A power conditioner (also known as a line conditioner or power line conditioner) is a device intended to improve the quality of the power that is delivered to electrical load equipment. While there is no official definition of a power conditioner, the term most often refers to a device that acts in one or more ways to deliver a voltage of the proper level and characteristics to enable load equipment to function properly. In some usages, power conditioner refers to a voltage regulator with at least one other function to improve power quality (e.g. noise suppression, transient impulse protection, etc.).

The terms "power conditioning" and "power conditioner" can be misleading, as the word "power" refers to the electricity generally rather than the more technical electric power. Conditioners specifically work to smooth the voltage of the electricity they supply.

Power conditioners can vary greatly in specific functionality and size, with both parameters generally determined by the application. Some power conditioners provide only minimal voltage regulation while others provide protection from half a dozen or more power quality problems. Units may be small enough to mount on a printed circuit board or large enough to protect an entire factory. Small power conditioners are rated in volt-amps (VA) while larger units are rated in kilo-volt-amps (kVA).

While no single power conditioner can correct all power quality problems, many can correct a variety of them.

It is common to find audio power conditioners that only include an electronic filter and a surge protector with no voltage regulating capability.
