Power chip rectifier
Power chip rectifiers are a piece of Transformer anatomy which gives its possessor special powers that other Transformers do not have.
Fiction
In a plot to defeat Optimus Prime in a one-on-one battle, Megatron had the Constructicons build a device that would siphone off all the unique special powers of his Decepticon warriors and transfer them into his own body. In order for the machine to work, each Decepticon had to remove their power chip rectifier and place it within the machine. Starscream lamented that without his power chip rectifier he could not perform any of his special abilities, including his cluster bombs and his null ray.
