CHARGER, CHARGE INDICATOR, AND ASSOCIATED METHODS
A system and method for charging battery packs is provided. The system may include a charging pad comprising a power supply, a charging pad surface, and a microcontroller unit. The power supply may provide charging power. The charging pad surface may include a first charging region and a second charging region. The microcontroller unit may control delivery of charging power to the first charging region and the second charging region such that a device placed in contact with the first charging region is given a higher charging priority than a device placed in contact with the second charging region.

21 . A charging system, comprising:
a charging surface comprising a first region and a second region, wherein:
the first region and the second region are non-overlapping, and
the first region recharges a device faster than the second region.
22 . The charging system of claim 21 , wherein the charging system comprises a controller configured to monitor charging.
23 . The charging system of claim 21 , wherein the charging system comprises a controller configured to:
monitor a first charge level of a first device when placed in contact with the first region of the charging surface, and
monitor a second charge level of a second device when placed in contact with the second region of the charging surface.
24 . The charging system of claim 21 , wherein the charging system comprises a controller configured to:
direct an available charging power solely to the first region of the charging surface in response to the device being placed in contact with the first region and no device being placed in contact with the second region of the charging surface.
25 . The charging system of claim 21 , comprising:
a power supply; and
a power cord configured to couple the power supply to a power outlet;
wherein the power supply provides an available charging power according to power received via the power cord when coupled to the power outlet.
26 . The charging system of claim 21 , comprising one or more battery cells configured to provide an available charging power.
27 . The charging system of claim 26 , comprising one or more solar panels configured to recharge the one or more battery cells.
28 . The charging system of claim 21 , comprising:
first metal strips arranged along the first region of the charging surface such that contact points of the device contact the first metal strips when the device is placed in contact with the first region of the charging surface; and
second metal strips arranged along the second region of the charging surface such that the contact points of the device contact the second metal strips when the device is placed in contact with the second region of the charging surface.
29 . A charging system, comprising:
a charging surface comprising a first region and a second region that is distinct from the first region; and
a controller configured to:
monitor a first charge level of a first device when placed in contact with the first region;
monitor a second charge level of a second device when placed in contact with the second region; and
direct a first charging power to the first region and a second charging power to the second region that is less than the first charging power in response to a determination that a first partially charged level indicated by the first charge level of the first device is lower than a second partially charged level indicated by the second charge level of the second device.
30 . The charging system of claim 29 , wherein the controller is configured to direct charging power solely to the first region in response to no device being placed in contact with the second region.
31 . The charging system of claim 29 , wherein the controller is configured to direct charging power solely to the first region in response to the second device being fully charged.
32 . The charging system of claim 29 , wherein the controller is configured to determine a charge level according to a voltage.
33 . The charging system of claim 29 , wherein the controller is configured to determine a charge level according to a discharged amount.
34 . The charging system of claim 29 , wherein:
the first region comprises metal strips configured to contact the first device; and
the second region comprises metal strips configured to contact the second device.
35 . The charging system of claim 29 , comprising:
a power supply; and
a power cord configured to couple the power supply to a power outlet.
36 . The charging system of claim 29 , comprising one or more battery cells configured to provide charging power.
37 . A method of charging, the method comprising:
monitoring, via a controller, a first charge level of a first device placed in contact with a first region of a charging surface;
monitoring, via the controller, a second charge level of a second device placed in contact with a second region of the charging surface; and
increasing an effective charge rate of the first region in response to the controller determining that a first partially charged level indicated by the first charge level is lower than a second partially charged level indicated by the second charge level.
38 . The method of claim 37 , comprising directing charging power solely to the first region of the charging surface in response to the controller:
determining that the first device is placed in contact with the first region of the charging surface; and
determining that no device is placed in contact with the second region of the charging surface.
39 . The method of claim 37 , comprising directing charging power solely to the first region of the charging surface in response to the controller:
determining that the first device is placed in contact with the first region of the charging surface; and
determining that the second device placed in contact with the second region of the charging surface is fully charged.
40 . The method of claim 37 , comprising conductively charging the first device via first contact points of the first device that are in contact with the first region of the charging surface.
