110V to 220V Voltage Converter Transformer 2000W Step Up/Down 110/120 Volt - 220/240 Volt Converter

[WARNING] For coffee makers, hair dryers, rice cookers, blenders, and other devices over 1000W, a transformer with twice the wattage is required; please use a 3000W model. [Voltage Transformer (110V to 220V, 220V to 110V)] This offers a secure, reliable, steady, and economical solution for converting 110 volts up to 220 volts or 220 volts down to 110 volts. [Multi-function] This voltage converter transformer is appropriate for both residential and commercial uses. It can be used with many kinds of household electrical appliances. Some appliances, such as heating appliances, power tools, coffee makers, and laser printers, need 2-4 times more watts at startup than their printed rated wattage. [Note] Size: 8×6×6 (in). Weight: 10 (lb). The transformer only converts voltage and does not change the frequency (Hz). Please ensure your appliance is compatible with 50/60Hz before use. If the input frequency is 60Hz but your appliance requires a precise 50Hz, it may affect efficiency or produce some noise. [Sockets]: 4 AC outputs. 2 US Standard Sockets for 110-120V appliances and 2 Universal Sockets (accepting all plug types except the large South African plug) for 220-240V appliances. The transformer can be used in countries with voltages of 110V-120V or 220V-240V, such as the US, EUR, UK, CN, HK, and others. [Continuous Operation] High-efficiency toroidal transformer with stable output and low consumption. It has passed the Temperature Rise Test and IEC testing. [Safe] Dual circuit breakers provide protection for each voltage, ensuring safe operation. [Read Before Use] 1) Ensure the power cord is securely connected. 2) Ensure the input voltage selection button on the back matches the actual input voltage
