Home energy monitoring that shows how much individual appliances draw and what they cost to run. Practical for anyone who wants clearer readings and an early warning about high power draws. Is KETOTEK Power Meter the simplest way to spot waste and avoid overloads?
⚡ At a Glance
- • Measurement Accuracy: True RMS readings for voltage and current, with active power (W), apparent power (VA) and energy (kWh) tracking
- • Best for: Homeowners and renters who want to identify high-consumption appliances and estimate running costs
- • Not ideal for: Users who need a backlit display for reading in dark spaces, as the LCD has no backlight
Plug-in monitor displays kWh, watts, voltage, current and frequency. Adjustable overload and cost alarms help manage usage and warn of excessive loads.
See running costs quickly – thanks to KWh and cost calculation
Five-button interface gives one-press access to different parameters: M shows kWh and electricity cost, + shows active power (W) and apparent power (VA), OK shows true RMS voltage (Vrms) and true RMS current (Arms), - shows frequency (Hz) and power factor (PF), and ↺ reveals max/min power and accumulated time.
Instant cost figures make it straightforward to judge whether an appliance is worth leaving on and where to trim usage.
Avoid dangerous overloads – with adjustable overload alarm
Overload limit is adjustable up to 3680W with a recommended pre-set around 2900W; exceeding the set limit triggers the LCD to display 'Overload' while an LED flashes continuously as a warning.
Clear visual alarms help spot excessive draws before they cause socket or fuse problems, making it easier to protect high-draw appliances.
Keep measurement records through power cuts – with built-in data storage
A high-precision memory chip preserves measurement data during power failures; the unit also allows resetting measurements or deleting data while retaining user settings for easy swapping between appliances.
Saved readings simplify comparison over time and allow quick re-use without reprogramming settings each time an appliance is tested.
✨ The 4 Key Reasons for KETOTEK Power Meter

❓ Frequently Asked Questions
Q: Can the monitor calculate my electricity bill?
A: Yes. Press M to display kWh and the calculated electricity cost so running costs are visible per appliance.
Q: Will the unit cut power if an overload occurs?
A: No shutdown is described; when the load exceeds the set overload value the LCD shows "Overload" and an LED flashes continuously to warn the user.
Q: Will measurement data be lost during a power cut?
A: No. A built-in high-precision chip stores measurement data in the event of a power failure so readings are preserved.
🏆 Our Verdict
The KETOTEK Power Meter suits homeowners and renters who want to pinpoint high-consumption appliances and understand running costs. True RMS measurements, cost display, adjustable overload alarms and data retention make the unit particularly useful for routine checks and swapping between items. Long-term value comes from identifying wasteful appliances and receiving early warnings about excessive draws.
