An apparatus (100) that charges a portable electronic device having a rotatable housing is disclosed. The apparatus can include a first portable electronic device housing (110) and first selective call receiver circuitry (121) contained within the first portable electronic device housing. The apparatus can also include a second portable electronic device housing (115) rotatably coupled to the first portable electronic device housing, where the second portable electronic device housing can be rotatable (118) about an axis of the first portable electronic device housing. The apparatus can also include second selective call receiver circuitry (122) contained within the second portable electronic device housing, where the second selective call receiver circuitry can be coupled to the first selective call receiver circuitry. The apparatus can also include a battery (190). The apparatus can also include an integral electric generator (180) coupled to the first portable electronic device housing, coupled to the second portable electronic device housing, and coupled to the battery, where the integral electric generator can be configured to charge the battery based on rotation of the first portable electronic device housing relative to the second portable electronic device housing.
