A portable wire winding system includes a support frame, a spool shaft, a locking assembly, a drive shaft, and a drive assembly. The spool shaft is rotatably mounted on the support frame and includes a free end portion designed to removably support a wire spool thereon. The locking assembly is designed to detachably lock a wire spool in place on the spool shaft. The drive shaft is rotatably mounted on the support frame and includes a projection positioned at one end of the drive shaft and designed to be engaged by a rotary power tool to rotate the drive shaft. The drive assembly operatively connects the spool shaft and the drive shaft to permit transfer of rotational forces from the drive shaft to the spool shaft to rotate a wire spool on the spool shaft and wind up a length of wire.
