IEC C18 is a standardized AC power input interface defined by the IEC 60320 standard for household appliance couplers. It is a two-pole ungrounded connector designed to mate with a matching IEC C17 power cord plug, providing a reliable and removable power input point for electrical equipment.
C18 connectors are typically rated at 250VAC/10A (international standard), and in North America, rated currents can reach approximately 15A according to UL/CSA standards. The C18 connector’s compact design makes it ideal for devices that do not require a grounding connection. Common applications include small household appliances, audio/video equipment, game consoles, external power supplies, and lightweight consumer electronics requiring a simple, standardized power input.

C18 FAQ
It’s an IEC 60320‑standard AC power inlet that accepts a matching C17 plug from a power cord. It provides a removable connection for mains power on equipment that doesn’t require grounding.
C18 is a two‑pole, non‑grounded inlet (no earth pin) that mates with C17 power cords. It’s smaller and simpler than grounded types like C13/C14 and is used in lower‑power or double‑insulated devices.
Under the IEC standard, C18 inlets are typically rated up to 10 A at 250 VAC. With North American UL/CSA approvals, they can be certified up to about 15 A at both 125 VAC and 250 VAC.
You’ll see C18 inlets on compact mains‑powered equipment such as audio/video devices, game consoles, small power supplies, and other electronics that do not need a protective ground connection.
No, since C18 is designed as a non‑grounded inlet, it doesn’t provide a safety earth path; it’s used on double‑insulated or otherwise protected devices.
Yes, because it follows the international IEC 60320 standard, devices with C18 can use region‑specific power cords with the correct wall‑plug style while keeping the same C17/C18 interface on the device side.
