Abstract

Embodiments of the present invention may provide a portable energy harvesting, energy storage and battery charging device. The portable device consistent with embodiments of the invention may be worn as, for example, a wrist application. The portable device may incorporate any one of, or a combination of, thermoelectric and solar energy harvesting technology as a source for charging, for example, at least one rechargeable battery. The energy may be stored for later use to, for example, recharge portable electronic devices on the go. In various embodiments, the portable device may be configured to provide a time, date and energy supply in a convenient display. Furthermore, the portable device may incorporate, into its design, integrated Universal Serial Bus (USB) connectors for convenient and direct charging of other portable electronic devices. The USB connector may also be configured to cause a charging of the battery of the portable device.

Claims

1. An apparatus comprising:

a housing comprising an exterior portion and an interior portion;

a solar cell integrated within the exterior portion of the housing;

a battery, within the interior portion of the housing, coupled to the solar cell;

a connector coupled to the battery; and

at least one strap coupled to the housing.

2. The apparatus of claim 1, wherein the battery is configured to store energy harvested by the solar cell.

3. The apparatus of claim 1, wherein the connector is coupled to the battery so as to enable the battery to supply energy to the connector.

4. The apparatus of claim 1, wherein the connector is coupled to the battery so as to enable the battery to receive energy from the connector.

5. The apparatus of claim 1, further comprising:

a push button; and

a display.

6. The apparatus of claim 5, wherein the push button is configured to cause, upon depression, an indication to appear on the display.

7. The apparatus of claim 6, wherein the display is configured to indicate an energy level of the battery.

8. The apparatus of claim 1, wherein the connector is configured to receive an energy from an external energy supply.

9. The apparatus of claim 1, wherein the connector is configured to supply energy stored in the battery to an external electronic device.

10. The apparatus of claim 1, wherein the connector is configured to be connected to a charging cord.

11. The apparatus of claim 10, wherein the charging cord comprises a universal serial bus (USB) connector at one end.

12. The apparatus of claim 10, wherein the charging cord comprises a 2.5 mm jack at one end.

13. The apparatus of claim 10, further comprising a casing for the charging cord.

14. The apparatus of claim 1, wherein the connector is in the form of a crown of a watch.
