Link USB power strips for a cluster?

[shanefe]

So Im thinking of building a Pine64 cluster for a homelab over a Pi for a couple reasons, also being able to order more than one of the same type.
Their website sells USB to barrel power adapters awesome! But I need a power strip that can output 5V 3A for at least four USB ports.
I am not honestly that familiar with power usage and finding pieces but I see a lot of 2.4Amps with a max total of 12Amps. Out of a USB power strip. Is 3A really just 2.4?

USB-A has a max of 2.4A, you need USB-C to get 3A
