Classification: CPC H  G | IPC G  H

Claim 9:
10. A charging cable, comprising:
power and ground buses;
a cable head having power and ground pins coupled respectively to the power and ground buses and configured to engage contact pads of a receiver of a chargeable device having a battery, when the cable head is coupled to the receiver of the chargeable device;
a current sensor coupled to at least one of the power and ground buses to detect current flow via the pins;
a state indicator for providing an output perceptible to a user; and
logic circuitry coupled to operate the state indicator, the logic circuitry configured to compare level of current detected by the current sensor to a threshold and, in response to results of the comparison, control the state indicator to provide a perceptible output and maintain the perceptible output while the current sensor periodically detects peaks of modulated current pulses at or above the threshold.
