Abstract

Self powered cell phones are provided with an armature which is supported to freely oscillate in swinging opposite motions and which includes a wire coil configured to intersect the magnetic flux of a permanent magnet during such motions, which generates electrical voltage and current that can be used to operate the phone or charge or recharge its batteries. Recharging mechanisms are manually or flywheel operated to impart the armature's motions and supply the generated current to the cell phone batteries.
