Abstract

A hand-held mixer includes a housing, a pillar coupled to the housing at a pillar proximal end and extending to a pillar distal end, a motor within at least one of the housing and the pillar, a first beater hub removably receiving a first beater, and a battery receptacle at the pillar distal end. The battery receptacle receives a battery pack with a battery for powering the motor such that the battery pack is operable between a docked condition and an undocked condition. In the docked condition, the battery pack is engaged with the battery receptacle to provide power to the motor. In an undocked condition, the battery pack is disengaged from the battery receptacle. The battery pack moves along a battery pack axis that is substantially perpendicular to a first beater axis of rotation from the undocked condition to the docked condition.
