The Spark of Freedom: Why You Need a Generator for Camping
Imagine waking up to the smell of fresh coffee brewing in your RV, knowing your phone is fully charged, and the lights are ready for an evening of board games. Or perhaps it's a scorching day, and your air conditioner is humming, keeping the interior cool. This isn't just about luxury; it's about comfort, safety, and extending your time away from crowded hookup sites.
Camping generators provide that vital bridge between wilderness and modern living. They're portable power plants, delivering the juice you need for everything from small personal devices to power-hungry appliances like microwaves and air conditioning units. For anyone serious about boondocking (camping without hookups), extended trips, or even just having peace of mind for emergency preparedness, a reliable generator is an essential piece of gear.
Before You Buy: Essential Questions for Choosing Your Powerhouse
Selecting the right camping generator isn't a one-size-fits-all decision. It involves carefully considering your specific needs, camping style, and budget. Think of it as tailoring a suit – you want it to fit perfectly.
1. How Much Power Do You Really Need? (Wattage)
This is perhaps the most critical factor. Generators are rated by their wattage output.
You'll need to calculate the total simultaneous wattage of all the appliances you plan to run. Don't forget the "starting wattage" or surge wattage for motor-driven items like your RV's air conditioner, refrigerator, or microwave. These appliances temporarily draw significantly more power when they first kick on.
- Small RVs/Basic Camping: 1,000-2,000 watts might cover lights, charging devices, and a small fan.
- Mid-sized RVs/Moderate Use: 2,500-3,500 watts often handle a microwave, lights, and a few small electronics.
- Larger RVs/AC & Appliances: 3,500-4,500+ watts are typically required to run an RV air conditioner, water heater, and other high-draw items.
Pro Tip: Always size up slightly. It's better to have a bit of extra capacity than to constantly overload your generator, which can lead to premature wear and frustrating shutdowns. For a deeper dive into sizing your generator, you might find this guide on how to calculate your RV generator wattage needs incredibly helpful.
2. How Loud is Too Loud? (Noise Levels)
Nothing ruins the tranquility of nature faster than a roaring generator. Noise levels are measured in decibels (dB), and a lower number means a quieter experience.
- Inverter Generators: These modern marvels typically operate between 50-60 dB, akin to a quiet conversation or the hum of a refrigerator. This is generally acceptable in most campgrounds and won't disturb your neighbors or your peace.
- Conventional Generators: Often louder, reaching 70 dB or higher, comparable to a vacuum cleaner or a busy street. Many campgrounds enforce strict quiet hours (e.g., 8 PM to 8 AM), making a noisy generator a non-starter for overnight power.
Considering the growing demand for peaceful campsites, opting for a quieter unit is often a smart investment. To explore options designed for stealth, check out our guide on the quietest camping generators.
3. What Fuel Do You Have Access To? (Efficiency & Availability)
Your generator's fuel source impacts cost, availability, and environmental footprint.
- Gasoline: The most common and widely available fuel. Portable gasoline generators are often affordable and deliver good power. The downsides include lower fuel efficiency compared to diesel, a distinct exhaust odor, and the need to carry extra fuel cans.
- Propane (LP): A cleaner-burning alternative that often connects directly to your RV's existing propane tanks. Pros include reduced emissions, quieter operation, and easier fuel storage (no smelly gasoline cans). Cons: propane is less energy-dense than gasoline, meaning it burns faster and may offer slightly less power output.
- Diesel: The most fuel-efficient option, ideal for long runs and found in larger, often more expensive units. Diesel is the go-to for big Class A diesel pusher motorhomes, as they share the same fuel source.
- Solar: Not a traditional fuel in the combustion sense, but free "fuel" from the sun. Requires an initial investment in panels and batteries, and performance depends on sunlight. Silent and emission-free, it's increasingly popular for those seeking green power.
4. Portable or Built-in? (Flexibility vs. Integration)
This boils down to how you plan to use your generator.
- Portable Generators: Offer immense flexibility. You can move them around your campsite, use them for home backup during power outages, or lend them to a friend. They are generally more affordable but require setup, storage, and are more susceptible to theft if not secured.
- Built-in (Onboard) Generators: Permanently installed within your RV. They offer ultimate convenience with push-button start from inside the coach, excellent soundproofing, and reduced theft risk. The trade-offs are higher upfront cost, fixed location, and they typically draw fuel directly from your RV's main tank.
Diving Deep: The Main Types of Camping Generators Explained
Now let's break down the specific categories so you can understand what each type offers.
1. Portable Generators: Power You Can Take Anywhere
These are the most common generators seen at campgrounds and are known for their versatility.
Gasoline Generators (Conventional)
These are the workhorses of portable power. They're typically more affordable upfront and widely available.
- Pros: Easy to find fuel, good power output for the cost, robust for tools and basic power needs.
- Cons: Can be quite loud (70 dB+), produce strong exhaust fumes, heavier to move, and require carrying separate gasoline containers, which can be a fire hazard if not stored properly. They often produce "dirty" power, which can be risky for sensitive electronics.
Propane (LP) Generators
A popular choice for RVers, especially those who prefer a cleaner burn and have existing propane infrastructure.
- Pros: Cleaner burning (less carbon monoxide), often quieter than gasoline counterparts, can connect to your RV's existing propane tanks for easier fuel management, and propane stores indefinitely without going stale.
- Cons: Less energy-dense than gasoline, so they consume fuel faster for the same power output. Propane can be harder to find in some very remote areas, and they may have slightly less peak power.
Dual-Fuel Generators
The best of both worlds, offering flexibility to switch between gasoline and propane.
- Pros: Maximum flexibility – choose fuel based on availability or preference. If one fuel runs out, you have a backup. Propane is great for cleaner, quieter operation, while gasoline offers maximum power and efficiency when needed.
- Cons: Generally more expensive than single-fuel models due to their more complex design.
Inverter Generators: The Modern Marvel
If you're looking for the gold standard in portable camping power, it's likely an inverter generator. These units convert AC power to DC, then back to "clean" AC power, mimicking grid-quality electricity.
- Pros: Produce extremely stable, "clean" power that is safe for sensitive electronics (laptops, phones, medical devices), significantly quieter operation (50-60 dB), much more fuel-efficient due to their ability to throttle engine speed based on load, lighter and more compact designs, and often feature parallel capability (allowing you to link two smaller units for double the power).
- Cons: Higher upfront cost than conventional generators.
- Why they're superior: For most RVers and campers, the benefits of clean power, quietness, and efficiency far outweigh the extra cost. Many consider them essential for a truly comfortable and quiet camping experience. Dive into the specifics of why inverter generators are worth the investment.
Conventional Generators (Non-Inverter)
These are the traditional type of generator, producing power directly from the engine's RPMs.
- Pros: More affordable upfront, good for raw power to non-sensitive tools (like power drills or circular saws) or resistive loads (like incandescent lights, simple heaters).
- Cons: Typically much louder (70 dB+), less fuel-efficient, and the "dirty" power wave they produce can potentially harm sensitive electronics. They're generally a less suitable choice for modern RVs with sophisticated onboard systems.
2. Built-in (Onboard) Generators: Integrated Power for the Long Haul
Found predominantly in larger motorhomes (Class A, C) and some fifth-wheel trailers, these generators are permanently installed within the RV's chassis. They're often quieter due to dedicated soundproofing and draw fuel directly from the RV's main tank.
Diesel Generators
The powerhouse choice for large diesel pusher motorhomes.
- Pros: Highly fuel-efficient, exceptionally long lifespan, very powerful (often 8,000+ watts), and typically quieter than onboard gasoline units due to robust enclosures and the nature of diesel engines. Diesel fuel is readily available at truck stops.
- Cons: Highest upfront cost, heavier, and require specific diesel engine maintenance.
Gasoline Generators (Onboard)
Common in many Class A and Class C gasoline motorhomes.
- Pros: Convenient fuel source (shares the RV's main gasoline tank, usually has a cutoff when the tank is ¼ full to ensure you don't run out of driving fuel), powerful enough for most RV needs, and integrated for ease of use.
- Cons: Can still be quite noisy despite soundproofing, less fuel-efficient than diesel, and produce exhaust fumes requiring careful ventilation.
LP (Propane) Generators (Onboard)
Less common as a primary onboard power source due to propane's lower energy density, but some smaller units exist.
- Pros: Cleaner burning, quieter than gasoline units, and convenient if the RV already relies heavily on propane for other appliances.
- Cons: Less powerful overall, propane burns faster meaning more frequent refilling of tanks, and may struggle with high-draw appliances like multiple ACs.
3. Solar Generators: The Silent, Green Power Revolution
While technically not "generators" in the fuel-burning sense, solar generator systems fulfill the same purpose: providing off-grid electricity. They consist of solar panels that charge a battery bank, which then powers your RV's 12V system and AC appliances (via an inverter).
- Pros: Silent operation (no noise, no fumes), zero fuel costs once installed, zero emissions, minimal maintenance, and continuous power in sunny conditions. Ideal for charging devices, running lights, and smaller 12V appliances.
- Cons: High initial investment, performance is dependent on sunlight and weather conditions, limited power output compared to fuel generators (especially for high-draw items like AC or microwaves, which require a very robust and expensive system), and requires significant space for panels and batteries.
- Best Use: Excellent for supplementing power, extending battery life, and running small electronics. For serious power needs, often combined with a traditional fuel generator in a hybrid setup. If you're looking to minimize your environmental footprint and enjoy true silence, exploring solar power for your RV is a great next step.
Keeping Your Power Pumping: Maintenance & Safe Operation
A generator is an investment that requires care to ensure it's ready when you need it most.
Pre-Trip Checks & Routine Maintenance
Think of your generator like a small engine in your RV – it needs regular love.
- Pre-Trip: Before heading out, always check oil levels, inspect the air filter for cleanliness, ensure you have adequate fuel, and give it a test run for 15-20 minutes under a light load (e.g., run a fan or charge devices).
- Monthly Run: Run your generator for at least 30 minutes once a month under a moderate load (around 50% capacity). This circulates fluids, lubricates components, and prevents carburetor gumming up from stale fuel.
- Oil Changes: Follow manufacturer recommendations, typically every 50-100 hours of use or annually, whichever comes first.
- Filters: Replace air and fuel filters per the schedule in your owner's manual.
- Spark Plug: Inspect and replace the spark plug periodically.
- Cleanliness: Keep your generator clean, especially cooling fins and air intakes, to prevent overheating.
Proper maintenance can prevent frustrating breakdowns and extend the life of your unit. For a comprehensive list of tasks, read our RV generator maintenance tips.
Safe Operation: Don't Compromise on Safety
Carbon monoxide (CO) is an odorless, colorless, and deadly gas produced by fuel-burning generators.
- Ventilation is Key: ALWAYS operate your generator in a well-ventilated area, at least 20 feet away from your RV's windows, doors, or vents. Never run it inside a tent, RV, garage, or any enclosed space.
- Carbon Monoxide Detector: Ensure you have a working carbon monoxide detector inside your RV, and check its batteries regularly.
- Exhaust Direction: Position the generator so the exhaust is directed away from your living spaces and neighboring campsites.
- Weather Protection: Protect your generator from rain and snow, but ensure adequate airflow. Never cover it completely while running.
- Refueling: Turn off the generator and let it cool before refueling to prevent accidental fires.
Troubleshooting Common Generator Headaches
Even with the best maintenance, generators can sometimes be temperamental. Here are quick fixes for common issues:
- "My generator won't start!"
- Fuel: Check fuel level. For onboard RV generators, the RV's main fuel tank usually needs to be at least ¼ full for diesel or ⅓ full for gasoline for the generator to draw fuel.
- Oil: Low oil levels can trigger an automatic shutoff. Check and top up.
- Choke: For cold starts, ensure the choke is engaged correctly.
- Spark Plug: Inspect, clean, or replace a fouled spark plug.
- Air Filter: A clogged air filter can restrict airflow.
- Battery: For electric start models, check the battery.
- "I'm getting power fluctuations or low output."
- Overload: Are you trying to run too many appliances at once? Reduce the load.
- Stale Fuel: Fuel that's been sitting for months can cause issues. Use fresh fuel, or consider a fuel stabilizer.
- Air Filter: A dirty air filter restricts air, reducing power.
- Altitude: Generators lose power at higher altitudes (typically 3-5% for every 1,000 feet above sea level).
- "My generator keeps overheating or shutting down."
- Ventilation: Ensure it's not enclosed and has plenty of airflow. Clean any cooling fins or air intakes.
- Oil Level: Low oil can cause overheating.
- Load: Reduce the electrical load, especially in hot weather.
