Wattmeter from aliexpress - power meter, voltmeter, ammeter 220 volts, 100A

In this video, I review a multifunctional device from AliExpress that monitors a 220‑volt household network. The device combines a voltmeter, ammeter, wattmeter, electric energy meter, and frequency meter. It features a single button that toggles the backlight, displays power values after a 3‑second press, shows an overload warning, and resets consumed energy after a 5‑second press. The meter retains voltage, active power, amperage, power factor, consumed energy, and mains frequency values even after power loss. The kit includes the wattmeter, an external current sensor, and instructions.
