This is the j5create PC Crosslink Hub, model JCH422. It allows for cross-OS data transfer and display expansion. It can be used with USB-C or USB-A/C connections between an iPad/iPhone and a Windows PC. I purchased it new in 2024 and used it a few times, but it didn't quite fit my needs, so I've been storing it indoors. 【Brand】j5create 【Model Number】JCH422 【Supported OS】iOS/iPadOS/Windows 【Functions】Data transfer from iPad/iPhone to PC, using iPad/iPhone as an external monitor for PC, operating PC with iPad's touch panel, mirroring iPad/iPhone screen to PC 【Ports】Type-Cx1 (Gen1 5Gbps), Type-Ax1 (Gen1 5Gbps)
