Made by one of the leading manufacturers in the industry, the Seven Star THG 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 THG-300U/D is rated at 300 watts maximum. It features a heavy-duty cord with a standard round prong plug plus a free American Flat outlet plug adapter. There is a input voltage selector on the back of the unit to switch between 110 and 220 volt for the input. The output voltage on the front of the unit is always opposite that of the input voltage selected on the rear of the unit. The output socket on the front panel is universal that accepts both standard U.S and European plugs into it. For extra safety unit has fuse protection system and includes (2) extra fuses.

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.
