The Kimmunicator is a multipurpose communications and computing tool used by Kim Possible.
The Kimmunicator is a hand-held device, approximately the size of a PDA or palmtop computer. It has a relatively large color screen taking up about half of its face. Several ports for sensors and cameras can be found on the housing. It is constructed of unknown materials, likely high-impact plastic, and is a pale blue in color. A Kimmunicator watch that replaced the old one debuted in Odds Man In, according to the production code, and it looks similar to the time-traveling watch Kim used in A Sitch in Time. It can also unlock state of the art security systems, though it primarily acts as a conduit for Wade to hack into said systems in the cases it does.
Its primary role is as a communications link between Kim and Wade, and this is the function seen most often. It seems large for the job, given the compact nature of the modern cellular phone, but it is a marvel of miniaturization given all it can do apart from just communicate. In addition to the usual smartphone options, it has two-way video, serves as a sensor device, a jamming frequency generator, a camera, and has several self-mobility functions, including wheels, skis, and the ability to fly on its own.
Most of its functions are activated remotely by Wade, but Kim is able to use some of them herself. It is not known if the device has all these functions at the same time: the Kimmunicator has been lost or destroyed several times in Kim's career, but it was always replaced soon after; thus, it is possible the replacement units had upgraded abilities.
The Kimmunicator is a unique item, created by Wade just for Kim, and undergoes regular upgrades. It is powered by a trilithium power cell, an advanced super-battery that can carry enough charge to power much larger devices such as Drakken's brain switch machine in Mind Games. This battery lasted almost four years before needing to be replaced, under even the extreme abuses to which it was subjected.
Kim's First Kimmunicator
Kim's Second Kimmunicator
After A Very Possible Christmas, Wade sent Kim a replacement, which she used until the middle of Season 4.
Kim's Third Kimmunicator
After her Kimmunicator was destroyed and lost many times, Kim was given a Wristwatch Kimmunicator, placed on her left wrist. This Kimmunicator has a built-in grappling hook, magnet, and possibly everything the old Kimmunicators had. She used this one permanently throughout the rest of the series.
