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
| Electricity Rate | Set in cents/kWh to 3 decimal places |
| Greenhouse Gas | Set in kg/kWh to 3 decimal places |
| Timer | 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). |
| Cost | $0.000001 – $999999 |
| Energy | 0.0001 – 99999 kWh |
| Greenhouse Gas | 0.00001 – 99999 kg |
| Volts | 170.0 – 270.0 V (RMS) |
| Amps | 0.000 – 10.00 A (RMS) |
| Power | 0.00 – 2,400.0 W |
| Apparent Power | 0.00 – 2,400.0 VA |
| Power Factor | ± 0.001 to 1 (dimensionless) Leading/Lagging |
| Frequency | 45.0 - 65.0 Hz |
| Extrapolated Readings | 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. |
| Direction | A '-' symbol is shown on key readings if power is back-feeding through the meter. |
| Accuracy | Power-Mate accuracy for all ranges is better than 2%. Typical accuracy is within 1%. |

Power-Mate FAQs
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!
