Track & Predict Energy Costs With Ease
The Power-Mate Lite offers full power, cost, and greenhouse gas metering with outstanding accuracy. It shows instantaneous and cumulative power consumption measurements, running costs, and emissions.
Unlike any other power meter we sell, it also projects key values into the future: per hour, week, quarter and year. This means you can see an estimate for annual energy usage and cost after a relatively short monitoring period.
A simple menu lets you enter your electricity tariff and greenhouse gas values. The Power-Mate Lite also provides additional technical measurements such as supply voltage, current, power, VA, and power factor.

Why Choose the Power-Mate Over Other Power Meters?
We also sell a much lower-cost power consumption meter. While that meter is suitable for many applications, there are several reasons why you may prefer the Power-Mate Lite. These include:
- Higher accuracy readings - more decimal points on readings like Watts and kWh. See the specifications table below for details.
- More measurements - the Power-Mate reports additional metrics like Amps, Power Factor, Apparent Power, and Frequency.
- Easier to use and read - the backlit screen and 'piggyback' style plug and cable allow you to hold the display in your hand when the plug is at floor level.
- Projected readings - the Power-Mate Lite projects its readings out over a year, so you can get a quick idea of the running costs of an appliance without having to do the maths yourself.
As experts in energy efficiency, we have used the Power-Mate Lite regularly for many years. It's a reliable tool for frequent users and those who like higher accuracy and more features.
Power-Mate Lite Technical Specifications
|Set in cents/kWh to 3 decimal places
|Set in kg/kWh to 3 decimal places
|An inbuilt timer shows the total recorded time since the last reset (up to 99 days). Alternatively, a countdown timer can log data for a set period (1, 8, 12, or 24 hours; 2, 5, 7, 14, or 28 days).
|$0.000001 – $999999
|0.0001 – 99999 kWh
|0.00001 – 99999 kg
|170.0 – 270.0 V (RMS)
|0.000 – 10.00 A (RMS)
|0.00 – 2,400.0 W
|0.00 – 2,400.0 VA
|± 0.001 to 1 (dimensionless) Leading/Lagging
|45.0 - 65.0 Hz
|The Energy, Cost, and Greenhouse Gas measurements are shown under Real, Hour, Quarter, and Year. The 'Real' reading is per the current timed period, and the other figures are extrapolated based on this data.
|Last Mode Memory
|Starts in the last used mode when powered on.
|A '-' symbol is shown on key readings if power is back-feeding through the meter.
|Power-Mate accuracy for all ranges is better than 2%. Typical accuracy is within 1%.

Can I use it outdoors?
The Power-Mate Lite is rated for 'indoor use.' It is only suitable for extended outdoor usage if placed in an enclosure to protect it from the elements.
Can I use it continuously plugged into a single load?
Ongoing multi-month metering of a high-usage device, like a water pump or EV charger, is not recommended. We recommend a hard-wired electricity sub-meter for permanent monitoring of devices like these.
Does it work on 15A power sockets?
No - please see the Power-Mate 15A power meter for this.
What makes it 'Lite'?
The Power-Mate Lite is the latest generation of the Power-Mate series. It is both cheaper and better than the original Power-Mate. The original Power-Mate had just a single-line digital display - see the 15A version above as an example.
There are no advantages to using the Power-Mate 10A over the Power-Mate Lite 10A, so we do not sell it. In short, 'Lite' is probably the wrong suffix - maybe they should have used 'Pro' instead!
Working fine, cable is too stiff, difficult to handle
I was looking for something that allows me to gauge how many Amps per appliance. I have a few commercial kitchenware that may draw high ampere so it was important to check and this nifty gadget made it possible. Ready to use out of the box and it came with an easy to read manual.
Menu can be a bit hard to navigate, but just a matter of getting used to it.
Hi GM, Thanks for the feedback. We'll look for ways to improve the info available on navigation.
The zoom feature is ideal, especially when you are in low light conditions in a carpark, for example. We use it to measure the Energy going into our EV as an interim solution before our apartment gets proper charging facilities.
Power-Mate Lite 10 Amp Power Meter
Excellent screen, amazing detail.
Simple and reliable. I bought this on the advice of others that have used them, and whilst the trend info etc would be useful from the cheaper plug in Bluetooth / WiFi options, I wanted the simplicity and accuracy on offer with this unit.
This things works really well. Would be good if you could save real time data to a usb for export.
PowerMate Lite 10A does a good job. Being able to run the meter for a week or two gives a 'real world' view of average power usage and cost for devices that are used intermittently.
Lots of information displays and easy to use. I love it!
