Abstract

The present invention discloses devices, for adaptive fast-charging of mobile devices, including: a charge-delivering device for providing electrical power to a charge-receiving device; and at least one electrical-contact pin for enabling electrical current to be transmitted at an amperage greater than about 5 A to the charge-receiving device. Preferably, the charge-receiving device is selected from the group consisting of: an integral power-source component of a mobile device and a slave battery. Preferably, at least one electrical-contact pin is further configured to transmit the electrical current at an amperage selected from the group consisting of: greater than about 10 A, greater than about 20 A, greater than about 30 A, and greater than about 60 A. Preferably, at least one electrical-contact pin is spring-loaded. Preferably, at least one electrical-contact pin includes protection circuitry for protecting against thermal overloads and short circuits. Preferably, the device charger further includes: a receiving-area holder for properly engaging the charge-receiving device.

Claims

1. A device charger for adaptive fast-charging of mobile devices, the device charger comprising:

(a) a charge-delivering device for providing electrical power between 60 and 100 watts to a charge-receiving device, wherein the charge-delivering device is an AC device charger, a DC device charger, an AC/DC charger, or a secondary slave battery and wherein said charge-receiving device is a primary slave battery;

(b) at least one electrical-contact pin coupled to the charge-receiving device for enabling electrical current to be received at an amperage greater than about 5 A by said charge-receiving device; and

(c) at least one electrical-contact pad coupled to the charge-delivering device for enabling electrical current to be transmitted at an amperage greater than about 5 A from the charge-delivering device.

2. The device charger of claim 1, wherein said charge-receiving device is selected from the group consisting of:

an integral power-source component of a mobile device and a slave battery.

3. The device charger of claim 1, wherein said at least one electrical-contact pin is further configured to transmit said electrical current at an amperage selected from the group consisting of:

greater than about 10 A, greater than about 20 A, greater than about 30 A, and greater than about 60 A.

4. The device charger of claim 1, wherein said at least one electrical-contact pin is spring-loaded.

5. The device charger of claim 1, wherein said at least one electrical-contact pin includes protection circuitry for protecting against thermal overloads and short circuits.

6. The device charger of claim 1, the device charger further comprising:

(d) a receiving-area holder for properly engaging said charge-receiving device.

7. The device charger of claim 1, wherein said at least one electrical-contact pad is spring-loaded.

8. The device charger of claim 1, wherein said at least one electrical-contact pad is recessed in an engagement face of said primary slave battery.

9. The device charger of claim 1, wherein said at least one electrical-contact pad is further configured to transmit said electrical current at an amperage selected from the group consisting of:

greater than about 10 A, greater than about 20 A, greater than about 30 A, and greater than about 60 A.

10. The device charger of claim 1, wherein said at least one electrical-contact pad includes protection circuitry for protecting against thermal overloads and short circuits.
