Abstract: A device for inductively charging an electronic accessory includes a first portion, a second portion, and a spacer. The first portion includes a first transmission coil in a first plane where the first transmission coil is configured to generate a first magnetic field, and the second portion includes a first transmission coil in a second plane where the second transmission coil is configured to generate a second magnetic field. The spacer is positioned between the first transmission coil and the second transmission coil and between the first plane and the second plane. The spacer material magnetically insulates the second transmission coil from the first magnetic field.
