Thanks for your purchase from Zerolemon and sorry to hear your trouble.

The reason why the item does not support quick charger is to prevent your two devices from heating inside the case together. 

Heat is the number one enemy of the batteries. 

If both were to quick charge at the same time, the life of the battery, not to mention the phone, would be greatly diminished. 

Please just feel free to contact us if you have more concerns about our product.
