IPhone problem! Won't charge

So about 3 weeks ago I got an I-Charge it's basically a little box where you plug in your phone and it will automatically charge anywhere you are. So I was using it perfectly fine. Today I plugged in my phone and it said 'charging is not supported with this accessory'. My I-Charge works with other iPhones except mine. My iPhone only charges with original charger that came with a phone. Is there anyway I can solve this problem?
