Why does Power Saver save power?Stabilize the voltage, reduce the current, and improve the power factor of the power supply in an all-round way. It can stabilize the voltage and current, reduce the loss of the inactive current on the line, suppress the interference surge, avoid the waste of the ineffective power, and achieve the power saving effect. The appliance protects all appliances, thereby extending the life of all appliances in the home.Power saving function and instructions for use:The voltage stabilizer stabilizes the voltage, prevents the voltage from being unstable, and makes the power consumption stable and balanced to achieve the effect of power saving, thereby prolonging the service life of electrical products.The product is equipped with anti-convex wave device to prevent current convex wave and protect electrical appliances.Electronically control the capacitance, balance the current, improve the power usage of electrical products in an all-round way, and avoid the waste of ineffective electricity.The power saver itself does not consume current, 24 hours 365 days, all-weather use will not increase the burden of electricity bills.Applicable to air conditioners, washing machines, refrigerators, electric fans, TVs, water pumps, stereos, fluorescent lamps and other products.General households, company offices, shops, and small factories are all within the scope of application.Applicable voltage 90V-240V/50Hz-60HzPower SaverThis is a voltage stabilizer that can stabilize voltage, reduce power consumption, and extend the life of home appliances.FunctionBy installing this device, you can avoid invalid power consumption and effectively protect your home appliances.[High performance] Save power, comprehensively improve the power consumption of home appliances, and avoid invalid power consumption.HIGH QUALITYMade of high quality materials, it can work continuously all day in any climate and is very durable in use.[Advantages] It has the advantages of being more stable, safer, more reliable, more efficient and more beautiful.packing list:1* Battery Saver
