Buying Guide for the Best Generators

Choosing the right generator can be a crucial decision, especially if you need reliable backup power for your home, business, or outdoor activities. To make an informed choice, it's important to understand the key specifications and how they align with your specific needs. Here are the main factors to consider when selecting a generator.
Power Output (Wattage)Power output, measured in watts, indicates how much electricity the generator can produce. This is crucial because it determines what and how many devices you can run simultaneously. Generators come in various power ranges: small generators (up to 2000 watts) are suitable for light use like camping or powering small appliances; medium generators (2000-7000 watts) can handle multiple household appliances or tools; large generators (7000+ watts) are ideal for whole-house backup or heavy-duty equipment. Assess your power needs by listing the devices you plan to run and their wattage requirements, then choose a generator that can handle the total load.
Fuel TypeGenerators can run on different types of fuel, including gasoline, diesel, propane, and natural gas. The fuel type affects the generator's efficiency, cost of operation, and convenience. Gasoline generators are common and easy to refuel but may not be as efficient for long-term use. Diesel generators are more fuel-efficient and durable but can be noisier and more expensive. Propane generators offer cleaner burning and longer shelf life for the fuel but require a propane supply. Natural gas generators are convenient for homes with a natural gas line but are less portable. Consider the availability and cost of fuel in your area and how you plan to use the generator when choosing the fuel type.
Run TimeRun time refers to how long a generator can operate on a full tank of fuel. This is important for ensuring continuous power during outages or extended use. Generators with longer run times are more convenient as they require less frequent refueling. Run times can vary widely: small portable generators may run for 4-8 hours, while larger models can run for 10-24 hours or more. Think about how long you need the generator to run without interruption and choose a model that meets those needs.
PortabilityPortability is a key factor if you need to move the generator frequently or use it in different locations. Portable generators are designed with wheels and handles for easy transport, making them ideal for camping, outdoor events, or job sites. Stationary generators, on the other hand, are permanently installed and provide automatic backup power for homes or businesses. Consider how and where you will use the generator to determine if portability is a priority for you.
Noise LevelNoise level, measured in decibels (dB), indicates how loud the generator will be during operation. This is important for comfort and compliance with local noise regulations. Generators can range from very quiet (50-60 dB) to quite loud (70-90 dB). Quiet generators are ideal for residential areas, camping, or events where noise is a concern. Louder generators may be acceptable for construction sites or remote locations. Consider where you will use the generator and how much noise is acceptable in that environment.
Start TypeGenerators can have different start types, including 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. Choose a start type based on your preference for convenience and ease of use. Electric and remote starts are generally more user-friendly, especially for those who may have difficulty with manual starts.
Inverter TechnologyInverter generators produce cleaner and more stable power, making them suitable for sensitive electronics like computers and smartphones. They are also typically quieter and more fuel-efficient than conventional generators. Inverter generators are ideal for camping, tailgating, or any situation where you need reliable power for electronic devices. If you plan to power sensitive equipment, consider investing in an inverter generator for its superior power quality and efficiency.
