Measure the power consumption and operating cost of any plug-in appliance with the Reduction Revolution Power Meter. It measures:

  • Watts - Instantaneous power usage.
  • kWh - Total power usage over time (what you are billed for).
  • Cost - kWh multiplied by your electricity tariff(s).
  • Other - Volts, Amps, Power Factor, and appliance Run Time.

The Power Meter will help you uncover your most 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 and associated savings 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 sub-woofer 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 appliance plugged into a standard power outlet. It can also measure a group of appliances plugged into a single power board. 

Power Usage Meter Screen

The Power Meter display screen has three sections as shown here:

1) The top part shows clock time and appliance run time since the last reset. The run time reading only accumulates when power draw is greater than 2W. 

2) The middle part of the screen shows total cost, total kWh used, kgCO2 emissions, and your electricity tariffs as entered. These readings can easily be reset before moving to the next appliance.

3) The bottom part of the screen shows Watts, Volts, Hertz, Amps, Power Factor, Max & Min Wattage, and an overload setting. For everyday usage, all you really need to pay attention to is the "W" reading for Watts.

    This is an accurate Power Meter

    Power Meter AccuracyThe Power Meter pictured on the left has been spotted at major hardware stores, supermarkets 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 sizeable electrical loads (falsely reporting 0 consumption), while others are overstated.

    Alternatives for data logging or sub-metering

    Although this item represents excellent value, it is not the best choice for every power monitoring application.

    • If you're after a professional tool for very frequent usage we recommend the Power Mate Lite.
    • If you actually require a solution to on-bill a sub tenant we recommend one of our electrical sub meters.
    • If you want to capture your entire property's energy usage (rather than individual appliances), then check out our range of wireless energy monitors.

    Power Consumption Meter Support & FAQ

    Does it come with instructions?

    Yes - the unit comes with printed instructions. Click here to download the latest power meter user manual (PDF).

    How accurate are the readings?

    The Power Meter has been tested against high-end power meters such as the Power-Mate (which we also sell). The readings of actual power consumption (Watts) from the Power Meter are comparable to those produced by the Power-Mate. The main difference is that the Power-Mate units produce very high accuracy readings to multiple decimal points and have a different user interface.

    Both units scored highly in a recent power meter review by CHOICE. They also scored first and second place in a review by TechLife.

    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), Power Factor 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

    For example:

    • 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.

    If analysing this information is important to you we suggest buying the Power Mate Lite which displays all of this data (amps, volts, VA, and Watts) on one screen.
