4-port conversion connector compatible with multiple DC plugs. Set of 4 types. As I do not have product knowledge, I recommend that those who know how to use it purchase it. From the left in the second photo, there are the markings "H", "G", and "C". * This product is an outlet item, so it does not have a dedicated package. Also, the package may have tears, dirt, and sticky residue from stickers. Since we have not tested the operation, we cannot guarantee its functionality. Please understand this before purchasing.
