Definitions
- the present invention relates to a power charging system, and more particularly, to a power charging system for portable electric devices.
- a charging system including a transformer and power cord designed for each portable electric device allows usage of these portable electric devices anytime and anywhere.
- FIG. 1 is a schematic diagram illustrating a portable electric device 10 A charging system according to prior art.
- the portable electric device 10 A has a charging port 12 A for inputting a DC (direct current) working voltage.
- Two corresponding transformers 16 A and 18 A are used to charge the portable electric device 10 A.
- An AC (alternating current) power 20 is input via an input port 17 A of the transformer 16 A, altered by the transformer 16 A to the working voltage of the portable electric device 10 A, and output via an output port 14 A of the transformer 16 A.
- a DC power 22 is input via an input port 19 A of the transformer 18 A, altered to the working voltage of the portable electric device 10 A, and output via an output port 15 A of the transformer 18 A.
- Users can select the transformer 16 A or 18 A to charge the portable electric device 10 A by connecting the input port of the transformer to a corresponding power source and connecting the output port of the transformer to the charging port 12 A of the portable electric device 10 A.
- an input power is first transformed into the specially designed working voltage of a portable device by a corresponding transformer, delivered from the output port of the transformer to the corresponding charging port of the portable electric device, and is finally used to charge the portable electric device.
- a portable electric device 10 B shown in FIG. 1 , also has a specially designed charging port 12 B for inputting its specially designed working voltage.
- the transformers 16 B and 18 B respectively have corresponding output ports 14 B and 15 B.
- An AC power 20 is input via an input port 17 B of the transformer 16 B, altered by the transformer 16 B into the specially designed working voltage of the portable electric device 10 B, and output to the charging port 12 B via the output port 14 B of the transformer 17 B.
- a DC power 22 is input via an input port 19 B of the transformer 18 B, altered to the specially designed working voltage of the portable electric device 10 B, and output to the charging port 12 B via the output port 15 B of the transformer 18 B.
- Different portable electric devices have different specially designed working voltages.
- the working voltage of modern portable electric devices varies from 3 volts to 12 volts.
- the charging port of each portable electric device also has a different shape and structure.
- a prior art portable electric device is equipped with its own specially designed transformer. These special transformers convert an input power via their input ports into the specially designed working voltage of the corresponding portable electric device. The output ports of these transformers must match the specially designed charging port of the portable electric device.
- users carry two (or even more) portable electric devices, they have to carry corresponding specially designed transformers to charge their portable electric devices.
- the transformers 16 A and 16 B both can transform the AC power 20 to DC power
- the transformed voltages that are output from each transformer are still the two specially designed and often different working voltages of the portable electric devices 10 A and 10 B.
- the output ports 14 A and 14 B of the transformers 16 A and 16 B also have different shapes. These two reasons make the specially designed transformer 16 A of the portable electric device 10 A incompatible with the portable electric device 10 B.
- the specially designed transformer 16 B of the portable electric device 10 B cannot charge the portable electric device 10 A.
- users plan to charge a portable electric device with two different kinds of power sources, they have to carry at least two different specially designed transformers for each portable electric device to transform different power sources into the specially designed working voltage of the portable electric device. As shown in FIG. 1 , users have to carry the two specially designed transformers 16 A and 18 A with them to charge the portable electric device 10 A from two different power sources, the DC power 22 and the AC power 20 .
- a disadvantage of prior art is that users have to carry each specially designed transformer for each portable electric device to charge the portable electric device. It is obviously quite inconvenient for users to carry every possible charging combination for every portable electric device that they carry. Moreover, the weight and the volume of the transformers 16 A or 16 B, used in transforming AC power to DC power, is hard to further reduce. Additionally, it is also difficult to store power cords (power cords 21 A and 23 A of the transformers 16 A and 18 A) because of their lengths. Any portable electric device needs to be equipped with every kind of specially designed transformer to charge from different power sources, increasing the cost of portable electric devices and restricting the development of the information industry.
- the charging system for charging a plurality of portable devices includes a corresponding charging port for inputting a working voltage, each of the portable devices having a different working voltage.
- the charging system includes a plurality of transformers for converting a plurality of different input voltages into a standard DC (direct current) voltage. Each of the transformers has an output port for outputting the standard DC voltage.
- the charging system includes a power cord that includes a first connection end removably connected to the output port of the transformer for inputting the standard DC voltage and a second connection end for outputting the standard DC voltage.
- the charging system also includes a plurality of conveners lo change the standard DC voltage into the corresponding working voltages of the plurality of portable devices.
- Each of the converters includes an input port removably connected lo the second connection end of the power cord for receiving the standard DC voltage and an output port removably connected to the charging port of a portable device for outputting the working voltage of the portable device.
- users can connect the power cord to the corresponding converter and to any one of the transformers, using the standard DC voltage to charge the plurality of the portable devices.
