How to Choose Best Portable 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% buffer for startup surges.
Air conditioners typically need 2000-3000 watts, while microwaves use 1000-1500 watts. Smaller RVs can manage with 3000-4000 watts, but larger rigs with multiple AC units need 7000+ watts.
Fuel Type and Availability
Gasoline generators are most common and fuel is widely available, but gasoline degrades over time in storage. Propane stores indefinitely and burns cleaner, making it ideal for occasional use.
Dual-fuel or tri-fuel models provide flexibility but cost more upfront. Battery power stations eliminate fuel concerns entirely but have limited capacity and require recharging infrastructure.
Noise Level Considerations
Many campgrounds enforce strict noise limits, typically 60-70 dB maximum. Inverter generators run significantly quieter than traditional models, usually under 75 dB at quarter load.
Check the noise rating at 23 feet distance, which represents typical campsite spacing. Quieter operation improves relationships with neighbors and enhances your own camping experience.
Portability and Weight
Generator weight ranges from 50 to over 200 pounds depending on power output. Consider how often you’ll move it and whether you can lift it alone or need help.
Built-in wheels and handles improve portability significantly. Compact designs fit better in RV storage compartments, while open frames provide easier maintenance access.
Runtime and Fuel Efficiency
Longer runtime means fewer refueling interruptions during overnight use. Look for at least 8-10 hours at quarter load for comfortable overnight operation.
ECO mode throttles engine speed based on demand, significantly extending runtime and reducing fuel consumption. Fuel gauges help you monitor levels and avoid unexpected shutdowns.
Frequently Asked Questions
What size generator do I need for a 30-amp RV?
A 30-amp RV typically needs 3000-4000 watts to run basic appliances and one air conditioner. Choose a generator with at least 3600 peak watts for comfortable operation with startup surge capacity.
Can I run my RV air conditioner on a portable generator?
Yes, most portable generators rated 3000 watts or higher can run a single 13,500 BTU RV air conditioner. Larger 15,000 BTU units or multiple ACs require 4000+ watts.
Are inverter generators better for RVs than conventional generators?
Inverter generators are generally better for RVs because they’re quieter, more fuel-efficient, and produce cleaner power safe for electronics. They cost more but provide better camping experience.
How long can a portable generator run continuously?
Most portable generators can run 8-12 hours continuously at quarter load before needing refueling. Always allow cooling periods every 24 hours and perform regular oil checks for extended use.
Do I need a transfer switch for my RV generator?
RVs typically don’t need transfer switches since you plug directly into the generator using the RV power cord. Transfer switches are mainly for permanent home backup installations.
Final Thoughts
The PowerSmart 4400-Watt offers the best value for budget-conscious RVers, while the Westinghouse 12500 handles heavy-duty power needs with tri-fuel flexibility.
Consider your power requirements, fuel preferences, and noise restrictions when choosing. Inverter technology and safety features like CO sensors are worth the investment for regular use.
Match your generator to your actual needs rather than overbuying, and you’ll enjoy reliable power for years of RV adventures.
