GNK power droids were effectively power generators with legs and simple artificial intelligence so they could understand rudimentary commands. They were most commonly found on under-developed worlds that did not have an expansive power grid, or in mobile military operations.
They often made a low honking noise that sounded like the word "gonk," resulting in the nickname gonk droids or simply gonks. This form of droidspeak was referred to as "Gonkian."
Some Droid Chips contain over 70 sounds.
