Abstract
An inductive charger comprising an inductive coil and a chargeable power pack. The inductive charger includes a driving circuit connectable to the power pack for providing a varying electrical potential to the inductive coil such that the inductive coil is inductively couplable to a secondary coil wired to an electrical load. The inductive charger may further include a charging circuit for connecting the inductive coil to the power pack when the inductive coil is inductively coupled to a primary coil.
