AAAAAAAAAALLLLLL ABOARD!

Conductors are glowing rod-shaped power sources used by Transformers.

Fiction

The Transformers cartoon

Wheeljack and Bumblebee stole four conductors from the Decepticons. Wheeljack believed that they wouldn't last a quartrex, but nonetheless, energy was desperately short on Cybertron, so all bits counted. The pair carried the conductors back to Iacon with all haste, managing to avoid getting offlined by the Decepticon Seekers on the way. More than Meets the Eye, Part 1

Buzzworthy Bumblebee

Perhaps we can dream of someday having rods that last at least a quartrex.

• Origin Bumblebee (Deluxe Class, 2021)

Part of the Buzzworthy Bumblebee cross-franchise subline, "Origin Bumblebee" is based on his saucer mode from "More than Meets the Eye, Part 1", and includes five conductor rods to complete the homage. However, the rods are too thick to be 5mm compatible, and as such can only be loosely held under Bumblebee's (or another character's) arm.
