The Size Generator For Camper (You Need…)

Campers have become more popular over the last few years but finding a reliable power source was always challenging. Thankfully with advancements in portable power sources, there are now many types of generators in varied sizes available for campers.

An average camper needs a generator that delivers a min of 5500-watts, but a 7500-watt generator would be better. The right size generator for a camper is crucial because all the appliances and utilities in the camper will be running on the power from the generator.

In this post, we will discuss these key points:

• What size generator is best for a camper?
• Suggestions to reduce the size of the generator in a camper
• The difference between a mobile generator and an off-grid generator
• Different generator sizes available for a camper
• Most common questions asked about generator sizes for campers.

Gauging the power needs of a camper can get intimidating but read on for better clarity.

What Size Generator Should Be Used For A Camper?

The power needs of an average camper are between 5500-watts and 7500-watts. All the power needs of the camper will be running on the generator; this includes lights, charging ports, water, heating, and air conditioning systems.

Appliances That Will Run On The Generator Power

All the appliances and utilities will run on the generator; here are some examples:

• The lights of the camper inside and outside
• The water pump system
• The air conditioning system
• The heating system
• The charging ports
• Bigger appliances like stove tops, tv’s, refrigerators, dishwashers, washing machines, and dryers
• Smaller appliances like coffee makers, toasters, hairdryers, blenders, microwaves, and fryers

Power Needs Of The Appliances That Will Run On The Generator

The power needs of the different appliances directly influence the size of the generator you will need to power your camper adequately. Here is a table to illustrate the power needs in the camper:

To calculate the needs you add the current of the applicable utility or appliance together to get total wattage.

Based on calculations using the tables above, a suitable size generator for a camper is between 5500-watts and 7500-watts, depending on what appliances and utilities need to be powered.

It is very important to consider all the utilities, big and small appliances when calculating the number of watts you require to power your camper adequately. Error in calculations may lead to damages to appliances and even the generator.

Options To Reduce The Size Generator Need For A Camper

While it would be great to run the entire camper on the generator’s power, there are ways to reduce the size of the generator needed for a camper.

• You can run some of the bigger appliances on gas to reduce the size of the generator, such as the stove, the refrigerator, the heating system.
• You can run some of the smaller items on a small solar system, such as the lights, the charging ports, and tv.
• You can pump water once a day into suitable containers, thus leaving extra power in the evenings for heating, it helps to distribute the load.
• Depending on where you choose to camp, you might not need to use the water heating system or the water pump in your camper as some campsites have bathroom and laundry facilities.

Are Off-Grid And Mobile Generators Different In Size?

There are a few differences between off-grid and mobile generators and their sizes. Off-grid generators are bigger and used more permanently, while mobile generators are smaller and mainly used temporarily, like on vacation in a camper.

Below we will go into more detail concerning off-grid generators and the smaller mobile or portable generators that are used as power sources for campers.

Off-Grid Generators

Off-grid generators can be installed in a camper for a more permanent power source. Off-grid generators are bigger and have more power output than mobile generators. Off-grid generators are best suited for people who live in their camper more permanently.

Off-grid generators are an excellent option if you have to power more than one camper. There are entire communities of campers that power their campers by sharing the power generated from one big off-grid generator.

Mobile Generators

Mobile or portable generators are smaller and lighter than off-grid generators and easy to hook up to a camper or remove. They have less power output than the bigger off-grid generators and are best suited for vacations or short road trips.

Even though mobile generators are smaller than off-grid generators, some models can easily power an entire camper, including utilities and appliances.

FAQ About Generator Sizes For Campers

Some frequently asked questions and their answers regarding generator sizes for campers will be:

What Affects The Choice In Size Of A Generator For A Camper?

Many factors play a role in choosing the right size generator for a camper, including:

• The budget you have to work with
• The number of appliances that will run on the generator and their power needs
• The quality of the generator (cheap is not always the best option)
• The warranty the manufacturers give

What Happens If A Wrong Size Generator Is Used For A Camper?

A few things can happen when the wrong size generator is used for a camper.

Using a generator that is too small for the camper needs (overloading):

1. There will be unreliable power, and the generator will throttle the appliances as it tries to stabilize the current.
2. The generator can overheat as the power needed outweighs the current it can provide. It could cause power surges that, in turn, can damage or completely fry the appliances and devices attached to the generator.
3. When a generator is trying to give out more current than it can handle, it will drop its voltage but still try hard to up the current; it will overload and can cause damage to the generator itself.
4. Overuse of the wrong size generator will mean it burns out faster, and you will need to replace it sooner; a generator is a big investment, and choosing the wrong size will be costly in the end.

Using a generator that is too big for the camper needs (Underloading):

1. If you use a generator that is bigger than the total load of your camper, it creates low cylinder pressure, making the Genset work harder to maintain its efficiency. It will cause a build-up of soot that will clog the cylinders breaking the generator.
2. It will be very costly to run; you can save a lot of money by properly calculating the generator’s size and avoiding underloading your generator.

What Warranty Does The Right Size Generator For Camper Have?

A warranty on a suitable size generator for a camper shows that the manufacturer believes in their product. A good warranty for a generator is between 2-5 years.

Some manufacturers have terms attached to their warranties called limited warranties. It means that if the manufacturer finds there is a fault on the generator due to misuse or negligence, the warranty will be void, and all repair costs will fall to the owner.

It is why buying the correct size generator from the beginning is crucial, and ensuring you read the warranty terms and conditions carefully will protect you from costly mistakes.

How Does The Size Of Camper Generator Affect The Placement?

The correct placement of a camper generator is not really affected by its size; however, if the generator you choose does not fit in the allocated space and has to be set up outside without any protection, it could damage the inner components and the outer protective shell.

Remember that the bigger the generator is, the more current it needs to produce. It, in turn, leads to more toxic fumes escaping from the exhaust. A build-up of these gasses can be a health hazard. So proper placement of any size generator is key.

Experts suggest placing bigger generators at least 10 feet from the camper or investing in a proper gas extraction system.
