Ridiculously fast charging, plus the ability to use the same charger for both your laptop and your phone.

Being able to consolidate all the chargers I own is an unbelievably exciting promise. That's only an option for me because I use an Android phone.

> Ridiculously fast charging

How much faster are we talking? I haven't seen any numbers with this claim, nor any justification. There are fast charging systems on the market already with Micro-USB. Qualcomm says their quick-charge solution (used in the new Pixel phones) works with A, Micro, C and others.

I'm not sure that's really all that compelling. It's nice, but I don't think it's nearly as nice as, say, my dock working.

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).

My mistake. I was reading an article that claimed that the Pixel was using Qualcomm's tech.
I don't understand this argument. If I'm using my laptop charger, my phone can't use it at the same time. And if I'm not using my laptop charger, it's probably stowed in my bag, and it's a lot simpler to pull out my phone's charger than it is to pull out my laptop charger. So I'm having trouble imagining a scenario where I'd actually ever plug my phone into my laptop charger.
