Which power supply does the SP4 i7 ship with?

Been reading that some apps/games will drain the battery when plugged into the charger. I then saw that the SP3 and at least some models of the SP4 come with a 35w power supply.

So what size power supply ships with an i7/16g Surface?

Does the Surface Dock come with a power supply?

Mine shipped with a Model 1625 Charging Supply (*See Specs below) and I have ran a boatload of games and software without the battery draining. Mine seems to be able to keep up with maintaining the battery charge and running my Surface Pro 4, i7, 256 without issues. I haven't encountered anyone else mentioning that their standard charging device hasn't been able to keep up with their machine's demands. However, car charging solutions are a different animal all together.

Not sure as to the Surface Dock.
