The GDS Slide Dock is a scalable solution for charging multiple devices at the same time. This version is compatible with Next Generation IntelliSkin sleeves. Designed to be integrated into a portable charging station, each GDS Slide Dock can be permanently mounted to any surface by being bolted or screwed in. The GDS connector’s height can be easily adjusted to accommodate different devices. The adjustable height settings are numbered to quickly set up for any cart or charging station. This GDS Slide Dock has a USB Type-A male output that can plug into an existing USB port on a cart or into the GDS 6-port USB charger. There is an LED indicator light that turns red when your dock is connected to power. When your device is charging, the LED indicator will glow green.
