A rechargeable coffee or spice grinding apparatus having a grinder and a charging station. The grinder is hand portable and useable separated from the charging station. The grinder has a power supply (e.g., a battery pack) that is recharged by a current induced in the grinder's charging circuit by the inductance probe of the charging station. The charging station is cordless and plugs directly into a household wall outlet. The charging station has an inductively coupled charging probe that mates with a probe receptacle in the grinder. The charging probe induces an electrical current in the charging circuit of the grinder without any wires or direct electrical contact between the grinder to the charging station. The grinder's charging circuit connects to the rechargeable power supply and provides the electricity to operate the grinder motor. This motor is used to spin chopping blades or a burr grinder to comminute solid particulate foodstuff (such as coffee beans or spices like peppercorns) placed in the basket of the grinder. An opening on the bottom of the grinder serves as an induction receptacle for receiving the charging probe and is in electrical communication with the grinder's charging circuit. The charging station normally is supported on a flat horizontal surface, like a kitchen counter, and has a vertical component with a vertically adjustable portion having a plug end. The height of the plug may be vertically adjustable to accommodate wall plug outlets located at different heights above the kitchen counter.
