A wrist worn battery charging system is disclosed which may be utilized to power or charge the batteries of portable devices, such as wrist worn PDA's, wrist worn Cell-Phones, wrist worn PC's, wrist worn walkie-talkies, wrist worn MP3 players, or other electronic devices which are battery powered and worn on the body of the user. The battery charger operates by turning the motion of the user's arm into electrical energy by the action of a miniature D.C. generator. The output voltage may be used to trickle charge a battery, or supply energy necessary to sustain power for the operation of a number of portable devices. The system is sealed and encapsulated to prolong its' useful life and disguise its' appearance.
