Buying Guide for the Best Generac RV Generators

Choosing the right Generac RV generator can significantly enhance your travel experience by providing reliable power for your appliances and devices. When selecting a generator, it's important to consider several key specifications to ensure it meets your power needs, operates efficiently, and fits within your RV's space and weight constraints. Understanding these specifications will help you make an informed decision and select the best generator for your RV lifestyle.
Power Output (Wattage)Power output, measured in watts, indicates how much electricity the generator can produce. This is crucial because it determines what appliances and devices you can run simultaneously. Generators typically range from 2,000 to 12,000 watts. For light use, such as charging devices and running small appliances, a generator with 2,000 to 4,000 watts may suffice. For more demanding needs, like running an air conditioner or multiple appliances, you might need 5,000 to 7,000 watts or more. Assess your power needs by listing the wattage requirements of your essential devices and choosing a generator that can handle the total load.
Fuel TypeGenerators can run on various fuel types, including gasoline, propane, and diesel. The fuel type affects the generator's efficiency, cost of operation, and availability of fuel. Gasoline generators are common and easy to refuel but may require more frequent maintenance. Propane generators are cleaner and have a longer shelf life but may be less efficient. Diesel generators are fuel-efficient and durable but can be noisier and more expensive. Consider your travel habits and fuel availability when choosing the fuel type that best suits your needs.
Noise LevelNoise level, measured in decibels (dB), is important for comfort and compliance with campground regulations. Generators can range from 50 dB (quiet) to over 80 dB (loud). A quieter generator (50-60 dB) is ideal for minimizing disturbance, especially in quiet campgrounds or when you need to run the generator at night. If noise is less of a concern, you might opt for a more powerful but louder generator. Consider where and how you plan to use the generator to determine the acceptable noise level for your situation.
Size and WeightThe size and weight of the generator affect its portability and storage. RV generators can vary significantly in these aspects, with smaller models weighing around 50 pounds and larger ones exceeding 200 pounds. A compact and lightweight generator is easier to transport and store but may offer less power. Conversely, a larger generator provides more power but requires more space and effort to move. Evaluate your RV's storage capacity and your ability to handle the generator's weight when making your choice.
Run TimeRun time refers to how long the generator can operate on a full tank of fuel. This is important for planning your power usage and refueling needs. Generators with longer run times (8-12 hours) are ideal for extended use without frequent refueling, which is convenient for overnight use or long days off-grid. Shorter run times (4-6 hours) may be sufficient for occasional use or shorter trips. Consider your typical usage patterns and how often you want to refuel when selecting a generator with an appropriate run time.
Starting MechanismThe starting mechanism determines how you start the generator. Common options include manual recoil start, electric start, and remote start. Manual recoil start is reliable but requires physical effort. Electric start is more convenient, allowing you to start the generator with the push of a button. Remote start offers the highest convenience, enabling you to start the generator from a distance. Choose a starting mechanism based on your preference for ease of use and convenience.
