Need for a transfer of power?

CORD

Think about what you might plug in to connect devices and share energy.

This clue plays on the double meaning of "cord." In one sense, a cord is a physical cable needed to transfer power, like an electrical cord. The word "need" hints at the answer being a synonym or direct reference, while "transfer of power" cleverly points to the literal function of a cord. The pun works by treating "power" both as electricity and authority, making the answer fit neatly.
