Calculating Wattage Requirements

Most RV appliances list their wattage on a label or in the owner’s manual. You’ll typically find two types of wattage: running watts and starting watts. Running watts represent the continuous power an appliance needs to operate, while starting watts (also known as surge watts) are the brief, higher burst of power required to start certain motor-driven appliances, like air conditioners or microwaves.

Identify all appliances: Make a list of everything you intend to power with the generator, from the air conditioner and microwave to smaller items like phone chargers and coffee makers.
Note running watts: For each item, find its running wattage.
Note starting watts: For appliances with motors, identify their starting wattage. The highest starting wattage of any single appliance will be a key factor.
Sum running watts: Add up the running watts of all appliances you anticipate using at the same time. This gives you a baseline for the generator’s continuous output.
Consider surge capacity: Your generator’s surge wattage should at least meet the highest starting wattage of any single appliance, in addition to the total running wattage of everything else.

As an example, if your RV’s air conditioner requires 2000 running watts and 3500 starting watts, and you also plan to run a 600-watt microwave and a few 100-watt lights, your generator would need to handle at least 2700 running watts (2000+600+100) and have a surge capacity of at least 3500 watts to accommodate the AC’s startup.

Common RV Appliances and Their Power Consumption

Air Conditioner: Often the biggest power draw, ranging from 1500 to 3500 running watts, with significantly higher starting watts.
Microwave Oven: Typically 600 to 1500 running watts.
Refrigerator (AC mode): 100 to 400 running watts.
Hair Dryer: 1000 to 1800 running watts.
Coffee Maker: 800 to 1500 running watts.
Television: 50 to 200 running watts.
Laptop/Phone Charger: 20 to 100 running watts.

It’s always better to slightly overestimate your needs than to underestimate, providing a buffer for unexpected usage or future additions.

Types of RV Generators

RV generators primarily fall into a few categories: portable, inverter, and built-in (or permanently installed). Each type offers distinct advantages and disadvantages, making them suitable for different RV lifestyles and budgets.

Portable Generators

Portable generators are the most common and often the most affordable option. They are designed to be moved and stored when not in use, offering flexibility.

Pros: Generally less expensive, versatile (can be used for home backup or other applications), easy to replace or upgrade, no permanent installation required.
Cons: Can be heavy and bulky, often louder than inverter generators, require manual setup and fueling, security concerns (theft risk if not secured).
Fuel Types: Most commonly gasoline, but some models can run on propane or dual fuel (gasoline and propane).

These are a good choice for RVers who don’t need continuous power, prefer to keep their options open, or have budget constraints.

Inverter Generators

Inverter generators represent a significant advancement in portable power technology, offering cleaner power and quieter operation.

Pros: Produce clean, stable sine wave power (safe for sensitive electronics), significantly quieter operation, more fuel-efficient, lighter and more compact than traditional portable generators, many are parallel-capable (can link two units for more power).

Key Features and Considerations

Beyond the basic types, several features and specifications differentiate generators. Understanding these will help you fine-tune your choice. Generator for RV

Wattage Output

As discussed, wattage is paramount. Ensure the generator’s running watts meet your continuous needs and its starting watts can handle the surge demands of your most power-hungry appliances. RV generators typically range from 2000 to 7000 watts, with some larger units exceeding this.

Fuel Type

Generators primarily run on gasoline, diesel, or propane. Each has its advantages:

Gasoline: Most common, readily available, but has a shorter shelf life and produces more emissions.
Diesel: More fuel-efficient, longer engine life, often found in larger built-in units for diesel RVs. Diesel fuel is less flammable than gasoline.
Propane: Burns cleaner, longer shelf life, easier storage (no gumming up carbs), but less energy-dense than gasoline, meaning you’ll need more propane for the same power output.
Dual Fuel: Offers the flexibility to switch between gasoline and propane, providing versatility in fuel availability. Generator for RV

Consider what fuel is most accessible and convenient for your travel style.

Noise Level (Decibels)

Noise is a significant factor, especially in campgrounds or quiet natural settings. Generator noise is measured in decibels (dB). For comparison, a normal conversation is around 60 dB. Many campgrounds have noise restrictions, often around 60 dB or less.

Conventional Portable Generators: Can range from 65 dB to 80 dB or more, which can be quite disruptive.
Inverter Generators: Typically operate in the 50 dB to 65 dB range, making them much more agreeable.
Built-in Generators: Vary widely but are generally designed with some sound dampening, often in the 60 dB to 75 dB range.

If peace and quiet are a priority, an inverter generator is usually the best choice. Generator for RV
