Our Testing Process: Why These Rankings Are Different
When we set out to find the best generators for travel trailers with AC, we knew we needed to look beyond just wattage numbers and marketing claims. We evaluated 7 different generators specifically for their ability to handle real-world RV power demands.
Our scoring system weights 70% on actual performance – how well they power AC units, their noise levels during operation, and reliability based on extensive user feedback. The remaining 30% focuses on innovation and features that provide genuine advantages, like dual fuel capability, safety sensors, and portability enhancements.
For example, our top-rated WEN 6800W scored an exceptional 9.9 for its massive power output and convenience features, while the budget-friendly Oxseryn 4000W earned a very good 8.8 for delivering solid performance at an accessible price point. The difference reflects the trade-offs between premium power and cost-effectiveness.
We focused on factors that actually matter when you’re camping – like whether you can have a conversation nearby, how easy it is to start on a cold morning, and how long you can run between refuels. Our goal is to give you insights based on what these generators actually deliver in real camping scenarios, not just laboratory specs.
Complete Buyer's Guide: How to Choose a Generator for Your Travel Trailer
1. Understanding Wattage Requirements
Getting the wattage right is crucial for powering your travel trailer’s AC unit. Most RV air conditioners require between 1500 and 3500 running watts, with additional surge watts for startup. Always check your specific AC unit’s requirements and add cushion for other appliances you might run simultaneously.
I learned this the hard way when I underestimated my needs and ended up with a generator that couldn’t handle the AC plus my refrigerator. A good rule of thumb is to choose a generator with at least 20-30% more capacity than your calculated needs.
2. Inverter vs Conventional Generators
Inverter generators are almost always better for RV use because they produce clean, stable power that won’t damage sensitive electronics like your TV, laptop, or the RV’s control systems. They’re also typically much quieter and more fuel-efficient.
Conventional generators might be cheaper, but the dirty power can gradually damage your electronics, and the noise will annoy everyone at the campground. For travel trailer living, the extra cost of an inverter generator is absolutely worth it.
3. Noise Levels Matter More Than You Think
Quiet operation isn’t just a luxury – it’s essential for maintaining good relationships with fellow campers and for your own peace of mind. Look for generators that operate at 60 decibels or less, which is about the volume of a normal conversation.
I’ve been on the receiving end of noisy generator complaints, and it ruins the camping experience. The best RV generators are so quiet you can barely hear them from inside your trailer.
4. Fuel Type and Runtime Considerations
Dual fuel generators offer valuable flexibility – you can use gasoline when it’s readily available or switch to propane for cleaner burning and longer shelf life. Propane also produces fewer emissions, which is better for the environment.
Consider how long you typically camp between refueling opportunities. Generators with larger tanks or better fuel efficiency mean less frequent trips to the gas station, which is especially important in remote areas.
5. Portability and Storage
Weight and size directly impact usability – if you can’t easily load and unload your generator, you’ll dread using it. Look for models with built-in handles and wheels, and consider the storage space in your vehicle or RV basement.
I’ve owned generators that were such a pain to move that I’d sometimes skip bringing them altogether. The best generators balance power with practical portability features.
6. Safety Features You Shouldn't Overlook
Carbon monoxide protection is non-negotiable for RV use. Generators with CO sensors that automatically shut down when dangerous levels are detected can literally save lives. Never operate a generator inside or too close to your living space.
Other important safety features include low-oil shutdown, overload protection, and spark arrestors for use in forested areas. These aren’t just checkboxes – they’re essential for safe operation.
Frequently Asked Questions
1. How many watts do I need to run my travel trailer's air conditioner?
Most travel trailer AC units require between 1500 and 3500 running watts, with startup surge watts that can be 2-3 times higher. A 13,500 BTU unit typically needs about 1500-2000 running watts, while larger 15,000 BTU models might require 2500-3500 watts. Always check your specific AC unit’s specifications and add extra capacity for other appliances you might run simultaneously.
2. What's the advantage of dual fuel generators for RV use?
Dual fuel generators give you flexibility and convenience that single-fuel units can’t match. You can use gasoline when it’s readily available or switch to propane for cleaner operation, longer fuel shelf life, and often quieter running. Propane also produces fewer emissions and is typically safer to store. This flexibility means you’re never stuck without power options, which is crucial when camping in remote areas.
3. How important is noise level when choosing a generator for camping?
Noise level is critically important for both your comfort and campground etiquette. Most campgrounds have noise restrictions, and nothing ruins the peaceful camping experience faster than a loud generator. Inverter generators typically operate between 50-65 decibels, which is about as loud as a normal conversation, while conventional generators can reach 70-80 decibels or more. The quieter operation also means less stress on you and your camping neighbors.
4. Can I run my generator all night to power my RV AC?
Yes, but with important considerations. Modern inverter generators are designed for extended operation, but you need to ensure proper ventilation and follow safe distancing guidelines – never run a generator inside or too close to your RV. Also consider fuel capacity; generators with larger tanks or better fuel efficiency will run longer through the night. Some campgrounds may have specific hours for generator use, so always check local rules.
5. What maintenance do RV generators require?
Regular maintenance is essential for reliable operation. This includes oil changes every 50-100 hours of use, air filter cleaning or replacement, spark plug inspection, and using fuel stabilizer if storing for more than a month. Many modern generators have features like fuel shutoff that help prepare the engine for storage. Keeping up with maintenance not only ensures your generator starts when you need it but also extends its lifespan significantly.
Final Verdict
After extensive testing and evaluation, the WEN 6800W Dual Fuel Generator stands out as our top choice for its massive power output, convenient electric start, and excellent safety features. However, if you’re working with a smaller budget, the Oxseryn 4000W delivers impressive performance at an accessible price point. No matter which generator you choose from our list, you’ll be equipped with reliable power that keeps your travel trailer comfortable and functional wherever your adventures take you. Remember to always prioritize safety, follow manufacturer guidelines, and consider your specific power needs before making your final decision.
