Data-Con

Data-Cons are data storage devices used by the Mini-Cons. They are flat, slate-gray discs that bear the Mini-Con emblem, and can give off a glowing emergency beacon that can be seen from great distances. (This glow is virtually identical to the glow of a Mini-Con storage panel.)
Upon activation, Data-Cons emit a series of bright holographic images while relaying their data to the one who actvated them.
Data-Cons are used not only to contain data, but can also store life-sustaining energon. During the search for the Mini-Cons on Earth, the discovery of a Data-Con's energon supplies helped the Autobots pull through some tough missions.
