There are actually two things you need in your magnetic charging cable, but they don't do a good job. The magnets are so weak that sometimes just touching the phone will turn them off. And since they may not fall, it may not be noticeable that your phone stops charging. Second, they charge very slowly. Although a magnetic cable, even a wireless connection. I bought them because they were a good price, nice design and good recommendations on review sites. Maybe I just got a pack of four bad flimsy cables. Although I doubt it. I will be returning these cables and looking for another set. I don't like doing it, I'd rather not do it, make it work the first time, but it happens.
