Abstract: A reminder system for a portable-device charger is designed for determining when it is likely that the charger is about to be left behind. Detection which may be in real time can pertain, depending on the embodiment, to disconnection of a portable device from the charger, and/or movement of a portable device out of wireless range of the charger or a charger adaptor. In some versions, the onset of reminding is, upon detecting disconnection, tentatively postponed until a predetermined criterion is met, such as expiry of a predetermined time period. Or the criterion can be detection of an out-of-range condition based on distance between the portable device and an adaptor or charger. In some embodiments detection and reminder issuance are incorporated in a unit, such as a plug-in wall adaptor or the charger itself.
