open-in-new
<p>A DC connector (or DC plug, for one common type) is an <a href="/facts/Electrical_connector/rJh0cHs6">electrical connector</a> that supplies <a href="/facts/Direct_current/r9MNUx84">direct current</a> (DC) power. </p><p>Compared to domestic <a href="/facts/AC_power_plugs_and_sockets/938U5dTF">AC power plugs and sockets</a>, DC connectors have many more standard types that are not interchangeable. The dimensions and arrangement of DC connectors can be chosen to prevent accidental interconnection of incompatible sources and loads. Types vary from small coaxial connectors used to power portable electronic devices from <a href="/facts/AC_adapter/zyGpmNcX">AC adapters</a> to connectors used for automotive accessories and for battery packs in portable equipment. </p>
