Buying Guide for the Best Trifuel Generators

When it comes to choosing a trifuel generator, it's important to understand the key specifications that will determine how well the generator meets your needs. Trifuel generators are versatile machines that can run on three different types of fuel: gasoline, propane, and natural gas. This flexibility makes them a great choice for various situations, from home backup power to outdoor activities. To make an informed decision, you need to consider several key specifications and understand how they impact the generator's performance and suitability for your specific requirements.
Power Output (Wattage)Power output, measured in watts, indicates how much electricity the generator can produce. This is crucial because it determines what appliances and devices you can run simultaneously. Generators typically range from 1,000 watts to over 10,000 watts. For small appliances and tools, a generator with 1,000 to 3,000 watts may suffice. For larger appliances like refrigerators, air conditioners, or multiple devices, you might need 4,000 to 7,000 watts. For whole-house backup, look for generators with 8,000 watts or more. Assess your power needs by listing the wattage requirements of the devices you plan to use and choose a generator that can handle the total load.
Fuel Type and CapacityTrifuel generators can run on gasoline, propane, and natural gas, offering flexibility in fuel choice. Gasoline is widely available and provides high power output but has a shorter shelf life. Propane is cleaner-burning and has a longer shelf life but may require a separate tank. Natural gas is convenient for home use if you have a gas line but may not be available in all areas. Consider the availability and convenience of each fuel type in your area. Additionally, check the fuel tank capacity, as larger tanks allow for longer run times without refueling. Choose a generator that aligns with your preferred fuel type and offers sufficient capacity for your needs.
Run TimeRun time refers to how long the generator can operate on a full tank of fuel. This is important for planning how often you'll need to refuel during extended use. Run times can vary significantly based on the load and fuel type. For example, a generator might run for 8-12 hours on gasoline at 50% load but longer on propane or natural gas. If you need a generator for long-term use, such as during power outages, look for models with longer run times. Consider your typical usage scenarios and choose a generator that offers a run time that meets your needs without frequent interruptions.
PortabilityPortability is a key factor if you plan to move the generator frequently, such as for camping, tailgating, or job sites. Portable generators come with wheels and handles for easier transportation. The weight of the generator is also a consideration; lighter models are easier to move but may offer lower power output. If you need a generator for home backup and it will remain stationary, portability may be less of a concern. Evaluate how and where you will use the generator and choose a model that offers the right balance of portability and power for your needs.
Noise LevelNoise level, measured in decibels (dB), indicates how loud the generator will be during operation. This is important for both user comfort and compliance with noise regulations, especially in residential areas or campsites. Generators can range from 50 dB (quiet) to over 80 dB (loud). If noise is a concern, look for models labeled as 'quiet' or 'low noise,' typically producing 50-60 dB. For home use, quieter generators are preferable to avoid disturbing neighbors. Consider where you will use the generator and choose a model with an acceptable noise level for that environment.
Start TypeThe start type refers to how the generator is powered on. Common options include manual recoil start, electric start, and remote start. Manual recoil start requires pulling a cord, which can be physically demanding. Electric start uses a push-button or key, making it easier to operate. Remote start allows you to start the generator from a distance using a remote control. If ease of use is important, especially for those who may have difficulty with manual starts, consider a generator with electric or remote start. Choose a start type that matches your preference for convenience and ease of operation.
