   i made a product that shipped to europe, but first i needed to test it with 220 volt, using this i plugged into my 120 volt wall, then plugged my unit with its europe style 2 round pins into the 220v place on the box. i like the switch and fuse protection, much safer than a raw transformer. i can select this to step-up OR step-down the voltage, careful of the wattage…
