If you still need some help in getting exact electricity usage of the devices, here is kuman electricity usage monitor that gives some ideas as to what device or appliance you may want to closely watch. And it is advised to get voltage meter as a pack of 4.

How Many Watts Does An Air Conditioner (AC) Use?

Calculate electricity usage and power consumption of An Air Conditioner (AC). Also know how many watts does An Inverter Aircon use.

If you wish to discover the actual power consumption of the air conditioner (ac) that you have obtained, you must first take a quick peek at the label located at the bottom or the back of the device or appliance.

The electrical ratings will usually be stamped on the label itself, in terms of either Watts (W) or Voltage (V) and Amperage (A).

You can then determine the heater wattage using a simple formula of:

Watts (W) = Volts (V) x Amps (A).

To calculate the consumption of an electrical appliance in kWh, you have to take into account two factors:

  1. The capacity of your electrical appliance expressed in watt.
  2. The number of hours that the appliance is in use in one day.
