Features: 2-pack electronic power saving devices ideal for homes with multiple electrical appliances, helping to stabilize voltage and balance current to prevent voltage fluctuations. Simply plug the energy saver into a standard power outlet; the green indicator light will illuminate, indicating it is actively working to optimize energy usage while connected. The device uses a capacitor-based system to release stored electricity in a smoother manner, reducing power spikes under normal operating conditions. The outer shell is made of advanced fire-resistant and explosion-proof ABS material, with internal safety protections for reliable and secure operation. Helps reduce electrical overheating during normal operation under rated load, enhancing overall circuit safety.
