How to Buy the Best Quiet Portable Generator
1. Noise level
Quiet portable generators aim at maintaining the lowest noise level possible. Your portable generator can be categorized as quiet it contains its noise level below 60 dBA at 25% loads.
Many of the quiet portable generators we reviewed have noise levels between 50 dBA and 60 dBA. Some have even lower noise levels.
Since you’ll be using your portable generator at home or outdoor, you want on that causes little to no interference and discomfort to other people or the environment from the noise it produces.
The portability of your quiet generator will depend on factors such as weight, size, and features installed to support mobility.
Since portable inverter generator can weigh over 100 pounds, those weighing less than 50 pounds can be considered lightweight and highly portable.
Some features that may enhance the portability of your quiet generator include uniquely-shaped handles, wheels, and compact sizes.
Larger generators come with wheels, which make the inverters portable despite their bulkiness.
3. Peak/Rated watts
The power of your quiet portable generator will be represented in peak watts and rated watts.
Peak watts represent the total power your generator produces during an instantaneous surge, such as when it is starting. Rated watts represent the continues running power that your generator produces.
Peak watts tend to be more than rated watts, so if your generators power reads 3500W/3000W, for instance, the first part is the peak power, while the second one is the rated power.
The higher the running watts, the more appliances your generator can power.
Your quiet portable generator is powered by a gasoline engine, whose displacement is measured in centimeters cubed (cc). The more the cc of your engine, the more powerful it is.
The engine will also have a fuel tank of a given capacity such as 1 gallon, which has an impact on the generator’s total run time.
Generators that combine powerful engines of over 100cc and high-capacity fuel tanks of over 2 gallons tend to have run times exceeding 10 hours.
5. Run time
As noted above, the run time of your portable generator will be mostly determined by the engine strength and fuel tank capacity.
However, factors such as load can also have an impact on how long the generator runs.
While most portable inverter generators have a run time of between 6 hours and 10 hours at 25% loads, others have run times longer than 10 hours because of their more powerful engines.
You can always extend the run time of your generator by reducing the number of appliances it is powering.
6. Clean output (Outlets)
The number of outlets producing clean output from your generators is important. Heavy-duty portable generators have multiple outlets.
You may get a generator that has 120V RV receptacles, 120V household receptacles, 5V USB slots, and 12V DC outlets. All these are clean-output options you can choose from.
The clean output is made possible by reducing the generator’s total harmonic distortion (THD) to a maximum of 5% or lower, thus safeguarding sensitive appliances.
7. Extra features: auto start, low oil shut-off; variable engine speed
There are some extra features in a quiet portable generator that makes it easy to use, more fuel-efficient, and easier to maintain.
For example, an auto-start or remote start is a feature that allows you to start your generator remotely through a remote device.
If the oil in the generator’s engine is running low, the auto shut-off feature turns off the engine automatically to prevent damage.
Variable engine speed controls the engine dynamically depending on the load being supported, thus improving fuel economy and extending engine life.
When shopping for your quiet portable generator, confirm that the peak and rated watts are enough to support all the appliances you will be. Portability is also important, as is noise level, and run time.
If budget is not an issue, then get the Honda EU2200i, which emerged as best overall quiet portable generator for its exceptionally low noise levels, low weight, and superior build quality.
