I bought these cables for my iPad and decided to try them on my Windows mobile phone. The phone was almost impossible to charge and you had to wind the charging cable in a certain way in order for it to charge. I connected the magnetic cable to the phone and never had a problem again. The USB adapter stays in the phone and I just have to pull up and connect the magnetic cable. I never have to worry about twisted cables. I love this product and the friends I have recommended it to also love the ease of use.
