With the Reduction Revolution Power Meter you can measure power consumption and operating cost of any plug-in appliance. It measures:

Watts - Instantaneous power usage.
kWh - Power usage over time (what you are billed for).
Cost - kWh multiplied by your electricity tariff(s).
Other - Volts, Amps, Power Factor, and total Operating 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 standard desktop computer set-up was found to use 22 watts in standby (costing $40 per year when it was not even being used).
Reducing a particular pool pump's run-time by just two hours per day saved $237 per year.
A sound system's sub-woofer was using 10 watts in standby (costing $20 per year unused).
A dishwasher's lower temperature setting used 0.4 kWh less per load saving the household $36 per year.

Power Consumption Meter - Specifications

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. Use it to uncover how much each of your appliances cost to run.

Measures from 1 to 2,400 watts.
Also reports usage in kilowatt hours (kWh).
Tracks actual cost by entering your electricity tariff(s).
Measures voltage, current, Power Factor and frequency (50 or 60Hz).
Displays watts (W) and voltage (V) to one decimal place. It shows kilowatt-hours (kWh) and current in amps (A) to three decimal places.

It also has these additional features:

In-built timer to track appliance run-time.
Replaceable batteries ensure data is not lost when unplugged.
Accuracy of measurements are +/- 1%.
Power consumption of the meter is less than 0.5 watts
It can be used with an extension cord

This is an accurate Power Meter

The 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.

For example, we have seen a 5 watt load displayed as 30 watts on this less accurate power meter.

On the other hand, the Steplight / Reduction Revolution power consumption meter described above has the benefit of being relatively inexpensive and accurate.

Alternative options for extended 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 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?

Only one electricity tariff can be entered. If you are on time-of-use billing we suggest entering an average tariff rate for your premises. See also our 'Wireless Energy Monitors' which can track multiple tariffs for whole-of-site monitoring.

Is the cost set in dollars or cents?

The cost isn’t pre-set to cents or dollars, it is just a number (’00.00′), so you can set it however you like.

For example, if your electricity rate is 20c per kWh we recommend setting the price at ’00.20′ (as in $00.20), rather than ’20.00′ (as in 20.00 cents).

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.
