I'm still somewhat new to mining, so I'm starting out with a Satechi 12-port powered hub. I have a total of 13 block eruptors. I can invest in more hubs easy enough. I've reviewed the specifications on the Satechi - each port provides 5 volts, 250 milliamps.
Block Erupters require 500ma. So that is only half the power needed. What is the voltage and the total current of the power supply itself?
If each of 12 ports can get 250ma then *maybe* 6 can get 500ma??
