The Nexus 4 wasnt quite the first phone to support wireless charging, but it was a very early example. Google quickly dropped the technology and not long after that, it became a staple of flagships. The search giant may have finally seen the error of its ways as the Pixel 3 and Pixel 3 XL will have wireless charging.
An image of the official charger dubbed Pixel Stand shows that it will hold the phone at an angle to accommodate the Smart Display function. Basically, while they are docked the Pixel phones will display a different UI, one focused on at-a-glance info and easy to hit buttons. The Google Assistant will be front and center.
Google doesnt currently have an answer to Amazons Echo Spot and Echo Show, but this sounds like it could be it.
Anyway, the Pixel 3 duo will reportedly support fast wireless charging. If you look closely at the bottom of the stand you can see 9V 2A (thats 18W), which is likely the power consumed by the charger while the emitted power should be slightly less (15W is the current standard).
Fast wired charging will be supported too (the Pixel 2 phones are capped at 10.5W).
