Why can't my iPhone charger work?

Ok my iPhone charger won't charge the USB. So I kept wiggling my iPhone and it wud charge. Ok right now whenever I wiggle it it won't charge nothing. I moved it to a couple places and it won't charge. It keeps saying accessory not supported like what's wrong with it.

Borrow a usb cable from a friend and try it - if it works, you need a new cord.

You either have a non-apple brand charger which are sometimes not compatible or its broken. Most likely broken

  • Why won't my brand new charger work on my IPhone? I have an iPhone 4S, I've had it since December 2012. My old charger has broken and I recently got a new one but it won't work in my computer or in the wall. I've cleaned out the charging port from 90% of the dust. I have a fake iPhone charger which I got off eBay, that broke last night but before it broke it would work fine with charging my phone so I don't see why it won't charge now?
  • Why doesn't my iphone 5c charger work? The little bronze pins on the tip of the charger isn't broken or bent, its not my outlet or iphone since I tested it on several outlets and on my laptop. All it does is show the symbol of 'inserting the charger into the iphone' Is it possible that the charger can break if the wire or cable is bent too much?
