An inverter generator is a type of portable generator that produces electricity in a highly regulated and clean manner by first producing AC (alternating current) electricity, which is then transformed into DC (direct current) power, and then back to AC power with the desired level of voltage and frequency, using inverters. They are known for their fuel efficiency, quieter operation, and clean electrical output, which makes them ideal for powering sensitive electronic devices, such as laptops, smartphones, and medical equipment. They are also typically lighter and more compact than conventional generators, making them easier to transport and store.
