Power source

A power source is a source of power. Most commonly the type of power referred to is:

Power (physics), the rate of doing work; equivalent to an amount of energy consumed per unit time
Electric power, the rate at which electrical energy is transferred by an electric circuit; usually produced by electric generators or batteries

PowerSource may also refer to:

PowerSource (phone brand), mobile phone that can make use of both Sprint-Nextel cellular networks
PowerSource (musical group), a Christian music group of the 1980s

Power source may also refer to:

A source of primary energy, an energy form found in nature that has not been subjected to any conversion or transformation process
Energy carrier, or secondary energy, a substance or phenomenon that contains energy that can be later converted to other forms such as mechanical work or heat or to operate chemical or physical processes
- Fuel, a material that stores potential energy in forms that can be practicably released and used for work
- See Energy development for an overview of primary and secondary energy or power sources

or, often more specifically to an electric power source:

- Electricity generation, the process of generating electric power from other sources of primary energy
  - Power station, an industrial facility for the generation of electric power
  - Electric generator, a device that converts mechanical energy to electrical energy for use in an external circuit
- Battery (electricity), a device consisting of two or more electrochemical cells that convert stored chemical energy into electrical energy
Engine, a machine designed to convert energy into useful mechanical motion
Mains electricity or household power, the general-purpose alternating-current (AC) electric power supply
