A comlink is a small, hand-held personal communications transceiver. It consists of a receiver, a transmitter, and a small power source. Comlinks vary in size and configuration from hand-held cylindrical models to flat wrist-mounted units, to units incorporated into armored helmets.

The comlink used by Jedi Master Qui-Gon Jinn has a port built into its base for transmitting data gathered by other devices, such as a sampler used to examine midi-chlorian levels.
