Arnic 628 is a 16 volt dc, maximum 100 watts per seat, dc conversion to
15 volts (aircraft power bus is 400hz 110volt ac) and from 15 to
whatever your laptop requires put the effective power limit at about 75
watts

The approach of the airlines and the faa is to limit the number of
outlets and their variety based on the load that the system can support.
most in-service aircraft simply aren't generating enough power to
deliver it to every seat in the plane.
