PLEASE NOTE: This product only plugs into 15A outlets, as pictured below. To check a standard 10A outlet, use another power meter.
Power Meter for 15 Amp Sockets
The Power Mate 15 Amp is a precise power meter used for measuring the power consumption of larger 15 amp appliances, including:
- Commercial kitchen appliances (cookers, dishwashers, etc).
- Caravan park and boat marina powered sites.
- Many other devices, including water pumps, computer server equipment, and air conditioners.
15A appliances use high-current sockets with a taller, deeper earth pin, as pictured below. This meter only fits into 15A sockets like these.

15A plugs and sockets have a larger Earth pin.
Measure and Uncover Opportunities to Save Energy from Larger Power Loads
The Power-Mate 15A has similar functionality to the Power-Mate Lite 10A, but in a 15 amp format, capable of measuring loads up to 3.6kW. In addition to accurate power measurement, it displays voltage, current, power factor, and energy. Electricity cost, greenhouse gas readings, and extrapolated readings over hourly, quarterly, or annual time periods can be displayed based on power readings at the time of measurement.

15A Meter FAQs
Can I use it outdoors?
The Power Mate 15A is rated for indoor use only. It should not be used outdoors for extended periods because exposure to weather or moisture could damage the device. If you must use it briefly outside, ensure the display and meter are completely protected from rain, dust, and sunlight in a suitable enclosure.
Can I plug a 10A appliance into this 15A meter?
Yes, but the meter itself will still need to be plugged into a 15A wall outlet because of the larger Earth pin at the back.
Can I plug this 15A meter into a 10A wall outlet?
No, use a regular plug-in power meter for this.
Can I use it continuously on a single device?
Logging usage for multiple hours, days, or even weeks is fine. But for multi-month or yearly metering of a high-usage device, like a 15A EV charger or a lived-in caravan, it is not recommended. We recommend a hard-wired electricity sub-meter for monitoring electricity circuits like these.
