Inverter Generator Vs. Conventional Generators 

Unlike the other generation units, inverters produce electricity from energy-producing components. An inverter generator generates electricity by switching between two phases (DC AC to DC back to a constant AC power). 

Low harmonic distortion means it’s a reliable alternative source of electricity for sensitive appliances like smartphones. Generally, inverter generators make the most sense of converting heat into electricity. 

Conventional generators are less powerful, but they are heavier due to larger tanks. Inverters have greater fuel efficiency allowing small fuel spools or larger fuel tanks. 

We have lots more to tell you about the differences between an inverter generator and conventional generators. The upcoming sections will give you a clear distinction between the two.  

Power and Fuel Efficiency 

Conventional portable generators indeed have better power output. The mechanical difference in producing electricity and the size of the fuel tank allows the traditional generator to offer a higher output. 

One downside of these generators is that they are not fuel-efficient. It means that you’ll require more gas or fuel to power your devices and appliances. 

On the flip side, inverter generators are renowned for their excellent fuel efficiency. The production mechanism of the final AC current makes them more fuel-efficient. Unlike their traditional counterparts, they automatically adjust the engine to the load. 

Unfortunately, with the smaller fuel tanks and mechanisms, the power output of inverter generators is not as high as conventional generators.  See our review of the Cromtech portable generator.


A conventional generator can never fare up against an inverter generator when it comes to portability. Conventional generators have bigger fuel tanks, which makes them voluminous and not so space-efficient. 

Besides, the size of the conventional and inverter generators also relates to the power production capabilities. Despite its large and bulky structure, it includes wheels and handles to make it easy to manoeuvre. But, since they are almost 100 pounds or more, they are not ideal for road trips or outdoor use. 

Thankfully that’s not the case with inverter generators. Inverter generators feature a smaller fuel tank with an overall compact appearance. Besides, they are less bulky and easy to move. The standard weight of these generators ranges from 40-60 pounds, which is ideal for moving around. 

Current Noise
