How many kilowatts does a revon hair dryer per hours?
No device uses "kilowatts per hour". A watt or kilowatt is a unit of power, not of energy. That means that the "per hour" or "per second" is already implied - the watt refers to a "rate of energy conversion" - not to an amount of energy. If a devices uses a certain amount of kilowatts, it uses this amount all the time while it is on - whether it is kept on for a second or for several days.
