Generator for RV Camper: The Ultimate Buying Guide
Find the perfect portable power source for your RV adventures. From boondocking to emergency backup, we break down everything you need to know about RV generators.
See Top Generator Picks βWhether you're a full-time RVer or a weekend warrior, having a reliable generator for RV camper is essential for modern camping. It powers your air conditioner, refrigerator, lights, and electronics, giving you the freedom to camp anywhereβfrom remote national forests to crowded RV parks.
But with so many options on the market, choosing the right generator can feel overwhelming. This guide simplifies the process. We'll cover everything from power output and fuel types to noise levels and safety, so you can make a confident purchase and enjoy your trips without power worries.
1. Understanding Your RV's Power Needs
Before you start shopping, you need to calculate how much power your RV requires. Generators are rated in watts. You'll see two numbers: Starting Watts (surge power to start motors like an AC compressor) and Running Watts (continuous power to keep things running).
π Common RV Appliances
Air Conditioner (13,500 BTU): 1,500W (start) / 1,000W (run)
Refrigerator: 600W (start) / 150W (run)
Microwave: 1,000W
Converter/Charger: 400W
LED Lights (x10): 100W
β‘ Sizing Guide
Small RV (under 25ft): 2,000W β 3,000W
Medium RV (25-32ft): 3,000W β 4,000W
Large RV (over 32ft): 4,500W+ (or dual generators)
π‘ Pro Tip: Add up the running watts of all appliances you plan to use simultaneously, then add 20% for safety.
For most campers, a 3,000β4,000 watt generator is the sweet spot. It can handle a 13,500 BTU air conditioner, a microwave, and basic electronics without breaking a sweat. If you have a 15,000 BTU AC or a larger rig, you might need 4,500 watts or more.
2. Types of Generators for RV Campers
There are two main types of generators for RV use: conventional (open-frame) and inverter generators. Here's how they compare:
π Inverter Generator
Pros: Ultra-quiet, fuel-efficient, produces clean "sine wave" power safe for sensitive electronics (laptops, phones, CPAP), lightweight, and often parallel-capable.
Cons: More expensive than conventional models.
Best for: Most RVers, especially those who value quiet operation and boondocking.
βοΈ Conventional Generator
Pros: More affordable, higher power output for the price, durable.
Cons: Louder, heavier, less fuel-efficient, produces "dirty" power that can damage sensitive electronics.
Best for: Job sites, emergency home backup, or large RVs where noise isn't a concern.
CampLifeEssentials Recommendation: For RV camping, an inverter generator is almost always the better choice. The quiet operation (50-60 dB) keeps you and your neighbors happy, and the clean power protects your expensive devices. The extra cost is worth it for the peace and quiet.
3. Fuel Types: Gasoline, Propane, or Dual-Fuel?
The fuel you choose affects convenience, runtime, and availability. Here's a breakdown:
- Gasoline: Most common and affordable. Easy to find. However, gasoline degrades over time and can clog carburetors if left sitting for months. Use a fuel stabilizer.
- Propane: Clean-burning, never goes bad, and you can tap into your RV's propane tanks. Runtime is slightly lower than gasoline, and propane is less energy-dense.
- Dual-Fuel (Gasoline + Propane): Gives you flexibility. Use gasoline when propane is low, or use propane for cleaner, long-term storage. Many popular models are now dual-fuel.
- Diesel: Usually found in larger, built-in RV generators (like Onan). Very durable and efficient, but expensive and only practical for diesel RVs.
For most RVers, a dual-fuel inverter generator offers the best of both worlds. You can use propane for quiet, clean, long-term storage, and switch to gasoline for extended runtime.
4. Key Features to Consider
π Noise Level
This is arguably the most important factor for camping. A generator rated at 50-60 dB is considered "quiet" and is suitable for campgrounds with noise restrictions. Over 70 dB is loud and will likely draw complaints.
β‘ Parallel Capability
Many inverter generators can be connected in parallel (using a parallel kit) to double your power output. This is perfect if you buy a smaller 2,200W unit now and want to add a second one later for more power.
πͺ« Electric Start / Remote Start
Pull-starting a generator can be tiring. Electric start (with a key or button) or remote start (from inside your RV) adds incredible convenience, especially in cold weather.
β±οΈ Runtime
Check the runtime at 50% load. A good generator should run for 8-12 hours on a single tank of fuel. Larger fuel tanks and eco-throttle modes (which adjust engine speed to match the load) improve runtime.
π Weight and Portability
Consider how you'll lift and carry the generator. Under 60 lbs is manageable for most people. Over 100 lbs can be difficult to move without help or a wheel kit.
π‘οΈ CO Shutdown / Safety Features
Modern generators often include a carbon monoxide (CO) shutdown sensor that automatically turns off the generator if CO levels become dangerous. This is a crucial safety feature for camping safety.

6. RV Generator Safety Tips
- Never run a generator inside your RV or enclosed space. Carbon monoxide is deadly. Always place the generator outdoors, away from windows and vents.
- Use a heavy-duty extension cord. For outdoor use, use a 10-gauge cord rated for the wattage.
- Keep it dry. Don't operate the generator in rain or snow without a proper generator cover.
- Store fuel safely. Use approved fuel containers and keep them away from the generator when operating.
- Maintain regularly. Change the oil, check the air filter, and run the generator periodically (even when not in use) to keep it in good condition.

7. Frequently Asked Questions
Can I run my RV air conditioner with a 2,000-watt generator?
It depends on the AC unit. A 13,500 BTU AC typically needs 1,500W to start and 1,000W to run. A 2,000W generator might handle it, but you won't have much power left for other appliances. For safety, a 2,200W or 2,500W generator is better.
How long does an RV generator run on a full tank?
Most portable inverter generators run 8-12 hours at 50% load. The larger the fuel tank and the more efficient the engine, the longer the runtime. Models with an "eco-mode" can significantly extend runtime.
Are inverter generators worth the extra cost?
Absolutely. Inverter generators are quieter, produce clean power for sensitive electronics, and are more fuel-efficient. For RV camping, they are the standard choice.
Can I use a generator to charge my RV batteries?
Yes. Your RV has a converter/charger that will charge the house batteries when connected to the generator's 120V outlets. This is a great way to keep your batteries topped up while boondocking.

8. Final Thoughts: Which Generator is Right for You?
Choosing a generator for RV camper doesn't have to be complicated. Start by calculating your power needs, prioritize an inverter generator for quiet operation, and choose a fuel type that fits your camping style.
If you're a weekend camper, a 2,200W β 2,500W inverter generator will likely serve you well. For full-timers or those with larger RVs, a 3,500W β 4,500W dual-fuel inverter generator offers the power and flexibility you need.
Investing in a quality generator will pay off in years of trouble-free camping. Happy trails, and may your power always stay on!
