Designs for a magnetic mounting system that facilitate wireless charging. The magnetic mounting system generally includes an attachment member engaged with a device that interfaces magnetically with a carrier member. The attachment member may comprise a split ring or discontinuous ring comprising arcuate members that allows inductive coupling between a charge transmitting coil and a charge receiving coil to be achieved as the arcuate members do not interfere with the inductive coupling. Specifically, rather than a solid plate in which the RF energy emitted by the charge transmitting coil generates eddy currents in the plate, the arcuate members are substantially transparent to the RF energy such that inductive coupling may be achieved.

An aerosol generating system includes a holder including: a heater configured to heat an aerosol generating article; a holder battery configured to supply electric power to the heater; and a holder processor configured to measure a remaining charge value of the holder battery; and a cradle detachably coupled to the holder and including: a cradle battery having a greater battery capacity than the holder battery; and a cradle processor configured to: identify whether the holder is coupled to the cradle, receive a remaining charge value of the holder battery from the holder processor based on the holder being coupled to the cradle, and control the cradle battery to supply electric power to the heater based on the received remaining charge value being greater than or equal to a preset reference value.

A method charges an energy storage unit of a mobile device, in particular a hearing aid, which is alternately able to be charged in charging phases and able to be used in use phases. For the charging in an upcoming charging phase, a probable duration of the upcoming charging phase and a probable energy consumption of a subsequent use phase are determined based on past charging phases and past use phases. A required charge for the energy storage unit is calculated based on the probable energy consumption. A charging schema for charging the energy storage unit is set for the upcoming charging phase based on the required charge and the probable duration. A mobile device and a charging device are also specified.

Eyewear that is configured to be wirelessly charged and also wirelessly communicate with a case charger having a battery using time gating power transfer. In one example, wireless charging and bidirectional communication of the eyewear can be performed using a unidirectional communication protocol, such as the Qi baseline power profile (BPP) which is only suited for unidirectional communication. The eyewear has a processor configured to send data to the wireless power charger that instructs the wireless power charger to stop wireless charging for a time period that is correlated to a state of charge (SOC) of the wireless power charger battery. The wireless power charger resumes charging of the eyewear battery after the time period, and the eyewear determines the SOC of the wireless power charger battery to be a percentage that correlates to the time period.

A wearable earphone charger with automatic adjustment of positive and negative polarities includes a wearable bracket and two power supply seats disposed on the bracket. The bracket is provided with a power supply integrated control board and a power supply electrically connected to each other. Each of the two power supply seats is electrically connected to the power supply integrated control board, is provided with first and second power supply contacts that are used to supply power to an earphone, and is further provided with a detection contact. The power supply integrated control board is provided with a detection circuit used to detect whether the earphone is connected, and the detection circuit is electrically connected to the detection contact. The wearable earphone charger can realize automatic adjustment of positive and negative polarities of the wearable earphone charger, and thus is with high reliability and improved user experience.

A charging management system is provided based on communications between a charging device and a reporting device. The charging device may interface with the reporting device via a multi-contact surface, a conventional plug, or otherwise, the reporting device may typically comprise a portable, rechargeable device such as a smartphone, smart watch, camera, etc. Communications between the between the charging device and the reporting device take place via the same pair of power lines as are used for providing power from the charging device and the reporting device, by means of a non-volatile memory in the reporting device, which is accessed sequentially by one device or the other, and used to store information to be retrieved by the other to retrieve when activated. This exchange of information may implement a negotiation of a mutually acceptable power supply configuration, an authentication of a particular reporting device, etc.

A power adapter provides power to an information handling system. The power adapter includes a power supply and a power delivery controller. The power supply receives an alternating current (AC) input at one of a plurality of input voltages, and provides a direct current (DC) output at one of a plurality of output voltages, each output voltage being associated with a current limit. The power delivery controller determines, upon being plugged into an AC power source, a first input voltage of the AC power source, determines a DC power delivery capability of the information handling system, sets a first output voltage and a first current limit of the power supply DC output based upon the first input voltage and the DC power delivery capability, the first output voltage and the first current limit defining a first power limit to the information handling system, determines that the power supply can provide a second power limit that is greater than the first power limit based upon an operating condition of the power supply, and communicates the second power limit to the information handling system.

A portable wireless charging system may include a charging case and at least one power bank received in the case. The charging unit can be charged when it is received in the case through an external charging cable. In one embodiment, the power bank can be taken out to attached to a back portion of a mobile device to charge the device. In another embodiment, the mobile device can be charged when being disposed on a front or back surface of the charging case when the charging unit is inside the case.

A charge method for a battery, a storage medium, and a terminal are provided and include: acquiring a discharge current of the battery when the battery is in a charge state; determining whether the discharge current is smaller than a predetermined current threshold value; if yes, determining whether the discharge current is in a stable state within a predetermined time period; and selecting a target voltage from a plurality of sample voltages in a predetermined voltage set according to a result of the stable state, adopting the target voltage as a charge voltage to charge the battery, and continuing to perform the determining whether the discharge current is smaller than the predetermined current threshold value.

A headset charging dock includes a headset mechanical support configured to hang a first headset by a headband of the first headset; and a wireless charging interface for the first headset, the wireless charging interface integrated in the headset mechanical support.
