Buying Guide – How to Choose the Best Cheap Gas Generator

Selecting the right gas generator involves balancing power needs budget and portability. This guide breaks down the key factors to consider so you can choose a model that fits your specific requirements.

Wattage Output

Wattage determines how many appliances you can run simultaneously. Calculate your total load by adding the running watts of all devices you want to power. For home backup aim for at least 5000 running watts to cover essential circuits.

Always choose a generator with peak watts higher than your total needs to handle startup surges from motors like in refrigerators.

Fuel Type

Most cheap generators run on gasoline which is easy to find but degrades over time. Dual fuel models can also run on propane which has a longer shelf life and burns cleaner. Tri fuel models add natural gas for infinite runtime during long outages.

Choose dual or tri fuel if you live in an area prone to long storms or fuel shortages.

Runtime Capacity

Runtime is how long the generator runs on a full tank at a specific load. Look for models with at least 8 to 10 hours at half load to reduce refueling frequency. A larger fuel tank usually means longer runtime but also adds weight to the unit.

Prioritize runtime if you need to run the generator overnight without waking up to refuel.

Noise Level

Noise is measured in decibels (dBA) at 23 feet away. Standard generators can be loud at 70 dBA or more while inverters are quieter at 60 dBA. If you camp in a campground or live in a neighborhood choose a unit under 60 dBA.

Check the noise rating carefully as it varies based on load and distance from the unit.

Portability

Weight and design affect how easy it is to move the generator. Units under 50 pounds are easy to carry by hand while heavier ones need a wheel kit. Open frame generators are lighter but less weather protected than enclosed inverters.

Consider if you need to move it daily or if it will stay in one place like a backyard.

Safety Features

Modern generators include safety features like low oil shut down and overload protection. Carbon monoxide sensors are critical for use in garages or near windows. Ensure your model has a ground fault circuit interrupter (GFCI) for outdoor safety.

Always prioritize safety features to protect both your family and your expensive electronics.

Warranty Coverage

Warranty length varies from 1 to 3 years depending on the brand. A longer warranty indicates confidence in build quality. Check what is covered such as labor and parts and if there are maintenance requirements to keep it valid.

A good warranty adds value to your purchase and ensures support if parts fail early.

How to Use and Care for Your Cheap Gas Generator

Always operate the generator outdoors in a well-ventilated area to prevent carbon monoxide poisoning. Place it on a dry level surface at least 20 feet away from your home or open windows.

Before starting check the oil level and add oil if needed since some models ship with drained oil. Connect your devices to the generator before starting the engine to ensure a smooth startup.

To maintain the generator drain the fuel or run the tank dry before long storage. Change the oil after the first 5 hours of use and then every 50 hours or as recommended by the manual.
