wattage rating
  • A rated or named value stating the power, in watts, that a component, circuit, device, piece of equipment, or system can produce, consume, dissipate, or otherwise safely handle, when used in a given manner, or under specified conditions. For instance, the power rating of a speaker may indicate the RMS power that can be delivered to a dynamic speaker for extended periods without harming the voice coil or other components. The peak power rating would specify the maximum power level which can be briefly tolerated without harm.
  • The recommended power, expressed in watts, required for proper operation of a component, device, piece of equipment, or system.
