IQ2 is QC3 basically.
So 30+5x18 = 120W. Currently that is twice the most powerful Anker makes.
Your car charger is 30+3x18=84W.
Your Powercore 10Ah is extremely unlikely to be 30W, that exceeds the safe discharge limits of Lithium which for 10Ah is 20W.
So I suggest, given it way beyond anything Anker currently makes, given you claim it is urgent,you buy something else. Buy two Powerports to get all you need and two Powercore or one of newer ones which do IQ2.
