[2] AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves.
Consumer electronics usually include an AC adapter (a type of power supply) to convert mains-voltage AC current to low-voltage DC suitable for consumption by microchips. Consumer voltage converters (also known as "travel converters") are used when traveling between countries that use ~120 V versus ~240 V AC mains power.

Small, detached power supplies for consumer electronics are called AC adapters, or variously power bricks, wall warts, or chargers.
The list includes technologies that were first posited in non-fiction works before their appearance in science fiction and subsequent invention, such as ion thruster. To avoid repetitions, the list excludes film adaptations of prior literature containing the same predictions, such as " The Minority Report ".

The vocabulary includes words used in science fiction books, TV and film. A second category rises from discussion and criticism of science fiction, and a third category comes from the subculture of fandom. It describes itself as "the first historical dictionary devoted to science fiction", tracing how science fiction terms have developed over time.
Adaptations have included stage shows, a "trilogy" of five books published between 1979 and 1992, a sixth novel penned by Eoin Colfer in 2009, a 1981 TV series, a 1984 computer game, and three series of three-part comic book adaptations of the first three novels published by DC Comics between 1993 and 1996.
