Using off brand Iphone charger?

Is it true that using an off brand cord to charge your I-phone like destroys the battery permanently? Someone told me this and I'm kind of worried about it.

Do not use a cheap one that you get for like 3 bucks off some jamacian guy on the street. You couldprobably get one for about five bucks with a good brand. There are companies that sell these chargers for cheap such as Belkin and Philips. Some chargers can screw with your battery but the chances are slim to none.

No. But it may not work or be much more inefficient. Thing is Apple chargers are proprietary and they have to pay Apple a royalty to have them work properly.

  • 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 does my brand new iPhone charger make noise? It makes an electrical hissing noise. The charger is close to my bed and it woke me up. (It's 2 am where I live.) I haven't dropped it or anything. This has never happened with an iPhone charger before. It's brand new! );
  • Which off brand lightning charge cable for iPhone should I buy? I have tried the cheaper ones on eBay and one from the tiger store but they wobble in the socket and don't charge it. Can anyone recommend a brand as I don't want to pay for the apple one. (Also it isn't the phone that's faulty as a friends cable worked)
