Buying Guide – How to Choose the Best Cheap Gas Generator

Selecting the right generator involves balancing power needs, fuel type, portability, and budget to ensure reliable performance for your specific situation.

Wattage Requirements

Determine the total wattage needed to run your essential appliances during an outage. Add up the running watts of all items you plan to power and select a generator with peak and running watts that exceed this total to handle startup surges.

Prioritize a unit that meets or exceeds your calculated needs to avoid overloading and ensure all devices run safely without tripping breakers.

Fuel Type and Capacity

Generators run on gasoline, propane, or natural gas. Gasoline is common but may spoil; propane stores longer. Consider dual or tri-fuel options for flexibility. Fuel tank size dictates runtime, so larger tanks mean fewer refueling breaks.

Choose a fuel type that matches availability and storage options, and select a tank size that supports the runtime you expect during typical outages.

Portability and Weight

If you need to move the generator frequently, weight is critical. Lighter units under 50 lbs are easier to carry but may offer less power. Look for wheel kits and handles if you need to move a larger unit across yards or job sites.

Balance weight against power needs; a heavier unit is better for home backup, while a lighter one suits camping or tailgating where mobility matters.

Noise Level

Noise is measured in decibels (dBA) at 23 feet. Inverter generators tend to be quieter than open frame models. For camping or residential use, aim for units under 60 dBA to avoid disturbing neighbors or wildlife.

Check the noise rating and choose an inverter or enclosed model if silence is a priority for your usage scenario or local regulations.

Safety Features

Look for essential safety features like low oil shutdown, overload protection, and CO alerts. CO sensors are vital for preventing poisoning by shutting down the unit if fumes build up. Ensure the generator has GFCI outlets for protection against electrical shock.

Prioritize models with CO alerts and proper grounding features to ensure safe operation, especially when using the generator near enclosed spaces or windows.

Outlets and Compatibility

Check the number and type of outlets. Standard 120V sockets are common but RVers need 30A or 50A outlets. Ensure the generator has enough outlets to connect all your devices without needing unsafe extension cords or splitters.

Select a unit with the specific outlets you need for your devices, ensuring compatibility with RV plugs or heavy appliance cords if applicable.

Runtime and Efficiency

Runtime varies based on load. ECO modes help extend runtime by reducing engine speed when demand is low. Look for models that offer at least 8 to 10 hours of runtime at half load to ensure coverage during long outages.

Prioritize generators with fuel-efficient engines or ECO modes to get the most power per gallon of fuel, reducing refueling frequency during emergencies.

Warranty and Support

A good warranty indicates manufacturer confidence. Look for at least a 2-year limited warranty covering parts and labor. Check if technical support is available and if the brand has a network for repairs or service.

Verify warranty terms and support availability before buying to ensure you can get help quickly if issues arise after purchase or during heavy use.

How to Use and Care for Your Cheap Gas Generator

Always place the generator outdoors on a flat, dry surface away from windows and doors to prevent carbon monoxide buildup. Never run it indoors or in garages even with doors open.

Follow the manufacturer instructions for oil and fuel. Use fresh gasoline with stabilizer if storing, and mix oil properly for 2-stroke models. Check oil levels before every use.

Run the generator under a light load to warm it up before connecting heavy appliances. Let it cool down before refueling. Store fuel in approved containers away from living areas.
