Abstract
A cooking device includes a housing including a non-ferromagnetic surface and a lower shell positioned below the non-ferromagnetic surface. The cooking device also includes an induction cooking coil, a battery assembly configured to provide power to the induction cooking coil via a circuit board assembly, and a heat sink surrounding the battery assembly and the circuit board assembly. The induction cooking coil, the battery assembly, and the circuit board assembly are enclosed by the housing. The cooking device also includes a controller operatively coupled to the circuit board assembly and configured to switch from usage of a first driver circuit of the circuit board assembly to a second driver circuit of the circuit board assembly to power the induction cooking coil.

A cooking device, comprising:
- a longitudinal axis extending vertically through the cooking device;
- a housing including a non-ferromagnetic surface extending in a radial direction perpendicular to the longitudinal axis;
- an induction cooking coil positioned adjacent to and below the non-ferromagnetic surface;
- a battery assembly configured to provide power to the induction cooking coil;
- a heat sink including a collar having receiving walls spaced radially outward of the battery assembly;
- a circuit board assembly positioned radially outward of the battery assembly and radially inward of the collar;
- wherein at least one circuit board of the circuit board assembly is coupled to a receiving wall of the collar;
- and
- wherein the battery assembly, the induction cooking coil, and the circuit board assembly, are enclosed by the housing.
A cooking device, comprising:
- a longitudinal axis extending vertically through the cooking device;
- a housing including:
