Power supply device and system having an induction cooking appliance and a power supply device

A system comprising:

• an induction cooking appliance comprising a support surface for supporting a cooking vessel thereon, and an induction coil that is operable to heat the cooking vessel when supported on the support surface;
• and
• a power supply device for supplying power to an electrical device,
• wherein the system is configurable to assume a power supply configuration in which the power supply device rests on the support surface adjacent to the induction coil, and the induction coil is operated to generate an electromagnetic field, and
• wherein the power supply device comprises:
• a receiving coil configured to interact with the electromagnetic field generated by the induction coil when the system is in the power supply configuration, wherein the receiving coil is configured to generate an electrical energy signal in function of the electromagnetic field,
• a conversion unit operatively connected to the receiving coil and configured to convert the electrical energy signal into an output signal, and
• an output interface operatively connected to the conversion unit and configured to be connected to the electrical device and to provide the output signal to the electrical device.
