How Long Do Inverter Generators Last?

how long do inverter generators last

Inverter generators have several advantages over traditional generators, including long runtimes, fuel efficiency, cleaner power, and lower noise. Some models have extra-large fuel tanks that can keep them running for up to 18 hours. They are also quieter, making them safer for sensitive electronics.


The runtime of an inverter generator is how long the generator will provide power once its fuel tank is full. A portable inverter generator with a smaller fuel tank will run for a shorter period of time, while larger generators will last longer. Consider the amount of fuel you can carry and your use before purchasing an inverter generator.

The average runtime of an inverter generator is six to eight hours. More powerful models can last up to 22 hours. Inverter generators can use gasoline, natural gas, or propane to produce power.

Fuel consumption

Fuel consumption of inverter generators is comparatively low compared to conventional generators. The reason is that inverter generators work more efficiently and require less fuel. Moreover, inverters throttle down their engine when the load is low, thereby saving fuel and reducing noise.

In addition to being more fuel efficient, inverter generators are also quiet and lightweight. They are a better choice if you are using your generator for recreational activities or for powering sensitive electronics in case of an outage. However, you may need to spend a little more on an inverter generator if you are a frequent camper and want to run your RV and other major appliances.

Cleaner power

Cleaner power is important for the proper functioning of electronics. This is because most household products use a microprocessor or other advanced electronic circuitry that is sensitive to the quality of the electricity. Unclean power can damage the electronics and cause them to malfunction. Inverter generators provide clean power.

An inverter generator generates clean AC electricity through combustion of fuel. It then rectifies this power into a DC electric current with the help of capacitors. The DC current is then inverted back to AC power. The resulting power is cleaner and has a lower total harmonic distortion than traditional generators. This lower level of harmonic distortion means that it is safe for sensitive electronics.


When it comes to inverter generators, you want a long-lasting unit. Typically, a 700-watt unit will last for eight to 10 hours of run time. However, some models feature extra-large fuel tanks and can run for up to 18 hours. This means that you won’t need to fill the tank every time you need to use the generator. Another benefit of an inverter is that it is quieter than other types of generators, making it safe for sensitive electronic equipment.

If you regularly experience power outages, it may be better to invest in a larger home standby or portable generator. However, an inverter generator is an excellent choice for recreational purposes and in areas where noise is a consideration.


Inverter generators have a lot to offer. For instance, they can provide clean and stable power, which is necessary for sensitive electronic devices. These devices will last longer if they are provided with clean power and a stable voltage. In addition, inverter generators can handle much more complex tasks than conventional portable models. But they are also more expensive than their conventional counterparts.

Because of these technical advantages, inverter generators have higher prices than other generators. However, competition is likely to drive down prices over time. However, one disadvantage is that they have a lower surge rating than traditional generators, which means they are not suited for air conditioners or dryers. However, they are useful for powering many appliances in commercial kitchens.
