Powered USB charger fits into a 1-3/4" hole and plugs in underneath. Sleek minimalist style integrates seamlessly into your design nearly flush with the surface. Locking ring underneath allows it to mount just about anywhere. Vertically or horizontally, on a desktop or in the arm of a chair or any type of furniture. Dual charger includes inputs rated 2A each, suitable for iPads and tablets or any other USB powered mobile device. Perfect retrofit option to upgrade an existing grommet hole and fit to size or add virtually anywhere for convenient charging options. Note, this device is for charging only and does not allow data transfer.
