Inverter generators combine parts of the engine and generator which allows for the smaller size and lighter weight then older traditional models. Also they produce reliable power, as if you were plugging something in at home.
Higher fuel efficiency
All Portable Inverter Generators automatically adjust the engine speed to produce only the amount of power that is needed. Inverter generators can run on almost 40% less fuel depending on the application.
Portable Inverter generators are quieter because they do not run at full speed all the time. As they are controlled by a microprocessor then only output what is need at any given time. They are also built with sound dampening materials, to con troll the level of noise even when running at full speed/maximum load.
Can run in Parallel
Most Inverter Generators can be paired with another identically sized unit to double your power capacity. So you don't have to give up power for portability, you can now have both.
Depending on total wattage, an inverter generator can be used for many emergency situations during a home power outage.
