Function: 1. MAIN APPLICATION: The function of the energy saving module is voltage stabilization, current balancing and surge protection to avoid inefficient energy wasting. 2. GREEN INDICATOR: Simply plug the power saver into the power outlet, the green indicator light will be on, then start working without plugging in the device. 3. SAFE AND RELIABLE: When the energy saver is operating under rated load, it is safer to use a capacitor system to release the stored energy more smoothly to normal state. 4. ENERGY SAVING: This power saver reduces power consumption and effectively saves energy, up to 20%-35% for heavy loads. 5. APPLICABLE SCENARIO: This energy saver is suitable for houses, apartments, shops, restaurants, hotels, offices and small factories.
