Power generators are machines designed with the ability to produce power. Eksoan manufactured certain power generators, for instance, the Class-4T3 power generator and the Class-5B1 duplex power generator. Certain types of generators could create sufficient energy to supply power to an entire colony. However, other generator designs were significantly smaller and used to energize vehicles; an example is the Moll K-19 power generator that provided power for Joben T-85 speeder bikes. When in operation, these generators could be readily found via scanners. Furthermore, power droids, which functioned as mobile power storage units, included a compact power generator inside their structure.
