Buyer’s Guide: Choosing the Best Small Portable Generator
Purchasing a portable generator for RVing, camping, or emergency use requires carefully evaluating your needs to pick the right model. Here are the key factors to consider:
Intended Use
First, decide how you plan to use your portable generator. Do you need it for:
- Basic power while camping: For lights, phone charging, fans, etc.
- RV or travel trailer use: To run appliances and AC on the road
- Backup emergency power at home: To keep the fridge, medical devices, etc. running
- Jobsite use: Powering tools and equipment
Your intended application will determine the necessary wattage.
Power Output
Pay attention to the starting and running wattage ratings. The startup watts indicate the maximum it can handle for surge loads. The continuous running watts show its steady power capability once started. Choose a generator with enough output for the items you want to run.
For camping and RV use, a portable generator with 2000-3000 running watts is typically sufficient. For home backup power, choose 3000+ rated watts.
Portability
A key aspect of small generators is easy transport. Check the overall weight, dimensions, and body design. Can you lift and move it comfortably? Does it have a telescopic handle and/or wheels?
Look for compact suitcase-style units under 50 lbs if frequent portability is vital. Our comparison table of the smallest portable models makes it easy to evaluate size and weight.
Noise Level
Quiet operation is important for camping environments. Check the noise rating in decibels (dB). Choose an inverter generator with a rating under 60dB for pleasant, peaceful operation. See our guide on the quietest portable generators for top low-noise picks.
Runtime
How long can you operate on a full tank? The fuel source and capacity determine generator runtime. Smaller gas tanks provide 4-8 hours, while larger integrated tanks offer 8-12+ hours.
If you need extended runtime for RV or home use, choose a model with a larger gasoline fuel tank. Propane offers portability but less run time per tank than gasoline.
Features
Consider extra features that add convenience and versatility:
- Inverter generators – For clean, stable electricity
- Parallel capability – Combine units for more power
- Electric start – Push button starting
- LED indicators – Warnings for overload, low fuel, etc
- Outlets – Variety of 120V household outlets
Budget
Portable generators range from $300 on the low end to $1000+ for premium models. Determine how much you want to spend, and choose the best power output, features, and reliability you can afford. Prioritize key aspects like wattage ratings and noise over extra bells and whistles.
By carefully weighing these factors against your needs and budget, you can find the perfect portable generator! Let me know if you have any other questions.
Frequently Asked Questions
How loud is a “quiet” generator?
Under 60 dB is considered quiet operation, with lower decibels being better for camping and outdoor use. The generators I recommend all operate at noise levels under 60 dB.
What fuel type is best for portable generators?
For a combination of portability and runtime, gasoline tends to be the best option. It provides more energy density than propane in a smaller tank, though propane is more lightweight.
How much power output do I need?
Calculate the starting and running wattage requirements of all devices you want to power simultaneously. For camping basics like lights, phone charging, and small appliances, 1600-2000 watts should suffice. Budget at least 3000 watts for RV or backup power uses.
What affects generator runtime?
The size of the fuel tank and the engine efficiency determine how many hours a portable generator can operate before refueling. At 50% load, expect 6-12 hours on a full tank depending on the model.
What key features should I look for?
Inverter generators provide stable, clean electricity for sensitive devices. Parallel capability lets you link two units for more power. Look for bonus features like electric start, auto shut-off, and built-in batteries.
Conclusion
When you need portable power for outdoor activities like camping, tailgating, or emergency preparedness, a compact, quiet generator allows you to take the comforts of electricity on the go.
Keep an eye out for lightweight, ample power output, lengthy run times, and features like inverters when shopping for the best small portable generators.
