Buying Guide – How to Choose the Best Cheap Gas Generator

Selecting the right generator involves balancing power needs with portability and fuel options. Consider these factors to ensure you get the right tool for your situation.

Wattage Requirements

Determine the total wattage needed by adding up the starting and running watts of the appliances you plan to power. Starting watts are often higher than running watts, so ensure your generator can handle the surge. For home backup, you might need 5000+ watts for essential circuits. For camping, 1000 to 2000 watts is often sufficient.

Always choose a generator with at least 20% extra capacity to account for surges and future needs.

Fuel Type

Gasoline is common and easy to find but has a short shelf life. Propane stores longer and burns cleaner, making it safer for indoor use with proper ventilation. Tri-fuel models let you choose between gasoline, propane, and natural gas, giving you maximum flexibility during long outages.

Consider what fuel you can store safely and access easily when choosing your unit.

Runtime and Efficiency

Look at the runtime at 50% load to see how long the generator can run before refueling. Eco modes can help extend this by adjusting engine speed based on demand. A longer runtime means less frequent refueling and more continuous power.

For emergency situations, aim for a model that offers at least 8 hours of runtime at typical load levels.

Portability and Weight

Generators range from under 30 pounds to over 300 pounds. Lighter units are easier to carry for camping but have less power. Heavier units may include wheels for transport. Check if the unit fits your vehicle trunk or storage space.

Select a weight that you can handle physically or ensures it includes wheels for easy movement.

Noise Levels

Noise is measured in decibels (dB) at 23 feet. Inverter generators are usually quieter (50-60 dB) while open frames are louder (65-80 dB). If you live in a residential area or camp near others, lower noise is a priority.

Check local noise ordinances and consider a quieter model if you value a peaceful environment.

Safety Features

Look for built-in CO sensors, low oil shutdown, and overload protection. These features prevent damage to the engine and protect users from harmful fumes. Some models also have rubber covers on outlets to prevent water damage.

Prioritize units with automatic shut-off features to ensure safe operation around your family.

Outlet Options

Ensure the generator has the outlets you need. Common options include 120V standard outlets and 30A RV outlets. Some higher wattage models include 240V for heavy-duty appliances. Check if you need transfer switches or extension cords.

Match the outlet types to your specific devices to avoid needing extra adapters or converters.

Warranty and Support

A good warranty protects your investment against defects. Look for at least a 2-year limited warranty and accessible customer support. Some brands offer lifetime technical guidance or parts coverage which adds value over time.

Review warranty terms to understand what is covered and how to claim support if issues arise.

How to Use and Care for Your Cheap Gas Generator

Before first use, check oil levels and fill with the recommended type. Do not start the generator indoors. Place it at least 20 feet away from windows or doors to prevent carbon monoxide buildup inside the house.

Run the generator on a flat surface and ensure it is not exposed to rain or moisture. Connect appliances to outlets only after the generator has stabilized. Do not overload the unit beyond its rated capacity to avoid damage.

Drain fuel or add stabilizer if storing for more than 30 days to prevent clogging. Change oil after the first few hours of use and then every 100 hours or annually. Store the unit in a dry place to extend its lifespan.
