Main highlights

•The voltage converter is capable of either stepping up the voltage from 110-120V to 220-240V or stepping it down from 220-240V to 110-120V. It operates quietly, boasts an elegant design, and is highly portable, making it ideal for powering global electronic devices and small appliances during travel
•Before use in the United States, Canada, Brazil, Japan, Taiwan, and other countries where 110V or 120V is the standard input voltage, the bottom switch must be set to AC117V (a specific designation for this device, representing an input voltage of approximately 110V and an output voltage of 220V). In China, India, and European countries where 220V or 230V is the standard input voltage, the bottom switch must be set to AC230V, representing an input voltage of 220V or 230V and an output voltage of 110V
•Typically, electrical appliances draw a high level of power at the moment of consumption, with a maximum output of 100W. For safety reasons, it is advisable to use electrical appliances that do not exceed 50W in order to prevent damage to the transformer and the appliances themselves
•Please refrain from using high-power electrical appliances, such as hairdryers, coffee machines, air conditioners, induction cookers, water heaters, electric kettles, and rice cookers, in order to prevent damaging transformers and the electrical appliances being used.
•Voltage converters are manufactured with imported materials, high-performance transformers, and precision circuitry. They are mainly used for converting input and output voltages between different countries to meet the needs of various small household appliances, but cannot exceed the rated power. They are convenient to carry. If you have any questions, please feel free to contact us
