A portable device may be carried by the user, in one preferred embodiment thereof, and motorizes the task of opening beverage containers having a screw cap. The mechanism that couples to the bottle cap consists of a generally circular band having a distal end bent inwardly in the direction of the cap. The bend of the band is sized and configured to permit receipt of the bottle cap with the bent tang of the band engaging the periphery of the bottle cap at one location. The band is mechanically coupled to the drive shaft of a drive motor with the drive shaft extending axially of the band. The drive motor is mounted on a plate carrying a strap designed to receive fingers of the user so that the user may grasp the plate. An activation switch is conveniently located on the plate so that it may be operated by a knuckle or finger of the user. In a second embodiment, the mechanism may be mounted on a bracket mounted, for example, on a bar, with the motor shaft facing downwardly depending from the motor, and with the band located below. In a further modification, the band may be provided with a stepped configuration having regions of differing sizes so that bottles having caps of differing dimensions may all be opened using the subject device.
