Abstract
Aspects of the disclosure relate to a wireless charging device having an inductive charging coil built into a keyboard, such as the interior space of a keycap in the keyboard. The wireless charging device and keyboard may further be built into a housing of a primary device, such as a laptop computer. The wireless charging device may communicate with another secondary device having a compatible coil. For example, the wireless charging device may transmit, via the inductive charging coil, a wireless charging signal to a wirelessly chargeable device placed on top of the keyboard. In another example, the wireless charging device may receive, through the inductive charging coil, a wireless charging signal from a wireless powering device placed on top of the keyboard.
