AI summary

Using inductive currents to wirelessly charge a device via a device connected to a power source. This inductive charging may result when a first mobile device recognizes a second mobile device via a wireless connection (e.g., Bluetooth, Bluetooth Low Energy (BLE), Near-Field Communication (NFC), or the like). An application stored on the first mobile device may recognize a second mobile device by transmitting an advertising packet when the first mobile device is connected to a power source. An advertising packet may be received by the second mobile device and the second mobile device may transmit a response to the advertising packet in order to generate a connection between the first and second mobile devices. The response may include data such as, connection strength, response time, connection preferences, and the like. Upon detection and connection, the second mobile device may be wirelessly charged by the first device via inductive charging.
