Buying Guide – How to Choose the Best Cheap Gas Generator
Choosing the right generator depends on your specific power needs and usage scenarios. We review the key factors to help you compare options.
Power Output
Power output determines what appliances you can run during an outage. Look for both peak and running watts to ensure it matches your load needs.
Higher running watts allow more devices to run simultaneously for extended periods.
Fuel Type
Generators may run on gasoline, propane, or natural gas. Dual fuel options offer flexibility so you can switch if one fuel runs low.
Propane stores longer than gasoline so it is better for long term emergency prep.
Runtime
Runtime is the duration a generator can run on a single tank of fuel. Longer runtime reduces the frequency of refueling during emergencies.
Check runtime at 25% load to understand how long it lasts for light tasks.
Portability
Portability depends on the weight and design of the unit. Lighter units with handles are easy to carry but heavier ones may need wheels.
If you move the unit often consider models with built-in wheel kits.
Noise Level
Noise levels are measured in decibels and affect comfort in residential areas. Inverter generators are usually quieter than conventional open frame models.
Look for noise ratings under 60 dBA if you need quiet operation.
Safety Features
Safety features like low oil shutdown and CO protection are crucial for user safety. CO alert technology stops the engine if dangerous fumes are detected.
Always check for automatic shut off features to prevent engine damage.
Outlets
The number and type of outlets determine what you can plug in. RV ready outlets and USB ports add versatility for camping and travel.
Ensure there are enough 120V outlets for your essential household devices.
Warranty
Warranty terms protect your investment in case of defects or failures. Longer coverage periods usually indicate better manufacturer confidence in quality.
Check for labor and parts coverage when comparing different models.
How to Use and Care for Your Cheap Gas Generator
Always operate the generator outdoors in a well ventilated area. Never run it indoors or in garages to avoid carbon monoxide poisoning risks.
Regular maintenance includes changing oil and checking fuel levels. Follow the manual for recommended service intervals to keep the engine running smoothly.
Store the generator in a dry place and use a fuel stabilizer for long term storage. This prevents fuel degradation which can damage the carburetor over time.
Frequently Asked Questions
What should I run first during a power outage?
Prioritize essential appliances like refrigerators, medical devices, and lighting. Avoid running high wattage items like heaters or air conditioners unless you have a high capacity unit.
Is it safe to run a generator at night?
Yes but place it far from windows and sleeping areas. Ensure ventilation is adequate and consider a quieter inverter model to avoid disturbing sleep.
How often should I change the oil?
Check the manual but typically after the first 20 hours of use and then every 100 hours. Regular changes extend the life of the engine significantly.
Can I connect a generator to my home electrical panel?
Yes if you use a transfer switch installed by a qualified electrician. Direct connection without a transfer switch can backfeed power and endanger utility workers.
What is the difference between peak and running watts?
Peak watts are the maximum power a generator can produce briefly during startup. Running watts are the continuous power it can sustain over time.
How do I know if a generator is RV ready?
Look for a 30A or 50A twist lock outlet on the panel. This specific outlet type matches the standard power cord found on most recreational vehicles.
Why is my generator producing clean power?
Clean power means low Total Harmonic Distortion which protects sensitive electronics. Inverter generators regulate voltage and frequency to ensure safe power for computers and phones.
How do I store gasoline for a generator?
Use an approved fuel container in a cool place. Add a stabilizer if storing for more than three months to prevent gumming in the engine.
