| Connector | Appliance inlet | Diagram | Pin spacing, centres (mm) | Earth contact | Appliance class | Rewirable connector allowed? | Max. current (A) | Max. pin temp. (°C) | Polarized | Remarks and example uses |
|---|---|---|---|---|---|---|---|---|---|---|
| C1 | C2 |  | 6.6 | No | II | No | 0.2 | 70 | No | Found on many electric shavers, for example. |
| C3 | C4 |  | 10 | No | II | 2.5 | 70 | Yes | Similar connector to C5/C6, but with a key ridge instead of an earthing conductor, withdrawn from standard. | |
| C5 | C6 |  | 10 (H) 4.5 (V) | Yes | I | No | 2.5 | 70 | Yes | Many small switched-mode power supplies used for laptops. Commonly referred to as a "clover-leaf" or "Mickey Mouse" connector due to its shape. |
| C7 | C8 |  | 8.6 | No | II | No | 2.5 | 70 | No | Domestic audio, video, radio equipment and doubly insulated power supplies. C8 inlet is 10 mm deep, C8A and C8B inlets are 15.5 mm deep. Commonly referred to as "figure 8" or "infinity" in the UK. There is a similar polarized connector having one squared side, (see outline below), but this is not part of the standard.  |
| C9 | C10 |  | 10 | No | II | No | 6 | 70 | No | This kind of coupler is used by Roland Corporation for a couple of synthesizer and drum-computer models (for example: TR-909, D-50) and by Revox for many older models of their hi-fi equipment (for example, A76, A77, A78, B77, B225). Was also used heavily on Marantz hi-fi equipment in the 1980s and 1990s. |
| C11 | C12 |  | 10 | No | II | 10 | 70 | Yes | Similar to C9 with a slot in the connector, withdrawn from standard. | |
| C13 | C14 |  | 14 (H) 4 (V) | Yes | I | Yes | 10 | 70 | Yes | Very common on personal computers and peripherals. Commonly referred to as a "kettle cord", but kettles in countries using 120V require the C15/C16. |
| C15 | C16 |  | 14 (H) 4 (V) | Yes | I | Yes | 10 | 120 | Yes | For use in high-temperature settings (for example, electric kettle). Also used in Cisco Catalyst series switches, Cisco MDS9500 series rack-mounted SAN switches,[15] HP Procurve switches, Dell PowerConnect switches and early Xbox 360 power supplies. |
| C15A | C16A |  | 14 (H) 4 (V) | Yes | I | Yes | 10 | 155 | Yes | For use in very-high-temperature settings, such as some stage lighting instruments. Similar to C15/C16, but the top is narrowed to exclude the C15 cord connector. |
| C17 | C18 |  | 14 | No | II | No | 10 | 70 | Yes | Xbox One power supply [16] some vacuum cleaners, CPAP machines, audio equipment, televisions, medical devices, IBM Wheelwriter typewriters. |
| C19 | C20 |  | 13 (H) 8 (V) | Yes | I | Yes | 16 | 70 | Yes | Common for supply of power to enterprise-class servers, UPSes, datacenter rack-mounted power-distribution units and other equipment that draws too much current for C13/C14 type to be used. |
| C21 | C22 |  | 13 (H) 8 (V) | Yes | I | Yes | 16 | 155 | Yes | High-temperature variant of C19/C20 |
| C23 | C24 |  | 13 | No | II | No | 16 | 70 | Yes | Ungrounded variant of C19/C20 |
