If you followed the Made By Google event, you could be under the wrong assumption that the Pixel 4 wireless charging speeds are subject to the same restrictions as the Pixel 3. It turns out that isn’t the case and the phone has massively improved in this regard. Looks like we can add another upgrade to the growing list of features the Pixel 4 and Pixel 4 XL ship with.

The Wireless Power Consortium's website details that the maximum Pixel 4 wireless charging speed is 11W, which is a huge improvement over Pixel 3’s 5W speed. More importantly, you can use any third-party fast chargers to get the job done and not just the search giant’s own, which cost a pretty penny. This means you will not be bound to an expensive charging pad to juice up the device.
