Anker PowerExpand 9-in-1 USB-C PD Dock Docking Station For a PC refresh, I am selling this. This is a convenient item that connects to a laptop with a single USB-C cable, allowing you to connect power, monitors, LAN, USB peripherals, etc. I used it at home as a stationary device. The power adapter is larger than the main unit, so it is not suitable for carrying around. I recommend using it as a stationary device at home or in the office. I used it with three Windows PCs. Although the USB 2.0 port was not recognized on some PCs, I believe this was due to driver or compatibility issues. I have never had any issues with display output, USB-C ports, LAN, or USB 3.0 ports, so I don't think you need to worry. ＜Product Specifications＞ Body size: Approximately 14.5 × 6.5 × 2.4 cm Body weight: Approximately 188g Adapter size: Approximately 15.3 × 6.1 × 3.6 cm Included cable: USB-C & USB-C 3.1 Gen 2 cable (approx. 0.9m) ＜Port Details＞ ＜Front＞ Kensington security slot 3.5mm audio jack USB-A 3.0 port (5Gbps, 5V=1.5A) USB-C port PD compatible (5Gbps, USB PD 20W) *Does not support video output Uplink USB-C port PD compatible (5Gbps, 60W) *Port for connecting this product to a laptop ＜Rear＞ DC input port (100W / 20.0V = 5.0A) HDMI port (up to 4K (60Hz)) DisplayPort (up to 4K (60Hz)) USB-A 2.0 port (480Mbps, 5V=0.5A) Ethernet port (10/100/1000Mbps) ・Please make sure that the devices you are using support USB Power Delivery and DisplayPort Alternate Mode. ・Your laptop must support DisplayPort 1.4 to support single 4K (60Hz) or dual 4K (30Hz) displays. ・macOS only supports SST and does not support MST.
