How do I know how much power my applicance may need?

Power is measured in watts (W).  Power = Voltage (V) x Currrent (I) = VI

 

For applicances at home, its power ratings are normally in watts (W) or kilowatts (kW). Look at the labels of your appliance. Furthermore, check if it is a household running on alternate current (AC) or direct current (DC) power.

 

If your appliance do not have any labelling that tells you its power rating, do check out any  manuals, specifications or instructions that came with the appliance.
