, such as the size of your travel trailer, the number of people who will be using it, and the types of appliances and electronics that you plan on using.

Here is a quick rundown of what you need to consider:

Travel Trailer Generator Size

One of the biggest factors to consider is the size of your travel trailer.

The larger the travel trailer, the more power you will need to run all of the appliances and electronics inside.

However, if you have a smaller travel trailer, you may be able to get away with a less powerful generator.

The Number of People Who Will Be Using the Travel Trailer

Another factor to consider is the number of people who will be using the travel trailer.

If there will be more people using it, you will need a more powerful generator to accommodate everyone.

However, if there will only be a few people using it, you may be able to get away with a smaller generator.


When it comes time to purchase a generator for your travel trailer, there are many factors you need to take into account. The size of the generator is one of the most important things to consider.

If you choose a generator that is too small, it may not be able to power all of your appliances or electronics. If you choose a generator that is too large, it may be more than you need and could end up costing you more in the long run.

By considering the size of your travel trailer and what appliances and electronics you plan to use while on the road, you can select the perfect generator for your needs.
