How to Choose the Best Dual Fuel Inverter Generators for RVs
Power Output Requirements
Calculate your RV’s total wattage needs before buying a generator. Add up the running watts of all appliances you’ll use simultaneously, then add 20% as a safety buffer.
Air conditioners typically need 2000-3500 watts, while refrigerators use 600-800 watts. Smaller RVs can work with 3000-4000 watts, but larger rigs with multiple AC units need 6000+ watts.
Fuel Flexibility and Runtime
Dual fuel capability lets you switch between gasoline and propane based on availability and cost. Propane typically produces slightly less power but burns cleaner and stores longer without degradation.
Check the fuel tank capacity and runtime at various loads. Most generators provide 8-17 hours on a full tank at 25% load, which is ideal for overnight operation.
Noise Level Considerations
Quiet operation matters in campgrounds with noise restrictions. Inverter generators run significantly quieter than traditional models, typically between 52-74 dB at quarter load.
Look for models with ECO mode that automatically reduces engine speed during light loads. This feature cuts both noise and fuel consumption during extended use.
Portability and Storage
Consider weight and mobility features if you’ll move the generator frequently. Models with wheels and telescoping handles make transport easier, especially for heavier units.
Measure your RV’s storage compartments before purchasing. Compact designs fit better in limited spaces, while larger generators may require external mounting or trailer storage.
Safety Features and Warranty
CO sensors are essential for RV use since generators often run near living spaces. Automatic shutdown prevents dangerous carbon monoxide buildup in enclosed areas.
Look for low-oil shutdown, overload protection, and fuel shutoff features. A minimum three-year warranty indicates manufacturer confidence and provides peace of mind for your investment.
Frequently Asked Questions
Can I run my RV air conditioner on a dual fuel inverter generator?
Yes, but you need at least 3000-3500 running watts for a single 13,500 BTU RV air conditioner. Larger units or multiple AC systems require 5000-9000 watts depending on your setup.
Is propane or gasoline better for RV generators?
Both have advantages—gasoline provides slightly more power and is widely available, while propane burns cleaner, stores indefinitely, and is often cheaper at RV parks. Dual fuel gives you the flexibility to use whichever is more convenient.
How loud are dual fuel inverter generators?
Most dual fuel inverter generators operate between 52-74 dB at quarter load, comparable to normal conversation or background music. This makes them suitable for campgrounds with noise restrictions.
Do I need electric start on my RV generator?
Electric start is highly convenient but not essential. It’s particularly valuable in cold weather or for users who struggle with pull cords, though it does add to the initial cost.
How often should I run my dual fuel generator?
Run your generator under load for at least 30 minutes every month to keep internal components lubricated and prevent carburetor issues. This maintenance extends engine life significantly.
Final Thoughts
The WEN DF680iX offers the best overall combination of power, features, and EV charging capability for most RV owners. For budget-conscious buyers, the WEN DF360iX delivers excellent value and portability.
Choose based on your actual power needs, storage space, and budget. Don’t overpay for capacity you won’t use, but ensure you have enough watts for essential appliances plus a safety margin.
Whichever model you choose, dual fuel capability and inverter technology make these generators reliable companions for any RV adventure.
