Pip-Boy

The RobCo Pip-Boy is a personal information processor manufactured by RobCo Industries.

Background
Pip-Boys were issued to Vault-Tec Corporation vaults. The version of the device varied by vault, and certain Pip-Boy models could support additions and equipment that other models could not. Usage of Pip-Boy was not exclusive to vaults, as members of the Free States utilized them, and the RobCo Auto-Caches were meant to require such devices. Elijah comments on its usefulness before and after the Great War, calling it a "convenience" and a "crutch."

Appearances
Pip-Boys appear in Fallout, Fallout 2, Fallout 3, Fallout Tactics, Fallout: New Vegas, Fallout 4, and Fallout 76.
