Inverter generators produce cleaner, smoother electrical signal than which is safer for electronics and sensitive equipment like phones and computers. This is done by producing an AC current, converting it to DC and then converting it back to AC.
Inverter generators in general tend to use less fuel and are quieter than their conventional counterparts by producing electricity on-demand. This because they only produce the electricity that your devices require from the inverter generator at thqt time. With the lower power requirements, the engine can run at slower speeds with less noise and fuel consumption.
