Be aware that is 27W charger and that Powercore probably is taken 10W of it, the phone is probably taking 10W also, so there’s probably only 7W remaining for the other two ports. Perfect if you have just say some buds or low power item. But if you had, say, two empty Powercore and a phone, then it’s at it limit.
But 4 ports is also my common need. I tend to use now two dual-port for combined 4 port 48W. Anker doesn’t really make the ideal charger, it’s a mix+match ever since PD came out.
