USB chargers designed for apple devices in principle will not supply more then 0.5A to non-apple devices.
You stumbled across an overpriced non-apple device charger. Since your phone can't short the data wires to draw more amperage, it's drawing around 500mAh.
Now, if you pick up the Motorola car charger on amazon for around $5, it would push around 950mAh to your phone, and charge the battery in a true "quickly" sense.
Unless youve tested it, you dont know what its pulling. How do you know the wires arent shorted? How do you know its not fast charging? I have the motorola charger...it didnt even work on the note 1 correctly (pushed 500mAh) vs another charger I had that pushed ~900mAh
