4.5 (V)
YesINo2.570Yes
Many small switched-mode power supplies used for laptops. Commonly referred to as a "clover-leaf" or "Mickey Mouse" connector due to its shape.​
C7C8 IEC 60320 C7.svg 8.6NoIINo2.570No
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.

C15C16 IEC 60320 C15.svg 14 (H)
4 (V)
YesIYes10120Yes
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.​
C15AC16A IEC 60320 C15A.svg 14 (H)
4 (V)
