The Pixel 6 and Pixel 6 Pro are reported to ship with large batteries, so it makes perfect sense that Google would implement support for fast-charging for both flagships. According to the latest info, 33W of fast-charging will be supported by each model, but the downside is that you will have to purchase a separate power brick.

There are apparently lots of 33W charging bricks spotted at Google’s headquarters, according to information provided to 91mobiles. Unfortunately, the Pixel 6 and Pixel 6 Pro are only going to be tested using those accessories, with the company likely making adjustments if necessary. There is a possibility that Google provides brand new chargers for sale separately after the flagship smartphone family is available to pre-order or goes on sale.
