How do you find out how many watts it takes to charge/work an appliance?

and what is the difference between input and output? wich one do you use to figure out how many watts it takes to use appliance?|||look at the book it came with or google it|||your q i cannot figure out .but appliances have markings/stickers so you know the draw! input current is input. output current is output????!!|||Use the input ratings. Multiply the voltage in volts by the required current in amperes (divide by 1000 if it's rated in milliamperes) to get the power requirement in watts.





If it's a refrigerator or something similar with a compressor or big motor, the required power at startup will be considerably more, and then the power drawn by the appliance will drop to the rated level.|||watts are watts W= volts X amps


if voltage goes down and resistance stays the same then amps go up


if voltage goes up and resistance stays the same then amps go down|||6 anus
