Best Portable Generators for RVs in 2025

Whether you’re boondocking in the desert or plugged into shore power at a campground, reliable electricity is essential for a comfortable RV lifestyle. From keeping the lights on to running your fridge, air conditioner, and microwave, having access to dependable power can make the difference between a smooth journey and a frustrating detour.

Portable generators provide the freedom to camp off-grid, explore remote areas, and maintain modern comforts anywhere your travels take you. They offer RVers a flexible power solution that's both rugged and reliable. Whether you're a weekend warrior or a full-timer a quality fuel-based portable generator can become one of the most important pieces of gear in your setup.

Before diving into the best models of 2025, it’s helpful to understand the types of generators available and what features matter most.

Types of Portable Generators for RVs

Conventional Generators

Traditional or “conventional” portable generators use a mechanical alternator to produce electricity. They tend to be more affordable and can offer higher power output, but they’re generally louder and bulkier than inverter models. These are ideal for powering heavy-duty equipment or multiple appliances at once—though you may need to install additional noise shielding depending on your campground’s rules.

Inverter Generators

Inverter generators are designed to produce clean, stable power that's safe for sensitive electronics like laptops, TVs, and mobile devices. They’re typically more fuel-efficient, significantly quieter, and lighter in weight. This makes them particularly popular with RVers who value quiet operation and portability.

7 Things to Consider When Choosing an RV Generator

Before purchasing a portable generator for your RV, keep these key considerations in mind:

1. Power Output (Wattage Needs)

Think about what you plan to run. A rooftop A/C might need 2,000–3,000 watts to start, while lights and small appliances use much less. Match the generator’s continuous (running) and surge (starting) wattage to your RV’s load requirements.

2. Noise Level

Campgrounds often have noise restrictions, and nobody wants to disturb the peace of nature. Look for inverter models or those rated for quiet operation—typically under 60 decibels (dBA).

3. Fuel Type and Efficiency

Fuel options include gasoline, propane, and natural gas. Dual-fuel and tri-fuel models allow you to switch depending on availability and price. Propane burns cleaner, while gasoline offers convenience.

4. Size and Portability

Consider your RV’s storage capacity and weight limits. Some high-output generators are heavy, while compact inverter models are ideal for travel trailers or solo campers.

5. Runtime

Longer runtimes mean fewer fuel stops. Look at the generator’s fuel tank size and efficiency. Many models advertise runtimes at 25% or 50% load.

6. Parallel Capability

Some inverter generators can be connected in parallel to double their output—great for occasional high-demand use without hauling a heavy-duty unit all the time.

7. Price Point

There’s a wide range of price options depending on power output, features, and fuel flexibility. Stick to what aligns with your actual usage patterns.
