A quick play with the Aukey CC-T1 Car Charger and PB-T1 10,000mAh Power Bank which both support Qualcomm's Quick Charge 2.0 system. Faster charging is made possible by raising the USB voltage to 9V or 12V to deliver more power to the device being charged. Using the YZXstudio USB3.0 Power Monitors, I was able to see the voltage climb to 9V.

Please test if the common usb-meters are compatible
what about QC3?
can you send me alink wor the usb amper tester?
Qualcomm said it does not appear that this product has QC2.0 INPUT, but it does have output. Couldn't wait for Julian's full review later.
I'd imagine total voltage would be (voltage of D+) + (voltage of D-). Why isn't it?
Qualcomm is know for not cooperating much with open source community for it's ARM based SOC's so I'm not surprised that the QC thing is not properly documented too.
I don't know about this QC2 thing, but I had read that on these smart charging things, a device sends data through the data pins to the charger, if the charger has a chip capable of understanding the data it switches in the right analog DC voltages on those pins. The device is waiting and if it sees the right voltages on those pins then draws the appropriate current. This relatively strange handshake is so that a charger can be hard wired to a given current with just cheap resistors if it's meant for a specific device.
I presume it's similar for changing output voltages, just the chip in the charger has to change the charger's voltage feedback to change its output voltage.
I've no idea how much of this is true of course.
stupid marketing…
A good (> AWG) cable and you ahve the quickcharge…
Julian, for full reviews please consider recharge from 25% and let see if can run 15W… 4W was bad…
is this quick charge technology aimed at mobile phone devices?
This may be a good buy for me, I use a powerbank to keep my phone topped up while away from power sources and I've just had a look and it seems my HTC M8 supports QC 2.0 and can charge upto 60% in just 30 minutes 😀
Great video, the monitoring device could do with some in depth analysis. A little bit lost on the D+ & D- pins and how it works as a whole.
I noted you will be covering this, great work and as always bring on more.
Well done Julian
