A first electronic device includes an inner inductive coil positioned at least partially around a shield core and a second electronic device includes an outer inductive coil positioned around an aperture. The first electronic device is operable to receive power from and/or transmit power to the second electronic device when a portion of the first electronic device is inserted into the aperture of the second electronic device, positioning the inner inductive coil within the aperture and within the outer inductive coil. When power is being transmitted between the first and second electronic devices, the shield core concentrates magnetic flux around the inner inductive coil and/or the outer inductive coil. In some implementations, an outer shield may be positioned at least partially around the outer inductive coil and may also concentrate magnetic flux around the inner inductive coil and/or the outer inductive coil.
