Step-Up & Down Transformer 450-1000VA

This device is a Step-Up & Down Voltage Transformer, designed to allow you to use electronic devices from one country in another that has a different voltage standard. ​Function ​Its primary job is to "translate" electricity. It converts 110V/120V (common in North America) to 220V/240V (common in Europe, Asia, and HK), and vice-versa. ​Step-Up: If you are in Canada (110V) and want to use a device bought in Hong Kong (220V), you plug the transformer into the wall and use the 220V output socket. ​Step-Down: If you take a Canadian 110V device to Hong Kong (220V), you use the transformer to bring the voltage down to the 110V output socket. ​Capacity: The "450" in the model name likely indicates a 450-Watt capacity. ​Crucial Note: Only use this for devices that draw less than 450W (e.g., laptops, small fans, or phone chargers) The unit includes a fuse.
