Features: 2-pack electronic power saver devices designed for households with multiple electrical appliances, helping to stabilize voltage and balance current to prevent voltage fluctuations. Simply plug the power saver into a standard outlet; the green indicator light will illuminate, indicating it is actively working. Helps reduce power consumption when continuously connected. Utilizes a capacitor-based system to release stored electricity in a smoother manner, reducing power spikes during operation under rated load conditions. Constructed with an outer shell made of advanced fire-resistant and explosion-resistant materials. Includes internal protection against leakage for enhanced safety and reliability. Improves power factor and helps prevent electrical overheating during normal operation under rated load.
