Abstract

A portable electrical charging device has a rechargeable battery, an electrical charge outlet by which said rechargeable battery provides an electrical charge, and a control circuit. The control circuit has a timer function. The control circuit permits an electrical charge to be drawn from the electrical charge outlet for a pre-determined period of time only, by reference to the timer function.

Claims

1. A portable electrical charging device comprising a rechargeable battery, an electrical charge outlet by which said rechargeable battery provides an electrical charge, and a control circuit, in which said control circuit comprises a timer function, and in which said control circuit permits an electrical charge to be drawn from said electrical charge outlet for a pre-determined period of time only, by reference to said timer function.

2. The portable electrical charging device as claimed in claim 1 further comprising an electrical charge inlet by which said rechargeable battery can draw an electrical charge for storage, in which said control circuit comprises a first monitoring function which detects the drawing of an electrical charge by said rechargeable battery, and in which said control circuit is configured to only permit an electrical charge to be drawn from said electrical charge outlet for said pre-determined period of time, after it has detected the drawing of an electrical charge by said rechargeable battery.

3. The portable electrical charging device as claimed in claim 1 in which said control circuit comprises a second monitoring function which detects the drawing of an electrical charge from said electrical charge outlet, in which once said control circuit detects the drawing of an electrical charge from said electrical charge outlet it activates said timer function, and in which said control circuit is configured to prevent electrical charge being drawn from said electrical charge outlet after said pre-determined period of time has elapsed regardless of whether an electrical charge is drawn from said electrical charge outlet after said timer function has been activated.

4. The portable electrical charging device as claimed in claim 2 further comprising a visual display, in which said visual display displays at least a first signal after the control circuit has detected the drawing of an electrical charge by said rechargeable battery.

5. The portable electrical charging device as claimed in claim 4 in which said visual display displays a second signal after an electrical charge has been drawn from said electrical charge outlet, but prior to the end of said pre-determined period of time.

6. The portable electrical charging device as claimed in claim 5 in which said visual display displays a third signal after an electrical charge has been drawn from said electrical charge outlet for said pre-determined period of time.

7. The portable electrical charging device as claimed in claim 6 in which said second signal is a flashing LED.

8. The portable electrical charging device as claimed in claim 5 in which said second signal is a visual clock displaying the time remaining of said pre-determined period of time.

9. The portable electrical charging device as claimed in claim 2 in which said charging device comprises an outer enclosure, in which said electrical charge inlet comprises a contact-point wireless charging mechanism comprising a first magnetic conductor and a second magnetic conductor, in which an inner end of said first magnetic conductor is connected to a positive terminal of the rechargeable battery and an outer end of said first magnetic conductor is disposed in a first aperture provided in said outer enclosure, in which an inner end of said second magnetic conductor is connected to a negative terminal of the rechargeable battery and an outer end of said second magnetic conductor is disposed in a second aperture provided in said outer enclosure, in which said first aperture and said second aperture are disposed in the same plane, and are spaced apart from one another in said plane, in which said portable electrical charging device further comprises a contact-point wireless electromagnetic charging plate comprising a positive panel and a negative panel, and in which said portable electrical charging device is disposable on said charging plate with said first aperture aligned with said positive panel and said second aperture aligned with said negative panel.

10. The portable electrical charging device as claimed in claim 1 in which said electrical charge outlet comprises at least two electrical charging plugs each capable of being connected to an electrical device to be charged.

11. The portable electrical charging device as claimed in claim 10 in which said at least two electrical charging plugs are a different shape and configuration from one another.
