Monitor your energy usage with this wattmeter socket! Track a device's power (W), energy consumption (kWh), voltage, amperage, hertz, power factor, cost, and minimum/maximum power (W). Easily switch between display modes to view various settings while your device is running. The power consumption meter can calculate and display the power your device consumes and the amount of electricity used over a period of time. The 8-inch display features a backlight for clear data viewing, day or night. A 180° viewing angle ensures you can easily read and record data from any angle. Overload Warning: When the power of the connected device exceeds 3200W or 16A, the LCD screen displays "OVERLOAD" to alert the user and automatically disconnect the power supply to ensure household electrical safety. This function only operates when you reduce or remove the load's power. When the detected power value is less than 1.0W, it is considered local consumption, and the time is not accumulated. This feature is very useful for ensuring power supply safety and saving energy. The next time you use it, you can see the latest data directly, without worrying about data loss due to sudden power outages.
