IPhone chargers not working?

There are five people in my family. All of us bought iPhone 4s and chargers about a year ago. Now only one of the chargers work. All of the phones will charge with no problems when paired with the working charger. There was no water damage or unusual harm done to the chargers. Why did all of our chargers break? Is there any way to fix them? How expensive are new ones.

Told him my charger wasn't working, so he went to the front of the restaurant and got a toothpick. Started picking in the lightning charger input, picking out tons of lint.

  • Why is it that my iPhone chargers stop working? I've purchased several chargers this year and after about a month, they stop working and my latest one says that the charger isn't supported with this accessory.Am I buying the wrong charger? The chargers that I buy on amazon say that they can be used for any iPhone or iPod. I have an iPhone 4.
  • Why do iPhone chargers stop working? The original charger I got when I bought my iPhone ripped. I bought another iPhone charger and after a month or so, it stopped working all of a sudden. I disconnected it from my phone, and connected it again and it didn't work. I bought another iPhone charger and it happened the same thing as the second one. It stopped working all of a sudden. Does someone know why?
  • Why do Iphone chargers (especially iphone 5) not last very long? I can never keep a charger more than a couple months without it breaking or ceasing functionality. It doesn't matter if I'm using the charger mostly in the office, in my car, at home, etc. Is this a scheme by manufacturers to keep charger revenue flowing or is this the universe's way of telling me I use my phone too much?
  • Why do all of my iPhone 5 chargers stop working? I've gone through 6 in the past 3 months, I'm buying high quality chargers, but they just stop working after a week or two. Is there something wrong with my iPhone? If i take it in to a repair store will they look at it for free?
