A charger device may include a coupling component configured to deliver power for charging user devices and a wireless interface configured to broadcast wireless signals. The coupling component may include a connector that may be plugged into a user device or an inductive coil to be inductively coupled to a user device. The charger device may determine whether the coupling component is coupled to a user device and transmit via the wireless interface an “available” signal indicating the charger device is available in response to determining the coupling component is not coupled. The user device may provide a notification to the user based, at least in part, on receiving the “available” signal. The user device may provide the notification further based on other information, such as activity of a user detected by the user device, a geolocation determined by the user device, or information received from a service provider. |
