1. How Big of a Generator Do I Need for My Camper?

A 2000-watt generator is often considered a good mid-range option for powering an average-sized camper. It’s capable of supporting essential appliances like lights, cell phone chargers, TVs, stoves, and laptops. However, smaller generators ranging from 500 to 1000 watts can suffice if you only need to power basic necessities, while larger generators exceeding 3000 watts can handle a broader range of appliances.

1.1. Calculating the Right Generator Size for Your Camper

To accurately determine the appropriate generator size for your camper, you must assess the number of appliances you intend to run simultaneously and the duration for which you’ll need power. It’s also crucial to understand the difference between running wattage and surge wattage. Running wattage refers to the continuous power required to keep an appliance operating, while surge wattage is the temporary burst of power needed when starting the appliance.

• Total Running Wattage: Sum of the running wattages of all appliances you plan to use concurrently.
• Total Required Wattage: Total Running Wattage + Highest Surge Wattage.

Calculating Power Needs

2. Understanding Camper Generators

A camper generator serves as a mobile power source, providing electricity to operate appliances and equipment within your camper van. It’s essential to understand how these generators function to determine the appropriate size for your needs. Camper generators typically operate on AC power, allowing you to use the same appliances you would at home.

2.1. Built-in Camper Generators

Built-in camper generators are permanently installed within a designated compartment in your camper. They are hardwired into the camper’s electrical system and draw fuel directly from the vehicle’s fuel tank.

• Pros: High capacity (up to 3000 watts), easy operation via a push-button start inside the vehicle, and automatic performance adjustment at high altitudes.
• Cons: Challenging and expensive maintenance and repairs, potential for carbon monoxide alarm activation even when exhausted outside.

2.2. Portable Camper Generators

Portable generators are independent units that can be connected to your camper’s appliances as needed. They are not integrated into the camper’s wiring or hardware, offering greater versatility and easier maintenance. Portable generators can be powered by various sources, including solar energy, gas, propane, and inverter technology.

3. Understanding Camper Wattage Requirements

The amount of power a camper requires can vary significantly, typically ranging from 2,000 to 12,000 watts. This range depends on the size of the camper and the number and type of appliances you plan to use. Smaller trailers, campers, SUVs, pickup trucks, and minivans may only need around 2000 watts, while larger motorhomes and RVs demand significantly more power.

• 2000-watt generator: Suitable for small RVs with limited electricity needs.
• 4000-watt generator: Ideal for most light-duty RVs and small travel trailers with basic appliances.
• 6000-watt generator: Suitable for larger RVs with heavy-duty appliances such as air conditioners and dishwashers.

The right generator size depends on the camper size, the wattage requirements of your appliances, and their running and starting watts. It’s also crucial to know whether your camper is 30 or 50 amperes to avoid overloading the system.

4. Potential Problems with an Undersized Camper Generator

Using an undersized generator can lead to numerous issues. It may struggle to provide sufficient power to run appliances smoothly, resulting in frequent shutdowns and overloaded breakers. Furthermore, it poses a safety hazard due to potential overheating, which can damage the generator and even the surrounding property.

5. Factors Affecting Camper Generator Performance

Environmental conditions can significantly impact the performance of your camper generator. High humidity, extreme temperatures, and altitude can all reduce the generator’s efficiency.

5.1. High Humidity

High humidity can cause condensation within the generator engine, leading to corrosion and reduced performance. The engine will have to work harder to produce the required amount of power.

5.2. Extreme Temperatures

Extreme temperatures, both hot and cold, can negatively affect generator performance. High temperatures can decrease engine efficiency, increasing fuel consumption. Very low temperatures can damage engine components.

5.3. Altitude

At higher altitudes, there is less oxygen available, which reduces combustion efficiency and increases fuel consumption. Research indicates that power loss can be as high as 16% at 5,000 feet above sea level.

6. Choosing the Right Generator Size for Your Camper (30-Amp and 50-Amp)

A 3,500-watt generator is a versatile option for most camper sizes, particularly 30-amp RVs. However, larger campers may require a 6,000 to 8,000-watt generator. The ideal generator size depends on your intended usage. If you plan to support cooking, heating, and air conditioning for extended periods, you’ll need at least 4000 watts. For lighter use, a 2,000-watt generator may suffice.

6.1. Understanding Basic Electrical Terms

To accurately determine your generator needs, it’s essential to understand the following electrical terms:

• Watts: A measure of power or the rate of energy (Power = Voltage x Current).
• Volts: The unit of voltage, indicating the force applied to an electron.
• Amperes: A measure of current, indicating the flow of electricity.

6.2. Generator Size for a 30-Amp Camper

A 30-amp RV typically has one 30-amp service leg, providing 120 volts to power appliances and outlets. To calculate the required wattage:

Wattage = Volts x Amperes

Wattage = 120 V x 30 Amp

Wattage = 3,600 watts

Therefore, a 30-amp camper can use a shore power of 3,600 watts. While a 4,000-watt generator provides some headroom, a 2,000 to 2,500-watt generator is generally a good fit for 30-amp campers.

6.3. Generator Size for a 50-Amp Camper

Larger RVs often have two legs of 50-amp service. To calculate the maximum power handling:

Wattage = Volts x Amperes

Wattage = 120 V x 50 Amp

Wattage = 6000 watts

Maximum power handling = 2 x 6,000 watts = 12,000 watts

Therefore, a 50-amp RV can utilize a generator with a maximum output of 12,000 watts.

6.4. Generator Size for a 50-Amp RV with 2 AC Units

A 50-amp RV with two AC units typically needs a generator with a power output of 4,000–8,000 watts. However, this can vary based on the wattage of the RV AC units and how long you intend to run them. For example, if each AC unit consumes around 600-1700 watts, you’ll need a generator that can supply more than that. Using a Jackery Solar Generator 2000 Plus Kit (4kWh) with a battery capacity of 4085.6Wh can run RV ACs for 1.0 – 2.8 hours, according to Jackery’s official website.

7. What Size Generator Do I Need for a 25-Foot Travel Trailer?

A 4000-watt generator is typically perfect for most light-duty RVs and small travel trailers with essential appliances. While this size generator can run many travel trailer appliances, you might not be able to use all the appliances simultaneously.

7.1. Calculating Generator Needs for a 25-Foot Travel Trailer

To determine the appropriate generator size for a 25-foot travel trailer, consider the following:

A 25-amp travel trailer will run on 120V and 25A.

Wattage = Voltage × Current = 120V × 25A = 3000W.

Therefore, a 3000-watt generator is ideal for a 25-foot travel trailer. For extra power, consider a 3500-watt generator for RV use.
