1. A control unit comprising:
a processor; and
non-transitory computer-readable media configured to store computer-executable instructions configured to cause the processor to:
determine a reserve level for a battery of a first device, the reserve level configured to provide electrical power to the device to perform one or more functions;
determine information chosen from usage information for the first device and weather information;
determine the reserve level responsive to the information;
filter the received usage information to include at least one location which the first device has visited more than a threshold amount;
determine the reserve level further responsive to the filtered usage information;
enable the battery to supply power to a second device external to the first device responsive to a power level of the battery reaching the reserve level; and
disable the battery from supplying the power to the second device responsive to the power level of the battery falling below the reserve level.
