+    <para><command>systemd-ac-power</command> may be used to check whether the system
+    is running on AC power or not. By default it will simply return success (if we
+    can detect that we are running on AC power) or failure, with no output.
+    This can be useful for example to debug <varname>ConditionACPower=</varname> (see
+    <citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>).</para>
