The Sonos Charging Cradle 100 is the ultimate charging and resting place for your Sonos Controller. When the Controller is in the Cradle, it remains fully functional…not to mention easy to find. Use the AC Adapter that comes with every Controller for power. Mount it on the wall (custom-fit bracket, anchors and screws are included) or place it on a table. Either way, when the Controller is resting in its cool new home, it works like a charm.
