Abstract
An apparatus (100) for an electronic system (106), which includes a portable unit (102) and a base unit (104), supplies backup power to the base unit (104) and is capable of recharging at least one battery (121) that operates the portable unit (102). The apparatus (100) is connected in series between the base unit (104) and a main power supply (148) and includes at least one slot (131) configured to receive the at least one battery (121). When power from the main power supply (148) is available, the apparatus (100) supplies power to the base unit (104) from the main power supply (148) and is capable of recharging the at least one battery (121). When power is not available from the main power supply (148) and the at least one battery (121) is received within the at least one slot (131), the apparatus (100) supplies power to the base unit (104) from the at least one battery (121).
