So that's the same as your theoretical 11.4W limit.
Thank you very much, megous, for the power draw measurement!
The good news is that the BQ24171 works as configured. That bad news is that the total power draw "from the wall" is much lower than what can be provided by the official barrel port charger or a USB PD charger in its default configuration.
They're both capable of providing 15 W.
