Goldsource STU-300 Step Up/Down Voltage Transformer Converter - AC 110/220 V - 300 Watt
Made by one of the leading manufacturers in the industry, the Goldsource ST series step up/down voltage transformers offer you a safe, reliable, affordable & convenient solution to converting voltages from 110-120 volts up to 220-240 volts or from 220-240 volts down to 110-120 volts for both home use & industrial applications. The ST-300 is rated at 300 watts maximum. It features a heavy-duty cord with a standard US 3-prong plug plus a free American to German outlet plug adapter. There are a total of two grounded outputs on the front panel, one is designated for 120 volts and the other is for 220 volts only. They both are standard US outlets and can be used simultaneously. For safety, it's recommended by the manufacturer that the voltage transformer's maximum power should be equal or greater than the power rating of your appliance multiplied by 1.5. For example, if you have an appliance rated at 100 watts, you will need to pick a transformer with a maximum power of 150 watts or greater.
