Why do my iphone keeps saying charging is not supported with this accessory?

I bought my iphone charger a month ago I have a 3gs. All of sudden it starts to say charging is not supported with this accessory sometimes it will charge and sometimes it won't. Why does it keep saying that, what do I have to do.

Exactly what mine did, I bought a new chord on amazon (only a couple bucks) and never had an issue since. Chords can go bad.

Mine won't work either!

  • Why is iphone saying charging not supported with this accessory? It worked fine last night. Same wire. It only happens when I connect it to the computer which I did last night.
  • Why does my iphone shows that charging is not supported with this accessory? I think I had my phone plugged in to my laptop for more than 2 hours and it hasn't charged fully. It's like 32 percent charged since I plugge it in. And now it says the above question. I don't know why?
  • Why does my iPhone 3 say 'Charging not supported with this accessory'? So recently my ipod got stolen, and my friend decided to give me her old iphone 3 to use instead. I used my old ipod charger with it, and it worked but then i updated the software to iOS 6.1.6 and it wouldn't charge in an outlet anymore, it is only able to charge when i connect it to my computer. I already searched online about this and someone said to put the phone onto airplane mode then charge it in an outlet but that didn't work. Any suggestions?
  • This accessory may not be supported- Charging my iPhone 5? I'm about to ******* slam my phone down, this is Really frustrating i'm not even over exaggerating. Whenever I try to charge my iPhone, I plug in the charger and i have to wiggle it around and then it works, then 2 seconds later it says 'This accessory may not be supported' WTF. I buy my chargers at crackerz bc i don't have enough money to buy one at Telus (I have like no money) And every like, week i have to buy a new one before it breaks. I'm getting pissed
