Im thinking of building a Pine64 cluster - Theirat1991 - 01-11-2024
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?192.168.0.1 routerlogin 192.168.l.l

2.4A is already over the design spec for USB-A if my memory is correct.
If you need 4x3A, you may be better off "homebrewing" something with a 5V15A regulated supply, 4 3A fuses and 4 "barrel plug" cables. Otherwise just use 4 "barrel plug" wall warts. There's no real advantage in using USB for this, IMHO.
USB-C is different, and was actually designed with high current in mind. But I have no idea what's available for that, or if it even makes sense to use it, because a lot of USB-C power is delivered at higher than 5V. I'm pretty sure none of the Pine devices can take advantage of this.
