The Pixel doesn't use Qualcomm's proprietary QuickCharge but standard USB Power Delivery. It can negotiate charging at 9V, 2A (18W). Legacy USB can charge 5V, 2.4A (12W), and regular Type C can charge at 3A (15W). Scaling with power, 15W is 25% faster than USB and 18W is 50% faster. The higher voltage is supposed to charge empty batteries faster. The iPad Pro seems to support quick charging with the Lightning to USB-C cable and MacBook 29W USB PD adapter. And charges about twice as fast (2.5 hr vs 5 hr). |
