Heavy Duty 5000W 10000W Voltage Transformer Step Up/Down 110V to 220V Converter

The power of our transformer must be 2.5 times larger than the buyer's appliance to be used normally. 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 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. Make sure the appliance to be plugged in uses fewer watts than the transformer's rating. Insert the voltage tap plug (located on the rear of the transformer) into the pair of holes corresponding to the local voltage standard . Check carefully to be sure no error has been made.
