“PORTABLE DEVICE FOR SUPPLYING OUTLETS INCLUDING RETRACTABLE ELECTRICAL EXTENSION CORD” consists in a body (1), on a pillar shape, with a wide base (2) in order to confer stability to the device. On the top of the body, there are outlets (6) disposed in appropriated height to supply devices positioned over an elevated surface such as a table, balcony or stand. The body contains electrical extension with mechanism of automatic retraction. Inside of the body there are two cylinders (8, 10) supported on two axes (9, 11), one in the base and another one next to the top. Both cylinders are involved by a strap (7) that contains two tracks (15) of conductive material in which are an electrical, flattened and thin cable (4) with an anti-stumbling effect. This cable (4) is rolled from one of its extremities on the strap (7), when retracted, and its opposing extremity leaves for an orifice (3) next to the base of the body, finishing in the electrical plug (5). The bottom cylinder (8) is tensioned by a spring (23) that makes the cable automatically retracts when the user desires to pick up the extension, driving the mechanism by pressing a button (2) installed on the body of the device. The top cylinder (10) has in its external surface two conductive tracks (24) that make contact with the conductive tracks (15) of the strap, whereas in the interior of the cylinder two brushes (25) of conductive material transmit the energy from the cable to the outlets supported in the top of the body, through conventional electric wires (12). The device enables several optional such as the inclusion of electrical circuit protection, electrical signal filter, DC adaptors, mobile phone chargers or cigarette lighter, in order to bring greater facility to the users, or to became more suitable for specific uses as, for example, computer equipment supplying.
