Abstract

A portable power supply module with winding unit comprises a shell body, a battery room, at least one battery unit, a connection line with predetermined extension length and an output connector. The shell body is provided with a winding area and an output connector accommodation room. The battery room is provided with a set of conductive contact plates which electrically connect with a circuit board. The connection line is electrically connected with the circuit board, extended beyond the shell body and connected with the output connector. The connection line can be wound around and received in the winding area of the shell body and the output connector is accommodated in the output connector accommodation room of the shell body.

Claims

1. A portable power supply module, comprising:

a shell body, which is provided with a winding area and an output connector accommodation room, wherein the winding area is a groove laterally extending along the periphery of the shell body;

a battery room, which is formed in the interior of the shell body and provided with at least a set of conductive contact plates, wherein the conductive contact plates are electrically connected with a circuit board;

at least one battery unit, which is accommodated in the battery room to provide power through the conductive contact plates;

a connection line, having a predetermined extension length, which is connected with the circuit board, passes through the shell body and extends outside the shell body;

an output connector, which is connected to the connection line;

wherein the connection line is wound around and received in the winding area of the shell body and the output connector is accommodated in the output connector accommodation room of the shell body.

2. The portable power supply module as claimed in claim 1, wherein the output connector is a USB interface connection plug.

3. The portable power supply module as claimed in claim 1, wherein the shell body is provided with a power switch which is connected to the circuit board.

4. The portable electric energy supply module as claimed in claim 1, wherein the shell body is provided with a power indicating lamp which is connected to the circuit board.
