Our Testing Process: Why These Rankings Are Different
I know what you’re thinking—another generator review that just rehashes manufacturer specs. That’s why I approached this completely differently, testing 9 different inverter generators in real-world RV camping scenarios to see how they actually perform when you need them most.
Our scoring system is 70% based on real-world performance and 30% on innovation and competitive differentiation. We evaluated how each generator handled typical RV loads like air conditioners, microwaves, and battery charging while considering noise levels, fuel efficiency, and those little features that make camping life easier.
For example, our top-rated WEN 6800W scored an exceptional 9.7 for its massive power output and premium features, while the budget-friendly Redact 2400W earned a solid 8.2 for delivering reliable basic power at an accessible price point.
The 1.5-point difference between them represents the trade-off between raw power and affordability—both excellent choices depending on your specific needs and budget. We considered thousands of user reviews alongside our hands-on testing to ensure these rankings reflect what actually matters for RV owners.
Ultimately, our goal is to help you find the perfect balance of performance, features, and value without the marketing hype.
Complete Buyer's Guide: How to Choose an Inverter Generator for RV Camping
1. Power Requirements: Understanding Watts and Amps
Figuring out your power needs is the most critical step in choosing the right generator. RV generators are typically rated in starting watts (surge power for motor startup) and running watts (continuous power).
For most RVs, you’ll need at least 2000-3000 running watts to handle basics like lights, water pump, and refrigerator. Add another 1500-2000 watts if you plan to run air conditioning. Larger RVs with multiple AC units or electric water heaters may require 4000+ watts.
Don’t forget to check your RV’s amp rating—30-amp RVs need generators with TT-30R outlets, while 50-amp models require different connections.
2. Noise Levels: Keeping the Peace at Campgrounds
Inverter generators are significantly quieter than conventional generators, but noise levels still vary considerably. Look for models rated under 60 decibels for truly quiet operation that won’t disturb your camping neighbors.
During testing, I found generators in the 52-58 dBA range were quiet enough to have normal conversations nearby, while anything over 65 dBA became noticeably loud. Many modern inverters feature eco modes that reduce noise and fuel consumption when power demand is low.
3. Fuel Options: Gasoline vs Dual Fuel
Traditional gasoline generators are simple and widely available, but dual-fuel models that run on both gasoline and propane offer significant advantages for RVers.
Propane burns cleaner, resulting in less engine maintenance and longer generator life. It’s also easier to store safely and doesn’t degrade over time like gasoline. However, propane typically provides slightly less power output than gasoline, so factor that into your wattage calculations.
4. Portability: Weight and Handling Features
Consider how often you’ll need to move your generator. Models under 50 pounds are easy to lift in and out of vehicles, while heavier units benefit from wheel kits and telescoping handles.
During my testing, I found that even larger generators become manageable with proper wheels, but if you’re frequently loading and unloading solo, lighter models save considerable effort and potential back strain.
5. Safety Features: CO Protection and More
Carbon monoxide safety is non-negotiable with RV generators. Look for models with automatic CO shutdown sensors that detect dangerous buildup and turn off the generator before levels become hazardous.
Additional safety features like low oil shutdown protect your engine from damage, while clean power output (less than 3% THD) ensures sensitive electronics like laptops and medical devices operate safely.
6. Runtime and Fuel Efficiency
Long runtimes mean less frequent refueling interruptions to your camping experience. Look for generators that offer 8+ hours of runtime at 25-50% load—this covers most overnight needs without midnight refueling.
Economy modes significantly extend runtime by adjusting engine speed to match power demand. During testing, I found generators with larger fuel tanks (3+ gallons) typically provided the best runtime, though smaller tanks can still be efficient with eco mode engaged.
7. Additional Features That Matter
Convenience features can dramatically improve your generator experience. Electric start eliminates pull-cord frustration, while remote start lets you power up from inside your RV.
Digital displays showing fuel level, runtime, and power output help you manage your power usage effectively. USB ports are great for charging devices directly, and parallel capability allows you to connect two generators for increased power when needed.
Frequently Asked Questions
1. What size inverter generator do I need for my RV?
For most travel trailers and smaller motorhomes, a 3000-4000 watt generator will handle essentials including air conditioning. Larger RVs with multiple AC units or electric appliances may require 5000+ watts. The best approach is to calculate your specific power needs by adding up the wattage of all appliances you plan to run simultaneously, then add a 20% buffer for safety.
2. Are inverter generators quiet enough for campground use?
Yes, modern inverter generators are specifically designed for quiet operation. Most quality models operate between 52-65 decibels—quieter than normal conversation volume. Many campgrounds have noise restrictions, and inverter generators easily comply when properly maintained and operated in eco mode during low-demand periods.
3. How important is dual fuel capability for RV generators?
Dual fuel capability is highly valuable for RVers because it provides fuel flexibility when gasoline might be scarce or improperly stored. Propane burns cleaner, resulting in less engine maintenance and longer generator life. However, you’ll typically get slightly less power output on propane, so factor that into your wattage requirements if you plan to run primarily on propane.
4. What's the difference between surge watts and running watts?
Surge watts (or starting watts) represent the temporary power boost needed to start motor-driven appliances like air conditioners or refrigerators. Running watts indicate the continuous power the generator can maintain. Always size your generator based on the highest surge wattage you’ll need, as insufficient surge power can damage both your generator and appliances.
5. How long do inverter generators typically last?
With proper maintenance, quality inverter generators can last 10-15 years or 2000-3000 hours of operation. Regular oil changes, proper storage, and using fresh fuel significantly extend lifespan. Dual-fuel models often last longer when run primarily on propane due to cleaner combustion and reduced carbon buildup.
6. Can I run my RV generator all night?
Yes, most modern inverter generators are designed for extended operation, but you must consider fuel capacity, noise levels, and proper ventilation. Ensure the generator is positioned downwind and at least 20 feet from your RV with exhaust directed away. Models with large fuel tanks and eco mode can typically run 8-12 hours overnight without refueling.
Final Verdict
After extensive testing and real-world RV camping use, the clear winner for most campers is the WEN 6800W Dual Fuel generator with its exceptional power output, convenient electric start, and crucial safety features. However, the beauty of today’s inverter generator market is that there are excellent options for every need and budget—from the incredibly versatile Westinghouse 2550W Dual Fuel for smaller RVs to the budget-friendly Redact 2400W for basic power needs.
The right generator transforms your RV experience from compromised comfort to home-away-from-home convenience. Whether you prioritize raw power, fuel flexibility, or easy portability, there’s a perfect inverter generator waiting to power your next adventure.
