Buying Guide – How to Choose the Best Cheap Gas Generator
Selecting the right generator requires weighing power needs against budget constraints and portability requirements.
Power Output
Determine your total wattage needs by adding up the startup and running watts of appliances you plan to power.
Select a generator with a rated wattage slightly above your total to avoid overload and ensure smooth operation.
Fuel Type and Runtime
Consider if you need dual or tri fuel capability for flexibility in fuel sources during emergencies.
Check runtime at partial load to understand how long the unit can operate between refueling stops.
Noise Levels
Look for decibel ratings below 60 dBA if you plan to use the generator in quiet residential areas or campsites.
Quieter models often cost more but prevent disturbances to neighbors and make conversations easier nearby.
Portability
Evaluate weight and whether the unit includes wheels or handles for easy movement across terrain.
Lighter generators are easier to transport but may offer less power and shorter runtimes compared to heavier models.
Safety Features
Prioritize units with low oil shutdown, circuit breakers, and carbon monoxide detection technology.
These features protect both the generator from damage and your family from hazardous fumes or electrical hazards.
Inverter Technology
Inverter generators provide clean power with low total harmonic distortion safe for sensitive electronics.
They are more fuel efficient and quieter but may come at a higher price than traditional open frame models.
Warranty and Support
Check the length of manufacturer warranty and availability of customer service for parts or troubleshooting.
A longer warranty period offers peace of mind and ensures you can access help if issues arise later.
Price and Value
Compare the upfront cost against features like runtime and portability to find the best value for your use case.
Sometimes spending slightly more on a higher quality unit can save money in the long run through durability.
How to Use and Care for Your Cheap Gas Generator
Always place the generator outdoors in a well ventilated area away from windows and doors to prevent carbon monoxide buildup near living spaces.
Start the engine by connecting it to the fuel source and allowing it to warm up for a few minutes before plugging in any devices.
Perform regular maintenance like changing oil and cleaning air filters after every 50 hours of use to extend the life of the generator.
Frequently Asked Questions
Is a cheap gas generator safe for sensitive electronics?
Only generators with inverter technology provide the clean power needed for sensitive electronics like laptops. Look for low total harmonic distortion ratings below 5 percent to ensure safe operation for your devices.
How much fuel does a typical cheap generator use?
Most models consume about half to one gallon per hour depending on load. Running at half load significantly improves efficiency and extends runtime between refueling stops.
Can I use a generator indoors during a power outage?
Never use a generator indoors or in enclosed spaces due to the risk of carbon monoxide poisoning. Always keep it outdoors and at least twenty feet away from windows.
Do I need to buy oil separately for the generator?
Most generators do not come with pre filled oil so check the package contents carefully. Some include a small bottle but you should verify this before first use to avoid damage.
What is the difference between surge and running watts?
Surge watts indicate the maximum power the generator can handle for short bursts to start motors. Running watts are the continuous power it can deliver for prolonged operation of devices.
How do I store a generator for winter months?
Drain the fuel or add stabilizer to the tank before storage. Run the engine to ensure fuel lines are cleared and store the unit in a dry place to prevent rust.
Are cheap generators loud?
Open frame generators can range from 70 to 80 dBA which is quite loud. Inverter models tend to be quieter at 50 to 60 dBA but cost slightly more for that feature.
Final Thoughts on Choosing the Best Cheap Gas Generator
The Oxseryn and AIVOLT models offer the best balance for budget users needing portability and moderate power for home or camping.
For larger homes requiring whole backup consider premium options from Westinghouse or DuroStar with dual fuel flexibility and higher wattage.
Always check current listings and warranties before purchasing since availability and deals change frequently online today.
