A power generating device is configured to generate and transfer power to an electrical device. A sterilizable vessel is configured to accommodate the electrical device. The vessel is configured to allow power to be at least partially wirelessly transferred from the power generating device, through the vessel, and to the electrical device. An electrical device disposed within the sterilizable vessel can be wirelessly powered and/or charged, if it includes a battery. A repeater coil can be used to make the energy transfer more effective.
