A clip to keep the charge cable in place while handling the phone. There are two versions. One for use without a case, and one for use with a slim case. it has only been tested with my Spigen slim case though. Works great when traveling or whenever. I have cheapo cable and it has lost its ability to stay in the phone. This fixes that issue by keeping the cable from backing out of the connector. Tested with both an Apple original cable, and an Amazon basics cable.
