Abstract
A rewindable electrical cable extension device includes a housing having first and second exit ports, and a cable having first and second ends defining opposing extremities of first and second contiguous cable sections having a common junction anchored to a rotating spool. The first end protrudes through the first exit port, and the second end is fixedly mounted in association with the second exit port. The first cable section is wound on a spool that is configured to rotate within the housing. The second cable section is wound in an opposite direction to the first section so that pulling on the first end unwinds and extracts the first cable section from the housing and uncoils the second cable section within the housing without rotating the second end of the cable.
