HP L22320-001 is a C5 power cord for connecting compatible equipment to mains power. The HP parts guide identifies this exact part number as the 1.0 m (3.3 ft) premium C5 cord.
This is the United Kingdom version of the cord. Its 1.0 m length provides a short connection between an outlet and equipment with a matching C5 power inlet, helping keep a power setup manageable when the devices are positioned nearby.
The distributor also identifies the connector arrangement as straight. This is a power cord only; the confirmed product details do not specify an adapter or other included items.
