1. A power storage adapter (PSA), comprising:

  • a PSA port;

    a PSA battery; and

    a PSA controller having access to memory media storing instructions executable by the PSA controller to;

    receive, at a first time, an indication of a peak shift associated with an alternating current (AC) line power source, the indication specifying that the power storage adapter is to cease drawing electrical power from the AC line power source, the indication additionally indicating a further time period when an additional peak shift is to occur;

    determine that a state of charge of the PSA battery is greater than a recharging state of charge;

    in response to the indication and when the power storage adapter is electrically connected to the AC line power source, enter a peak shift by electrically disconnecting the power storage adapter from the AC line power source;

    determine, after electrically disconnecting the power storage adapter from the AC line power source, that the state of charge of the PSA battery is less than the recharging state of charge, and in response, electrically connect the power storage adapter to the AC line power source;

    in response to electrically connecting the power storage adapter to the AC line power source, terminate the peak shift of the AC line power source;

    at a second time after terminating the peak shift of the AC line power source at the first time and during the further time period indicated by the previously received indication, entering the further peak shift of the AC line power source without receiving a further indication of the additional further peak shift associated with the AC line power source, including;

    determine that the state of charge of the PSA battery is greater than the recharging state of charge; and

    when the power storage adapter is electrically connected to the AC line power source, electrically disconnect the power storage adapter from the AC line power source.
