hi! great post.
I've got curious and explored for a while that wattage difference, and for now i got the idea that the chargers id's are hardcoded per model, so when IOPSCopyExternalPowerAdapterDetails is called, the key kIOPSPowerAdapterWattsKey haves the right value.

Will look further with more time
