A power source is the origin of incoming electricity, as an outlet, battery, or generator. The power supply works to convert the power from the source into the correct format and voltage.

The specific power supply function depends on whether it needs to regulate energy or convert power. Power supplies have essential functions found in all models but they will also have additional operations depending on the device type.

You might need the power supply to change voltage up or down, convert power to direct current or regulate power for smoother outcoming voltage. These functions will help you choose which supply you need for your electrical needs.
