I was surprised to see this Watt Power Meter Plug display “OVERLOAD” even when I thought my appliances were well within safe limits. For a moment, I wondered if I’d accidentally set the overload threshold too low, but then I realized how helpful that warning actually was.

It made me rethink how much power some of my gadgets are really drawing.

The large, backlit LCD screen immediately caught my eye. It’s bright and clear, with a generous 2.36 by 1.85-inch display that’s easy to read even from across the room.

No more squinting or bending over to check the numbers in dim light. The wide viewing angles mean I can glance at it from almost any position without losing clarity.

Switching between the seven display modes is seamless, and I love how I can see different parameters like voltage, current, power factor, and even estimated costs all in one place. The ability to track maximum and minimum values helps me spot appliances that are unexpectedly energy-hungry.

The adjustable backlight time is a thoughtful touch. Whether I want it always on or just a quick 10-minute glow, I can customize it without hassle.

The overload protection feature is reassuring, especially for high-wattage devices like space heaters or large kitchen appliances. When overloaded, it halts operation and displays a warning, which is a real safety benefit.

The memory function impressed me most—it remembers your last data even if you unplug it or if there’s a power cut. That’s super handy for monitoring long-term energy use.

Overall, it’s a practical, easy-to-use device that makes managing my electricity consumption straightforward and stress-free.
