Abstract
A rechargeable apparatus is provided for being recharged by an power source. The rechargeable apparatus include a rechargeable battery and a secondary inductive coil excited by the power source. The secondary inductive coil includes a first inductor having a first axis, a second inductor having a second axis, and a third inductor having a third axis. The first, second, and third axes are mutually orthogonal. The first, second, and third inductors produce a power output in response to said power source. The secondary inductive coil is electrically connected to the rechargeable battery whereby charging energy is coupled from the power source to the rechargeable battery regardless of an orientation of the secondary inductive coil to the power source.
