Buying Guide for the Best Dual Fuel Generator

Choosing the right dual-fuel generator can be a bit overwhelming, but with the right approach, you can find the perfect model to suit your needs. Dual-fuel generators are versatile machines that can run on both gasoline and propane, offering flexibility and convenience. When selecting a dual-fuel generator, it's important to consider several key specifications to ensure it meets your power requirements and usage preferences. Here are the key specs to focus on and how to navigate them.
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 light use, such as powering small appliances or tools, a generator with 1,000 to 3,000 watts may suffice. For more demanding needs, like running multiple household appliances or larger tools, look for models in the 4,000 to 7,000-watt range. For whole-house backup or heavy-duty use, consider 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 Capacity and RuntimeFuel capacity refers to the amount of fuel the generator can hold, while runtime indicates how long the generator can operate on a full tank of fuel. This is important for determining how often you'll need to refuel during extended use. Generators with larger fuel tanks offer longer runtimes, which is beneficial during power outages or for prolonged outdoor activities. For occasional use or short-term power needs, a smaller fuel tank with a shorter runtime may be sufficient. For continuous or emergency use, opt for a generator with a larger fuel tank and longer runtime to minimize the frequency of refueling.
PortabilityPortability is a key factor if you plan to move the generator frequently or use it in different locations. This includes the generator's weight, size, and whether it has wheels and handles for easy transport. Lightweight and compact models are ideal for camping, tailgating, or occasional use around the house. Heavier models with wheels and handles are better suited for more permanent installations or frequent relocation. Consider how and where you'll use the generator to determine the level of portability you need.
Noise LevelNoise level, measured in decibels (dB), indicates how loud the generator will be during operation. This is important for ensuring comfort and compliance with noise regulations, especially in residential areas or campsites. Generators typically range from 50 dB to over 80 dB. For quiet operation, look for models with noise levels below 60 dB, which are comparable to normal conversation. For less noise-sensitive environments, generators with noise levels up to 70 dB may be acceptable. Consider where you'll be using the generator and how important noise reduction is for your situation.
Starting MechanismThe starting mechanism refers to how the generator is turned 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 and more convenient. Remote start allows you to start the generator from a distance using a remote control. If ease of use is a priority, especially for those who may have difficulty with manual recoil, opt for an electric or remote start model. Consider your physical ability and convenience preferences when choosing the starting mechanism.
Outlets and ConnectivityOutlets and connectivity options determine what devices and appliances you can plug into the generator. This includes the number and types of outlets, such as standard household outlets, 30-amp or 50-amp RV outlets, and USB ports. More outlets and diverse types offer greater flexibility in what you can power. For basic use, a few standard outlets may be sufficient. For RVs, construction sites, or more complex setups, look for generators with specialized outlets and higher amperage. Assess your power needs and the types of devices you'll be using to ensure the generator has the appropriate outlets and connectivity options.
