Used a few times. No outer box. Manual included, but only in English and Chinese. Unusually for a docking station, the connection cable is detachable. The HDMI likely has an initial defect and doesn't connect. Based on my own testing, it's not compatible with the Galaxy S25, and the headphone jack also didn't work. I was able to confirm the headphone jack's normal operation with other devices. The dimensions are approximately 10cm wide, 5cm deep, and 2cm high. * USB-C for PC/Smartphone connection * PD USB-C (100W) * USB-C (10Gbps) x 1 * USB-A (10Gbps) x 2 * RJ45-2.5G LAN x 1 * 3.5mm Headphone Jack x 1 * HDMI 2.0 x 1 (operation not confirmed) USB Hub
