Buying Guide – How to Choose the Best Cheap Gas Generator
Selecting the right generator requires understanding your specific power needs and usage scenarios.
Wattage Requirements
Determine the total wattage of appliances you need to power. Surge watts start motors while running watts sustain operation. Choose a unit with capacity exceeding your total needs by at least 20% to prevent overload.
Always calculate both surge and running watts before purchasing to ensure safety and functionality.
Fuel Type
Gasoline is common and easy to find but requires storage care. Dual or tri-fuel models offer propane or natural gas options for longer shelf life and convenience.
Consider which fuel you can reliably access and store during emergencies.
Runtime
Runtime depends on load. Higher wattage consumption shortens hours. Look for ECO mode which adjusts engine speed to save fuel.
Prioritize models with 10+ hours runtime for extended outages.
Portability
Weight varies significantly. Lighter units are easier to move but may offer less power. Wheel kits help heavy units.
Check weight if you plan to carry the unit alone.
Noise Level
Generators range from quiet to loud. Look for dB ratings below 70 for residential use to avoid disturbing neighbors.
Inverter models usually offer quieter operation.
Safety Features
CO sensors and low oil shutdowns protect users. Ensure your unit includes critical safety tech.
Always prioritize models with automatic shut-off systems.
Outlets and Ports
Check for 30A RV outlets or 240V ports if needed for appliances. USB ports add convenience for electronics.
Match outlets to your specific device requirements.
Warranty
Warranty periods vary from one to three years. Longer coverage signals confidence in build quality.
Read terms to ensure labor and parts are covered.
How to Use and Care for Your Cheap Gas Generator
Always place the generator outdoors at least 20 feet from windows and doors to prevent carbon monoxide buildup. Ensure the surface is level and dry to prevent tipping.
Check oil levels before every use and refuel when the engine is cool to avoid fire hazards. Use fresh gasoline to prevent engine clogging.
Run the generator for 15 minutes monthly to keep internal parts lubricated. Cover it when not in use to protect from weather and debris.
Frequently Asked Questions
How long does a cheap gas generator typically last?
Most budget generators last 500 to 1500 hours with proper maintenance. Regular oil changes and cleaning extend lifespan significantly. Avoid running at max load constantly to reduce wear.
Can I use a generator in the rain?
No, never operate a generator in wet conditions as water causes electrical shorts. Use a canopy designed for generators or place it under a roof overhang. Keep the area dry at all times.
What is the difference between inverter and standard generators?
Inverter generators produce clean power safer for sensitive electronics like computers. They are usually lighter and quieter but cost slightly more. Standard generators are better for heavy tools.
Do I need a transfer switch?
Yes, if connecting to home wiring, a transfer switch prevents back-feeding which endangers utility workers. For plug-in appliances, it is not required but use heavy-duty extension cords.
How do I store fuel safely?
Store gasoline in approved containers in cool, well-ventilated areas away from sparks. Rotate fuel every six months or use stabilizers to prevent degradation over time.
Why does my generator smell of gas?
This is common for new generators due to factory testing. Ventilate the area and let it run for a short time to clear odors. It dissipates quickly with normal use.
