My iphone charger almost caught fire, the cord started melting, why?

In a year i have purchased almost 5 chargers. They will work for a couple weeks or months and stopped working. I'm very careful about unplugging them without pulling them hard. Why is that? I miss my iphone 4:( :( Keeping up with technology has it's downfall!My iphone charger almost caught fire, the cord started melting, why - 1

Is this an APPLE charger or a knock off look alike made in China charger?

I bought it from an Apple boot at the mall.

  • Will this charger cord affect my iPhone? I have an iPhone 5 and I bought a charger cord from Rue 21 because it was cheap. When I plug it in, it gives me a warning that it may not be recognized by the device. Does that mean anything, will it harm my phone at all? I just got a new iPhone because my other one randomly broke, but it wasn't from the cord because I stopped using it a couple months before.
  • Why my iphone 5a says storage is almost full why I've almost nothing? So my iphone 5s says my storage is almost full while pictures is about 800! And I've no music no books and no big apps! This happened before And I tried deleting all pictures and most of the apps but nothing changed! So I had to format & update my phone then it worked… Now it happened again I can't delete my stuff because it's ridiculous! Why do I have to do this while my phone isn't really full:"( Now I have only 251 MB available:"
  • Why is my cord melting? So my iPhone charging cord split awhile back so I put some electrical tape around it thinking that would be a good idea only to discover a week or 2 later the underneath the cord had melted off what should I do
  • Why does my iphone 5 charger cord only work at random times? I bought a $30 10 ft cord from target like 2 weeks ago (i didn't think it would be as bad since it was expensive) and now it has a really weird problem. Sometimes when i plug it into my phone it would work and sometimes it doesn't (it mostly doesn't). I have no idea what the problem is. It isn't the same problem as when i have to bend the cord, its just taking out/putting in the cord.
