The invention is a recharger device having an efficiently designed base charging unit and at least one rechargeable handheld implement, which also serves as an advertising means. The base unit has two electrical prongs on the rear surface and at least one orifice on at least one outer surface of the base unit, each of which lies completely within the surface where it lies. The base unit is shaped and the electrical prongs are positioned and oriented such that when the recharging base is inserted into one socket of a common two socket electrical outlet, the second socket is not blocked by the base unit, thereby permitting both sockets to be fully utilized.

A battery charger supporting 3C (computer, communication, consumer electronics) products such as a mobile telephone, a PDA, a notebook computer, a digital camera, a digital video camera, etc. The battery charger is constructed to include a body, a circuit board, a reel assembly, an outlet lead wire, a rotable reel, a securing axle, a slide switch, and a two-pinned plug. Apart from a terminal at one end of the retractable outlet lead wire being adapted to enable connecting to a jack of a mobile phone and thereby charge the mobile phone, the battery charger is also configured with a battery recess that supports inserting of a mobile phone battery therein, whereby charging of the mobile phone battery can be accomplished.

A power source having a housing is disclosed. A first power cord extends from the housing. The first power cord has a first connector positioned at a distal end thereof for selective connection to an external power source. A second power cord extends from the housing. The second power cord having a second connector positioned at a distal end thereof for selective connection to an electronic device. A power adapter is connected between the first and second power cord. Upon connecting the external power source, the power adapter detects the presence of and receives external power through the first power cord and transfers power to the electronic device through the second cord. The power adapter also retains a charge therein for providing power to the electronic device when no external power source is detected.

A multiple-in-one retaining seat comprises a retaining seat; two lateral front sides of the retaining seat being installed with two frames; a lower side of the center of the retaining seat being installed with a receptacle for receiving the personal digital assistant; an interface cartridge inserted in the retaining seat for transferring received signal to the personal digital assistant through the retaining seat; a circuit board installed in an embedding groove at an upper end of the backside of the retaining seat; the circuit board being connected to a slot seat; a lateral side of the embedding groove being protruded with a mask for receiving a speaker; the speaker being electrically connected to the circuit board for providing a hand free function; a slot being formed in the slot seat for receiving the interface cartridge; and two guide posts are installed on the retaining seat for positioning the interface cartridge.

A mobile battery charging pack includes a casing, which has positive and negative electrodes for the connection of a battery set, a plurality of power input/output terminals respectively electrically coupled to the battery set, and a power control switch that controls the connection between the power input/output terminals and the battery set and the function of the power input/output terminal for power into to charge the battery set with external power supply or to charge the battery of an external mobile electronic device with the battery power supply of the battery set.
