Buying Guide – How to Choose the Best Cheap Gas Generator

Selecting the right cheap gas generator requires balancing cost with essential features that match your specific power needs and usage scenarios.

Wattage Requirements

Wattage determines what appliances you can run during an outage. Calculate the starting and running watts of your essential devices to ensure the generator can handle the load without overload.

Always choose a generator with a peak wattage higher than your total running needs to accommodate startup surges from motors and compressors.

Fuel Type and Capacity

Fuel types include gasoline propane and natural gas with dual fuel offering flexibility. Capacity affects runtime so check how long the tank will last at your expected load level.

Larger tanks mean longer runtimes but add weight and size to the unit.

Runtime and Efficiency

Runtime is the duration a generator runs on a full tank at a specific load. Look for models with ECO mode which adjusts engine speed to save fuel during low usage.

Higher efficiency means fewer refueling stops during long outages which is crucial for convenience.

Noise Levels

Noise is measured in decibels dBA and varies by enclosure type. Inverter generators are typically quieter than open frame models making them better for campsites.

Choose units under 60 dBA if you need quiet operation near neighbors or for sensitive environments.

Portability and Weight

Portability depends on weight and handle design. Smaller units under 50 lbs can be carried easily but heavier models may need wheels.

Check if wheel kits are included if you plan to move the generator frequently across uneven ground.

Safety Features

Safety features like low oil shutdown protect the engine from damage while CO sensors prevent carbon monoxide poisoning. These are vital for indoor adjacent use.

Prioritize models with automatic shutoff systems to prevent accidents during operation.

Outlet Types

Outlets must match your appliance plugs such as 120V standard or 120/240V twist locks. RV ready outlets are essential for campers needing 30A connections.

Ensure the generator has enough outlets for your needs or consider models with parallel capability.

Warranty and Support

Warranties range from 1 to 3 years and cover parts or labor. Reliable support ensures you can get help if issues arise with the engine.

Look for brands offering extensive support networks to guarantee long term reliability.

How to Use and Care for Your Cheap Gas Generator

Always place the generator outdoors in a well ventilated area to prevent carbon monoxide buildup. Never use it inside a garage even with windows open due to toxic gas risks.

Check oil levels before every use and use fresh fuel to avoid engine damage. Add fuel stabilizer if storing for more than 30 days to keep the system clean.

Run the generator for a few minutes weekly to keep the engine lubricated and ready for emergencies. Cover it with a breathable waterproof cover to protect against dust and rain.
