Power Bright series of step up/down voltage transformers offers you a safe, reliable, affordable and convenient solution to converting voltages from 110-120-Volt up to 220-240-Volt or from 220-240-Volt down to 110-120-Volt for both home use and industrial applications. The VC2000W is rated at 2,000-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 outputs on the front panel. Two are grounded outputs, one designated for 120-Volt with a US standard outlet and 220-Volt only universal outlet. 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.
