Both the Pixel 6 and Pixel 6 Pro were assumed to be able to use up to 30W of power in order for their large batteries to top up faster. Unfortunately, that is not the case, according to the latest test results that you are about to see.

To be clear, Google never officially stated that its latest flagships support 30W of fast-charging, only that the battery would reach 50 percent in 30 minutes on the basis that the handsets are connected to a 30W USB-C power brick, which is then plugged into a wall outlet. Even then, the company stated that actual results might be slower. Later, Android Authority performed its own tests to see how the Pixel 6 and Pixel 6 Pro fared. It turns out the figures were different.
