1. Prevent wasting electricity: The power saver box is used to stabilize voltage, balance current, and prevent overvoltage to achieve energy-saving effects. 2. Reliable materials: The outer shell of the power saver device is made of flame-retardant material, and leakage protection measures are adopted inside. When working under rated load, the stored energy will be released in a smoother manner through the spike-free capacitor system. 3. Practical energy-saving device: The power saver itself does not consume electricity, so you can use it to save electricity consumed by household appliances such as refrigerators, air conditioners, TVs, etc. 4. Easy to use: Just plug the power factor saver into the power socket and the green light will light up. Then keep the device connected and it will start working and reduce energy consumption. 5. Wide application: The power saver has obvious effects on air conditioners, washing machines, refrigerators, water pumps, induction cookers, electric kettles, etc., and is suitable for homes, offices, apartments, shops, etc.
