Campsite Power: Generators 101

Campsite Power: Generators 101 – Your Essential Guide

Camping offers a fantastic escape into nature, a chance to unplug and recharge – both mentally and spiritually. But sometimes, the call of nature is accompanied by the need for a little modern convenience. Whether it’s keeping medical equipment running, charging essential devices, powering lights after dark, or even enjoying a morning coffee brewed with an electric maker, a reliable source of electricity can significantly enhance your camping experience. For many campers, especially those venturing beyond established campgrounds with hookups, a portable generator is the key to unlocking this convenient power.

But generators aren’t just a simple plug-and-play device. They involve fuel, noise, exhaust, and crucial safety considerations. This "Generators 101" guide will walk you through the basics of using a generator for campsite power, helping you understand what they are, how they work, and how to use them safely and courteously.

Why Consider a Generator for Camping?

While embracing the minimalist camping spirit is great, a generator provides power for:

• Essential Devices: Charging phones, laptops, cameras.
• Comfort: Electric fans in hot weather, small electric heaters in cold, electric blankets.
• Lighting: Running camp lights or string lights beyond battery life.
• Cooking & Kitchen: Electric kettles, coffee makers, blenders, small microwaves (requires a larger generator).
• Medical Needs: Running CPAP machines, nebulizers, or charging medical devices.
• Entertainment: Running a projector for outdoor movies, charging portable speakers.
• RV Appliances: Depending on size, powering some RV outlets, lights, or even air conditioning (again, requires significant power).

Understanding the Two Main Types: Conventional vs. Inverter

Not all portable generators are created equal, especially when it comes to campsite use. The primary distinction you need to understand is between conventional generators and inverter generators.

1. Conventional Generators:

   • How they work: A standard engine drives an alternator directly, producing AC power at a fixed frequency (usually 60 Hz in North America).
   • Pros: Generally less expensive to buy upfront, available in larger sizes.
   • Cons: LOUD! This is the biggest drawback for camping. The engine runs at a constant speed regardless of the power draw, leading to high noise levels. They often produce power that isn’t as "clean," which can potentially harm sensitive electronics like laptops and phones. Heavier and less fuel-efficient than inverters.
   • Best for: Job sites, powering tools, backup power for homes where noise isn’t a primary concern. Not ideal for most camping situations due to noise.

2. Inverter Generators:

   • How they work: The engine produces AC power, but this is then converted to DC power, and then converted back to clean AC power using an inverter. The engine speed can vary based on the power demand, making them much more fuel-efficient and significantly quieter.
   • Pros: Much Quieter! This is their defining feature for camping. They produce clean, stable power suitable for sensitive electronics. More fuel-efficient, lighter, and more compact than conventional generators of similar output. Many can be run in parallel (connected together) to double the power output.
   • Cons: More expensive upfront than conventional generators of comparable output. Smaller maximum power output compared to the largest conventional generators.
   • Best for: Camping, tailgating, RVing, powering sensitive electronics, situations where noise and fuel efficiency are important. Ideal for most camping scenarios.

For campsite power, an inverter generator is almost always the preferred choice due to its significantly lower noise level and cleaner power output.

Sizing Your Generator: How Much Power Do You Need?

Choosing the right size generator (measured in watts) is crucial. Too small, and it won’t power what you need; too large, and you’ve spent extra money for unnecessary weight and fuel consumption.

Here’s how to figure it out:

1. List Your Devices: Make a list of everything you might want to power simultaneously.
2. Find the Wattage: Look for the wattage (W) listed on each device. Appliances often list "running watts" (what they use continuously) and "starting watts" or "surge watts" (a temporary spike needed to start motors, like in refrigerators, air conditioners, or even some coffee makers).
3. Calculate Running Watts: Add up the running watts of all devices you plan to use at the same time.
4. Calculate Starting Watts: Identify the device with the highest starting wattage. You only need to account for the surge of one device at a time, as you typically won’t start two high-draw appliances simultaneously.
5. Total Required Watts: Add the total running watts (Step 3) to the highest starting watts (Step 4). This is the minimum starting wattage your generator needs. The generator’s running wattage should be at least equal to your total running watts (Step 3).

Example:

• CPAP Machine: 50W (running)
• Laptop Charger: 100W (running)
• Camp Lights: 50W (running)

• Small Coffee Maker: 800W (running), 1200W (starting)

• Total Running Watts: 50 + 100 + 50 + 800 = 1000W
• Highest Starting Watts: 1200W (Coffee Maker)
• Required Running Watts: 1000W
• Required Starting Watts: 1000W (total running) + 1200W (highest starting) = 2200W

In this example, you would look for a generator with a running wattage of at least 1000W and a starting/surge wattage of at least 2200W. Many generators are rated by their maximum (starting) and continuous (running) watts. Look for one that meets both criteria. When in doubt, it’s often better to slightly oversize than undersize.

Key Features to Look for in a Camping Generator:

• Noise Level (Decibels – dB): This is paramount. Look for generators rated under 60 dB at 20 feet, with lower numbers being significantly quieter. Inverter generators typically fall in the 50-60 dB range. Conventional generators can be 70 dB or higher – a massive difference!
• Runtime: How long will it run on a tank of fuel at a typical load? Longer runtime means less refueling.
• Weight and Portability: Will you be carrying it short distances? Look for models with handles or wheels if weight is a concern.
• Fuel Type: Most are gasoline. Some run on propane (cleaner burning, easier storage, but slightly less power). Dual-fuel models offer flexibility.
• Outlets: Ensure it has the types and number of outlets you need (standard 120V, maybe a 30A RV outlet, USB ports).
• Parallel Capability: If you anticipate needing more power later, consider two smaller generators that can be linked together.

Crucial Safety Considerations:

Using a generator involves managing combustion and electricity. Safety is paramount.

• Carbon Monoxide (CO) Poisoning: Generators produce CO, an odorless, colorless, deadly gas. NEVER run a generator inside a tent, RV, cabin, or any enclosed or partially enclosed space.

  • Placement: Always operate outdoors, well away from occupied structures (tents, RVs, cabins) and downwind. A distance of 15-20 feet is a common recommendation.
  • CO Detector: Install battery-operated CO alarms in your tent or RV. This is non-negotiable.

• Fire Hazards:

  • Refuel only when the generator is completely cool. Gasoline on a hot engine or exhaust can ignite instantly.
  • Store fuel in approved containers away from the generator and any ignition sources.
  • Place the generator on a level, stable surface in a clear area free of dry leaves, grass, or other flammable materials.

• Electrical Safety:

  • Use appropriate, outdoor-rated extension cords designed for the generator’s output. Damaged cords are a fire and shock risk.
  • Do not overload the generator.
  • Grounding: Follow the manufacturer’s instructions for grounding. Some generators need to be connected to a grounding rod driven into the earth, especially if powering permanent structures or used as backup power, but the requirements can vary for recreational use; always check your manual.

• Handling: Allow the generator to cool down before moving it. Ensure adequate ventilation around the generator during operation.

Campsite Etiquette and Regulations:

Using a generator impacts your neighbors and the environment. Be a responsible camper:

• Noise: This is the biggest complaint. Always use an inverter generator for camping to minimize noise. Position it as far as possible from neighboring campsites and point the exhaust/muffler away from others.
• Quiet Hours: Most campgrounds have strict quiet hours (e.g., 10 pm to 7 am). Generators are typically not allowed to run during quiet hours. Plan your power needs accordingly.
• Regulations: Check campground rules BEFORE you bring a generator. Some campgrounds prohibit them entirely, especially in tent-only areas or designated "quiet zones." Others have specific restrictions on runtime, noise levels, or where they can be placed.
• Exhaust: Ensure the exhaust fumes are directed away from tents, RVs, common areas, and neighboring sites.

Basic Maintenance:

Like any engine, generators need maintenance:

• Check Oil: Check the oil level before each use. Change the oil according to the manufacturer’s schedule.
• Fuel: Use fresh, clean fuel. Stale fuel can cause starting problems and damage the carburetor. Use a fuel stabilizer if storing the generator for more than a month.
• Air Filter: Clean or replace the air filter as needed.
• Storage: Follow storage instructions, which usually involve running the carburetor dry or using stabilizer, and storing in a dry place.
• Run Periodically: Even if you don’t camp often, start and run the generator every few months to keep components lubricated and the engine healthy.

Frequently Asked Questions (FAQs)

Q: Are generators allowed in all campgrounds?
A: No. Many campgrounds, especially state and national parks, have strict regulations or outright bans on generators, particularly in certain loops or during quiet hours. Always check the specific campground’s rules before your trip.

Q: How loud is "too loud" for a campsite generator?
A: While subjective, a generator producing more than 60 decibels (dB) at 20 feet is generally considered disruptive in a quiet campground setting. Many regulations aim for this level or lower. Inverter generators are designed to be below this threshold.

Q: Can I run my generator all night to power a CPAP machine?
A: While technically possible with a large enough tank, it’s usually against campground quiet hours and significantly increases the risk of CO poisoning while you sleep. A better solution for CPAP is a dedicated CPAP battery backup or a very quiet inverter generator placed far away with a CO detector inside your sleeping area. Check campground rules regarding essential medical equipment.

Q: Can I run sensitive electronics like laptops or phones directly from any generator?
A: It’s strongly recommended to only run sensitive electronics from an inverter generator. Their power output is "cleaner" (more stable voltage and frequency) than conventional generators, reducing the risk of damage.

Q: What’s the difference between running watts and starting watts?
A: Running watts is the power an appliance uses continuously. Starting watts (or surge watts) is a temporary spike in power needed to start appliances with electric motors (like fridges, ACs, pumps). Your generator needs enough running watts for everything running simultaneously and enough starting watts to handle the surge of the single largest-surge item you start.

Q: Is gasoline or propane better for a camping generator?
A: Gasoline is more common, easier to find, and provides slightly more power per BTU. Propane burns cleaner (less smell and fumes), stores indefinitely, and is often safer to transport and handle (no spills). Dual-fuel generators offer the best of both worlds.

Q: Do I really need a carbon monoxide detector?
A: YES, absolutely. CO is undetectable by smell or sight and can be fatal in minutes. A battery-powered CO alarm is essential safety equipment whenever you’re using a generator near occupied spaces.

Q: How far away from my tent/RV should I place the generator?
A: A minimum distance of 15-20 feet (about 5-6 meters) and downwind is a common recommendation. The further away, the better for noise and CO safety.
