Abstract

Example implementations relate to wireless charging devices. In an example, a wireless charging device includes a housing and circuitry including a power transmitting coil, where the wireless charging device does not include a power amplifier or a power converter.

Claims

1. A wireless charging device, comprising:

a housing having a thickness of 0.2 millimeters to 3 millimeters; and

circuitry including a power transmitting coil disposed within the housing, wherein the power transmitting coil further comprises a resonator coil, a solenoidal wire, or a combination of a resonator coil and a solenoidal wire, and wherein the wireless charging device does not include a power amplifier or a power converter.

2. The wireless charging device of claim 1, wherein the circuitry consists essentially of the power transmitting coil.

3. The wireless charging device of claim 1, wherein the wireless charging device further comprises a wired connector.

4. The wireless charging device of claim 3, wherein the wired connector is a type C universal serial bus (USB) connector to couple to a corresponding type C USB connector in an external device.

5. The wireless charging device of claim 3, wherein the wired connector is retractable within the housing, wherein the wired connector is entirely disposed within an internal volume of the housing when in a retracted position.

6. A wireless charging support device, comprising:

a connector to couple to a wireless charging device;

wireless charging support circuitry including at least a power amplifier or a power converter;

a power supply including an alternative current/direct current power supply; and

a universal dock, wherein the universal dock includes a plurality of wired connectors.

7. The wireless charging support device of claim 6, wherein the plurality of wired connectors further comprises at least two different types of wired connectors.

8. A wireless charging system, comprising:

a wireless charging device including;

a housing having a thickness of 0.2 millimeters to 3 millimeters;

a connector; and

circuitry including a power transmitting coil disposed within the housing; and

a wireless charging support device including;

wireless charging support circuitry; and

a corresponding connector to couple the connector and form the wireless charging system, wherein the wireless charging system is to wirelessly charge an electronic device in proximity of the wireless charging system via the wireless charging support circuitry of the wireless charging support device and the power transmitting coil of the wireless charging device.

9. The wireless charging system of claim 8, wherein the wireless charging support device includes a processor, and wherein the wireless charging device does not include a processor.

10. The wireless charging system of claim 8, wherein the wireless charging support device includes a wireless connection module, and wherein the wireless charging device does not include a wireless connection module.

11. The wireless charging system of claim 8, wherein the wireless connection module includes circuitry to communicate a BLUETOOTH signal, a Wi-Fi signal, a ZIGBEE signal, a FM signal, or combinations thereof.
