For the price a miracle that it still works

Property me the charging cable bought 4 months ago, as my old all have a loose connection. Since I'm a bit stingy I wanted something cheap and nice. Cable found. Delivery went super.
First problem on the cable, it makes noise, so a slight beep when it is in the power socket and the mobile phone is not even think about it. Meanwhile, it makes the sound but also when the phone is off (but not so loud), but is rather the fact that the cable is a few mm can pull out when connecting to the USB port. The sound, however, is generally not noisy and just at the beginning a bit disturbing when sleeping directly loads the mobile phone beside her and it is not used. What I find also negative is that it loads very slowly. Did it once with the charging cable compared to my mother and find the need to this on my phone (Sony Xperia L) yet twice invites so slowly, but enough if you do not hurry. Over time, it will not charge, however, is too weak or when I write on the phone during charging. Therefore, I would say 3 stars. A cell phone charger was not supposed to be used during charging. The price of the cable was also cheap, so it does its job well enough already and still holds, what I did not expect. But you still have a great prefer to spend 10-20 more and to buy a that loads faster, especially for sophisticated phones.
