Qi

Add the convenience of wire-free charging to furniture in your lobby, conference rooms and guest rooms! You only have to place a Qi-compatible device (cellphone, tablet) on a recessed inductive surface and charging begins. Position phone on the center of the grommet until the blue indicator light ring activates to signify that the device is recognized and is actively charging. If there is a problem, the ring will flash red. Make sure to use supplied AC adapter. More
