Twist-lock plug extension cord adapters are lengths of electrical cable that convert a device's straight-blade power cord plug to a twist-lock plug for use in a compatible outlet receptacle. These adapters lock in place on the plug end to prevent accidental disconnections. They have a locking plug with curved blades at one end and a straight-blade receptacle at the other end that the device plugs into.

Extension cord adapters are lengths of electrical cable used to create compatibility between a device's power cord plug and a power outlet receptacle when they are of different types. These adapters have a plug at one end that connects to the power source and a receptacle at the other end that the device plugs into. They are typically used to supply power to devices in industrial applications, such as power tools and machinery, where a variety of plug types and outlets are common. Limit current to the adapter's lowest rating to help prevent overheating.
