A portable relay base is composed of an upper cover and a lower cover being oppositely joined to each other. The portable relay base at a lateral side thereof at least provides an outlet unit composed of two contact poles and/or one ground pole and at a proper position thereof provides an opening. The portable relay further comprises a power line carrier, a power line, and a circuit board. The power line carrier has a shape of disk and fits with the lower cover axially. An automatic positioning/wire collecting apparatus is provided in the power line carrier and a central hollow reel is provided at a top thereof with at least two concentric spacing rings in accordance with the number of poles of the power. The power line is a lead wire coiling around the reel as a bundle with an end thereof extending an electricity taking plug outside the opening and another end thereof having at least two conductive pieces. Both of the ends are fixedly attached to the spacing rings. The circuit board is fixed to the inner part of the upper cover with a resilient contact piece corresponding to and touching each of the conductive pieces. Once the power line carrier rotates, the power through the electricity taking plug can be delivered to each of the outlet units via at least two connecting wires.
