This step up / step down converter can change 220, 230, 240 volts to 110, 120, 130 volts and visa versa. Simultaneously, the latest smart-logic technology provides multiple layers of regulated electricity while stabilizing the output to 220 volts and 110 volts. That means your equipment will receive constant stable electricity without any electric fluctuation or deviations, keeping your equipment safe against harmful surges, power outages, and voltage spikes. The wide input range of 75 volts ? 130 volts and 180 volts – 260 volts allows for the widest possibilities in stabilized output of either 110 volts or 220 volts +/- 4%.
