Apple eyes ways for wirelessly charging one Apple device from another — Apple World Today

In the patent filings, Apple notes that electronic devices include one or more rechargeable batteries that may require external power to recharge. Often, these devices may be charged using a common or standardized electrical connector or cable. For example, some devices may be charged using a universal serial bus (“USB”) connector or cable. 

However, despite having standardized connectors and cable, each device may require a separate or dedicated power supply to charge. Apple says that, often, having separate power supplies for each device may be burdensome to use, store, and/or transport. The tech giant thinks inductive charging of one Apple device to another is a better idea.
