Computer maker Dell has patented the design of a detachable clip for laptop computers that provides wireless charging.
The clip uses a printed graphene charging coil built with a ferrite sheet as well as magnetic elements to hold the clip in place. This avoids increasing the size and thickness of the laptop, say the developers.
When the clip is installed on the laptop, charging circuitry is configured to supply inductive power to charge an auxiliary device such as a smartphone.

The charging coil may include multiple graphene layers and the clip may include a second surface and a third surface including the connector through which input power is received from the information handling system.
