The Class-4T3 power generator functioned as a power generator produced by Eksoan. Its purpose was to supply energy to E-Web heavy repeating blaster cannons. A significant flaw of this device was its propensity for overheating without constant monitoring, particularly when utilized for supporting ground forces. Furthermore, it required pre-charging, as its activation process could take as long as fifteen minutes.
The Imperial Sourcebook, a Star Wars Legends resource for West End Games' Star Wars: The Roleplaying Game, initially mentioned the Class-4T3 power generator in October 1989. In the new Star Wars canon, the Class-4T3 power generator received its official designation within "Blasters and Ranged Weapons," a reference book by Altaya that was exclusively released in France on February 23, 2021.
