Pixel 4 and Pixel 3 A/C adapters - Are they the same?

[PaulQ]

This may be a stupid question and the answer is probably yes. It struck me this morning as I grabbed my Pixel 3 charger and used it on my Pixel 4XL, I don't actually know if there are any differences between the 3 and 4 charger (A/C adapter).

Same, right?

Yep. Both 18 Watt PD 2.0.

What he said...

To expand though, Google's bricks and their phones are following the USB Power Delivery standard... Purposefully avoiding proprietary charging standards like Quickcharge et al... as well as any licensing fees associated with them.

So while it's not as fast as the custom ones, anything that supports the standard will perform to the spec. No 'oh, I didn't bring the right cable/brick with me' nonsense.
