Key Features Build to Last: It is made of high-class iron, copper, silicon steel, and plastic and has undergone a spray molding process, giving it good hardness, durability, scratch resistance, corrosion resistance. High Performance: This 4500W high-power transformer can quickly and stably step up voltage from 100-120V to 200-240V, and step down voltage from 200-240V to 100-120V, providing a reliable and convenient solution for changing voltage. Safety Guard: The overload protection, over-temperature protection, class B insulation level, built-in fuse, and uniform heat dissipation holes can ensure the stability and safety of the product during operation. Application It can be used for most household appliances, such as coffee machines, kettles, rice cookers, juicers, toilet seats, refrigerators, massagers, yogurt makers, etc. Specifications Color: Black Material: Iron, Copper, Silicon Steel, Plastic Process: Spray Molding Shape: Rectangular Mounting Type: Free Standing Plug Type: EU Standard Power Source: Corded Electric Voltage Conversion: Step-Up & Down Outlets: 2 US Output Sockets+ 2 EU Output Sockets Frequency: 50Hz/60Hz Output Voltage: 220V+1-3%, 110V+1-3% Power: 4500W Boosting Voltage Range: 200V-240V Voltage Reduction Range: 100V-120V Product Capacity: 5KVA Working Temperature: -15~45°C/5~113°F Efficiency: 90% Accuracy: +1-3% Insulation Class: B Operating Noise: ＜20dB Power Cord Length: 1m/3.28ft Product Size: 35*25*22cm/13.78*9.84*8.66in Gross Weight: 13.5kg/29.76lbs Net Weight: 12.83kg/28.29lbs Package Size: 43.5*29*25.5cm/17.13*11.42*10.04in Package Included 1* Voltage Transformer 1* English Manual   Notes 1.Please pay attention to heat dissipation and ventilation during use without foreign objects blocking the cooling holes, and keep away from high temperatures, humidity, and explosives. It should be placed in a dry and well-ventilated area at all times. 2.To ensure the normal use of inductive loads, it is recommended to choose a transformer with a rated power of 2.5-3 times the load power.
