This USB 2.0 Type-C cable is perfect for use with your Raspberry Pi 4 and other USB Type C boards. USB Type-C Connectors and Cable Assemblies offer greater PCB savings while enabling high-frequency mating in data, consumer, and other I/O applications.
This cable uses the Type-C form-factor but only connects pins for USB 2.0 specification. It supports a maximum signaling rate of 480 Mbit/s (60 MB/s) and a max current of 1.5A (with data transfer) and up to 5A if used for power/charging only.

Handles the current load for charging a recent iPad quite well and connectors and cable don't show noticeable warming. I don't have any benchmark data on data transfer, but it works fine.
