Why Choosing the Right Generator Size Matters

Picking the right generator size transforms our camping experience. A generator too small fails to run critical devices, like a fridge for food storage. A generator too large is heavy, loud, and burns extra fuel, making it tough to carry and disruptive to nature’s calm.

On a group camping trip, we brought a 1000-watt generator, expecting it to handle a small fridge and phone chargers. It overloaded and shut off mid-trip, forcing us to choose between fresh food and charged phones.

By matching the generator’s wattage to our needs, we save space, reduce noise, and enjoy a smooth trip. We’ll guide you through avoiding these pitfalls with practical steps tailored to your camping needs.

Common Mistakes to Avoid

• Underestimating Wattage: Guessing power needs leads to an underpowered generator. We’ll show you how to calculate accurately.
• Ignoring Noise: Loud generators disturb the campsite. We’ll highlight quiet options for peaceful trips.
• Overlooking Portability: Heavy generators are hard to move. We’ll focus on models that balance power and ease of transport.

How to Assess Your Camping Power Needs

Pin it

To find the right generator, we need to know exactly how much power our devices use. We’ll walk you through a simple process to list your gear, calculate wattage, and plan for simultaneous use, ensuring you pick a generator that meets your needs without guesswork.

Step 1: List Your Essential Devices

Start by writing down every device you’ll use at the campsite. Common camping gear includes:

• LED lights for tents or pathways
• Phone or tablet chargers
• Portable fans for warm nights
• Small refrigerators to keep food and drinks cold
• Laptops or tablets for movies or work
• Electric grills or coffee makers for luxury camping
• Portable heaters for chilly evenings
• CPAP machines for medical needs

On a mountain trip, we brought a small fridge, LED lights, phone chargers, and a fan. Listing everything revealed we needed more power than a basic charger could provide.

Step 2: Calculate Total Wattage

Every device uses power, measured in watts, with two types to consider:

• Running Watts: Power needed to keep the device running continuously.
• Starting Watts: Extra power some devices need to start, like fridges or fans (also called surge watts).

Check the device’s label or manual for wattage. Here’s a comprehensive table of common camping devices to help you plan:

Device	Running Watts	Starting Watts
LED Light	5-10W	0W
Phone Charger	5-20W	0W
Tablet Charger	10-30W	0W
Portable Fan	20-50W	50-100W
Small Fridge	50-150W	100-600W
Laptop	50-100W	0W
Electric Grill	600-1000W	0W
Coffee Maker	600-1200W	0W
Portable Heater	1000-1500W	1500-2000W
Air Conditioner (RV)	1000-3500W	2000-6000W
Microwave	1000-1500W	0W
CPAP Machine	30-60W	100-200W

To calculate total wattage, add the running watts of all devices you’ll use at once. Then, add the highest starting watts from any device. For example:

• LED Light: 10W
• Phone Charger: 20W
• Portable Fan: 50W (100W starting)
• Small Fridge: 100W (400W starting)

Total running watts = 10 + 20 + 50 + 100 = 180W. The highest starting watts is 400W (fridge). Total needed = 180W + 400W = 580W. We’d choose a generator with 700-800W to include a 10-20% buffer for safety, preventing overloads. This buffer saved us from tripped generators on multiple trips.

Step 3: Plan Simultaneous Use

Think about which devices you’ll run together. On a family trip, we ran a fridge and fan constantly but used the coffee maker only in the morning. This let us pick a smaller generator than if everything ran at once. Prioritize high-wattage devices and stagger usage to manage power efficiently. We’ll help you create a usage plan to optimize your generator choice.

Expert Tip

Always verify wattage in device manuals. We once underestimated a fridge at 50W, but it needed 150W running and 600W starting. It tripped our generator, spoiling food. Now, we check numbers and add a buffer to avoid surprises, ensuring reliable power for every trip.
