Abstract
A charger cradle used for charging a battery of a portable electrical device. An electromagnetic device is disposed within the charger cradle proximate a metal piece of the cordless handset when the cordless handset is placed in a receiving portion of the charger cradle. The electromagnetic device generates a magnetic field when charge contacts of the charger cradle and the cordless handset are in contact and a charging current is conducted from a charging circuit of the charger cradle. The magnetic field attracts the metal piece of the cordless handset and securely holds the cordless handset into the receiving portion while the charging circuit charges the battery of the cordless handset.
