Modern generators take pains to provide, dependable, clean power and this applies to portable generators as well. However, the basic design of the portable generator can still cause spikes and surges or allow for more harmonic distortion than some devices can handle.
This is why inverter generators are important, as they supply clean, near grid quality power and are more fuel efficient as well. When you need portable, dependable power, an inverter generator is the way to go.
In a portable generator, it is basically a process that converts mechanical energy into electrical energy. In its simplest form, as the engine shaft turns, this mechanical energy is transferred to the generator that in turns generates an electrical field.
As the mechanical energy fluctuates, so does the electrical field. While most modern portable generators are designed to minimize any fluctuation, they still do and will occur.
An inverter generator adds a process in between that converts the electric field from alternating current to direct current and then back to alternating current. This reduces those fluctuations to the point of producing very low harmonic distortion. The resulting sine wave of energy is as close to perfect as possible and therefore is very close to that of the power from the normal residential, electrical grid.
By inserting this process, it also means the engine does not have to work as hard and the engine output can be tailored to meet the demands of the load and thus it saves fuel as the entropy of the system is reduced.
In terms of a portable generator, this means less operating costs for the user and inverter generators can be scaled to demand by adding new generators instead of just buying a bigger one.

Generators are power equipment, therefore care must be taken during their operation to maintain safe running. Never attempt to refuel a hot or running generator, allowing at least 30 minutes of time to pass before adding fuel.
Always check the oil status before operation and never, under any circumstance, run a generator in an enclosed space or even a limited space such as a garage as the fumes can be lethal.
