The MFI certified SC15, SC19, and SC21 cables have been designed to be used for data transfer compatibility with the RØDECaster Pro II, RØDECaster Duo, and Streamer X. It's important to note that direct charging of iPhones using these cables is not supported.
However, to charge your iPhone while utilizing the RØDECaster Pro II, a viable solution involves employing the official Apple Camera adapter. This adapter establishes a connection between your iPhone and the RØDECaster Pro II. You can then extend a lightning power cable from the Apple Camera adapter to your iPhone, ensuring both efficient charging and the simultaneous transmission of audio into the RØDECaster Pro II setup.
