Appliance Energy Monitor for Household Use - 

Simply plug this energy saving power monitor into a powered mains socket and then plug your appliance into it. The meter will monitor the energy usage of your appliance. The Energy Saving Power Meter will measure the energy use (and calculate costs) of running household appliances. This helps you lower your power bill and reduce carbon emissions, as you discover which appliances are the worst energy offenders and then work out ways to limit their use. You can plug any 13A rated household appliance into this power meter in plug adaptor format to access its energy consumption and carbon footprint.
