A portable fluid-mixing device. The fluid-mixing device comprises a container insert, an elongated shaft, a one-piece propeller, a wrench, a jam nut, and a crank. External threads of the insert are removably engageable with internal threads of an opening of a conventional 55-gallon drum. The propeller is pivotally connected to an end portion of the shaft. The wrench defines an annular surface and has external threads which are mated to internal threads of the insert. The jam nut defines an annular shoulder which is engageable by the wrench annular surface and has internal threads which are mated to the external threads of the insert, for bringing the insert into fluid-tight engagement with the drum opening. The crank, removably engageable with the shaft at the insert-carried end portion of the shaft, is used by an operator to manually rotate the propeller in the drum.
