Power supply and power cord for max power setting

摘要

Apparatus, methods, and systems are disclosed for a power supply adapted to receive power from an outlet, the power input having a property, such as amperage, frequency or voltage. An indicator is provided on the connector to the power cord to indicate a value for the property to the power supply, wherein the power supply adapts to the value for the property. By providing an indication of the property the system is capable of reducing functionality to meet the capabilities of the power supply. A power cord may be provided with a male plug at one end capable of being inserted into a socket with a minimum value for a property, and the other end of the power cord may have a connector with an indicator to identify the minimum value for the power cord.
