Abstract: A charging hub includes a housing and a battery pack. The housing includes a body having a base, and a plurality of satellite device receptacles positioned on the body. The plurality of satellite device receptacles is configured to removably couple a plurality of satellite devices to the body. Each receptacle has an electrical connector configured to charge the plurality of satellite devices. The housing also includes a battery receptacle positioned on the body. The battery pack is removably coupled to the housing at the battery receptacle. The battery pack is operable to provide power to the electrical connectors.

Abstract: A device that includes a controller having a processing unit and a memory. The device includes an enable circuit. The enable circuit prevents the device from operating (e.g., discharging current and/or receiving charging current) until the enable circuit is activated. The enable circuit includes an activation component (e.g., a near-field communication [“NFC”] circuit). The activation component is configured or operable to cause the device to become enabled when the activation component is activated by an external enabling device.
