Choosing Your RV Generator: A Buying Guide

Power Output and RV Readiness

Your generator must match your RV’s electrical appetite. Start by calculating the total wattage of the appliances you plan to run simultaneously, like the air conditioner, microwave, and lights. Look for a unit with a running wattage that exceeds this total.

Critically, the generator must have the correct outlet. A 30-amp TT-30R receptacle is standard for most RVs. Larger fifth wheels may require a 50-amp 14-50R outlet. Always confirm your RV’s plug type before purchasing. A proper connection is non-negotiable for safe and stable power.

Inverter Technology for Sensitive Electronics

Modern RVs are filled with sensitive electronics, from laptops and TVs to advanced control systems. Inverter generators produce clean, stable power with low total harmonic distortion (THD), typically under 3%. This protects your devices from damaging voltage spikes.

Beyond safety, inverter models are generally more fuel-efficient and significantly quieter than conventional open-frame generators. This makes them ideal for campgrounds with noise restrictions and for preserving your own peace. The difference in sound level and power quality is immediately noticeable.

Fuel Type and Runtime Considerations

Dual-fuel capability offers valuable flexibility. You can use gasoline for maximum power output or switch to propane for cleaner burning, longer engine life, and easier fuel storage. Propane doesn’t degrade like gasoline, making it a reliable long-term option.

Evaluate the generator’s runtime at 25% and 50% load. A longer runtime means fewer refueling interruptions during a movie night or a restful sleep. Models with an eco-mode further extend runtime by automatically adjusting engine speed to the required load. For models built for endurance, see our list of the best Briggs & Stratton generators with long runtime.

Portability, Noise, and Safety Features

Even a powerful generator is useless if you can’t move it. Look for models with sturdy wheels and a balanced handle. Weight is a key factor, especially if you need to load and unload the unit from a storage compartment frequently.

Noise level, measured in decibels (dB), is crucial for campground etiquette. Inverter generators often operate around 60-70 dB, which is comparable to a normal conversation. Essential safety features include carbon monoxide (CO) detection with automatic shutoff, low-oil shutdown, and overload protection to safeguard both you and the generator.

Frequently Asked Questions

What size generator do I need for my 30-amp RV?

A generator with a 30-amp TT-30R outlet and at least 3,500 running watts is a good starting point for most 30-amp RVs. This should handle an air conditioner (around 1,500-2,000 watts) plus several other appliances simultaneously. Always add up the specific starting and running watts of your equipment to be certain.

Can I run my RV air conditioner with a portable inverter generator?

Yes, many modern inverter generators are capable of running an RV air conditioner. You must choose a model whose running wattage exceeds the air conditioner’s requirement, with additional capacity for the initial surge when the compressor kicks on. Always check the air conditioner’s nameplate for its exact wattage demands.

Are dual-fuel generators worth it for RV use?

Dual-fuel generators are highly valuable for RVers. They provide flexibility; you can use readily available gasoline or switch to propane, which burns cleaner and stores indefinitely. This is ideal for seasonal use or emergency preparedness. Propane also creates less carbon buildup in the engine, potentially extending its life.

How important is a carbon monoxide detector on a generator?

It is critically important. Carbon monoxide is a colorless, odorless gas that can be fatal. Never operate a generator inside your RV, garage, or near open windows. A built-in CO detection and shutoff feature, like Briggs & Stratton’s CO Guard, adds a vital layer of safety by automatically turning the unit off if dangerous levels are detected nearby.
