A MacBook Pro 16″ wants about 96 W and a Steam Deck about 45 W. Plugged in together they need 96 W + 45 W on two ports at once, which is a different question from "is it a 141 W charger". Most multi-port chargers split power unevenly, so we check the manufacturer’s own split table for every product below.
MacBook Pro 16″: 140 W only with an EPR charger and cable.


"Split not published" means the maker sells a multi-port charger without saying how it divides power. We do not guess; the data score on the right tells you how much of the record is sourced.
