The connectors will not tolerate more than 3.5a 24x7x365 and even that is pushing them VERY hard. Actual ratings for USB-A connectors is 1.5A continuous and 3.1A for a short time (charging things). Folks have gotten around that by hard wiring 5v power to the power traces after the connector on the stick. I think they went as high as 4 amps using very strong air cooling. It's buried in the Gekko F1 thread.
Thanks for the info! I'd like to see how far I can push them in the current form factor. I have a y split cable with one leg that's power only and the other is data/power. I think it's drawing power from the 3A charging block and maybe the hub as well, but I assume it's around 3A max for both the F and the A1. Got these mostly for fun to get into the mining game - I love the concept of a stick miner, although I do wish they could come in usb-c form factor that can take a little more juice. The A1 is actually reporting under 65-68C in my current setup, so there's headroom there. The F is running on thoughts and prayers.
How did they connect to the traces... soldering or? I'm a little hesitant to actually cut these things.
