The Best Long Running Generator of 2023

Generators are essential devices that provide power when you need it most, whether during power outages, outdoor events, or on remote job sites. When searching for a generator, one of the key considerations is its runtime, or how long it can operate continuously on a single tank of fuel.

In this comprehensive guide, we’ll explore the factors that affect a generator’s runtime, provide tips on finding a long-running generator, and discuss the various types and features to consider for your specific needs.

Understanding Generator Runtime

Before delving into how to find a long-running generator, it’s crucial to understand the factors that impact runtime:

  1. Fuel Type: The type of fuel your generator uses significantly affects runtime. Common options include gasoline, propane, diesel, and natural gas.
  2. Fuel Capacity: A generator’s fuel tank size dictates how much fuel it can hold. A larger tank typically results in longer runtime.
  3. Fuel Efficiency: The generator’s engine efficiency plays a significant role. More efficient engines consume less fuel, extending runtime.
  4. Load Size: The electrical load placed on the generator influences runtime. Lighter loads consume less fuel and allow for longer operation.

Step 1: Assess Your Power Needs

Before you begin your search for a long-running generator, assess your power requirements. Determine the essential appliances and devices you want to power during an outage or event. Make a list of both essential and non-essential items to estimate your total wattage needs.

Step 2: Choose the Right Fuel Type

Selecting the appropriate fuel type is crucial. Consider the pros and cons of each:

  • Gasoline: Widely available but can degrade over time.
  • Propane: Clean-burning fuel with a longer shelf life.
  • Diesel: Highly efficient but typically used in larger generators.
  • Natural Gas: Provides a constant fuel supply but may require a gas line.

Choose the fuel type that best suits your preferences and availability.

Step 3: Determine Runtime Requirements

Calculate the runtime you need based on your power needs and expected duration of use. If you anticipate long outages or extended outdoor events, prioritize generators with longer runtimes.

Step 4: Research Generator Types

Generators come in various types:

  • Portable Generators: Suitable for temporary use and outdoor activities.
  • Inverter Generators: Deliver clean and stable power, ideal for sensitive electronics.
  • Standby Generators: Automatically start during power outages and provide continuous backup power.

Select the type that aligns with your intended use.

Step 5: Consider Fuel Efficiency

Review the fuel efficiency of different generator models. Look for generators with technologies like automatic idle control, which reduces fuel consumption when the load is light, extending runtime.

Step 6: Check Fuel Tank Capacity

Generator fuel tanks vary in size. Opt for a generator with a larger tank if you require longer runtime without refueling interruptions.

Step 7: Explore Additional Features

Modern generators offer various features to enhance convenience and performance:

  • Electric Start: Simplifies the startup process.
  • Fuel Gauge: Provides real-time fuel level monitoring.
  • Low-Oil Shutdown: Protects the engine from damage.
  • Multiple Outlets: Accommodates different devices.

Evaluate these features to find the generator that suits your needs.

Step 8: Read Reviews and Compare Brands

Research generator brands known for their reliability and durability. Read customer reviews to gain insights into real-world performance and any issues users have encountered.

Step 9: Calculate Total Cost

Consider not only the generator’s purchase price but also ongoing costs, including fuel, maintenance, and potential installation expenses for standby generators.

Step 10: Seek Professional Advice

If you’re unsure about the right generator for your needs, consult a professional electrician or generator expert. They can assess your requirements and recommend suitable options.


Finding a long-running generator involves a thorough assessment of your power needs, fuel preferences, and runtime requirements. By following the steps outlined in this guide, you can select the ideal generator that provides reliable power for extended periods.

Whether you need backup power during outages or a dependable energy source for outdoor activities, a long-running generator ensures you have the electricity you need when it matters most.
