C13 and IEC power cords: a connector family for equipment
C13 is a connector family widely used for computing and office equipment power cords, within the broader IEC connector system. This guide explains that family in general terms. It states no specification for any specific cord.

What a connector family is
A connector family is a standard shape shared across makers, so that equipment, cords and power sources from different sources can connect. The IEC system standardises several such shapes for equipment power, and C13 is among the most familiar: it is the connector buyers most often meet on computer, monitor and office equipment power cords. That familiarity is useful — a buyer who recognises a C13 connector can name it in an inquiry — but it is not a complete specification: cords in the same family can still differ in length, setting suitability and other qualities, and the inquiry should state those alongside the family name.
The IEC family also illustrates a general buying point: naming a connector family answers the fit question, not the whole purchase question. Fit is pass-or-fail — the cord must fit the equipment and the outlet — but the purchase also involves the device, the setting, the distance and the use pattern. A buyer who names C13 and stops there has answered one question of five. The computer, monitor and printer application page discusses the equipment classes that commonly use this family, and the buying guide walks through all five questions in order.
Where C13 cords appear
C13-family cords appear wherever computing and office equipment needs a detachable mains cord: desktops, monitors, printers, and a range of other equipment with a matching inlet. Detachability is itself a benefit: a cord can be replaced without replacing the equipment, a longer cord can substitute for a shorter one, and a cord for one region's outlets can substitute for another's where the equipment accepts it. That flexibility is also a buying trap: a cord that fits the inlet but is wrong for the setting or the distance is still the wrong cord, and a cord bought for one region's outlets should be checked against the outlets it will actually use.
For equipment fleets — offices, schools, workshops with many similar devices — the C13 family offers a stocking advantage: one cord family can serve many devices, simplifying spares. The inquiry for a fleet should still name the device classes, the settings and the distances involved, because a fleet that spans several settings is not one job but several, and the supplier's proposal should reflect that. Quantity discussions for fleets run through the bulk inquiry page.
Buying a C13-family cord
A complete C13-family inquiry names the connector family where known, the equipment class, the setting, the distance along the real route, the quantity in mind and the documents needed — with certificates available upon request and the certificate position confirmed for the proposed item in writing. Order quantity and lead time are confirmed per item before payment. As with every cord on this site, no specification is printed on this page, because the specification that matters is the one confirmed in writing for the specific item proposed.

How to place an inquiry, step by step
- Send the use and the setting. Tell us what the cord will power, where it will run, and how far it must reach — indoors or outdoors, at home, in an office, in a workshop, or beside a vehicle or generator.
- Name the category. Pick one of the four main categories — power cords and extension cords, AC/DC power adapters, DC converter cable, or solar cable — and say whether you need a standard category item or a custom inquiry.
- Confirm specifications and terms in writing. Ask the supplier to confirm the specification of the item it proposes, the order quantity, the lead time and the certificate position for that item, in writing, before payment. Certificates are available upon request.
- Agree the sample step. Confirm whether the next step is a sample of a category item or a discussion of a custom design, and what check you will run on arrival — fit, reach, or behaviour in its real setting.
Send all of this in one message through the contact page: the use, the setting, the distance, the category, the quantity you have in mind, and the documents you need. That is the whole inquiry.
What to send us now
Send one message with the use (what the cord will power), the setting (where it will run), the distance it must cover, the category you need, the quantity you have in mind, and the documents you need — noting that certificates are available upon request. Say whether you need a standard category item, a custom inquiry, or a bulk inquiry. Use the contact page form. A message that specific is what turns four broad categories into a short, answerable question.
