USB-ISO is USB Full speed USB 2.0 issolator that protects your laptop from overvoltages and ESD shock. Obvious targets at high voltage are electricity meters. Less obvious high voltage transient targets are those with DC motors and switchmode inductors. Issolators can be useful in low noise audio environments to eliminate ground loops.
Two USB-ISO are shown in the picture to illustrate both the ports, only ONE unit is supplied
