The ACUPWR AU-250W Step-Up Transformer is designed to let you use 220-240 VAC appliances in countries with an input source of 110-120 VAC. They offer risk-free operation to ensure the safety of your gadgets and appliances abroad. Made from high-grade copper metal, the transformer is durable and reliable. Rather than play it safe by purchasing a transformer 2 or 3 times the power you need, this transformer performs at its true wattage and will operate at 120% beyond its stated power if necessary. Finally, a thermal protection circuit is used instead of fuses causing the unit to shutdown when it detects excessive heat and restart when it returns to normal operating temperature.
