Buying Guide: Portable RV Generators
What power range do you need? For most RV needs, a generator in the 3000–5000 running watts range covers air conditioning, lighting, and appliances. If you run high-draw equipment or plan to charge EVs, consider 6000+ surge watts and dual-fuel options.
Is inverter technology important? Yes. Inverter generators provide cleaner power with lower total harmonic distortion, making them safer for sensitive electronics such as laptops and smartphones, and typically run more quietly.
How important is runtime vs. fuel capacity? Larger fuel tanks extend runtime but add weight and size. Gas tanks around 1.0–4.0 gallons are common; consider models with fuel gauges for easier planning on trips.
What about RV compatibility? Look for a dedicated RV outlet (30A or 30R) and a stable 120V service. Some models offer 240V options or dual-fuel capability for versatility in different locations.
Portability and noise matter. If you often camp at quiet sites, prioritize low decibel ratings and light, compact designs. Noise ratings and ECO modes often reflect how considerate the generator will be around neighbors.
Safety and maintenance. Features like CO detectors, low-oil shutdown, and included tool kits help reduce risk. Routine maintenance and oil changes are essential for reliability on long trips.
