Power droid

Power droids were unsophisticated droids that acted as ambulatory batteries, recharging vehicles and machinery. They were equipped with a small, internal power generator and several plug-in sockets.

Although they were extremely important to both military and civilian life, power droids were so commonly encountered in the galaxy that they often went unnoticed. The GNK-series by Industrial Automaton and the EG-series droid by Veril Line Systems were popular power droids. Both were commonly referred to as "gonks" due to the low honking sounds they made. Another notable model of power droid was the PLNK-series power droid that held tibanna gas; PLNK-series droids were commonly known as "plunk droids" due to their distinctive honking sound.

Apart from the EG-series, Veril Line also manufactured the miniaturized EGL power droid and ECG-series power droid. Lesser-seen models of power droid included the MPH power droid which was used by the Pyke Syndicate to power devices in the Kessel spice mines, the KT power droid utilized on Jakku and the heavily modified individual WG-22.
