Abstract
A human-powered slim charger utilizing an axial flux alternator for converting a pull-out motion into an electrical current for charging and supplying battery-fed electronic devices. The charger comprises mechanical transmission means for converting a periodic linear movement into a unidirectional rotation, an axial flux alternator comprising a stator comprising a planar winding, having a plurality of coils embedded in multiple layers within said stator and circularly distributed around a central axis and two essentially identical rotors arranged to rotate together around said central axis and allocated concentrically with said winding on both sides of said stator facing each other; wherein each said rotor comprises a periodical heteropolar axially magnetized magnetic system having a definite number of poles; Finally, the device comprises a charging control module affixed to the stator, said control module configured effectively convert non-stable alternating current produced by said alternator into a charging direct current.
