There are four items in the box: PowerExpand 12-in-1 USB-C PD Media Dock, a 60W wall charger, a USB 2.0 cable (6 ft), and a USB 3.1 cable (3 ft).

“A” refers to the wall charger.

“B” refers to the 3 ft USB 3.1 cable.

To connect the dock to a laptop with a USB-C port that can support Power Delivery and DisplayPort Alt Mode, please follow the steps:

1. Use the USB 3.1 cable (3 ft) to connect the dock to the laptop by plugging one end of the cable into either USB-C PD port of the dock and the other end into the USB-C port of your laptop.

2. Use the USB 2.0 cable (6 ft) to connect the dock and the charger by plugging one end of the cable into the other USB-C PD port of the dock and the other end to the charger.

If you still have problems with how to connect the dock to your laptop to get it working, please contact us for further assistance.
