3000W Step Up Down Converter Transformer：80% Maximum Load & Output Voltage Display & Portable Design

This large, heavy, powerful, quiet converter runs all of the appliances I acquired while living in Europe. As the frequency is not converted (in my case its input is 225VAC at 60Hz and its output is 250VAC at 60Hz), items with motors (such as power tools) that expect 50Hz will run faster than designed, while items with resistance (such as my Sigg Raclette grill) are indifferent. Very pleased!. Byron Matthews. Mount Airy, MD. Tue Aug 04 2026

This is a 3000W USB voltage transformer. Input Voltage: 110/220V/AC selectable Output Voltage: 110/220 V/AC, 5V/DC USB Power Cord Length: 3ft 36H Shipping. Note: For safety, it’s recommended by the manufacturer that the voltage transformer’s maximum power should be equal to or greater than the power rating of your appliance multiplied by 2.5. For example, if you have an appliance rated at 100 watts, you will need to pick a transformer with a maximum power of 250 watts or greater. The power of our transformer must be 2.5 times larger than the buyer's appliance to be used normally.
