Do you ever wonder how much electricity your appliances are using?

The solution is here!

1) Plug the watt meter in-between the wall plug and your appliance

2) Immediately see exactly what your appliance is using (in watts)


The watt meter is plug and play. Just plug the cord into an electrical outlet and plug any device (up to 2000W) into the watt meter. If you want to measure multiple devices at once, you can plug an extension cord into the outlet of the watt meter

You can measure the following:

Basic Functions

1) Current Voltage

2) Accumulated Electricity Consumption (Total kW hours)

3) Current Electricity Consumption (Watts being used)

Advanced Functions

4) Electricity Cost

5) Ratio of Operation

    Bad answer to Wilfred unless his units(dwellings) all draw less than 3000Watt! Better to buy normal house meters from electrical wholesaler. Answer:
    You are 100% correct - We should have mentioned that. Please do not use on the units if they draw more than 3000w at any time
