Power bank and packaging system for a power bank
A power bank system includes a packaging container and a power bank. The packaging container defines an internal cavity and has an external receiving surface. The power bank has a battery, a primary coil, and a sensor. The power bank is positioned within the internal cavity such that the primary coil and the sensor are disposed proximate to an opposing side of the external receiving surface. The external receiving surface is configured to receive a portable device. The power bank is configured to deliver power from the battery to the portable device wirelessly via the primary coil and though the external receiving surface in response to the sensor detecting the portable device being positioned proximate the external receiving surface.
1. A power bank configured to charge portable devices comprising:
a housing having an upper external panel, the upper external panel having first and second upward facing surfaces, wherein the second upward facing surface protrudes upward from and is parallel with the first upward facing surface;
a battery disposed within the housing and configured to store electrical power;
a primary coil disposed within the housing below a first portion of the second upward facing surface, wherein the primary coil is configured to interact with a secondary coil of a portable device to charge a battery of the portable device in response to the portable device being disposed proximate to the second upward facing surface;
a sensor disposed within the housing below a second portion of the second upward facing surface, wherein the sensor is configured to detect a magnetic field generated by the portable device in response to the portable device being disposed proximate to the second upward facing surface; and
a controller programmed to,
in response to the sensor detecting the magnetic field, deliver electrical power from the battery to the primary coil, and
in response to an absence of the sensor detecting magnetic fields, forgo delivering electrical power from the battery to the primary coil.
2. The power bank of claim 1 , wherein the second upward facing surface includes a circular-shaped area and a linear-shaped area that (i) protrudes from the circular-shaped area, (ii) is planar with the circular-shaped area, and (iii) has opposing parallel edges.
3. The power bank of claim 2 , wherein the primary coil is disposed below the circular-shaped area.
4. The power bank of claim 2 , wherein the sensor is disposed below the linear-shaped area.
5. The power bank of claim 1 , wherein the sensor is a hall-effect sensor.
6. The power bank of claim 1 , wherein the sensor is powered via the battery.
7. The power bank of claim 1 , wherein the sensor is powered via a secondary battery and is isolated from the battery.
8. The power bank of claim 1 , wherein the primary coil is disposed within the housing at least partially above the first upward facing surface.
9. A power bank configured to charge portable devices comprising:
a housing having an upper external panel, the upper external panel having first and second upward facing surfaces, wherein the second upward facing surface protrudes upward from and is parallel with the first upward facing surface;
a battery disposed within the housing and configured to store electrical power;
a primary coil disposed within the housing and below the second upward facing surface, wherein the primary coil is configured to interact with a secondary coil of a portable device to charge a battery of the portable device in response to the portable device being disposed and detected proximate to the second upward facing surface; and
a sensor disposed within the housing, wherein the sensor is configured to detect a magnetic field generated by the portable device in response to the portable device being disposed proximate to the second upward facing surface.
10. The power bank of claim 9 further comprising an array of magnets disposed within the housing and radially about an outer periphery of the primary coil.
11. The power bank of claim 10 , wherein a gap is defined between first and second magnets of the array of magnets and adjacent magnets of the remainder of the array of magnets abut each other such that no gaps are defined therebetween.
12. The power bank of claim 11 , wherein the sensor is disposed within the gap.
13. The power bank of claim 10 , wherein the array of magnets is disposed below an inclined surface that connects the first upward facing surface to the second upward facing surface.
14. The power bank of claim 13 , wherein the sensor is disposed below the inclined surface.
15. The power bank of claim 9 further comprising a controller programmed to, (i) in response to the sensor detecting the magnetic field, deliver electrical power from the battery to the primary coil, and (ii) in response to an absence of the sensor detecting magnetic fields, forgo delivering electrical power from the battery to the primary coil.
16. The power bank of claim 1 , further comprising an array of magnets disposed within the housing and radially about an outer periphery of the primary coil.
17. The power bank of claim 16 , wherein the array of magnets is disposed below an inclined surface that connects the first upward facing surface to the second upward facing surface.
18. The power bank of claim 9 , wherein the primary coil is disposed within the housing at least partially above the first upward facing surface.
19. The power bank of claim 9 , wherein the second upward facing surface includes a circular-shaped area and a linear-shaped area that (i) protrudes from the circular-shaped area, (ii) is planar with the circular-shaped area, and (iii) has opposing parallel edges.
20. The power bank of claim 19 , wherein (i) the primary coil is disposed below the circular-shaped area and (ii) the sensor is disposed below the linear-shaped area.
