Buying Guide for the Best Generator For Home Emergency

Choosing the right generator for home emergencies is crucial to ensure you have a reliable power source during outages. The right generator can keep your essential appliances running, maintain comfort, and provide peace of mind. When selecting a generator, consider the power requirements of your home, the type of fuel it uses, its runtime, and other features that can make a difference in an emergency situation. Here are some key specifications to help you make an informed decision.
Power Output (Wattage)Power output, measured in watts, indicates how much electricity the generator can produce. This is important because it determines how many and what type of appliances you can run simultaneously. Generators typically range from 1,000 watts to over 10,000 watts. For small essentials like lights and a refrigerator, a generator with 2,000 to 3,000 watts may suffice. For larger homes or more appliances, you might need 5,000 to 7,500 watts or more. Assess your power needs by listing essential devices and their wattage requirements to choose the right generator.
Fuel TypeGenerators can run on various fuels, including gasoline, propane, natural gas, and diesel. The fuel type affects the generator's runtime, availability of fuel, and maintenance. Gasoline is widely available but has a shorter shelf life. Propane is cleaner and has a longer shelf life but requires storage space for tanks. Natural gas provides a continuous supply if you have a connection, but it may not be available during certain emergencies. Diesel is efficient and has a long shelf life but can be harder to find. Choose a fuel type based on availability, storage, and your comfort with handling it.
RuntimeRuntime refers to how long a generator can operate on a full tank of fuel. This is important for ensuring continuous power during extended outages. Generators with longer runtimes reduce the need for frequent refueling. Runtime can vary from a few hours to over 24 hours, depending on the generator's size and fuel efficiency. If you expect long outages, look for a generator with a longer runtime to minimize interruptions. Consider your typical power usage and how often you can refuel when choosing a generator with the appropriate runtime.
PortabilityPortability refers to how easy it is to move the generator. This is important if you need to transport the generator to different locations or store it when not in use. Portable generators are typically smaller and have wheels and handles for easy movement. They are suitable for smaller homes or temporary use. Stationary generators are larger, more powerful, and permanently installed, providing automatic power during outages. They are ideal for larger homes or those needing a more permanent solution. Choose based on your space, power needs, and whether you need to move the generator frequently.
Noise LevelNoise level, measured in decibels (dB), indicates how loud the generator is during operation. This is important for maintaining comfort and avoiding disturbances, especially in residential areas. Generators can range from 50 dB (quiet) to over 80 dB (loud). Inverter generators are generally quieter and suitable for noise-sensitive environments. Standard generators tend to be louder but may offer more power. Consider where you will use the generator and how much noise is acceptable. If you have close neighbors or plan to use the generator near living spaces, opt for a quieter model.
Start TypeStart type refers to how the generator is started. This is important for ease of use, especially during emergencies. Generators can have manual recoil start, electric start, or automatic 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. Automatic start generators turn on automatically during a power outage, providing seamless power without manual intervention. Choose a start type based on your physical ability and preference for convenience during emergencies.
