Abstract

Wireless chargers are provided. The wireless chargers can simultaneously receive and transmit power wirelessly. The wireless chargers can include a rechargeable battery so that the wireless charges can be used portably to charge electronic devices. The wireless chargers can also be programmable so that a user can select a power-transmitting protocol that is particularly suited for the electronic device being charged.

Claims

1. A wireless charger, comprising:

a housing;

a wireless power-transmitting device located in the housing; and

control logic located in the housing, the control logic being capable of transferring power received by the wireless power-receiving device to the wireless power-transmitting device.

2. The wireless charger of claim 1, comprising:

a rechargeable battery located in the housing, wherein the control logic is capable of transferring power received by the wireless power-receiving device to the rechargeable battery, and wherein the control logic is capable of transferring power from the rechargeable battery to the wireless power-transmitting device.

3. The wireless charger of claim 1, wherein the control logic is capable of operating the wireless power-transmitting device to wirelessly transmit power in accordance with a selectable power-transmitting protocol.

4. The wireless charger of claim 3, comprising:

a wireless communications device capable of wirelessly receiving an identification of a selectable power-transmitting protocol.

5. The wireless charger of claim 3, comprising:

a plurality of selectable buttons, each of the plurality of buttons having a power-transmitting protocol associated with it, wherein the control logic is capable of detecting when one of the selectable buttons is selected, and wherein the control logic is capable of operating the wireless power-transmitting device in accordance with the power-transmitting protocol associated with the selected button.

6. The wireless charger of claim 5, comprising:

a wireless communications device capable of receiving identifications of power-transmitting protocols, wherein the control logic is capable of associating each of the plurality of selectable buttons with a power-transmitting protocol corresponding to a received identification.

7. A charging system, comprising:

a first wireless charger capable of wirelessly transmitting power; and

a second wireless charger, the second wireless charger comprising;

a housing;

a wireless power-receiving device located in the housing, the wireless power-receiving device capable of wirelessly receiving power transmitted from the first wireless charger;

a wireless power-transmitting device located in the housing; and

control logic located in the housing, the control logic being capable of transferring power received by the wireless power-receiving device to the wireless power-transmitting device.

8. The charging system of claim 7, wherein the second wireless charger comprises:

a rechargeable battery located in the housing, wherein the control logic is capable of transferring power received by the wireless power-receiving device to the rechargeable battery, and wherein the control logic is capable of transferring power from the rechargeable battery to the wireless power-transmitting device.

9. The wireless charger of claim 8, wherein the first wireless charger includes a first wireless communications device, wherein the second wireless charger includes a second wireless communications device, and wherein the second wireless charger is capable of transmitting, via the second communications device, a message to the first wireless charger, via the first communications device, to stop the first wireless charger from wirelessly transmitting power.

10. The charging system of claim 7, wherein the control logic is capable of operating the wireless power-transmitting device to wirelessly transmit power in accordance with a selectable power-transmitting protocol.

11. The wireless charger of claim 10, wherein the second wireless charger comprises:
