Buying Guide for the Best Rated Inverter Generators
When choosing a rated inverter generator, you want to focus on key features that match your needs for power, portability, efficiency, and noise. Inverter generators are popular for their clean, stable electricity, making them suitable for sensitive electronics and a variety of uses, like camping, backup power, or outdoor events. The ideal model for you will depend on how much power you need, how quiet and portable you want it, and what you plan to run with it. Understanding the main specifications can help you make an informed decision and get the best fit for your situation.Rated Power (Wattage)Rated power, often measured in watts, is the amount of electricity the generator can supply continuously. This is crucial because it determines what devices you can run at the same time without overloading the generator. You will find inverter generators ranging from a few hundred to several thousand watts. For light use like charging devices or running small appliances, a lower-powered generator (800–2000 watts) is usually enough. For heavier needs, such as running power tools or a refrigerator, you may want something in the 2000–3500 watt range. Always add up the running wattage of everything you want to power to choose the right size.
Noise LevelThe noise level tells you how loud the generator will be during use and is usually measured in decibels (dB) from a certain distance. This is important for comfort and regulations in camping or residential areas. Lower noise levels (below 60 dB) are ideal for quiet environments, while 60 to 70 dB is typical for standard inverter generators and may be suited for less sensitive settings. Consider where you'll be using the generator: for campsites or tailgating, quieter is better, while noise might be less of an issue for construction.
Fuel Type and EfficiencyMost inverter generators run on gasoline, but some offer dual-fuel capabilities (gasoline and propane). Fuel type affects availability, storage, and cost. Efficiency relates to how long the generator can run on a certain amount of fuel. Typically, inverter generators are more fuel-efficient than traditional ones, giving longer run-times. Look at both the type of fuel you prefer and the claimed run-time at a given load. If you'll use your generator for extended periods, prioritize efficiency and convenient fuel.
PortabilityPortability refers to the size and weight of the generator, as well as features like carry handles or wheels. This is essential if you plan to move your generator often, say for camping, tailgating, or moving around a job site. Smaller and lighter models are easier to transport but may provide less power. Think about whether you'll need to lift and move the unit by yourself or if it will mostly stay in one place.
Clean Power (THD - Total Harmonic Distortion)Inverter generators are valued for producing 'clean' electricity with low Total Harmonic Distortion (THD). This matters especially if you're powering sensitive electronics like laptops, phones, or medical devices, which can be damaged by dirty or uneven power. A generator with THD below 5% is generally considered safe for electronics. If sensitive devices are a priority, check the THD rating or look for models marketed as safe for electronics.
Parallel CapabilitySome inverter generators can be connected with another similar unit to double the available power. This is known as parallel capability, letting you increase output when you need it, but also use a single, smaller, more efficient unit for light loads. Consider this feature if you may need to expand your power in the future without purchasing a bigger, heavier generator up front.
Outlets and ConnectivityThe number and type of outlets on a generator determine what you can plug in directly without needing extra adapters. Common connections include standard household outlets, USB ports, and sometimes RV or twist-lock outlets. Think about what kind of devices or appliances you plan to use, and make sure the generator you choose has enough and the right types of outlets for your purposes.
