USB-C Charging on the PBP?

[moonwalkers]

Power supply specs from the wiki  "USB-C 5V, 15W PD quickcharge" seems incorrect. If it's fixed at 5V then it's not "PD". 

K, the first time I actually played along with this, the second time I just kept quiet, but now I'm actually getting a bit annoyed...

Without PD USB can deliver up to six unit loads for high power SuperSpeed devices, where the unit load is 150mA on USB 3.0 (SuperSpeed) and 250mA for multi-lane SuperSpeed. That means without PD USB can deliver up to 7.5W. USB PD was developed specifically to standardize the way to deliver more than 7.5W of power, and than includes 15W, the maximum power deliverable without increasing voltage. So technically 15W delivery in PBP is USB PD, compliant with revision 2 or 3 of the standard, though saying "quickcharge" is indeed a bit of a misnomer since that would imply a different proprietary technology by Qualcomm that predates USB PD standard and AFAIK is available only on their Snapdragon platform.

That said, IMNSHO 15W is barely adequate for PBP.
