I would believe it does support it btw, based on this from an Anandtech review of the Lumia 930:
The Lumia 930, with the latest version of Windows Phone, supports Qualcomm?s Quick Charge 2.0 specification which allows a higher voltage charger to be used for much faster charging. The 930 also supports built in Qi wireless charging.
This device may not benefit from it as much as something like the Moto X does, it depends on the battery itself. The higher voltage is misleading because the batteries are all still 3.8V, but they are using a higher voltage through the USB then using a DC-DC converter to step it down. The only reason they do this is because there are limits on how much current a USB spec cable and connector can safely carry. Higher voltage means lower current for the same amount of power.
