Reduction Revolution Plug-in Power Meter
Uncover how much your appliances really cost to run
Our Power Meter measures the energy consumption and running cost of any standard plug-in appliance. It measures:
- Watts - Instantaneous power usage.
- kWh - Total power usage over time (what you are billed for).
- Cost - Based on your electricity tariff(s).
- & More - Volts, Amps, Frequency, Power Factor, & KgCO2.
The Power Meter will help you uncover your energy hungry appliances. Then you can get started on reducing your power bills!
You could save $100's by using this Power Meter
Here are some energy guzzlers we identified with this power consumption meter:
- A desktop computer was found to use 22 watts in standby (costing $50 per year, when it was not even being used).
- Reducing a pool pump's run-time by just two hours per day saved $250 per year.
- A sound system was using 10 watts in standby (wasting $20 per year).
- A dishwasher's lower temperature setting used 0.4 kWh less per load saving the household $40 per year.
How to use the Power Usage Meter
This power meter measures the power consumption of any device plugged into a standard power outlet. It can also measure a group of appliances plugged into a single power board.
The Power Meter display screen has three sections as shown here:
1) The top of the screen shows the time of day, as well as how long the meter has been running.
2) The middle part of the screen is labelled 'COST'. It shows total cost, kWh, KgCO2, and your tariff rates.
3) The bottom part of the screen is labelled 'ENERGY'. It shows usage in Watts, Volts, Amps, Frequency (Hz), Power Factor, and Min & Max Wattage.

This is an accurate Power Meter
The Power Meter pictured on the left has been spotted at major hardware stores and online. It is usually priced between $20 and $40. But, it is not reliably accurate (and the screen is hard to read). It can miss large loads (falsely reporting 0 consumption), while others are overstated.
Alternatives for data logging or kWh sub-metering
Here are some other products we sell for related power monitoring applications:
- The Power Mate Lite 10A is a professional tool for frequent usage.
- The Power Mate 15A meter is for larger 15A power sockets (used by some caravans, electric vehicles, commercial kitchens, and others).
- Our hard-wired electrical sub meters are best if you require a solution to on-bill a sub tenant.
- Our wireless energy monitors will capture your entire property's energy usage.
Power Consumption Meter Support & FAQ
How do I use it?
Please see our online power meter usage guide for set-up instructions and usage suggestions.
How accurate are the readings?
The Power Meter has been tested against high-end power meters such as the Power-Mate. The readings of actual power consumption (Watts) from the Power Meter are comparable to those of the Power-Mate.
What is the lowest power consumption it can measure?
The lowest readings we have seen are for small power supplies (about 0.5 to 1 Watt). The Power Mate Lite, on the other hand, will read down to 0.01 Watts.
How many tariffs can be entered?
Two tariffs can be entered.
Does the Power Meter measure Real Power?
Yes - the Power Meter measures ‘Real Power’ – which is what you are billed for. Power is measured instantaneously in Watts (W) and over time in kilowatt-hours (kWh). Other cheap power meters do not perform measurements accurately and do not always display real power.
The power meter will show you (among other things): Volts (V), Amps (A), and Real Power (W). This is how you calculate real power in watts (don’t worry, the meter does this for you!)
- Volts x Amps x Power Factor (as a fraction of 1) = Watts
- 250 volts x 0.7 amps x 0.60 power factor = 105 Watts (Real Power)
- 250 volts x 0.7 amps = 175 VA (Apparent Power)
You can see from the above example why getting this calculation right is important. Other power meters sometimes fail to do this correctly.
