Automatic Hold Wireless Charging Holder Thank you for viewing. This is a smartphone holder that plugs into a cigarette lighter. Near the cigarette lighter socket, there are two USB ports. When you place your smartphone on it, it automatically opens and closes, and charges automatically. I am selling this because the cup holder was difficult to use (the cigarette lighter is directly below the cup holder). I have hardly used it, but it is a used item, so please understand this before purchasing.
