What’s the Difference Between C7 and C8 Power Cords? A Complete Guide

The main difference between C7 and C8 power cords lies in the plug type (male/female) and polarity design. C8 is a male connector (with pins), and C7 is a female connector (with holes). Both use an 8-shaped interface and are commonly used in devices like televisions and monitors.

Core Differences Between C7 and C8 Power Cords
Plug Type

• C8:Male (with pins), designed to be inserted directly into the device’s power input.
• C7:Female (with holes), used to connect to a power adapter or extension cord.

Polarity Design
Both are non-polarized connectors (no ground wire), though some manufacturers may modify C7/C8 connectors (such as the custom version for Apple Mac mini).

Application Scenarios

• Universal Devices:TVs, monitors, printers, projectors, and other common devices use C7/C8 power cords, where the C8 plug connects to the socket and the C7 socket connects to the device.
• Specialized Designs:Some small computers (like NUC) or game consoles (like XBOX ONE S/X) may use modified connectors, so compatibility should be checked.

International Standards and Compatibility

• IEC 60320 Standard:C7/C8 connectors are defined under this standard, suitable for non-locking power connections below 250V and 16A.
• Interchangeability:Standard C7/C8 connectors can be interchangeable, but ensure that voltage and current parameters match the device’s requirements.
