How to Choose and Buy the Right RV Generator
Purchasing an RV generator is one of the most important investments you will make for your camping lifestyle. Unlike most gear purchases, getting it wrong can mean either being stranded without power or hauling a heavy, expensive machine that far exceeds your needs. The good news is that with a clear framework for decision-making, you can find the right generator quickly and confidently. Here is everything you need to know before clicking “buy.”
Step 1: Calculate Your Actual Power Needs
The single most important step before buying any generator is knowing how many watts you actually need. Start by listing every appliance or device you intend to run simultaneously during a camping trip. Common RV power consumers include the rooftop air conditioner (1500–2000 watts), a microwave (900–1200 watts), a coffee maker (800–1000 watts), a refrigerator (150–400 watts), a television (100–200 watts), and phone or laptop chargers (20–100 watts each).
Add up the running wattage of everything you plan to operate at the same time. Then identify which of those appliances have electric motors — motors require a surge of extra power at startup, sometimes two to three times their running wattage. Your air conditioner, for example, might run on 1500 watts but need 3000 watts to start. Choose a generator whose peak (starting) wattage exceeds your highest surge demand, and whose running wattage comfortably covers your total simultaneous load. Adding a 10–20% buffer above your calculated total is always a smart practice.
Step 2: Decide Between Portable and Built-In
Portable generators are the most popular choice for RV owners because they are versatile, affordable, and can be used for purposes beyond the RV — tailgating, job sites, and home backup, for instance. They range from compact 2000-watt units to powerful 13,000-watt machines. The trade-off is that they must be set up outside the RV before use, stored securely to prevent theft, and refueled manually.
Built-in generators, also called onboard or coach generators, are permanently installed inside motorhomes and start at the push of a button, drawing fuel directly from the RV’s fuel tank. They are more convenient and produce less noise intrusion inside the cabin, but they cost significantly more, require professional installation, and are only practical in larger Class A or Class C motorhomes. If you own a travel trailer, fifth wheel, or smaller RV, a high-quality portable generator is almost certainly your best option.
Step 3: Choose the Right Fuel Type for Your Situation
Your choice of fuel type will affect everything from day-to-day convenience to long-term storage and maintenance. Gasoline generators are the most common and easiest to fuel on the road, as gas stations are everywhere. However, gasoline degrades over time, making it less ideal if you store your generator for extended periods between trips. Always use a fuel stabilizer if storing a gasoline generator for more than 30 days.
Propane generators are cleaner burning, store indefinitely without degrading, and are practical if your RV already carries propane tanks for cooking and heating. The downside is slightly lower power output compared to gasoline. Dual-fuel generators offer the best of both worlds and are an excellent choice if you want flexibility depending on what fuel is available at your destination. Diesel generators, while efficient and long-lasting, are typically found in large motorhomes and are less relevant for the average RV camper shopping for a portable unit.
Step 4: Understand Inverter vs. Conventional Generators
If you plan to charge laptops, run a CPAP machine, operate a smart TV, or power any modern electronics, an inverter generator is strongly recommended. Inverter generators produce electricity in a cleaner, more stable form with very low Total Harmonic Distortion (THD) — typically below 3%. This matters because sensitive electronics are vulnerable to power fluctuations, and a generator with dirty power can damage or shorten the life of your devices over time.
Conventional generators produce power adequate for tools, lights, and appliances with simple motors but are not recommended for powering electronics directly. They also tend to run louder and at a fixed engine speed regardless of load, making them less fuel-efficient. Inverter generators adjust engine speed to match demand, which reduces noise, extends runtime, and saves fuel. The premium in price is generally worth it for most RV users who camp with modern devices.
Step 5: Pay Close Attention to Noise Ratings
Noise is one of the most frequently overlooked specs until you arrive at a campground and realize your generator is disturbing everyone within 100 feet. Generator noise is rated in decibels (dB). To put the numbers in context: 50 dB is roughly the level of a quiet library, 60 dB is a normal conversation, 70 dB is the inside of a car on the highway, and 80 dB is a vacuum cleaner. Many campgrounds enforce quiet hours (typically 10 PM to 8 AM) and some have explicit maximum decibel limits.
Inverter generators typically operate between 50 and 65 decibels at a distance of 23 feet — most are acceptable for campground use. Open-frame conventional generators often run at 70–80 dB, which will disturb neighbors and may violate campground rules. If you plan to camp frequently at state parks, national forests, or organized campgrounds, prioritize a generator rated at 60 dB or below. Fully enclosed inverter designs offer the best noise isolation.
Step 6: Consider Weight, Size, and Storage
Before purchasing, measure the storage compartment or cargo area where you plan to keep the generator. Portable generators range from about 40 pounds for compact 2000-watt units to well over 200 pounds for large conventional models. Solo travelers should aim for units under 60 pounds for manageable lifting. Look for integrated carry handles, and if you are considering a larger unit, prioritize models with never-flat wheels and a collapsible handle for easier transport across a campsite.
Also confirm that your RV can safely store the generator. Generators must always be operated outdoors and never inside or in an enclosed storage bay due to carbon monoxide risk. Ensure the external compartment has adequate ventilation and that the generator’s footprint fits your available space before finalizing your decision.
Step 7: Verify Outlet Compatibility with Your RV
Not all generators are ready to plug directly into an RV without additional hardware. Most RVs use a 30-amp TT-30R outlet (for smaller rigs) or a 50-amp CS6364 outlet (for large motorhomes). Before purchasing, check your RV’s shore power inlet and confirm the generator includes a matching outlet. Many modern RV-ready generators include the correct outlet, but some require a separately purchased adapter. Buying an incompatible unit and needing a workaround is a frustrating and easily avoidable mistake.
Step 8: Look for Essential Safety Features
A good RV generator should include several built-in safety features. Low-oil automatic shutdown protects the engine from running dry, which can cause permanent damage. Overload protection shuts the generator off if the electrical load exceeds safe limits, preventing both damage to the generator and potential fire hazards. Carbon monoxide (CO) detection and automatic shutdown is increasingly common and highly recommended — CO is odorless, invisible, and potentially lethal.
All seven generators reviewed in this guide include at least some of these protective features. Prioritize models that include CO shutdown as a non-negotiable safety baseline, particularly if you camp with children or pets, or if you have any tendency to operate the generator in close proximity to your RV.
Step 9: Factor in Warranty and Long-Term Support
A generator is not a disposable purchase. Look for manufacturers that offer at least a one-year warranty, with two years or more preferred. Check whether the company has responsive customer support and accessible replacement parts. Brands with a strong service network — either through their own channels or through authorized repair centers — are significantly easier to own over time. Read recent buyer reviews specifically mentioning warranty claims and customer service experiences, as this is where brand reputation is either confirmed or exposed.
Where to Buy
All seven generators in this guide are available on Amazon, which offers reliable shipping, easy returns, and verified buyer reviews that provide real-world insight beyond manufacturer claims. Buying on Amazon also simplifies the warranty claim process for many brands. If you prefer to see a generator in person before purchasing, large home improvement retailers such as Home Depot and Lowe’s carry selected models. Specialty RV dealers may also stock or order specific units and can provide expert advice tailored to your rig. Whichever channel you choose, always confirm the return policy before purchasing in case the generator does not meet your expectations upon arrival.
