`BACKGROUND OF THE INVENTION
`
`BRIEF DESCRIPTION OF THE DRAWINGS
`
`1. Technical Field
`The present invention relates to external power supply for
`consumer electronics, and more particularly, to a power-Sup
`plying device adaptive to connect a portable electronic device
`and act as a backup power source that provides a variable
`power capacity.
`2. Description of Related Art
`Currently, a rechargeable battery is a common power
`Source for various portable consumer electronics, such as
`mobile phones, laptops, digital cameras, music players, etc.
`For charging Such a rechargeable battery, a specific charger
`is required to adjust the AC power from the power grid into a
`certain potential. Where the power grid is inaccessible, charg
`ing is impossible and the portable device using the battery
`cannot serve when the battery is exhausted.
`To avoid this plight, a portable power Supply, or a “power
`pack, has been developed. By using the same, users can
`charge their consumer electronics everywhere despite the
`accessibility of the power grid.
`The existing portable power Supply is mainly composed of
`a rechargeable battery and a control circuit that are packed in
`an enclosure. The commercialized products are provided with
`different battery capacities. While a portable power supply
`having a small capacity is usually compact and light, it cannot
`serve long. On the other hand, a portable power Supply having
`a small capacity serves long yet is bulky and less portable. In
`addition, the existing rechargeable battery has its life Subject
`to its age and/or frequency of use and once the battery become
`poor in performance or broken, the whole power Supply is
`unusable.

`
`SUMMARY OF THE INVENTION
`
`In view of the shortcomings of the prior-art device as stated
`above, the present invention provides a portable external
`power-supplying device with a variable power capacity. The
`power-supplying device has detachably combined battery
`units whose number can be adjusted according to user needs,
`which means the overall volume and weight of the power
`Supplying device is manageable. The individual battery units
`are replaceable, so the performance of the power-supplying
`device can be easily maintained. This helps to preserve
`SOUCS.
`To this end, according to the present invention, a portable
`external power-supplying device comprises a power control
`module and one or more battery units whose aggregate capac
`ity is variable. The power control module includes a circuit
`board, an indicator light set, a first port, a powerinlet, a power
`outlet and others. The individual battery unit includes a con
`troller, a cell, a second port and a third port.
`When communicated with the battery units, the control
`module charges the battery units through the power inlet for
`later use. In use, the control module Supplies power to a
`portable electronic device through the power outlet.
`The control module can charge one or more battery units.
`These charged battery units can be easily assembled or sepa
`rated so that one or more battery units can be used to charge
`according to practical needs. As each battery is Subject to its
`cycle life, once any of the individual battery units is out ofuse,
`the power-supplying device can be replenished by replacing
`the broken battery unit with a new one. As compared with

`
`DETAILED DESCRIPTION OF THE INVENTION
`
`Referring to FIG. 1 and FIG. 2, in the present invention, a
`portable external power-supplying device primarily com
`prises a power control module 1 and one or more individual
`battery units 2, 3, 4, 5.
`As shown in FIG. 2, the power control module 1 has an
`enclosure 11 containing therein a circuit board 12. On the
`circuit board 12, there are a charge controller loop 121, a
`buck-boost converter loop 122, a power manager loop 123, a
`button switch 124, an indicator light set 125, a first port 126,
`a power inlet 127 and a power outlet 128. The enclosure 11
`has its back provided with a positioning hole 13 and a fixing
`hole 14.
`The power inlet 127 of the power control module 1 is
`electrically connected to the charge controller loop 121, while
`the charge controller loop 121, the buck-boost converter loop
`122, and the power manager loop 123 are electrically con
`nected together. The power manager loop 123 is electrically
`connected to the button switch 124 and the indicator light set
`125. Meantime, the buck-boost converter loop 122 is electri
`cally connected to the power outlet 128 and the first port 126.
`The button switch 124, the indicator light set 125, the first
`port 126, the power inlet 127, and the power outlet 128 of the
`circuit board 12 are exposed outside the enclosure 11 of the
`power control module 1 to be visible, accessible and operable
`to a user from exterior.
`Therein, the power inlet 127 is adaptive to connect a ter
`minal of an adapter and input a DC power to the power control
`module 1. The power outlet 128 is adaptive to connect a
`battery of a portable electronic device that is to be charged.
`As shown in FIG. 1, the enclosure 21 of each of the indi
`vidual battery units 2, 3, 4, 5 has its top formed with an
`accommodating recess 22. The individual battery unit 2 has

`therein a controller 23, a cell 24, a second port 25 and a third
`port 26. The controller 23 is electrically connected to the cell
`24, the second port 25 and the third port 26. The second port
`25 faces the accommodating recess 22 of the enclosure 21,
`and the third port 26 is located at a side of the enclosure 21.
`The enclosure 21 of the individual battery unit 2 has a posi
`tioning pin 27 and a retaining hook 28 in the accommodating
`recess 22. Each of the individual battery units 2, 3, 4, 5 has its
`back provided with a positioning hole 271 and a fixing hole
`281 corresponding to the positioning pin 27 and the retaining
`hook 28 on another said individual battery unit, respectively.
`As shown in FIG. 3 and FIG. 4, to assemble the compo
`nents, the power control module 1 slides into the accommo
`dating recess 22 of the enclosure 21 of the individual battery
`unit 2, such that the first port 126 of the power control module
`1 gets electrically connected to the second port 25 open to the
`accommodating recess 22 of the individual battery unit 2.
`and, at the same time, the positioning hole 13 and the fixing
`hole 14 of the power control module 1 get engaged with the
`positioning pin 127 and the retaining hook 28 of the indi
`vidual battery unit 2, respectively.
`As shown in FIG. 5 through FIG. 7, after the power control
`module 1 is assembled with the individual battery unit 2, the
`second individual battery unit 3, third individual battery unit
`4, fourth individual battery unit 5 and so on can be succes
`sively combined in the manner described previously to make
`the second port 25 of one battery unit electrically connected to
`and positioned by the third port 26 of another battery unit.
`By doing so, the device of the present invention can have
`the number of the individual battery units 2, 3, 4, 5 increased
`or decreased according to practical needs. Such a slide-in
`operation as shown in FIG. 5through FIG. 7 allows a user to
`use as many battery units as he/she needs. The individual
`battery units 2, 3, 4, 5 thus assembled are convenient to carry
`for the user to charge his/her portable electronic devices any
`where and anytime.
`Referring to FIG. 8 and FIG. 10, the power control module
`1 and each of the individual battery units 2, 3, 4, 5 may
`alternatively have their first port 126 and third port 26 located
`at the backs of their enclosures 11, 21, respectively. In such a
`case, the user can assemble the power control module 1 and
`the individual battery unit 2 and/or the additional battery units
`3, 4, 5 through a stacking operation instead of the foregoing
`slide-in operation where the components are stacked verti
`cally as an integral.
