Best Generator for Enclosed Trailer

Whether you permanently live in an enclosed trailer or use it for other purposes like camping, power is the ultimate requirement to stay connected and comfortable.

Buying an enclosed trailer with a built-in generator may be heavy on your pockets. Using a portable generator is the most convenient solution to power up all your necessary appliances like an air conditioner, oven, television, mobile, laptop, etc.

Traverse our reviews of some top generators in the market. We have focused on key aspects of these generators to help you choose the best generator for enclosed trailer.

An informative buying guide will also be here. Without any further due, let’s get started.

Why A Generator Is Necessary for an Enclosed Trailer?

Not all enclosed trailers come with a built-in generator. Even if it comes with one, the output wattage might be lower than the total wattage you need to run all your appliances.

Many of your appliances in an enclosed trailer, like an air conditioner or a microwave oven, will draw a good amount of power from the source. Most built-in generators can’t provide this much power. Even if they can, the price goes higher and higher.

You can solve this issue by buying a portable generator for enclosed trailers. A properly sized generator for enclosed trailers will meet the power needs of all your appliances. So, you don’t need to worry about running your air conditioner at full power on a hot summer day.

These generators are portable so that you can take them anywhere you need. For example, you can carry these generators to your campsite to fire up the microwave or induction cooker to cook your favorite meal.

The versatile usability of generators for enclosed trailers is the main reason behind their popularity. Also, these generators cost less than buying enclosed trailers with built-in generators.

How Many Watt Generator Do You Need for an Enclosed Trailer?

This is a tricky question to answer. Just a random answer might misguide you in choosing the right generator, and you can fall short of power when needed. It is safer to calculate the total wattage all your appliances will need from the generator.

How Many Watt Generator Do You Need for an Enclosed Trailer

Running an air conditioner will take the larger portion of the wattage. And the starting amps might be greater than running amps. Include all appliances and determine how much power they are going to need.

After summing the required wattage, keep a safety margin of about 20%. For example, if you need a 3000W generator, go for a 3600W generator. Keeping this safety margin will ensure all your appliances get enough power. It will also ensure there isn’t much stress on the generator.

Running such a generator with overload for a long time will decrease the efficiency and service life of the generator. So, if you want the full potential of a generator for enclosed trailers, choose wisely.

One more thing, check whether the wattage manufacturer claims is real. Buying a generator from renowned brands will ensure you get the right wattage.

Things To Consider When Buying A Generator For Enclosed Trailer

Though the task of a generator is as simple as delivering enough power for appliances, choosing such a generator isn’t easy. You need to focus on different aspects of the generator before buying.

In case if you are new to buying a generator for an enclosed trailer, we can help you with several factors. Check these factors before you decide to buy.


Capacity Of The Generator

This is the first thing you should watch on a generator. The capacity of the generator you will buy should be determined by the total required wattage of devices or appliances you want to power up with the generator.

If you have a lot of appliances in your enclosed trailer, you are going to need a generator between 3000-4000W. As we have already mentioned, keep some extra power in your sleeves if an emergency arises.

Fuel Type

Depending on the fuel type, generators for enclosed trailers are of two types. Solar-powered generators are used for light purposes such as lighting up the inside of enclosed trailers or charging mobile devices.

These generators are very lightweight and affordable. But if you have heavy appliances to run, solar generators won’t be enough. Go for a propane or diesel generator that will produce enough power for all your needs.

You can also choose a dual fuel generator where you can switch between two types of fuels.

Noise Level

What if you are enjoying the serenity of nature while camping in solitude and need some power to fire up the induction cooker? The loud noise of some generators can break the peace apart.

Always check the rated noise level to ensure you don’t need to scream while the generator is on. Taking a generator with a noise level under 60dB will be fine. Though you might need to spend some extra for quieter generators, the investment will be worth it.


Efficiency refers to the ratio of output and input power. If the efficiency of your generator isn’t standard, you will need to spend a lot on fuels. An efficient generator ensures you get the maximum benefit out of it with the minimum fuel cost.

Duty Cycle

The duty cycle is the ratio of how long the generator can run at a stretch and how long it needs to rest before running again. You might not want your power to be disrupted at midnight.

So, choose a generator that provides continuous power for all your needs. A generator with a higher duty cycle will ensure you never fall short of power when needed.


Generators used in enclosed trailers should be compact and portable to take up as little space as possible. These generators should also be lightweight so that you can carry them to your campsite or anywhere necessary.

Though diesel or gasoline generators are heavier than solar generators, these generators are usually fitted with wheels. So, you can move them around easily without putting much stress on yourself.

Frequently Asked Questions (FAQ)

We would love to answer some of the frequently asked questions about generators for enclosed trailers. Please take a look.

Can I run a generator in the enclosed trailer?

Though manufacturers of enclosed trailers suggest not to use portable generators inside the trailer, you can use a generator in an enclosed trailer by all means. But you need to ensure the exhaust of the generator has a way to go out. Otherwise, the inside of the trailer will be full of Carbon Monoxide.

Should I get a diesel or propane generator for an enclosed trailer?

Diesel generators can be more cost-effective than propane generators when run in open space. But for enclosed trailers, propane generators will be best as they produce less fume and noise. Propane generators are also much compact and lightweight than their diesel counterparts.

Can I use regular gas in my generator?

Yes, you can use regular gas in your generator if it is a gas-powered one. If it is a gasoline generator, you can use regular gasoline with a minimum rating of 87 octane. Also, the fuel needs to be clean and unleaded.

Can you run a generator all night?

Yes, you can keep your generator running all night. But you need to ensure the generator has enough fuel in the tank to run for all those hours. And never go beyond the suggested duty cycle of the generator. However, we recommend you to not operate a generator overnight. It will produce harmful carbon monoxide gas. Plus, it requires a lot of bucks to run a generator all night.

Can I refuel the generator when running?

No, for your life’s sake. Never refuel a generator when it is running. Even you shouldn’t refuel the generator when it is switched off but still hot. Gasoline can ignite with the heat coming from the generator. Let the generator cool down completely, and then refuel it.


Be it your motorhome or campsite; you can almost never live without power. Generators are the only means of getting power on the go. But when the working area is an enclosed trailer, not just any generator will do the job.

Check out your necessary power rating, efficiency, noise level, and other features to ensure you get the best generator for enclosed trailer. A bit of hard work before buying will leave you with a consistent power flow to save you from dark nights to freezing cold.
